Issue
Can you pass a binary from a Jenkins host to an agent?
I've got Jenkins running in Kubernetes, and the terraform plugin installed on my Jenkins master with the binary located at /var/jenkins_home/tools/org.jenkinsci.plugins.terraform.TerraformInstallation/terraform/terraform
I would like to pass this to my Jenkins agent by configuring my pod template and mounting the host volume path /var/jenkins_home/tools/org.jenkinsci.plugins.terraform.TerraformInstallation/terraform/terraform to the agent's path /usr/bin/terraform
But this doesn't seem to work as expected
When I exec into the agent and run a terraform version I get the error bash: terraform: command not found indicating that it doesn't have the binary.
I can see a terraform directory mounted in /usr/bin but without the binary. What I expect is for terraform to be installed on the agent. But my thinking might be incorrect here.
Is it possible to do this, has anyone has any experience with this?
Solution
As a @David Maze mentioned binary from Jenkins needs to be manually installed on every node, which can be a difficult to manage. However you can set Jenkins to run pipeline steps inside a container where the image contains the tools you need, which simplifies such case.
