Extending a PACC
You can use a PACC to create a new Docker image.

While you cannot modify a data-fabric Docker image directly, you can build a custom image that is based on a Persistent Application Client Container (PACC). The following example shows a custom Dockerfile that is used to create a new Docker image. In this example, an application has a JAR file that takes a producer as a parameter and runs a custom function.
The example has two parts. In Part 1, the custom Dockerfile uses the Docker
FROM
command to download a PACC to a
container on the user platform. A directory is created, and a JAR file is copied into the
container so that it can be run in Java. The CMD
command starts the
application inside the container. In Part 2, the custom Dockerfile is built using the
docker build
command.
Part 1. Creating a Custom Dockerfile
FROM maprtech/pacc:5.2.0_2.0_centos6
# Copy jar to container
RUN mkdir -p /usr/share/mapr-apps/
COPY mapr-streams-examples-1.0-SNAPSHOT-jar-with-dependencies.jar /usr/share/mapr-apps/mapr-app-001.jar
# Run producer application in container
CMD [ "java", "-cp", "$MAPR_CLASSPATH:/usr/share/mapr-apps/mapr-app-001.jar", "com.mapr.examples.Run", "producer" ]
Part 2. Building a Custom Docker Image From the Dockerfile
docker build -t <new docker image> .
Note: Above needs to be run in the same directory as Dockerfile
Make sure the image is created and no issue building Docker image.
docker images -a
