Kafka Docker Images for other CPU architectures
08.02.2022, Michael Gerber

Many Docker images are unfortunately not yet available for the ARM64 CPUs such as the new Apple M1 processor. Kafka Docker images belong to these. However, they are necessary to have a local Kafka instance that is fast. This blog post describes how to build the Kafka images on your own for your own CPU.

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. Change the property ubi.openssl.version in the pom.xml to the latest 1.1.1k version (check the website for the latest version, 1.1.1k-5.el8_5 at the time of writing)
  5. Change the property ubi.zulu.openjdk.version in the pom.xml to 11.0.14.1 (check the website for the latest version)
  6. Run the following command to build the base image:
    mvn clean install \
      -DskipTests -Pdocker \
      -Ddocker.registry=nxt/
    

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
