/retitle Advice on setting environment variables for a process in a container

Hey @xlouba, you can find about setting env variables and use them with the bash commands here -
https://kubernetes.io/docs/tasks/inject-data-application/define-environment-variable-container/#using-environment-variables-inside-of-your-config

You can also try like this -

In terminal -

1. Setting environment varible -

export hello="cat demo_greeting.md"

2. Invoking it -

$hello

In k8s Yaml -

# setting env variable
env:
    - name: DEMO_GREETING
      value: "cat demo_greeting.md"

# Invoking it
command: [$DEMO_GREETING]

You can also try like this -

In terminal -

1. Setting environment varible -

export hello="cat demo_greeting.md"

2. Invoking it -

$hello

In k8s Yaml -

# setting env variable
env:
    - name: DEMO_GREETING
      value: "cat demo_greeting.md"

# Invoking it
command: [$DEMO_GREETING]

Thanks! However, it seems that definitions like this in yaml can only execute commands, rather than assigning the results of command execution to variable DEMO_GREETING. Is there any way to assign the results of command execution to environment variables?

Hi @xlouba, then u can use it as

export DEMO_GREETING=$(cat demo_greeting.md)

Ok, I see. I will take this way. Thank you!
