Kafka Docker Images for other CPU architectures

08.02.2022, Michael Gerber

Required Packages

The following packages are required to build the Kafka Docker images:

• socat
• docker
• java
• maven

Run Docker Builds from Maven

The Kafka Docker build is based on the Maven plugin dockerfile-maven-plugin. Unfortunately, at least on an M1 Mac, it did not work out of the box. Maven builds failed with the following error:

[ERROR] Failed to execute goal com.spotify:dockerfile-maven-plugin:1.4.13:build (package) on project cp-base-new: Could not build image: java.util.concurrent.ExecutionException: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: java.lang.UnsatisfiedLinkError: could not load FFI provider com.spotify.docker.client.shaded.jnr.ffi.provider.jffi.Provider: ExceptionInInitializerError: Can't overwrite cause with java.lang.UnsatisfiedLinkError: java.lang.UnsatisfiedLinkError: Can't load library: /var/folders/90/trptjc/T/jffi6971633642015255287.dylib

As a workaround, the Docker control socket can be exposed on the TCP port 2375. This can be achieved with socat:

socat TCP-LISTEN:2375,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock

Now update the environment variable DOCKER_HOST to point to tcp://127.0.0.1:2375:

export DOCKER_HOST=tcp://127.0.0.1:2375

Build the Base Image

1. Clone the common-docker git repository
2. Check out the desired version git checkout tags/v7.0.0
3. Open the pom.xml file from the root directory and add the confluent repository:

    <repositories>
        <repository>
            <id>confluent</id>
            <url>https://packages.confluent.io/maven/</url>
        </repository>
    </repositories>
   

4. Run the following command to see all available yum packages and versions:

   docker run --rm -ti confluentinc/cp-base-new yum list available
   

5. Change the property ubi.openssl.version in the pom.xml to the latest available version (check the website for the latest version)
6. Change the property ubi.zulu.openjdk.version in the pom.xml to the latest available version (check the website for the latest version)
7. Run the following command to build the base image:

   mvn clean install \
     -DskipTests -Pdocker \
     -Ddocker.registry=nxt/ -Ddocker.skip-test=true
   

Build Kafka and Zookeeper Images

1. Clone the kafka-images git repository
2. Check out the desired version git checkout tags/v7.0.0
3. Run the following command to build the Kafka and Zookeeper image:

   mvn clean package \
     -DskipTests -Pdocker \
     -DCONFLUENT_PACKAGES_REPO='https://packages.confluent.io/rpm/7.0' \
     -DCONFLUENT_VERSION=7.0.0 \
     -Ddocker.registry=nxt/
   

Build Schema Registry Image

1. Clone the schema-registry-images git repository
2. Check out the desired version git checkout tags/v7.0.0
3. Run the following command to build the Schema Registry image:

   mvn clean package \
     -DskipTests -Pdocker \
     -DCONFLUENT_PACKAGES_REPO='https://packages.confluent.io/rpm/7.0' \
     -DCONFLUENT_VERSION=7.0.0 \
     -Ddocker.registry=nxt/
   

Verify the new Images

Run docker images | grep confluentinc to list all images:

$ docker images | grep confluentinc
