'Attach Visual Studio Code' does nothing, throws no error, no logging #5100

andyljones · 2021-05-26T12:03:48Z

VSCode Version: 1.56.2
Local OS Version: macOS Big Sur
Remote OS Version: Ubuntu 18.04.5 LTS
Remote Extension/Connection Type: Kubernetes
Logs: None

Steps to Reproduce:

Open the Kubernetes UI, right click on a pod, 'Attach Visual Studio Code'.
The 'Activating Extensions' busy icon shows up for a few seconds, then nothing happens.
Nothing shows up in the vscode dev console, nothing shows up in any of the output panes. None of the 'Remote-container: show log' commands seem to do anything. No 'remote extension host' output channel.

Does this issue occur when you try this locally?: N/A
Does this issue occur when you try this locally and all extensions are disabled?: N/A, can't do this with no Kubernetes extension

I suspect there might be a million reasons for this, and I'm working in a 'heavy' environment that'd be difficult to offer you a minimal reproduction for. So rather than giving you every detail of my setup, I think it's better to ask: how'd I go about getting enough information to isolate the problem? I haven't spotted any obvious log level settings.

(Aside: I saw something somewhere that said the 'Attach Visual Studio Code' menu entry is your folks' turf rather than the vscode-kubernetes-tools folks', but say if I've got that wrong)

chrmarti · 2021-05-27T11:01:53Z

Is there anything in F1 > Remote-Containers: Show Container Log?

andyljones · 2021-05-27T18:06:11Z

That command doesn't appear to do anything (3. above). There's no appropriately-named option in the Output dropdown either.

chrmarti · 2021-05-31T12:21:58Z

Is there anything in the Extension Host output channel? It sounds like the extension might fail to activate, but that would usually show an error notification.

andyljones · 2021-05-31T12:28:55Z

On launching vscode, there's a bunch of loads and activations in that channel, with the two remote-related lines being

[2021-05-31 13:23:36.813] [exthost] [info] ExtensionService#_doActivateExtension ms-vscode-remote.remote-containers {"startup":false,"extensionId":{"value":"ms-vscode-remote.remote-containers","_lower":"ms-vscode-remote.remote-containers"},"activationEvent":"onStartupFinished"}

When I click on the Kubernetes icon on the LHS, there're a few more:

But expanding the 'pods' list and clicking 'Attach to Visual Studio Code' generates no further logs; just the 'Activating Extensions' spinner in the status bar for a few seconds then nothing.

andyljones · 2021-06-22T08:57:33Z

Is this pretty much DOA then - you've not seen anything like this, and there's no way for me to get more information on what's causing the behaviour?

caesarnine · 2021-06-22T16:37:19Z

I'm having the same issue. When I've setup the Kubernetes extension locally I get the following error when trying to Attach to a running pod:

error running command remote-containers.attachToK8sContainerFromViewlet: Running the contributed command: 'remote-containers.attachToK8sContainerFromViewlet' failed.. This is likely caused by the extension that contributes remote-containers.attachToK8sContainerFromViewlet.

When I'm SSHed into a server and try the same via the Kubernetes extension in that window I don't receive an error message, and nothing happens. I can use the Kubernetes extension normally otherwise (so start a terminal, view logs, etc).

caesarnine · 2021-06-22T16:44:44Z

I just got it working for me - the logs were showing this

[2021-06-22T16:41:34.250Z] Start: Run: kubectl config current-context
[2021-06-22T16:41:34.298Z] Stop (48 ms): Run: kubectl config current-context

and in my case I'm using EKS so I ran the following

aws eks update-kubeconfig --name <insert_cluster_name>

and now the Attach context menu item works.

chrmarti · 2021-06-23T05:46:02Z

Is there a better way to determine which cluster is shown in the Kubernetes viewlet than kubectl config current-context?

adambozson · 2021-08-15T17:11:20Z

@caesarnine Which logs? I'm getting the same behaviour - works locally but silent failure when I try in a remote SSH session.

Running aws eks update-kubeconfig --name <insert_cluster_name> does not solve it for me.

chrmarti · 2021-08-23T12:23:38Z

Attaching to a Kubernetes pod while connected with Remote-SSH is currently not supported. I'll make sure the action is not show in the context menu in this case.

andyljones · 2021-08-31T11:11:27Z

I think that @caesarnine 's error is subtly different from the one @adambozson and I are seeing. I still am not getting any logs at all, and it's not fixed by update-kubeconfig.

Adam, here are some less-than-usual things about my setup - mind telling me if you match on any?

Using an M1 Mac
Connecting to AWS
Previously had problems with the path being out-of-order in the vscode terminal
Right-clicking on a workload and hitting Terminal works fine, even though Attach Visual Studio Code doesn't.

chrmarti · 2021-09-01T05:54:50Z

@andyljones How are you connecting to AWS? Are you in a local VS Code window when you run Attach Visual Studio Code?

andyljones · 2021-09-01T08:32:17Z

Yes, I'm in a local VS Code window. I'm connecting through a script that starts with SSO and ends with a bunch of kubectl port forward, kubectl exec and kubectl cp commands to control the remote box.

For reference, the other commands in the Kubernetes right-click menu work - like get or port forward - work fine.

chrmarti · 2021-09-09T08:40:47Z

Adding logging to help track this down. (Will be in the next version for VS Code Insiders.)

andyljones · 2021-09-10T15:05:23Z

Still nothing. Same extension host logs as before, same spinner when I 'Attach Visual Studio Code', and no further logs to go with it. Insiders version

I suspect this might be hard to believe, so I've attached a little vid so we can see if I'm doing anything daft.

@andyljones Could you retry with Remote-Containers 0.195.0 and check the container log (F1 > Remote-Containers: Show Container Log)?

andyljones · 2021-09-15T13:58:38Z

Updated to 0.195.0 and tried F1 > Remote-Containers: Show Container Log; the show container log command itself triggers the same 'Activating Extension' spinner for a few seconds and then nothing happens. No log window appears.

e: I've just noticed that the 'Runtime Status' page of Remote - Containers shows as 'Not yet activated', and going to the Remote Explorer the containers spinner runs permanently. I wonder if this something about my Docker install. Let me try some experiments...

andyljones · 2021-09-15T14:41:53Z

b i n g o

I had $DOCKER_HOST set to a dead URL, so every docker command was hanging indefinitely. Presumably 'run docker' happens somewhere very early in the Remote-Containers extension setup, before it gets to logging anything.

A minimal example is

export DOCKER_HOST=ssh://bad@url.local 
docker

which hangs on my Mac. Have that variable set somewhere that vscode can see it and loading the extension (presumably) times out and fails.

Anyway now I've removed that line from my zshrc, Attach works fine! Thanks so much for your patience!

andyljones · 2021-09-15T15:11:17Z

And just checked my ps -ef | grep ssh locally for another reason and I've found a bunch of hanging

ssh -l ajones -- aj-server.local docker system dial-stdio

calls, which I reckon are the root of this.
