jib plugin

Giriş

Bu bir Google plugin'i. Açıklaması şöyle. Dockerfile yazmaya gerek kalmadan image oluşturmaya yarar.

Jib is a Maven plugin and a Gradle plugin for building container images for your Java applications. It allows you to build container images directly from your Java code, without needing to manually create a Dockerfile. Jib handles all the steps of packaging your application into a container image, including building the application code, adding files to the image, and configuring the image to run the application.

Açıklaması şöyle. Image'ı local docker'a yükler.

Jib builds optimized Docker OCI images for Java applications. It is an open source project developed by Google. Similar to builldpacks, no Dockerfile needs to be created.

To use Jib, you need to add a maven plugin into your pom.xml file as follows:

<plugin>

    <groupId>com.google.cloud.tools</groupId>

    <artifactId>jib-maven-plugin</artifactId>

    <version>2.6.0</version>

</plugin>

To build the Docker image run the command:

./mvnw compile jib:dockerBuild -Dimage=rest-server-jib:0.0.1

Command to run the image:

docker run -it -p8080:8080 rest-server-jib:0.0.1

mvn clean install jib:dockerBuild -Djib.to.image=spring-docker-demo:v1

Şöyle yaparız. dockerBuild goal'ün package aşamasında altına yani yerel Docker'a iki tane image push'lar. Birisi belirtilen image tag'ini kullanır diğeri de latest tag'ini kullanır

mvn clean install jib:dockerBuild -P jib-push-to-local -Dapp.image.tag=v2

3. build Goal

Image'ı remote repository'ye yükler
