Same issue here. I am looking at running docker without Docker Desktop in Windows, and I have a following setup as docker compose that I start before attaching:

  • Dockerfile content:
FROM mcr.microsoft.com/vscode/devcontainers/base:alpine
  • docker-compose.yaml:
version: '3.3'

services:
  code:
    build:
      context: .
      dockerfile: ./Dockerfile
    container_name: 'code'
    volumes:
      - ..:/code:cached
    command: /bin/sh -c "while sleep 1000; do :; done"
    cap_add:
      - SYS_PTRACE
    security_opt:
      - seccomp:unconfined
  server:
    image: 'plantuml/plantuml-server:jetty'
    container_name: 'server'
    environment:
      PLANTUML_LIMIT_SIZE: 8192
    ports:
      - "8080:8080"
    expose:
      - "8080"
  • devcontainer.json:
{
	"name": "code",
	"dockerComposeFile": "./docker-compose.yaml",
	"service": "code",
	"shutdownAction": "stopCompose",
	"settings": {
		"terminal.integrated.shell.linux": "/bin/bash",
		"plantuml.render": "PlantUMLServer",
		"plantuml.server": "http://server:8080"
	},
	"workspaceFolder": "/code",
	"extensions": [
		"jebbs.plantuml"
	]
}

After the docker compose is up, attaching VS code to the code container yields the error message as Mikael described.

As Docker Desktop is no longer free of charge for commercial users, I would assume many people might start switching off using it for development, and therefore might browse the possibility of running docker without Docker Desktop, and thus could be seeing the same errors.

It'll be great if such error can be fixed; or if it is not a bug, maybe help us resolve our problem. Thanks!

@MikaelUmaN Are you using Docker Desktop for Windows or some other type of installation? Is the problem still present using VS Code Insiders? (https://code.visualstudio.com/insiders/)

@zhongjie-cai How did you install Docker?

I am using Docker Desktop latest version.

I have had this problem for quite a while so I don't know that things would work better in the insider version.

I will give it a try when I can.

Can you tell me how I can provide more diagnostic info for you guys?

@Tyriar This error message seems to originate from terminal code. Is there a way to diagnose this further?

I'm having a similar error. Can't start my WSL Ubuntu distro in VS Code, but it works fine through Powershell / cmd. Same error messages.

EDIT: Solved my issue. VM was missing network connectivity.

I turned on debugging for the extension (Settings -> Extensions > Remote - WSL) and got this in the terminal after reloading VS Code:

I went into the VM and tried to find the VS Code extension files and eventually noticed that the machine didn't have network connectivity. Which led me to this microsoft/WSL#5336 (comment). Now the machine has network connectivity and I can access the VM through VS Code.

@chrmarti you could check why

vscode/src/vs/workbench/contrib/terminal/browser/remoteTerminalService.ts

Line 194 in 8b9aed7

const remoteEnv = await this._remoteAgentService.getEnvironment();
is returning null

I see null would be returned if there was some error and also as a fallback when the channel is not established: https://github.com/microsoft/vscode/blame/main/src/vs/workbench/services/remote/common/abstractRemoteAgentService.ts#L55

@alexdima Can we add logging for these two cases? If we are hitting this code path too often for logging each time, we could maybe throw / propagate an error and log it in those cases where this is fatal.

@Tyriar I think I added the throw here when you were out last year. It is expected that sometimes we cannot connect to a remote, so it is expected that the env will be null in those cases. This connection error is handled somewhere else (it can even be delegated to be handled by the resolver extension). So, although an error case, it is expected that the environment is null and most pieces of code should try to not complain too loudly about that. But last year (when you were out), I could not figure out how to hook into our system a terminal process that is "dead"/"N/A"/etc. So I'd like to ask you what we can do to fail the creation of a terminal but in a silent way.

@chrmarti would a silent error be good here? Normally all terminals that fail launch show a notification

@alexdima null seems to indicate cancel due to some problem then? Is the cause of it logged somewhere? If so, silently failing the terminal's creation sounds fine, otherwise the original cause could be thrown as an error for the terminal error handling to log and display.

Is the cause of it logged somewhere?

Yes, the error is logged and handled somewhere else. But in our system we have tens of callers to IRemoteAgentService.getEnvironment(). It is expected that IRemoteAgentService.getEnvironment() will return null. Callers of IRemoteAgentService.getEnvironment() need to be able to handle null without throwing.

When I implemented terminal reconnection last year I was not familiar enough with the terminal code-base in order to handle the null value silently. This throw statement should be removed by someone familiar with the terminal code-base. The implication is that createProcess should be allowed to return null if it cannot create a terminal, silently. That will cause a ripple in the terminal code-base. But maybe the code can return a fake ITerminalChildProcess that doesn't do anything, I don't know what is best suited here.
