Running Apache Nifi on Docker without 0.0.0.0

[#1]

After configuring my Dockerfile with:

ENV NIFI_WEB_HTTPS_HOST=0.0.0.0

ENV NIFI_WEB_HTTPS_PORT=8443

I was able to run the container and access UI.

If I increase replica, my cluster informations registries two address nodes 0.0.0.0:8443 and any changes I try to make I receive the error:

Node 0.0.0.0:8443 is unable to fulfill this request due to: Transaction 00671bfc-20b8-4257-8590-8936e7265fde is already in progress.

If I remove NIFI_WEB_HTTPS_HOST property, I cannot access UI, but log say that Jetty is running with container name, not 0.0.0.0.

Is it possible to run nifi in a container without 0.0.0.0?

@samaan_filho ,

You can have 2 docker containers running NiFi, each one using the same local port 8443. You cannot expose both of those ports with the same port number to your local machine, though. You'd have to map to different port numbers when exposing them. Can you share more details?

Alternatively, please take a look at this article: https://community.cloudera.com/t5/Community-Articles/NiFi-cluster-sandbox-on-Docker/ta-p/346271

Cheers,
