After running the flow, I can find

问题 For the life of me I can't get to the NiFi Web UI. It makes me hate security. TLDR; I can't find the right way to start NiFi in a docker container and still access the UI. Here's what I've tried (for 8 hours): docker run --name nifi \ -p 8080:8080 \ -d \ apache/nifi:latest I go to localhost:8080/nifi - timeout. Same on 127.0.0.1 . docker inspect nifi - IP Gateway is 172.20.0.1 with actual IP of 172.0.0.2 . Invalid Host Header and timeout, respectively. Start randomly trying stuff: # I tried
