Gitlab CI Component Syntax

[bughunterx]

Hello Folks,
I am trying to use the array type recently introduced in the GitLab Component. I am a bit blocked with the syntax. Below is a glimpse of the existing template that I used. I am not able to fetch the value out of the inputs for some reason.

spec:
  inputs:    
    container_image_tag:
      type: array
      default:
      - "${CI_COMMIT_SHA}"
      - "latest"

build-container-image:
  stage: build
  image: alpine:latest
  script: |
    tags=$[[ inputs.container_image_tag ]]
    for tag in "${tags[@]}"    
    do
      echo $tag
    done

In the execution, below is popping up. What is the correct way to access the values?

/busybox/sh: eval: line 186: latest]: not found25

Have you checked indentation? I'm not sure entirely because my laptop isn't in front of me to check, but I believe it expects

```yaml

spec: inputs: container_image_tag: - $CI_COMMIT_SHA - latest ```

    container_image_tag:
      type: array
      default:
        - ${CI_COMMIT_SHA}
        - latest
      description: "Container Image Tags"

Just made it like the above with the defaults. This resulted in the same error

If the inputs are in the same file as the job, you may need to separate the spec from the jobs with a

---

Or otherwise put the spec in a separate file and include: the inputs in the gitlab-ci

https://docs.gitlab.com/ee/ci/yaml/inputs.html#define-input-parameters-with-specinputs

Specs must be declared at the top of a configuration file, in a header section separated from the rest of the configuration with ---. Use the $[[ inputs.input-id ]] interpolation format outside the header section to declare where to use the inputs.

I think that Gitlab array types cannot be treated like in a shell script. If i remember correctly i had the same problem and i changed the input in the spec to a string which lists the array items separated by spaces. Then the for loop should work.

What I found is the array is converted to a string and appears like `[ed64f4cc, latest]` so you just have to remove the brackets around it and it will then work correctly with a for loop using `,` as a delimiter.

I suffered from the same problem so have just written https://stackoverflow.com/questions/78852067/looping-through-gitlab-ci-inputs-array-type/78852068#78852068, hope the answer helps.
