I am calling a GitHub action, and I want to pass it the parameter extra_build_args with the value --build-arg CURRENT_DD_VERSION={$VER} (not in string) where $VER is a shell variable that I set with a specific version. When I check what was passed in I see it took the literal value {$VER} instead of resolving the variable. I set $VER in a different (earlier) step of the Github action. How can pass in the content of the shell variable as a parameter?
- name: Get version
run: |
VER=$(cat ver.txt)
- name: Build docker image
uses: kciter/aws-ecr-action@v3
with:
//some more parameters
extra_build_args: "--build-arg CURRENT_DD_VERSION={$VER}"
Check first the syntax:
${VER}
# not
{$VER}
In your case:
extra_build_args: "--build-arg CURRENT_DD_VERSION=${VER}"
You also have the documentation "Environment variables"
To set custom environment variables, you need to specify the variables in the workflow file.
You can define environment variables for a step, job, or entire workflow using thejobs.<job_id>.steps[*].env,jobs.<job_id>.env, andenvkeywords.
The examples would use $VER
Or:
extra_build_args: "--build-arg CURRENT_DD_VERSION=${{ env.VER }}"
