在 bash 脚本中交叉使用 yml 变量

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?

Answer 1

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.
