Pass binary from Jenkins host to agent

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?

One alternative is to use the slaves setup plugin. We use it to install and configure internal tools (and end) on nodes bases on labels. A log less hassle than @Malgorata's (and our previous) manually copy approach

Not sure how well it works with Kubernetes as not in our configuration.

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.
