Enabling gzip in an appengine-flex service

[Vinay Chitlangia]

I am trying to enable gzip in our appengine-flex service.

I followed the instructions in https://cloud.google.com/appengine/docs/flexible/java/dev-jetty9

The app.yaml has the following addition

env_variables:

JETTY_MODULES_ENABLE: 'gzip'

However for requests that we make using URLConnection from another appengine module (standard appengine), the responses are

not zipped. AFAICT the responses made from chrome are not zipped either.

The responses from our service are "text/plain".

We are using a custom runtime running java and jetty9. Here is the dockerfile.

Thanks for your help.

FROM gcr.io/google-appengine/jetty9

RUN apt-get -q update && \

    apt-get -y -q --no-install-recommends -t jessie-backports install openjdk-8-jdk && \

    apt-get -y -q --no-install-recommends install ssh sshpass netcat && \

    apt-get clean && \

    rm /var/lib/apt/lists/*_*

ADD backend.war $JETTY_BASE/webapps/root.war

WORKDIR $JETTY_BASE

RUN java -jar $JETTY_HOME/start.jar --approve-all-licenses \

 --add-to-startd=jmx,stats,hawtio,requestlog \

 -Djava.util.logging.config.file=src/main/appengine/logging.properties \

 && chown -R jetty:jetty $JETTY_BASE
