Apache NIFI The request contained an invalid host header

I am trying to run Apache NIFI on a docker in my Rancher server. Rancher is running correclty as I have other services running. It is installed on a Debian box.

I am trying to test the official Apache Nifi container. As rancher's default port is 8080, I am trying to run it on another port. I am trying to run the first command as it is referenced in the documentation:

docker run --name nifi -p 9090:9090 -d -e NIFI_WEB_HTTP_PORT='9090' apache/nifi:latest

This gives me the error I mentioned in the title:

The request contained an invalid host header [xx.xx.xx.xx:9090] in the request [/nifi]. Check for request manipulation or third-party intercept.

I have tried to run it on a ubuntu laptop where docker is freshly installed and it started without problems.

If I get to the docker command line with docker exec -it nifi bash I see that I have no vi, nano nor any way of editing the nifi configuration file where I am supposed to change that information.

I have tried to create it directly from the rancher interface but it stays for a very long time just starting the container.

What I am doing wrong?

Apache NiFi 1.6.0 was just released (April 8, 2018) and the Docker image should update within the next few days to refer to that version. In 1.6.0, the host header handling was relaxed to be more user-friendly:

  • NIFI-4761 Host headers are not blocked on unsecured instances (i.e. unless you have configured TLS, you won't see this message anymore)
  • NIFI-4761 A new property in nifi.properties (nifi.web.proxy.host) was added to allow for listing acceptable hostnames that are not the nifi.web.http(s).host
  • NIFI-4788 The Dockerfile was updated to allow for this acceptable listing via a parameter like NIFI_WEB_PROXY_HOST='someotherhost.com'

I'm not familiar with Rancher, but I would think the container would have some text editor installed.

Finally Rancher through the Web itnerface and after a LONG wait has managed to start the container and it works.

I still don't know why on the command line it is not working, but now it is secondary.
