The official documentation can be found here.

Is there a way to combine two Docker base images in a single container and build with kaniko?

The use case is such that I need both JDK and Mongo images in a single container, the java process starts up the Mongo daemon process.

    You are not needed to use two base images. just use one of the base image jdk/mongo and then using binaries install mongo/jdk on top of the chosen base image.

    Here’s the minimum Dockerfile that bake JRE 11 to the mongo image.

    FROM mongo:latest

# Replace the version if desired
RUN apt-get update -y && apt-get install openjdk-11-jre-headless -y

# Install your app and stuffs here...

# Override for your own command
CMD ["java","-version"]

    Build the image docker build -t mongodb-java .

    Test the image docker run -t --rm mongodb-java will output the JRE version.

    Test the image docker run -t --rm mongodb-java mongo --version will output the MongoDB version.

    You can then follow Kaniko steps to build the image.
