Payara server comes with disabled autodeployment feature, what makes deployments at start in containerized environments, like Docker or clouds, more challenging.

Fortunately, Payara Server 172 introduced the --postbootcommandfile flag.

asadmin commands like e.g. deploy can be read from a file specified with the postbootcommandfile flag and executed after successful Payara's start, e.g.: asadmin start-domain --verbose --postbootcommandfile commands.txt. The postbootcommandfile feature makes deployments at boottime even more predictable.

All Payara-related docklands Dockerfiles are using the "postbootcommandfile" feature already. Also the hub.docker.com/u/airhacks/ airhacks/payara and airhacks/payara-derby were updated.

To start a Thin WAR (=kB) microservice, you only have to write these two lines in a Dockerfile:

        
        FROM airhacks/payara
        COPY ./target/micro.war ${DEPLOYMENT_DIR}
