proxy-nifi-docker

An example of several proxies in front of Apache NiFi, all running in docker containers.

Build the NiFi dockermaven image

From the clone of the Apache NiFi repository, on the appropriate branch:

1. mvn clean install -Pcontrib-check
2. mvn install -pl nifi-docker/dockermaven/pom.xml -Pdocker
3. docker images
   Confirm the NiFi 1.9.0-SNAPSHOT docker image exists:

   $ docker images
   REPOSITORY             TAG                          IMAGE ID            CREATED             SIZE
   apache/nifi            1.9.0-SNAPSHOT-dockermaven   119e30c23439        5 minutes ago       1.82GB
   

Starting the containers

• ./scripts/start.sh

Watching the logs

• docker-compose -f knox-dev-docker/docker-compose.yml logs -f
• docker-compose -f docker-compose-anonymous-nifi.yaml logs -f

Accessing NiFi

• NiFi is available
  • on the host at: http://localhost:9090/nifi/
  • through Traefik at: http://nifi.docker.localhost/traefik/nifi/
  • through Knox at: https://localhost:8443/gateway/nifi/nifi-app/nifi/
  • through Nginx at: http://nginx.docker.localhost:8081/nifi/

Verifying proxy functionality

1. Go to url: http://nifi.docker.localhost/traefik/nifi/
   Traefik uses X-Forwarded-Host/X-Forwarded-Prefix:
   1. Add several processors and connect them
   2. Verify that the processors can be moved on the canvas
   3. Open the processor configuration for any of the processors
   4. View Usage for any of the processors on the canvas
2. Go to url: https://localhost:8443/gateway/nifi/nifi-app/nifi
   Knox uses X-Forwarded-Host/X-Forwarded-Context:
   1. Add several processors and connect them
   2. Verify that the processors can be moved on the canvas
   3. Open the processor configuration for any of the processors
   4. View Usage for any of the processors on the canvas
3. Go to url: http://nginx.docker.localhost:8081/nifi/
   Nginx is configured to use X-ProxyHost/X-ProxyContextPath:
   1. Add several processors and connect them
   2. Verify that the processors can be moved on the canvas
   3. Open the processor configuration for any of the processors
   4. View Usage for any of the processors on the canvas

Stopping the containers

• ./scripts/stop.sh
