A Jenkins Admin can execute groovy scripts remotely by sending an HTTP POST request to /script/ url or /scriptText/.

curl example via bash

curl -d "script=&lt;your_script_here&gt;" https://jenkins/script
# or to get output as a plain text result (no HTML)
curl -d "script=&lt;your_script_here&gt;" https://jenkins/scriptText

curl submitting groovy file via bash

curl --data-urlencode "script=$(&lt; ./somescript.groovy)" https://jenkins/scriptText

curl submitting groovy file providing username and password via bash

curl --user 'username:password' --data-urlencode "script=$(&lt; ./somescript.groovy)" https://jenkins/scriptText

Jenkins CLI offers the possibility to execute groovy scripts remotely using groovy command or execute groovy interactivelly via groovysh.

java -jar jenkins-cli.jar -noCertificateCheck -s https://10.0.0.91/ groovy disableEnableJobsMatchingPattern.groovy jobPattern=build_git_auto disableOrEnable=disable --username 12345 --password banana

Configuring NFS to access the files from remote Linux machine as a mount point

by scmgalaxy KJanuary 9, 2018February 27, 2021Unix - LinuxLeave a Comment

I have a 2Tb of storage on a linux box, and i want to use that storage as a mount point from another machine.

As a root user on the remote machine, specify the mount point details

$cat /etc/exports

/scratch *(rw)

/fusionapps *(rw,no_root_squash)

And restart the NFS

sudo /etc/rc.d/init.d/nfs restart (All services should be in running condition)

sudo /etc/rc.d/init.d/nfs status (All services should be in running condition)

And on the local machine, perfrom the following steps

1. Create the stage dir under / as a root user and assign 777 permissions

2. Ad the entry to /etc/fstab file

slcai664.us.oracle.com:/fusionapps /stage nfs rw,hard,nointr,rsize=131072,wsize=131072,timeo=600,noacl,noatime,nodiratime,lock 0 0

3. Then try “mount -a”

If there are any mount point issues, say even as root user, you are not able to modify the files

Unable to mount Read-Only file System

then use

sudo mount -n -o remount,rw /

How to Trigger builds remotely in Jenkins?

1. Create a user – You need to create a user in jenkins using you would like to trigger a jenkins jobs from remote loction or script

How to create users in Jenkins?

Manage Jenkins –> Manage Users –> Create User

2. Assign a right privillage to the specific user?

How to assign privillage to the user?

Manage Jenkins –> Configure Global Security –> Enabled “Anyone can do anything”

Manage Jenkins –> Configure Global Security –> Configure “Matrix-based security” for the specific users and assign atleast following Permissions.

Overall – Read

Job – Build

Job – Read

Job – Workspace

3. Find out jenkins user “API Token”

How to find jenkins user “API Token”?

“

Click on the user name located at top right(e.g http://54.171.140.1:8080/user/admin1/) –> Configure –> Locate the “API Token” section.

4. Enabled “Trigger builds remotely” in Jenkins Job Configuration.

Click on the desired job –> Configure –> Locate the “Trigger builds remotely” under “Build Triggers” Tab

Enabled the check box of “Trigger builds remotely”

Provide some Authentication Token e.g – iFBDOBhNhaxL4T9ass93HRXun2JF161Z

$ Save

5. Formulate the command to run using curl.

> curl –user userid:API-Token http://IP OR HOST:PORT/job/JOB_NAME/build?token=Authentication_Token

eg.curl –user admin1:91367cf0389eaf89669f74c9963c9fb3 http://54.171.140.1:8080/job/ANT-BUILD/build?token=iFBDOBhNhaxL4T9ass93HRXun2JF161Z

Some of other formats which is being tried in google but need to be tested with specific users. there are working with “Anonymous”

> curl -X POST http://admin1:91367cf0389eaf89669f74c9963c9fb3@54.171.140.1:8080/job/ANT-BUILD/build?token=iFBDOBhNhaxL4T9ass93HRXun2JF161Z

> wget http://admin1:91367cf0389eaf89669f74c9963c9fb3@54.171.140.1:8080/job/ANT-BUILD/build?token=iFBDOBhNhaxL4T9ass93HRXun2JF161Z

WORKING WITH NEW JENKINS
> wget –auth-no-challenge –user=admin –password=5ad344f0518640f62d0483084bb889bc http://13.126.143.49:8080/job/ANT//build?token=iFBDOBhNhaxL4T9ass93HRXun2JF161Z

If you are using wget 1.11 against Jenkins version 1.586 and above with the JENKINS-25169 fix, you might need to use the following options:
wget –auth-no-challenge –http-user=user –http-password=apiToken –secure-protocol=TLSv1 http://jenkins.yourcompany.com/job/your_job/build?token=TOKEN

If you are using wget 1.11, you might need to use the following options:
wget –auth-no-challenge –http-user=user –http-password=apiToken http://jenkins.yourcompany.com/job/your_job/build?token=TOKEN

With wget 1.10.x the following is enough (but will not work with 1.11.x) :
wget http://user:apiToken@jenkins.yourcompany.com/job/your_job/build?token=TOKEN

If you are a Windows User!

‘gitbash’ is a program combined of git and bash. A bash is shell that runs commands once you type the name of command and press enter. 🙂

Download the git bash from here https://git-scm.com/download/win and install it.
