docker - cant listen on localhost

[awcoding]

can't get checkr/flagr working with -p 127.0.0.1:18000:18000.
I tried it with both -e HOST=0.0.0.0 and -e "HOST=127.0.0.1". No joy.

am i missing something? I tried to workaround but firewall on this box is hellishy complicated and that option appears less accessible.

I got it working here with:

docker run -p 18000:18000 checkr/flagr

I don't believe you need to put the host before the port.

Thank you @marceloboeira. My goal is to listen on the localhost interface instead of all interfaces. Prefixing the 127.0.0.1 is docker's convention on how to do that. But it doesn't seem to be working for this case.

Interesting, I've never had a usecase for that. I've tried here:

docker run -p 127.0.0.1:18000:18000 checkr/flagr
docker run -p 0.0.0.0:18000:18000 checkr/flagr

both worked, no HOST/ENV

Yeah, it worked for me too just now. I don't know how but I must have screwed something up earlier. Closing issue.

For interest this is almost certainly where I screwed up earlier:
ssh -L 18000:127.0.0.1:18000 root@example.org
NOT
ssh -L 18000:example.org:18000 root@example.org
