Docker Common

A collection of Docker images for development and operational environments. These images are designed to provide consistent and reliable environments for Java development, database operations, and tunneling services.

To build any image locally:

cd <image-directory>
docker build -t <name>:<tag> .

For Maven and MVND images that use version arguments:

docker build --build-arg MAVEN_VERSION=3.9.9 -t maven:custom .
