Docker container port mapping missing in docker desktop UI

[shriram1056 (shriram saravanan)]

port mapping is missing for container in windows docker desktop UI but when i run docker ps I can see the port mapping.

docker version 4.3.0. I have tried the latest version (4.3.7) as well.

Please, share the output of

docker version

When you do, please use code blocks (backticks not single quotes):

```
output
```

There is no Docker 4.3.0 and the latest Docker Desktop is also Docker Desktop 4.37.2

Can you also share a screenshot of Docker Desktop where you expect to see the port mapping and the command line output where you actually see it?

Also do you have problem with connections or you just don’t understand why the port maping is not shown on the UI?

The comand line output can show the exposed ports as well, but that is not the same as forwarded ports

sorry, put the wrong version.

I’m expecting port forwarding for the postgres container in docker desktop

shrir@shriram MINGW64 ~
$ docker ps
CONTAINER ID   IMAGE                                COMMAND                  CREATED         STATUS         PORTS                     NAMES

eec6b2222a92   testcontainersofficial/ryuk:latest   "/app"                   8 minutes ago   Up 8 minutes   0.0.0.0:50259->8080/tcp   testcontainers-ryuk

no problem with connection, just the port forwarding not showing up on docker desktop sometimes as you see it’s always listed when i run docker ps.

That port should indeed be visible in Docker Desktop. I found this issue which could be related

Forwarded ports are not rendered at container's start

Can you confirm if you stop Docker Desktop and start again, the port numbers appear?

[meyay (Metin Y.)]

Doesn’t it make more sense to install the latest version?

Note: On Windows it is 4.37.1, on mac it is 4.37.2 (with has bug fixes specifc to the mac version)

[rimelek (Ákos Takács)]

Of course @meyay is completely right. By the time I came back to your post, I forgot the version number. So first try to update Docker Desktop

[shriram1056 (shriram saravanan)]

I did use the latesr version and had the same issue. So, i switched version that previously woked for me and i had the same issue

[rimelek (Ákos Takács)]

@shriram1056

I did use the latesr version and had the same issue

The second thing I forgot. Great Have you also tested what I wrote previously?

@rimelek

Can you confirm if you stop Docker Desktop and start again, the port numbers appear?

Depending on that, you can either comment on the previously linked existing issue or create a new one

[shriram1056 (shriram saravanan)]

Yes, i have. The port number does appear on restarting the container but since the containers are created as a part of test run. I’d need to restart it multiple times due to this

[rimelek (Ákos Takács)]

I didn’t think it was a solution, but we can’t solve it. You can report it on GitHub where developers can see it. Since there is an existing issue describing the same problem, you can also comment on that.
