Create Docker Images with Container-Extension

1. Create Docker Images with Container-Extension

1.1. Push Quarkus Image in a (Local) Registry

1.1.1. Create a Simple Quarkus Project with Jib

Source: Udemy Course: Quarkus Backend development with Java and GraalVM created by Dmytro Chaban

mvn io.quarkus:quarkus-maven-plugin:2.16.4.Final:create \
-DprojectGroupId=at.htl \
-DprojectArtifactId=containers \
-DclassName="at.htl.WeatherResource" \
-Dpath="/weather" \
-Dextensions="container-image-jib"

or add the extension to an existing project

./mvnw quarkus:add-extension -Dextensions="container-image-jib"

1.1.2. Start a Docker Container with a Docker Registry

We use this Image

docker run -d -p 5000:5000 --restart always --name registry registry:2

check, if the container is running

docker ps

terminal output

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
ee0da556eced        registry:2          "/entrypoint.sh /etc…"   19 seconds ago      Up 18 seconds       0.0.0.0:5000->5000/tcp   registry

1.1.3. Build the Quarkus Project as Image

./mvnw clean package -Dquarkus.container-image.build=true

1.1.4. Configure the Quarkus Project

src/main/resources/application.properties

quarkus.container-image.registry=localhost:5000
quarkus.container-image.insecure=true

docker images

terminal output

REPOSITORY           TAG                 IMAGE ID            CREATED             SIZE
stuetz/containers    1.0-SNAPSHOT        df644dfa092e        5 minutes ago       199MB
...

1.1.5. Push the Quarkus Project Image into the Registry

./mvnw clean package -Dquarkus.container-image.push=true

Alternative to jib (do not use)

#docker tag 22c42a7b1261 localhost:5000/containers
docker tag stuetz/containers:1.0-SNAPSHOT localhost:5000/containers
docker push localhost:5000/containers

Webpage

http://localhost:5000/v2/_catalog

k8s registry catalog

1.2. Change to Docker-Plugin from Jib-Plugin

pom.xml

...
<version>1.0.1-SNAPSHOT</version>
...
<dependency>
  <groupId>io.quarkus</groupId>
  <artifactId>quarkus-container-image-docker</artifactId> (1)
</dependency>
...

1	replace `quarkus-container-image-jib` with `quarkus-container-image-docker`

It’s also working, like with Jib

./mvnw clean package -Dquarkus.container-image.build=true
./mvnw clean package -Dquarkus.container-image.push=true
