[Deployment Issue] Unable to access all ports of a container

[skiv71]

I have an IPFS docker container which exposes 4001, 5001 & 8080.

If I run the container on my local machine using docker, it all works ok... but in caprover, there appears to be an issue, where only 4001 is accessible.

With regards to connection, I'm only talking about within the caprover network (i.e. srv-captain--)

I've seen this issue #853 and I'm not sure I'm struggling with something similar?

I used caprover a few years ago and never had this issue.

I've tried running a terminal in another container to check the local docker network connectivity and this fails for anything but 4001

I've done some debugging and this is what I've found: -

docker service ps srv-captain--ipfs

A common problem is when your source is only binding to a specific IP address. Connections work if they are set up like this: 0.0.0.0:5001
