How to read a yaml or env file using bash

Question

I have a .yml file and it has content like below:

env_values:
 stage: build
 before_script: some-value

So I need to read and get the values for stage and before_script, so they will have build and some-value respectively.

Is there a good easy workaround in bash scripting to read this file and get the values?

Assume your .yml file is t.yml, this Bash script gets the 2 values you need:

arr=($(cat t.yml | grep "stage:"))
stage=${arr[1]}
echo $stage

arr=($(cat t.yml | grep "before_script:"))
before_script=${arr[1]}
echo $before_script
