How can I add emoji in buildkite-agent step update "label"

General

Is there a way to add emoji in the label when using buildkite-agent step v3 | Buildkite Documentation to update a step at runtime please? When I add an emoji (e.g. :docker:) I got a mapping values are not allowed in this context error, tried to add a \ to escape the :, but got same error. :thinking:

Hi @Wei! Welcome to the community!

The step update command should allow you to update with an emoji, are you able to share the exact command you are running?

Thanks!

Hi @jeremy, thanks for getting back to me. :smile: Below is my step:

- label: ":docker: configure image tag"
    key: tag:create
    commands:
      - TAG=$(some commands)
      - buildkite-agent meta-data set "TAG" "\${TAG}"
      - buildkite-agent step update "label" ":docker: TAG=\${TAG}"
    agents:
      queue: ${BUILD_AGENT}

Please let me know if you are unable to reproduce. If so, it might be some wrapper or settings on our end.

Hi @Wei !

So you can get it working by running the step like this:

  - label: ":docker: configure image tag"
    key: tag:create
    command: |
      TAG=$(echo "newtag")
      buildkite-agent meta-data set "TAG" "$$TAG"
      buildkite-agent step update "label" ":docker: TAG=$$TAG"
    agents:
      queue: ${BUILD_AGENT}

You just need to escape the variable reference, with $$TAG and change the command step to a multi-line command step with command: |
