Tag name with variable

[ojio-san]

Hello,

here is a part of my .woodpecker file :

## webapp
when: [...]

variables:
  - &date_var: &date_var
    - echo $(date -u +'%Y.%m.%d')

steps:
  build:
    image: "woodpeckerci/plugin-docker-buildx:2.2.1"
    secrets: [ docker_username, docker_password ]
    settings:
      registry: ${MY_REGISTRY}
      repo: ${MY_REGISTRY}/webapp
      dockerfile: webapp/Dockerfile
      tags:
        - ${CI_COMMIT_SHA:0:8}
        - latest
      context: webapp/

For this image, my tags are (for example) "a5fa810b" and "latest", but I would like to get the following tags :

- a5fa810b-2024-01-12
- latest

Question : How should I concat the ${CI_COMMIT_SHA:0:8} and the *date_var to get a5fa810b-2024-01-12 ?

Maybe something like this, even if I know that the date can't be called here, that's just the principle :

variables:
  - &custom_tag: ${CI_COMMIT_SHA:0:8}-$(date -u +'%Y.%m.%d')

and

      tags:
        - *custom_tag
        - latest

Best regards and thank you :)

The pre-processor is currently not able to do sth like you tried / suggested with echo date.

a configuration itselve should !! never !! be turning complete!!

@ojio-san as for your problem ... I'm afraid you have to wait for #2254 to be implemented.

@ojio-san what you can do: create a step who generates a .tags file ...

## webapp
when: [...]

steps:
  create-container-tag:
    image: alpine
    commands:
     - echo  "$(date -u +'%Y.%m.%d')" >> .tags
     - echo "${CI_COMMIT_SHA:0:8}" >> .tags
     - echo latest >> .tags
  build:
    image: "woodpeckerci/plugin-docker-buildx:2.2.1"
    secrets: [ docker_username, docker_password ]
    settings:
      registry: ${MY_REGISTRY}
      repo: ${MY_REGISTRY}/webapp
      dockerfile: webapp/Dockerfile
      tags_file: ".tags"
      context: webapp/
