How to source an sh file in a pod to create env variables?-CodePudding

I have a pod with multiple init containers and one main container. One of the init container create a sh file with some export commands like:

export Foo=Bar

I want to source the file so it creates the env variable like this:

 containers:
    - name: test
      command:
        - "bash"
        - "-c"
      args:
        - "source /path/to/file"

It doesn't create the env variable. But if I run the source command directly in the container it works. What is the best way to do this using the command option in the pod definition?

CodePudding user response：

Kubernetes configmap can used to have the key values as env variable inside a container.

CodePudding user response：

Instead of using the init container, you can directly use the configmap or secret to inject the variables as environment variable into pod.

So your script will be able to access those variables directly.
