Remote Execution Jobs using non-root user are failing with Error "Failed to initialize: Dynflow::ExecutionPlan::Steps::Error - Job execution failed"

Solution Verified - Updated

Environment

  • Red Hat Satellite 6

Issue

  • When running a remote execution job to execute a Command using a non-root user, the job is failing with Error " StandardError Job execution failed "

    Failed to initialize: Dynflow::ExecutionPlan::Steps::Error - Job execution failed

  • SSH connection is working fine from the Satellite Server to Content Host using non-root user, but remote execution is not able to execute a job.

Resolution

  • Change the permissions of the remote working directory mentioned in "/etc/foreman-proxy/settings.d/remote_execution_ssh.yml" file.

    # ls -ld /var/tmp

  • Create a new directory e.g. /remotedir and set the value of remote working directory in "/etc/foreman-proxy/settings.d/remote_execution_ssh.yml" file to the new directory as shown below:

    :enabled: https
:ssh_identity_key_file: /usr/share/foreman-proxy/.ssh/id_rsa_foreman_proxy
:local_working_dir: /var/tmp
:remote_working_dir: /remotedir    <<<<<<<<<<<< Change this directory location as per client system settings

  • Restart the satellite services to reflect this change:

    # satellite-maintain service restart

Root Cause

  • Non-root user doesn't have the permission to create a directory under '/var/tmp', and hence was not able to initiate the job.

Diagnostic Steps

  • Check the log file /var/log/foreman-proxy/smart_proxy_dynflow_core.log .
