Using external action output in outer git action step - github

Question

I have this git action for my build
...
- name: Building S3 Instance
uses: charlie87041/s3-actions#main
id: s3
env:
AWS_S3_BUCKET: 'xxx'
AWS_ACCESS_KEY_ID: 'xxx'
AWS_SECRET_ACCESS_KEY: 'xxxxx'
AWS_REGION: 'xxx'
- name: Updating EC2 [Develop] instance
uses: appleboy/ssh-action#master
with:
host: ${{secrets.EC2HOST}}
key: ${{secrets.EC2KEY}}
username: xxx
envs: TESTING
script: |
cd ~/devdir
export BUCKET_USER=${{steps.s3.outputs.user_id}}
export BUCKET_USER_KEY=${{steps.s3.outputs.user_key}}
docker login
docker-compose down --remove-orphans
docker system prune -a -f
docker pull yyyy
docker-compose up -d
And this is the important function in charlie87041/s3-actions#main
generate_keys () {
RSP=$(aws iam create-access-key --user-name $USER);
BUCKET_ACCESS_ID=$(echo $RSP | jq -r '.AccessKey.AccessKeyId');
BUCKET_ACCESS_KEY=$(echo $RSP | jq -r '.AccessKey.SecretAccessKey');
echo "user_id=$BUCKET_ACCESS_ID" >> $GITHUB_OUTPUT
echo "user_key=$BUCKET_ACCESS_KEY" >> $GITHUB_OUTPUT
echo "::set-output name=BUCKET_ACCESS_KEY::$BUCKET_ACCESS_KEY"
echo "::set-output name=BUCKET_ACCESS_ID::$BUCKET_ACCESS_ID"
}
I need to update env variables in container with BUCKET_USER and BUCKET_USER_KEY, but these always return null when echo the container. How do I do this?

Not that set-output was deprecated recently (oct. 2022)
If you are using self-hosted runners make sure they are updated to version 2.297.0 or greater.
If you are using runner on github.com directly, you would need to change
echo "::set-output name=BUCKET_ACCESS_KEY::$BUCKET_ACCESS_KEY"
with
echo "BUCKET_ACCESS_KEY=$BUCKET_ACCESS_KEY" >> $GITHUB_OUTPUT
I am not sure an export within the script would work.
Using with directives, as in issue 154 might be more effective
with:
BUCKET_USER: ${{steps.s3.outputs.user_id}}
...
script: |
