Container Image extensions

Jib

The extension quarkus-container-image-jib is powered by Jib for performing container image builds. The major benefit of using Jib with Quarkus is that all the dependencies (everything found under target/lib) are cached in a different layer than the actual application making rebuilds really fast and small (when it comes to pushing). Another important benefit of using this extension is that it provides the ability to create a container image without having to have any dedicated client side tooling (like Docker) or running daemon processes (like the Docker daemon) when all that is needed is the ability to push to a container image registry.

To use this feature, add the following extension to your project:

CLI

quarkus extension add 'container-image-jib'

Maven

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

Gradle

./gradlew addExtension --extensions="container-image-jib"

In situations where all that is needed to build a container image and no push to a registry is necessary (essentially by having set quarkus.container-image.build=true and left quarkus.container-image.push unset - it defaults to false), then this extension creates a container image and registers it with the Docker daemon. This means that although Docker isn’t used to build the image, it is nevertheless necessary. Also note that using this mode, the built container image will show up when executing docker images.

Including extra files

There are cases when additional files (other than ones produced by the Quarkus build) need to be added to a container image. To support these cases, Quarkus copies any file under src/main/jib into the built container image (which is essentially the same idea that the Jib Maven and Gradle plugins support). For example, the presence of src/main/jib/foo/bar would result in /foo/bar being added into the container filesystem.

JVM Debugging

There are cases where the built container image may need to have Java debugging conditionally enabled at runtime.

When the base image has not been changed (and therefore ubi8/openjdk-11-runtime or ubi8/openjdk-17-runtime is used), then the quarkus.jib.jvm-arguments configuration property can be used in order to make the JVM listen on the debug port at startup.

The exact configuration is:

quarkus.jib.jvm-arguments=-agentlib:jdwp=transport=dt_socket\\,server=y\\,suspend=n\\,address=*:5005

Other base images might provide launch scripts that enable debugging when an environment variable is set, in which case you would set than environment variable when launching the container.

Custom Entrypoint

The quarkus.jib.jvm-entrypoint configuration property can be used to completely override the container entry point and can thus be used to either hard code the JVM debug configuration or point to a script that handles the details.

For example, if the base images ubi8/openjdk-11-runtime or ubi8/openjdk-17-runtime are used to build the container, the entry point can be hard-coded on the application properties file.

Example application.properties

quarkus.jib.jvm-entrypoint=java,-Dcustom.param=custom_value,-jar,quarkus-run.jar

Or a custom start-up script can be created and referenced on the properties file. This approach works better if there’s a need to set application params using environment variables:

Example application.properties

quarkus.jib.jvm-entrypoint=/bin/sh,run-java.sh

Example src/main/jib/home/jboss/run-java.sh

java \
  -Djavax.net.ssl.trustStore=/deployments/truststore \
  -Djavax.net.ssl.trustStorePassword="$TRUST_STORE_PASSWORD" \
  -jar quarkus-run.jar

/home/jboss is the WORKDIR for all quarkus binaries in the base images ubi8/openjdk-11-runtime and ubi8/openjdk-17-runtime (Dockerfile for ubi8/openjdk-17-runtime)

Multi-module projects and layering

When building a multi-module project containing a Quarkus application as one module and various supporting project dependencies as other modules, Quarkus supports placing these supporting modules in a separate container image layer from the rest of the application dependencies, with the expectation that these supporting modules will change more frequently than the regular application dependencies - thus making a rebuild faster if the application dependencies have not changed.

To enable this feature, the property quarkus.bootstrap.workspace-discovery needs to be set to true either as a system property when invoking the build tool, either as a build tool property. Setting this property in application.properties will not work because this property needs to be known very early on in the build process.

Docker

The extension quarkus-container-image-docker is using the Docker binary and the generated Dockerfiles under src/main/docker in order to perform Docker builds.

To use this feature, add the following extension to your project.

CLI

quarkus extension add 'container-image-docker'

Maven

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

Gradle

./gradlew addExtension --extensions="container-image-docker"

The quarkus-container-image-docker extension is capable of creating multi-platform (or multi-arch) images using docker buildx build. See the quarkus.docker.buildx.* configuration items in the Docker Options section below.

docker buildx build ONLY supports loading the result of a build to docker images when building for a single platform. Therefore, if you specify more than one argument in the quarkus.docker.buildx.platform property, the resulting images will not be loaded into docker images. If quarkus.docker.buildx.platform is omitted or if only a single platform is specified, it will then be loaded into docker images.

S2I

The extension quarkus-container-image-s2i is using S2I binary builds in order to perform container builds inside the OpenShift cluster. The idea behind the binary build is that you just upload the artifact and its dependencies to the cluster and during the build they will be merged to a builder image (defaults to fabric8/s2i-java).

The benefit of this approach, is that it can be combined with OpenShift’s DeploymentConfig that makes it easy to roll out changes to the cluster.

To use this feature, add the following extension to your project.

CLI

quarkus extension add 'container-image-s2i'

Maven

./mvnw quarkus:add-extension -Dextensions="container-image-s2i"

Gradle

./gradlew addExtension --extensions="container-image-s2i"

S2I builds require creating a BuildConfig and two ImageStream resources, one for the builder image and one for the output image. The creation of such objects is being taken care of by the Quarkus Kubernetes extension.

Buildpack

The extension quarkus-container-image-buildpack is using buildpacks in order to perform container image builds. Under the hood buildpacks will use a Docker daemon for the actual build. While buildpacks support alternatives to Docker, this extension will only work with Docker.

Additionally, the user will have to configure which build image to use (no default image is provided). For example:

quarkus.buildpack.jvm-builder-image=<jvm builder image>

or for native:

quarkus.buildpack.native-builder-image=<native builder image>

To use this feature, add the following extension to your project.

CLI

quarkus extension add 'container-image-buildpack'

Maven

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

Gradle

./gradlew addExtension --extensions="container-image-buildpack"

When using the buildpack container image extension it is strongly advised to avoid adding quarkus.container-image.build=true in your properties configuration as it might trigger nesting builds within builds. It’s preferable to pass it as an option to the build command instead.

Building

To build a container image for your project, quarkus.container-image.build=true needs to be set using any of the ways that Quarkus supports.

CLI

quarkus build -Dquarkus.container-image.build=true

Maven

./mvnw install -Dquarkus.container-image.build=true

Gradle

./gradlew build -Dquarkus.container-image.build=true

If you ever want to build a native container image and already have an existing native image you can set -Dquarkus.native.reuse-existing=true and the native image build will not be re-run.

Using @QuarkusIntegrationTest

To run tests on the resulting image, quarkus.container-image.build=true needs to be set using any of the ways that Quarkus supports.

Maven

./mvnw verify -Dquarkus.container-image.build=true

Gradle

./gradlew quarkusIntTest -Dquarkus.container-image.build=true

Pushing

To push a container image for your project, quarkus.container-image.push=true needs to be set using any of the ways that Quarkus supports.

CLI

quarkus build -Dquarkus.container-image.push=true

Maven

./mvnw install -Dquarkus.container-image.push=true

Gradle

./gradlew build -Dquarkus.container-image.push=true

If no registry is set (using quarkus.container-image.registry) then docker.io will be used as the default.

Selecting among multiple extensions

It does not make sense to use multiple extension as part of the same build. When multiple container image extensions are present, an error will be raised to inform the user. The user can either remove the unneeded extensions or select one using application.properties.

For example, if both container-image-docker and container-image-s2i are present and the user needs to use container-image-docker:

quarkus.container-image.builder=docker

Customizing

The following properties can be used to customize the container image build process.

Using CI Environments

Various CI environments provide a ready to use container-image registry which can be combined with the container-image Quarkus extensions in order to effortlessly create and push a Quarkus application to said registry.

For example, GitLab provides such a registry and in the provided CI environment, makes available the CI_REGISTRY_IMAGE environment variable (see GitLab’s documentation) for more information), which can be used in Quarkus like so:

quarkus.container-image.image=${CI_REGISTRY_IMAGE}

See this for more information on how to combine properties with environment variables.

Jib Options

In addition to the generic container image options, the container-image-jib also provides the following options:

Configuration property fixed at build time - All other configuration properties are overridable at runtime

When the application is built against Java 17 or higher, `registry.access.redhat.com/ubi8/openjdk-17-runtime:1.11` is used as the default. Otherwise `registry.access.redhat.com/ubi8/openjdk-11-runtime:1.11` is used as the default. Environment variable: `QUARKUS_JIB_BASE_JVM_IMAGE`	string
`quarkus.jib.base-native-image` The base image to be used when a container image is being produced for the native binary build. The default is "quay.io/quarkus/quarkus-micro-image". You can also use "registry.access.redhat.com/ubi8/ubi-minimal" which is a bigger base image, but provide more built-in utilities such as the microdnf package manager.

To that end it’s helpful to remember that when `fast-jar` packaging is used (the default), all necessary application jars are added to the `/work` directory and that the same directory is also used as the working directory. When `legacy-jar` or `uber-jar` are used, the application jars are unpacked under the `/app` directory and that directory is used as the working directory. - Even if the `jvmArguments` field is set, it is ignored completely When this is not set, a proper default entrypoint will be constructed.

Each platform is defined using the pattern: `<os>\|<arch>[/variant]\|<os>/<arch>[/variant]` for example: `linux/amd64,linux/arm64/v8` If not specified, OS default is linux and architecture default is `amd64`. If more than one platform is configured, it is important to note that the base image has to be a Docker manifest or an OCI image index containing a version of each chosen platform. The feature does not work with native images, as cross-compilation is not supported. This configuration is based on an incubating feature of Jib. See Jib FAQ for more information. Environment variable: `QUARKUS_JIB_PLATFORMS`	list of string
`quarkus.jib.image-digest-file` The path of a file in which the digest of the generated image will be written. If the path is relative, the base path is the output directory of the build tool. Environment variable: `QUARKUS_JIB_IMAGE_DIGEST_FILE`	string	`jib-image.digest`

Otherwise, the modification time will be set to the Unix epoch (00:00:00, January 1st, 1970 in UTC). If the modification time is constant (flag is set to false so Unix epoch is used) across two consecutive builds, the docker layer sha256 digest will be different only if the actual files added by Jib to the docker layer were changed. More exactly, having 2 consecutive builds will generate different docker layers only if the actual content of the files within the docker layer was changed. If the current timestamp is used the sha256 digest of the docker layer will always be different even if the content of the files didn’t change.

About the Duration format

The format for durations uses the standard java.time.Duration format. You can learn more about it in the Duration#parse() javadoc.

You can also provide duration values starting with a number. In this case, if the value consists only of a number, the converter treats the value as seconds. Otherwise, PT is implicitly prepended to the value to obtain a standard java.time.Duration format.
