This project is a simple spring-boot application running an embedded jetty server on port 8080.
The project is managed by maven so building is achieved by running:
mvn package
The application can be run by using its jar file:
java -jar booter-<version>.jar
If you need to run the server on a different port than 8080 that can be done by specifying the server.port system property:
java -Dserver.port=9000 -jar booter-<version>.jar
This project provides configuration files for running this application
inside a Docker container. A production-ready image can be built
using the supplied Dockerfile:
docker build -t booter:latest .
The above command will build the container image, name it booter and tag it with the tag latest.
Development and testing of the docker image can be achieved by using
Docker Compose. The supplied docker-compose.yml file provides definitions
for building and running a Docker container and exposing its port, 8080,
to port 80 on the localhost.
The default Dockerfile builds the application using maven inside the
container. This can be a lengthy process. To speed up development the
docker-compose.yml includes instructions to mount a volume from the
maven build directory, ./target, to the docker image such that
the application can be rebuilt directly using maven without having to
rebuild the entire docker image.
The following environment variables are defined and used in the Docker image:
- APPDIR - Absolute path to the directory where the application files reside.
- APPNAME - Name of the application jar file.
