Docker Image Quickstart

Building

The Docker image can be built using the following command:

docker build -t apache/nifi-minifi:latest .

This build will result in an image tagged apache/nifi:latest

$ docker images
REPOSITORY               TAG                 IMAGE ID            CREATED                 SIZE
apache/nifi-minifi              latest              f0f564eed149        A long, long time ago   226MB

Note: The default version of NiFi specified by the Dockerfile is typically that of one that is unreleased if working from source. To build an image for a prior released version, one can override the MINIFI_VERSION build-arg with the following command:

docker build --build-arg=MINIFI_VERSION={Desired MiNiFi Version} -t apache/nifi-minifi:latest .

Running a container

Supplying configuration to a container

The primary means by which a MiNiFi instance is configured is via the flow.json.raw or the bootstrap.conf.

This can be accomplished through:

• the use of volumes, and
• overlaying the base image

Using volumes to provide configuration

The following example shows the usage of two volumes to provide both a flow.json.raw and a bootstrap.conf to the container instance. This makes use of configuration files on the host and maps them to be used by the MiNiFi instance. This is helpful in scenarios where a single image is used for a variety of configurations.

docker run -d \
    -v ~/minifi-conf/flow.json.raw:/opt/minifi/minifi-current/conf/flow.json.raw \
    -v ~/minifi-conf/bootstrap.conf:/opt/minifi/minifi-current/conf/bootstrap.conf \
    apache/nifi-minifi:latest

Using volumes to provide configuration

Alternatively, it is possible to create a custom image inheriting from the published image. Creating a Dockerfile extending from the Apache NiFi MiNiFi base image allows users to overlay the configuration permanently into a newly built and custom image. A simple example follows:

FROM apache/nifi-minifi

ADD flow.json.raw /opt/minifi/minifi-current/conf/flow.json.raw
ADD bootstrap.conf /opt/minifi/minifi-current/conf/bootstrap.conf

Building this Dockerfile will result in a custom image with the specified configuration files incorporated into the new image. This is best for applications where configuration is well defined and relatively static.
