Cross using yml variables in the bash script

Question

Below I have shown my .gitlab-ci.yml file:

variables:
  timezone: "Europe/Vienna"

stages:
  - style
  - build

style:
  stage: style
  script:
  - sudo docker run --rm -v $PWD:/code omercnet/pycodestyle

build:
  stage: build
  script:
    blla blla
    - sudo docker exec ${CI_PROJECT_PATH_SLUG} /bin/bash -c "./install.sh"
    blla blla

Next, it is my install.sh script:

#!/bin/bash
blla blla 

echo -e "\nmx_download_url: https://dl.bintray.com/random" >> /etc/random-installer/setup.yml
sed -i s+old text+new text+g etc/random-installer/setup.yml

blla blla

How I can use the value of the variable timezone from the yml file in the new text in the bash script?

Unfortunately didn't work. Maybe my bash it's different from perl and doesn't recognize those functions... — , Oct 03 '20 at 19:30

timezone is visible as environment variable for the gitlab jobs, however install.sh scripts is running from another context - it's executed by docker. Docker itself has access to $timezone, however containers it's operating with don't.

To solve your problem you can explicitly pass it:

- sudo docker exec -e TIMEZONE=$timezone ${CI_PROJECT_PATH_SLUG} /bin/bash -c "./install.sh"

This will set environment variable $TIMEZONE for install.sh inside the container.

So I need to set TIMEZONE as an env variable in my runner then associate it in this command with the timezone variable within the yml file? Did I understand it correctly? – Oct 04 '20 at 09:30
`envrionment:` section in `.gitlab-ci.yml` is already defining environment variables for your jobs, that's why I used `$timezone` (lowercase) in my example. I put value from environment section (`$timezone`) into environment variable inside docker container (`$TIMEZONE`). After replacing `sudo docker exec ...` by the example I provided you will be already able to use `$TIMEZONE` inside `install.sh`, no extra changes are required. – Ilia Kondrashov Oct 04 '20 at 09:43
