Is it possible to use dynamic variables in .gitlab-ci.yml?

Question

For example, I want to store some results from API call:

variables:
  DYNAMIC_VAR: $(curl http://ifconfig.me)

Answer 1

Unfortunately no, you cannot do this.

If you only need to use this var in a single job, then it's simple:

job:
  script:
    - DYNAMIC_VAR=$(curl http://ifconfig.me)
    - echo "Using $DYNAMIC_VAR here ..."

However if you need to pass this var between jobs, at the moment it's not directly possible, but you can do it via artifacts.

Answer 2

You will have to use Artifact or Cache if you have to use this information in other jobs otherwise above answer is the perfect solution.
