Create a Service Account to access Jenkins with cli

Created by Tass Skoudros, Modified on Fri, 13 Oct 2023 at 07:37 AM by Tass Skoudros

  • Step 1: Create a service user account in the Servana Identity Service admin console. 
  • Step 2: Log in to Jenkins with the service account and create an API Token.

  • Step 3: Create a role in Jenkins for the service account with the least privileges principle. Manage Jenkins -> Manage Roles.

  • Step 4: Assign the new role created in Step 3 to the service account via the assign role menu in Jenkins. Assign Role Link.

  • Step 5: Execute the Jenkins cli with the API Token and service user login information.

A link has been kindly shared of a resource that wraps the Jenkins CLI in a shell script. Here is a link to a gist which makes this process easier.

# Jenkins-cli wrapper see.
# .installation:
#    curl -o ~/bin/jcli-wrapper 
#    chmod +x  ~/bin/jcli-wrapper
# .usage:
#    jcli-wrapper Jenins-URL file-with-credentilas
# .example:
#    jcli-wrapper $(realpath ~/.rcjenkins/jenkins) list-jobs
# .tip:
#   you can create own wrapper with pre-defined values like:
#   #file: ~/bin/jcli
#   #!/bin/bash
#   jcli-wrapper $(realpath ~/.rcjenkins/jenkins) $@
# .note:
#   content of  ~/.rcjenkins/jenkins is:
#   {username}:{token|password}
#   user:123456
shift 1
shift 1

if [ ! -f ~/bin/jenkins-cli.jar ]
    mkdir -p ~/bin
    curl -o ~/bin/jenkins-cli.jar $jenkins_host/jnlpJars/jenkins-cli.jar

java -jar ~/bin/jenkins-cli.jar -s ${jenkins_host} -webSocket -auth @${passwd_file} $@
