Unable to deploy my code to google cloud app engine via gitlab

问题

I am trying to create a gitlab pipeline for deploying my spring boot app to google app engine and i am able to authenticate app engine to gitlab but at deployment step of ci file i am getting Java 7+ JRE must be installed and on your system PATH though i have installed it with gcloud install components app-engine-java command in gitlab ci file. Please suggest what needs to be done to resolve this error.

.gitlab-ci.yml file:

image: google/cloud-sdk:alpine

            deploy_production:
              stage: deploy
              environment: Production
              only:
              - master
              script:
              - echo $DEPLOY_KEY_FILE_PRODUCTION > /tmp/$CI_PIPELINE_ID.json
              - gcloud -q components install app-engine-java
              - gcloud auth activate-service-account --key-file /tmp/$CI_PIPELINE_ID.json
              - gcloud --quiet --project $PROJECT_ID_PRODUCTION --verbosity debug app deploy src/main/webapp/WEB-INF/appengine-web.xml

Below are the debug details which mentions that to use the local staging for java, java JRE must be installed though i have installed it using gcloud install components google-app-engine cmd:

$ gcloud --quiet --project $PROJECT_ID_PRODUCTION --verbosity debug app deploy src/main/webapp/WEB-INF/appengine-web.xml

Some people got the same issue trying to create the same workflow, but with github. The same issue can be viewed here. This guy solved this by adding openjdk-8 to Docker.

You can see here how to add openjdk-8 to Docker.

If this did not work for you, please let me know and I will try to edit my answer.

You may also want to check Jenkins for Google Cloud and using Jenkins with Gitlab for CI. It may be helpful for your CI workflow.
