docker pull dreamcaster/spring-boot-demo-cmdline:Vanilla
docker run dreamcaster/spring-boot-demo-cmdline:Vanilla
mvn.cmd clean package
This Maven target will create a binary assembly ZIP at src/docker/assets/dist.
Configuration for the assembly is found at src/assembly/cli-assembly.xml
Binary assembly ZIP may also include assets placed under src/main/resources: sample files, folder structures, and execution scripts.
The start.class is defined at pom.xml
<properties>
...
<start.class>br.net.neuromancer.cmdline.vanilla.EntryPoint</start.class>
</properties>
An executable uber-JAR demo-cmdline.jar is created at the target folder.
The uber-JAR contains all dependencies, which is usually a good choice for a distribution.
As usual for Spring-Boot, the MOTD may be configured on src/resources/banner.txt
docker-compose -f app.yml up --build
To remove all exited containers
docker rm $(docker ps -a -f status=exited -q)
To remove all images
docker rm $(docker ps -a -f status=exited -q)
The main Dockerfile is placed under src/main/docker
Binary distributions is unzipped, ~/BIN_PACKAGE_PREFIX/bin/demo-cmdline.sh gets executed, then sleeps.
The sleep comes in handy for debugging: otherwise the container would only execute, exiting immediately
While sleeping, you may inspect the container:
$ docker ps -a
$docker exec -it demo_cmdline bin/sh
bash ./updateGitHubPages.sh
Sourced from the project README.MD of on branch gh-pages
Update on master, then replace the gh-branch
$ git push origin --delete gh-pages
$ git branch -D gh-pages
$ git init
$ git branch gh-pages
$ git push origin gh-pages
$ git branch
