I would like to be able to attach to a running container's terminal in the Komodo web ui.

@mbecker20 commented on GitHub (Sep 13, 2024):

I'm not entirely sure how to accomplish this task.

I do have some idea to kind of fake it, achieving something close to an attach using a terminal client interface, and sending every line user executes atomically to docker exec.

I think this docker exec feature is much simpler, and should be able to do everything needed. But it's not docker attach and won't be just like docker attach over ssh. Mainly, the responses won't be stream back, but rather will resolve fully and send back whole response at once. The different wouldn't be noticeable for short running tasks but for anything long running, would give no feedback.

Let me know if this docker exec feature would be useful to you, as a precursor to potential full docker attach with streaming responses

I think having a button in komodo that runs something like 'docker exec -it mycontainer sh' for whatever the container is would be hugely beneficial.

It's easy enough to run over ssh but having the feature in the komodo web ui would be great

Would also love to see this. Dockge offers this ability; you can connect directly to the container's shell in the UI and it lets you switch from bash to sh if bash isn't supported. It's super useful and one of the main things missing for me that stops me migrating from dockge solution.

Same thing here. It is a really useful feature, so would love to see this implemented. Since for example dockge and portainer have this feature, it should be possible to get some ideas on how one could go about implementing it from there perhaps?

Docker exec one liners will be useful as i think majority of the use cases is this, for debugging or for executing quick backend commands.

I'm not sure if that's what dockge also does. For portainer, i think it's a full attach?

I'm no expert in this, but found the following issue on github which at least seems to contain some hints on how to accomplish this? (eg. running an interactive shell in a container using the API)

Hi!
Maybe you could use ttyd:
https://github.com/tsl0922/ttyd

See the usage examples in the ttyd wiki.

You could run something like:
ttyd <ttyd_options> docker exec -it container bash
It will then start a new web terminal with this command.

As I see it, the problem is that the developer does not know how to implement this task at the moment.

It's coming! #446

This will initially only be the implementation for shell access. Exec still has to be executed manually. But Exec will most certainly be built on top of that.

container exec should be simple on top of the shell access in #446 . I'm going to go ahead and implement it before releasing 1.17.4

@nic96 commented on GitHub (May 9, 2025):

Wouldn't docker attach be just as simple as docker exec -it now that you have a terminal feature? I tested that it works attaching with the terminal feature e.g docker attach --detach-keys=ctrl-d service-name.

The tty and std_open options need to be in the docker compose service to be able to attach and interact:

services:
  hello_world:
    image: hello-world
    tty: true
    stdin_open: true
