GitHub actions

local environment variables

set and get/use local environment variables within the workflow. let's say you want to run a curl command in GitHub actions to get a version number and use it later on.

the example below will get the latest version of syncthing and put it into the environment variable SYNCTHING_VERSION, it can then be read with: ${{ env.SYNCTION_VERSION }}

- name: get latest syncthing version
  run: |
    echo "SYNCTHING_VERSION=$(basename $(curl -fs -o/dev/null -w %{redirect_url}" >> $GITHUB_ENV

- name: build syncthing container
  uses: docker/build-push-action@v2
    context: dockerfiles/syncthing
    platforms: linux/amd64
    build-args: |
    push: true
