dockerbuild

Multiplatform Docker build support scripts

The build-push-images.sh script is meant to build Java and optionally native images. Usage is not restricted to (or specialized for) :nessie-quarkus, but can be used with basically any Quarkus application.

Minimal options (use ./build-push-images.sh --help for an up-to-date listing) are:

• --gradle-project <gradle-project-name> in the :my-project-name syntax
• --project-dir <gradle-project-directory> like servers/quarkus-server
• the image name as an argument, for example projectnessie/nessie

The image name also defines where the built images are pushed to. By (Docker) default, it's Docker Hub.

Push to a local Docker registry (localhost:5000)

To push to a locally running Docker registry, prefix the image name with localhost:5000/. For example (see local Docker registry notes below):

tools/dockerbuild/build-push-images.sh \
  --gradle-project :nessie-quarkus \
  --project-dir servers/quarkus-server \
  localhost:5000/projectnessie/nessie-local

Hint: The images are pushed to the local registry, those will not show up in docker images.

Build an image for local use

tools/dockerbuild/build-push-images.sh \
  --gradle-project :nessie-quarkus \
  --project-dir servers/quarkus-server \
  --local \
  localhost/projectnessie/nessie-local

Updating your local Docker registry

There's a docker-registry Debian/Ubuntu package. The registry configuration might need some tweaks like this. You can also use the official Docker registry.

• http.addr may default to ::1, which is TCP6, and the Docker tools might not be able to connect to it. Change http.addr to 127.0.0.1:5000.
• Change auth.htpasswd.path to /etc/docker/registry/htpasswd
• Create the htpasswd file - for example: htpasswd -B $(id -un), if /etc/docker/registry/htpasswd doesn't yet exist, add the -c option.
• Login to your local registry using docker login -u $(id -un) localhost:5000
