Where does go job take the environment variables from?

When I execute the printenv command on the go-agent

go@05f749b73185:/tmp$ printenv
HOSTNAME=05f749b73185
SHELL=/bin/bash
USER=go

But when I execute the printenv command from inside a job i get this result

    If you look at the JAVA_HOME environment variable it’s different between the job call and the call directly when you’re logged in the machine.
    This can be solved by setting the environment variable in the pipeline, but how can I configure my go-server and go-agents so I don’t have to do this? What if I want to use another JDK as default?

    Where does that JAVA_HOME environment variable come from?

    Have you checked /etc/default/<agent-name>
    In this file you can define the default values for an agent and you can also define environment variables using export command.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
