alpine-appengine-java

AppEngine Java Docker Images built on Google CloudSDK Alpine Linux

Usage

Start using your devserver: docker run --rm -it -h localhost -v ~/.m2:/root/.m2 -v $(pwd):/usr/src/app -w /usr/src/app -p 8080:8080 zenika/alpine-appengine-java

Default command

mvn -Dapp.devserver.host="0.0.0.0" appengine:run

The parameter app.devserver.host to 0.0.0.0 allow us to ping our devserver from the container. It's an equivalent to <host>0.0.0.0</host> in the configuration section of our beloved pom.xml

Deploy commands

Start a bash using docker run --rm -it -h localhost -v ~/.m2:/root/.m2 -v $(pwd):/usr/src/app -v ~/.config/gcloud:/root/.config/gcloud -w /usr/src/app -p 8080:8080 zenika/alpine-appengine-java bash

We mount .config/gcloud to save the credentials.

Then use the following command:

gcloud auth login
#copy paste the url in your browser and then paste the token in your bash
gcloud config set project imt-2017-11
gcloud config set app/promote_by_default false
mvn -Dapp.deploy.version=v0 appengine:deploy

After this first deployment, you can simply launch another deployment using: docker run --rm -it -h localhost -v ~/.m2:/root/.m2 -v $(pwd):/usr/src/app -v ~/.config/gcloud:/root/.config/gcloud -w /usr/src/app -p 8080:8080 zenika/alpine-appengine-java mvn -Dapp.deploy.version=v1 appengine:deploy

Deploy index

Use the following command deployIndex:

docker run --rm -it -h localhost -v ~/.m2:/root/.m2 -v $(pwd):/usr/src/app -v ~/.config/gcloud:/root/.config/gcloud -w /usr/src/app -p 8080:8080 zenika/alpine-appengine-java mvn -Dapp.deploy.version=v1 appengine:deployIndex

Deploy queue

Use the following command deployQueue:

docker run --rm -it -h localhost -v ~/.m2:/root/.m2 -v $(pwd):/usr/src/app -v ~/.config/gcloud:/root/.config/gcloud -w /usr/src/app -p 8080:8080 zenika/alpine-appengine-java mvn -Dapp.deploy.version=v1 appengine:deployQueue
