The simple test is the same. Do you have any idea what is wrong?

Hi did you try to expose the ports? Can you try to use inspect command to see more information of docker instance?

[fchris82]

I do not have to expose them, I call it from another container, and it can see the fake API container. I am pretty sure about it.

Meantime, I looked for another fake API docker image, and I use that one because there is currently time pressure. But thank you for the answer, maybe it is only an unusual problem only at me.

@dotronglong I believe you shoudl reopen this issue. We have the same problem where using docker DHCP doesn't work but calling from the host does work.

[dotronglong]

hi @hyamanieu , thanks for your comment, I tried to test and here is the result. Since I don't have problem with it, I don't know what happened at your end, could you help to share your issue, so we can work together. For now I will reopen this issue for discussing potential issue.

Additionally, I did notice that I haven't updated the version of docker, but it should not cause any problems.

[hyamanieu]

@dotronglong thanks for your trial. You're trying to curl from your host using localhost: this works fine.

What doesn't work is using curl from another container within the same network, see response from OP.

he calls curl -v http://test_api:3030/v1/users from another container, not curl -v http://localhost:3030/v1/users

From another container, using the IP address works fine, only using container name doesn't work.

[dotronglong]

@hyamanieu Perhaps I missed that part, I would need to ask for more information, however, I remember that in order to have name mapping for hostname, they must be under same network. Could you share to me your whole docker compose files so I can check more on that? From my point of view, I think it is not something we could do with this application.

[dotronglong]

Close due to not having enough information. Please reopen if you found it necessary.

[hyamanieu]

I will try to work on an minimal example and reopen then
