Which is better for automation: Ansible, Chef or Puppet?

by kumarmanishAnsible / Chef / PuppetLeave a Comment on Which is better for automation: Ansible, Chef or Puppet?

Many organizations are increasingly adopting the new collaborative culture in a way to achieve a competitive edge in modern IT domain.

Recent studies shows that the global DevOps market size reached USD 5.8 billion in 2021 and is projected to attain USD 14.97 billion by 2026 with a CAGR of 19.1% during the forecast period.

There are a number of latest DevOps configuration tools such as Chef, Puppet, and Ansible with various features available in the market. So, there is an inevitable need for the comparison of various configuration tools to identify the best tool for the success of DevOps projects.

What is Ansible?

Ansible is a latest configuration management tool which makes configuration management and coordination system of computer very easy to user.

What is Puppet?

Puppet is the oldest version of configuration management system and hard to understand for user.

What is Chef?

Chef is newer than Puppet but older version than Ansible so it is easier than Puppet but not than Ansible configuration system.

Here we do comparison of the top configuration tools including Ansible, Puppet and Chef:

First of all these tools are simple to use and robust capabilities to automate complex multi-tier IT application environment.

The differences between Ansible, Chef and Puppet are portrayed on the basis of different factors including Availability, Configuration Language, Setup and Installation, Ease of Management, Scalability, Interoperability, Tool Capabilities and Pricing:

IT departments with a strong DevOps workflow deploy software 200 times more frequently, with 2,555 times faster lead times, recover 24 times faster, and have three times lower change failure rates.

Conclusion

As you can see above, chef and puppet are the old players with the time whereas Ansible is new players in the market, and Ansible looks very promising with the growing trend. So, to conclude, all the three tools have their own advantages and categories in which they are better than the other. My only intention here is to help you in your decision making. So, it is necessary that you choose the appropriate tool which can be fitted according to your needs.

If you want to know more about Ansible, you can check out this blog on Ansible, Puppet and Chef with complete information.

If you are curious to learn and make a good career with this skill then I would suggest you please check out DevOpsschool.com.

OFFERINGS/ACTIVITIES/PRACTICES UNDER SCM/BUILD/RELEASE/DEPLOYMENT
I am in the process of making a list of Offerings/Activities/Practices under SCM/build/release/Deployment area.

Can some someone please suggest some of those Offerings/Activities/Practices which come under SCM/build/release/Deployment.

i have attached a some of the listing in the document.

NAME OF THE TEAM WHICH HAS CM, BUILD, RELEASE, APPOPP AND DB ENGINEER
Hello Folks,

I am looking for ideal NAME OF THE TEAM which has CM, Build, Release, AppOpp Support and Database engineers. Few people Suggested that it should be DevOps and some of them voted for EnterpriceAppOps Team. What is the naming convention is being used in your company? Please comment for new name as well if you have some idea.

ESCAPING A PASSWORD USING MYSQLDUMP CONSOLE
when you use the quotes, make sure there is no space :
between -p and ‘PASSWORD’ or
between –password= and ‘PASSWORD’

correct:
mysql -u root -p’PASSWORD’
mysql -u root –password=’PASSWORD’

does not work:
mysql -u root -p ‘PASSWORD’
mysql -u root –password = ‘PASSWORD’

you can also define a variable and then use it for the command (still with no spaces in between) MSQLPWD=’PASSWORD’
mysql -u root -p$MSQLPWD

RELEASE VERSION PORTAL
Hi,

We have a complex product architecture having multiple integrated component making a complete solution.

Each component has its own development team and which provide their delivery to release management team

We have catered the version numbering system where all components are sent under one version in incremental manner.

Now in order to provide the high level visibility to the management about what version of which component is running in QA staging and prod i need to have url based dashboard.

How can achieve this using any simple free tool which enable the font end data form entry , and when someone click on specific version hyperlink it should redirect to release notes of that version in SharePoint.

We tried creating list in SharePoint but it didn’t work as we need environment name as columns and components as rows against which we have to enter version number in the grid table as hyperlinks.

something like

QA staging Prod
Component A 1.7.4 4.24.4 1.4.5
Component B 3.46.5 3.5.7 3.5.7
Component C 3.6.5 3.5.7 2.6.7

PUPPET
As anyone worked on puppet Configuration Management tool? Can you please provide the complete details about that or point me to any web portal which contains details except puppetlabs.com

CANNOT OPEN THE DISK
Earlier my disk was full and my VMware stopped working.

Later when i start my VM after disk cleanup, i am getting following error. any idea?
Cannot open the disk ‘C:\Windows XP Professional-000002.vmdk’ or one of the snapshot disks it depends on.
Reason: The specified virtual disk needs repair.

BEST PRACTICE IN BRANCHING
Git does not dictate a process, so usually each project does. Common featurs:
–> Branch for features
–> Branch for fixes
–> Branch for experiments

Any example?

Which can be preferd shell or perl for build and release carrer?

HOW TO HIRE THE BEST WEBSITE DESIGN COMPANY.
Once a business has been developed and set up properly, the need for a website arises. The website is the online identity of a company and it is necessary that you hire an experienced and professional website design company who can complete the task perfectly. While looking for the best website design company you should compare the prices as well as services offered by the various companies in the market. Before hiring a website design company, it is necessary to assemble the various ideas or thoughts of what your business needs and requirements are. Even if you have already hired a web designer, you still need your website to project your ideas. Creating a list of ideas and services that you plan to offer through your site is a good idea so that when you hire the design company, you are already prepared.

You should also make sure that the company you hire has a good track record in terms of customer satisfaction. This can be done by asking your friends who have utilized the firm’s services or by reading customer reviews online. Checking out their work portfolio can give you a better view of their work quality and their individual style. You can choose the services of a firm depending on whether or not the services offered meet your requirements and specifications and whether that design company has the ability and talent required to design your website you are thinking of.

COMPONENT OBSOLESCENCE TRACKING
Often obsolescence management is confined to availability of parts, but the issue of obsolescence management goes beyond. There are key issues related to it- design for the longest possible product life cycle, availability of electronic parts, skills to modify the product, product knowledge, system and domain, tools to modify the product and continuing Electronic Security and Support Issues. While the product is being designed it is important to identify the parts that pose the greatest obsolescence risk. Component Obsolescence Management has to be balanced against product features.

For example, opto-electronic displays (LCDs, OLEDs) commonly tend to become obsolete quickly despite big promises made by their vendors. The design phase will result in a list of parts that are at risk for obsolescence. A proactive approach must be taken to manage these at risk parts. This is possible only if the product is part of an expensive long life cycle product. An estimate is prepared for the requirement of at risk parts for the entire life cycle and these parts are procured. This is a costly process and it is important to correctly identify the risk parts and limit the procurement to them. It is also important to store the parts acquired properly. A less costly approach for handling at risk components is to do obsolescence tracking for them. For critical components, it is essential that the availability be proactively checked every month. Thus, you will want to buy enough components to make sure your product stays in production while your engineering team redesigns the product to not use the part about to go obsolete.

EC2 FTP CONNECTION PROBLEM – WINDOWS INSTANCE –
We’re trying ftp connection from EC2 ftp client to external our server.
But we encounterd the following ftp connection problem.

We need to solve this problem.
We are very much appreciated if you could give us the solutions.

1. Problem
EC2 ftp client fail to conect to ftp Server ,
pwd or cd command can work, but ls, put and get comand cannot work.
We need to use Windows ftp command for connection.
ftp client is EC2 and have Elastic IP address
ftp server is on our office side and have grobal IP address.

2. ftp client Environment
Amazon EC2
Windows 2003 Server Instance
Windows ftp command
EC2 Elastic IP address – zz.zz.zz.zz
EC2 Internal IP address – aa.aa.aa.aa
We used EC2 as ftp client, not ftp server.

3. ftp Server Environment
ftp server is on our office Japan.
it have a grobal IP address xx.xx.xx.xx.

4. firewall security on our office
Our office -> EC2(internet) : all tcp permitted
EC2(internet) -> Our office: tcp20/21 permitted.

5. EC2 security group setting.
tcp20/21 from any IP permitted

6. EC2 ftp client Log
ftp> open xx.xx.xx.xx
Connected to xx.xx.xx.xx
220 ftp server ready.
User (xx.xx.xx.xx:(none)):
—> USER yyyyy
331 Password.
—> PASS ecopass
230 User yyyyy logged in super!
ftp> cd LogFiles\DayLog
—> CWD LogFiles\DayLog
250 CWD command succesful.
ftp> ls
—> PORT aa,aa,aa,aa,9,134
200 PORT command successful.
—> NLST
150 ASCII data.

xx.xx.xx.xx means that ftp Server grobal IP address
aa,aa,aa,aa means that EC2 Internal IP address

7. ftp Server ftp log
Session 7, Peer xx.xx.xx.xx ftp Server session started
Session 7, Peer xx.xx.xx.xx ftp Server session started
Session 7, Peer xx.xx.xx.xx USER xxxx
Session 7, Peer xx.xx.xx.xx 331 User name ok, need password
Session 7, Peer xx.xx.xx.xx ftp: Login attempt by: xxxx
Session 7, Peer xx.xx.xx.xx PASS XXXXXXX
Session 7, Peer xx.xx.xx.xx 230 User logged in
Session 7, Peer xx.xx.xx.xx ftp: Login successful
Session 7, Peer xx.xx.xx.xx PORT aa,aa,aa,aa ,5,106 <- EC2 Internal IP Address Session 7, Peer xx.xx.xx.xx 200 PORT command successful. Session 7, Peer xx.xx.xx.xx NLST Session 7, Peer xx.xx.xx.xx Could not connect to peer. Aborting transfer. Session 7, Peer xx.xx.xx.xx 226 Closing data connection Session 7, Peer xx.xx.xx.xx QUIT Session 7, Peer xx.xx.xx.xx 221 Service closing control connection Session 7, Peer xx.xx.xx.xx ftp: Connection closed. 8. reason why It seems that EC2 Internal IP address is used when ftp Server tried to tansfer data to EC2 ftp client by TCP20. We tried ftp PASSIVE mode by literal command, but rejected by ftp Server. ftp> literal pasv
—> pasv
502 [pasv] Command not implemented.

W need to solve this problem.

Thank you for reading.

LOOKING FOR SUGGESTIONS FOR BUILD JOBS
Looking for suggestions for build jobs using Mercurial MQ

Hello

I’ve recently setup matrix projects to test Py libs (so far axis are
the version of the interpreter and versions of dependencies) .
Considering the fact that Hudson Mercurial plugin doesn’t provide
explicit support for MQ (AFAIK) I’m looking for suggestions so as to
find ways to work around this limitation in order to achieve the
following

1. First of all I’d like to test each and every revision
committed to the repository . I think this could be
achieved by parameterizing the build job and
supplying individual revision number
to the build in the Hg hook that triggers it
from remote (is there a better way to do this ?)
2. I’d like to start a variable number of jobs , more
precisely one job for each patch in the queue .
The goal is to ensure that every patch will work
if applied against repository trunk (have
no idea of how to do this …)
3. I need to copy some (script) files to the workspace
before starting the build (and I don’t use neither Ant
nor Maven, nor MSBuild, nor … I just need to copy
static files ;o) .
4. I need to publish in the build results page
some files generated
during the build (binaries, logs, … ) and browse
(some of) them inside Hudson site . They should
be accessible from the page showing build results
e.g. myserver.com/job/jobname/49

(I suppose this is the «Archive the artifacts» +
«Files to archive» combination … isn’t it ? )
5. I need to execute custom scripts only if the build
succeds.

Please ideas and suggestions about how to do this (and probably
plugins that need to be installed, …) will be very welcomed.

Thnx in advance !

Top Questions on Server Configuration Management Tools Chef, Puppet, and Ansible

by scmgalaxy KConfiguration Management ToolsLeave a Comment on Top Questions on Server Configuration Management Tools Chef, Puppet, and Ansible

 

server-configuration-management-tools-chef-puppet-and-ansible

Source – http://hub.scalr.com/blog/top-questions-on-server-configuration-management-tools-chef-puppet-and-ansible-2

As a quick recap, configuration management tools enable companies to standardize and automate their infrastructure. Through standardization, you can build systems that are platform independent (i.e. instead of relying on AMIs or provider specific toolsets). These tools also make it easy reproduce servers for scaling or testing, and recover from disaster quickly by defining a proper application state. For example, if servers are not in that defined state when each server is checked, they are restored to their proper state. In addition, this standardization makes it easy to onboard new developers.

While the language across configuration management tools is different, the concepts are the same. At the fundamental level in each configuration tool, a resource represents a part of the system and its desired state, such as a package that should be installed, a service that should be running, or a file that should be generated.

In Chef, a recipe is a collection of resources that describes a particular configuration or policy. These collections are called playbooks in Ansible, and manifests in Puppet. These collections describe everything that is required to configure part of a system. Collections install and configure software components, manage files, deploy applications, and execute other recipes. We go into more detail in our blog post here.

Here are the top questions we got from the community:

How is the concept of master/agent configuration better (or not) than agentless, when it comes to infrastructure as code?

Chef and Puppet are master/agent configuration systems, while Ansible is an agentless system. The historic argument is that the agent-based installation process is difficult –  you have to set up the master, and then set up the agents on your nodes so that they know about the master. If you’ve got servers with diverse linux distros, on different versions of Windows, etc., installation can get tricky. Though, because they’re logging every few minutes, agent-based systems are powerful for advanced monitoring. At the end of the day this really is based on personal preference and what company requires. If your infrastructure is beefy and heavily standardized, installation on nodes isn’t complicated so use agent-based systems. If you have servers that run Python, try agentless.

Are these configuration management systems like MicroSoft System Center Configuration Manager (SCCM) but used for local and cloud?

This is like MS SCCM, but open-source and paid for per node. For those who haven’t used it, MicroSoft System Center Configuration Manager (SCCM) is used for infrastructure provisioning, monitoring, and automating workflow processes (usually sysadmin stuff). SCCM is a powerhouse in the enterprise space. While it can manage end clients on non-Windows servers, the server console portion of SCCM must be hosted and run on a Windows server machine. The reason other orchestration/configuration systems win here is that you pay on a per-node basis and you’re not totally tied into Windows Server’s licensing agreements. In other words, open-source vs proprietary. And with Chef/Puppet/Ansible the thinking is more in resources as opposed to SCCM, which is more in files and terminal commands.

An attendee commented on using SCCM:

 “We really like Ansible because of the none-agent requirement. For Windows patching we utilize System Center Configuration Manager, and even though System Center can provide patching to Linux we have run into issues with SCCM agent staying healthy and running on our Linux systems. We have also run into when the SCCM admins have made changes it broke SCCM agent on a majority of our Linux servers. Our Linux patching process has been highly manual up to this point but we are seeking to automate this to free up staff time to be better directed at other support tasks, which is why were are reviewing several solutions. The non-agent aspect is highly desirable in our situation because of past experience with SCCM agent. I just wanted to provide that feedback so others that have not experienced agent issues with other deployment solutions may want to keep that in mind.”

If we have to pick a tool dependent on whether we deploy on cloud or on-premise – which of these tools would be a better choice?

We would recommend looking into network access requirements for each tool. If you have an agent that checks in periodically with a central master management piece, that is likely to work better then SSH which requires direct path / path through lots of proxies. 

One attendee mentioned in the comments: “[In regards to] SSH vs Agent – Agent is more secure where SSH not an option.”

What happened to cfengine? This tool used to be mentioned alongside Chef and Puppet. 
Version 3 of cfengine is a complete revamp, but it compared to other configuration management tools the brand and community outreach isn’t strong, and does little the others don’t do better.

How does StackStorm compare to the other orchestrators being reviewed?
StackStorm labels itself more of an automation platform, or a DevOps workflow tool that handles provisioning and configuring servers but also leans on automatic and event driven services that plugs into Jenkins and other CI/CD workflows.

From one attendee that had used all three: “For us, getting the Server engineers to adopt Chef has been very difficult. It grew organically on the Dev side of the house. Ansible appears to be something that guys without Dev skills could pick up more easily. Just [my] perception.”

Can I run tasks in parallel with Ansible rather than running it serially (say 50 servers being updated with a patch)?

The default method is to run each task across all servers in parallel, meaning that it will run the first task (e.g. installing Git) on all servers in a group, and once all servers respond with a success, failure, or unchanged response, Ansible will move to the next task on all servers. It doesn’t run on a server, wait, move on to the next, it will run on all servers at once over SSH. If you want to deploy updates in batches, you can run a percentage of servers in a group (e.g. 50%, by listing it in the playbook as serial: 50%).

An attendee made this comment as we mentioned Ansible:

“I have attended a presentation from RedHat regarding Ansible that states [that Ansible scales well]. They have large scale hosting companies that on the fly spin up servers and perform patching for their servers via Ansible. The one mentioned had over 50,000 servers and it seemed to handle the volume / scale fine. I of course don’t know everything about Puppet or Chef or Salt, but one thing I find really nice about Ansible is the ability to perform rolling updates / tasks. So if you say had 1000 servers you can say you want to run 10% or 100 at a time and keep it rolling until all 1000 are done. It can be stated by percentage or defined number…I am sure I sound a bit biased but one of the main reasons Ansible is high on our list right now is the fact that it is agentless and does not really consume resources.”

With Ansible, how can we handle the security implications about allowing passwordless ssh to a root account on all systems? What mechanisms are there for access control and auditing?

There are definitely security implications if you are going to allow passwordless ssh. So it’s on the company to ensure that security groups or NSGs are well defined. We should also mention that the passwordless ssh is only enabled on the machine you are running Ansible commands and playbooks from, so if anything consider that workstation to be your weak point. Make sure SSH access is only permissible through your IP. As an alternative solution to connecting via SSH, if you use docker, Ansible allows you to deploy playbooks directly into Docker containers using the local Docker client. All you need is a user inside that container.

Does ansible run single-threaded or is it addressing multiple servers in a group asynchronously?
Ansible runs on each host in parallel. This means that it attempts to run your tasks on all servers defined at the top of the playbook before moving on to the next task.

One user said in regards to all three tools: “Ansible seems better for “orchestration” and Puppet/Chef are really good for “Configuration Management”.  Ansible can be used to stop applications and databases and then run Puppet and then start applications and databases.”

Lastly, we got a surprise question from the audience on Jenkins, a CI/CD pipeline tool that can be used in conjunction with tools like Chef to completely automate the infrastructure behind your applications.

What is the alternative of Jenkins?
While we recommend Jenkins, If you’re a Ruby shop, Capistrano is geared towards your deployments. If you live in the AWS world, you can try using the CodeCommit/CodeDeploy/CodePipeline toolset. If you’re looking for a provider agnostic solution, CircleCI is great. If your workflows revolve around Atlassian, try Bamboo. 

If you are unsure of what CI/CD pipeline tool to use, or how they work, we will be hosting a webinar on Jenkins as part of our on-going series on infrastructure-as-code.

How to Setup Puppet Learning VM – Complete Process/Guide

by scmgalaxy KPuppetLeave a Comment on How to Setup Puppet Learning VM – Complete Process/Guide
setup-a-puppet-learning-vm
Download the VM(Zip File here)

 

Minimum requirements

  • Internet-enabled Windows, OS X, or Linux computer with 10GB free space and a VT-x/AMD-V enabled processor.
  • Up to date virtualization software. See the setup instructions below for details.

Setting up the Learning VM

  1. Before beginning, you may want to use the MD5 sum provided at the VM download page to verify your download. On Mac OS X and *nix systems, you can use the command md5 learning_puppet_vm.zip and compare the output to the text contents of thelearning_puppet_vm.zip.md5 file provided on the download page. On Windows systems, you will need to download and use a tool such as the Microsoft File Checksum Integrity Verifier.

  2. Get an up-to-date version of your virtualization software. We suggest using either VirtualBox or a VMware application appropriate for your platform. VirtualBox is free and available for Linux, OS X, and Windows. VMware has several desktop virtualization applications, including VMWare Fusion for Mac and VMware Workstation for Windows.

  3. The Learning VM’s Open Virtualization Archive format must be imported rather than opened directly. Launch your virtualization software and find an option for Import or Import Appliance. (This will usually be in a File menu. If you cannot locate an Import option, please refer to your virtualization software’s documentation.)

  4. Before starting the VM for the first time, you will need to adjust its settings. We recommend allocating 4GB of memory for the best performance. If you don’t have enough memory on your host machine, you may leave the allocation at 3GB or lower it to 2GB, though you may encounter stability and performance issues. Set the Network Adapter to Bridged. Use an Autodetect setting if available, or accept the default Network Adapter name. (If you started the VM before making these changes, you may need to restart the VM before the settings will be applied correctly.) If you are unable to use a bridged network, we suggest using the port-forwarding instructions provided in the troubleshooting guide.

  5. Start the VM. When it is started, make a note of the IP address and password displayed on the splash page. Rather than logging in directly, we highly recommend using SSH. On OS X, you can use the default Terminal application or a third-party application like iTerm. For Windows, we suggest the free SSH client PuTTY. Connect to the Learning VM with the login root and password you noted from the splash page. (e.g. ssh root@<IPADDRESS>) Be aware that it might take several minutes for the services in the PE stack to fully start after the VM boots. Once you’re connected to the VM, we suggest updating the clock with ntpdate pool.ntp.org.

  6. You can access this Quest Guide via a webserver running on the Learning VM itself. Open a web broswer on your host and enter the Learning VM’s IP address in the address bar. (Be sure to use http://<ADDRESS> for the Quest Guide, as https://<ADDRESS> will take you to the PE console.

 

Troubleshooting

For the most up-to-date version of this troubleshooting information, check the GitHub repository. If nothing here resolves your issue, feel free to email us at learningvm@puppetlabs.com and we’ll do our best to address your issue.

For issues with Puppet Enterprise that are not specific to the Learning VM, see the Puppet Enterprise Known Issues page.

The cowsay package won’t install

The Learning VM version 2.29 has an error in the instructions for this quest. The cowsay package declaration should includeprovider => 'gem', rather than ensure => 'gem'.

If you continue to get puppet run failures related to the gem, you can install the cached version manually: gem install /var/cache/rubygems/gems/cowsay-0.2.0.gem

I completed a task, but the quest tool doesn’t show it as complete

The quest tool uses a series of Serverspec tests for each quest to track task progress. Certain tasks simply check your bash history for an entered command. In some cases, the /root/.bash_history won’t be properly initialized, causing these tests to fail. Exiting the VM and logging in again will fix this issue.

It is also possible that we have written the test for a task in a way that is too restrictive and doesn’t correctly capture a valid syntactical variation in your Puppet code or another relevant file. You can check the specific matchers by looking at a quest’s spec file in the ~/.testing/spec/localhost/ directory. If you find an issue here, please let us know by sending an email tolearningvm@puppetlabs.com.

Password Required for the Quest Guide

The Learning VM’s Quest Guide is accessible at http://<VM's IP Address>. Note that this is http and not https which is reserved for the PE console. The PE console will prompt you for a password, while no password is required for the Quest Guide. (The Quest Guide includes a password for the PE console in the Power of Puppet quest: admin/puppetlabs)

I can’t find the VM password

The password to log in to the VM is generated randomly and will be displayed on the splash page displayed on the terminal of your virtualization software when you start the VM.

If you are already logged in via your virtualization software’s terminal, you can use the following command to view the password: cat /var/local/password.

Does the Learning VM work on vSphere, ESXi, etc.?

Possibly, but we don’t currently have the resources to test or support the Learning VM on these platforms.

My puppet run fails and/or I cannot connect to the PE console

It may take some time after the VM is started before all the Puppet services are fully started. If you recently started or restarted the VM, please wait a few minutes and try to access the console or trigger your puppet run again.

Also, because the Learning VM’s puppet services are configured to run in an environment with restricted resources, they are more prone to crashes than a default installation with dedicated resources.

You can check the status of puppet services with the following command:

systemctl --all | grep pe-

If you notice any stopped puppet-related services (e.g. pe-puppetdb), double check that you have sufficient memory allocated to the VM and available on your host before you try starting them (e.g. service pe-puppetdb start).

If you get an error along the lines of Error 400 on SERVER: Unknown function union... it is likely because the puppetlabs-stdlib module has not been installed. This module is a dependency for many modules, and provides a set of common functions. If you are running the Learning VM offline, you cannot rely on the Puppet Forge’s dependency resolution. We have this module and all other modules required for the Learning VM cached, with instructions to install them in the Power of Puppet quest. If that installation fails, you may try adding the --force flag after the --ignore-dependencies flag.

I can’t import the OVA

First, ensure that you have an up-to-date version of your virtualization software installed. Note that the “check for updates” feature of VirtualBox may not always work as expected, so check the website for the most recent version.

The Learning VM has no IP address or the IP address will not respond.

If your network connection has changed since you loaded the VM, it’s possible that your IP address is different from that displayed on the Learning VM splash screen. Log in to the VM via the virtualization directly (rather than SSH) and use thefacter ipaddress command the check the current address.

Some network configurations may still prevent you from accessing the Learning VM. If this is the case, you can still access the Learning VM by configuring port forwarding.

Change your VM’s network adapter to NAT, and configure port forwarding as follows:

Name   -   Protocol - HostIP -   HostPort - GuestIP - GuestPort SSH        TCP        127.0.0.1  2222                 22 HTTP       TCP        127.0.0.1  8080                 80 HTTPS      TCP        127.0.0.1  8443                 443 GRAPHITE   TCP        127.0.0.1  8090                 90

Once you have set up port forwarding, you can use those ports to access the VM via ssh (ssh -p 2222 root@localhost) and access the Quest Guide and PE console by entering http://localhost:8080 and https://localhost:8443 in your browser address bar.

I can’t scroll up in my terminal

The Learning VM uses a tool called tmux to allow us to display the quest status. You can scroll in tmux by first hitting control-b, then [ (left bracket). You will then be able to use the arrow keys to scroll. Press q to exit scrolling.

Running the VM in VirtualBox, I encounter a series of “Rejecting I/O input from offline devices”

Reduce the VM’s processors to 1 and disable the “I/O APIC” option in the system section of the settings menu.

Still need help?

If your puppet runs still fail after trying the steps above, feel free to contact us at learningvm@puppetlabs.com or check the Puppet Enterprise Known Issues page.
