App Engine deployment pipe fails to deploy Spring Boot app

mklosinski

I'm testing out Bitbucket Pipe for GCloud App Engine deployment. It turns out the deployment fails with the following message, stating that Java environment is missing:

INFO: Starting deployment to GCP app engine...
gcloud app deploy src/main/webapp/WEB-INF/appengine-web.xml --quiet
The component [app-engine-java] is required for staging this 
application.

Restarting command:
$ gcloud app deploy src/main/webapp/WEB-INF/appengine-web.xml --quiet
ERROR: (gcloud.app.deploy) To use the local staging for java, a Java 7+ JRE must be installed and on your system PATH
Deployment failed.

I manually examined the pipe Docker container and indeed it doesn't seem to have any Java installed:

docker run -i -t --entrypoint /bin/bash bitbucketpipelines/google-app-engine-deploy:0.3.1
bash-4.4# java -version
bash: java: command not found

I got around this, somewhat, by using atlassian/google-app-engine-deploy:0.3.0 (version 0.3.0 instead of 0.3.1). I looked at the sizes of the two versions on dockerhub and noticed a very large difference in size. Assumed that a JRE was missing and thought I'd have nothing to lose in trying the downgrade.

 

So I get messages that tell me the app has deployed successfully, however something is still not right with it, as when I go to use it I get a "404 Not Found" - and the stackdriver logs aren't really telling me much yet. But according to the appengine dashboard the correct version of application seems to be running and available.
