@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, André   ...
