Could not establish connection to "my-app.devspace": Could not resolve hostname #2434

Open oconnor17 opened 2 years ago

oconnor17 commented 2 years ago

What happened?

I was following the IDE integration example, and got the following error from Visual Studio

What did you expect to happen instead?

I expected to see the source code inside the container displayed by VSCode.

It should be noted that I am running VSCode using WSL2 on Windows. The example is running on my Ubuntu Laptop (See Issue #2420)

How can we reproduce the bug? (as minimally and precisely as possible)

On a windows machine, running WSL2, I followed the example instructions

https://www.devspace.sh/docs/ide-integration/visual-studio-code#tldr

# Clone the example project
git clone https://github.com/loft-sh/devspace-vscode-example.git

# Switch to the folder
cd devspace-vscode-example

# Open Visual Studio Code in a Container
devspace dev -n my-namespace

Local Environment:

$ kubectl version --short
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.25.4
Kustomize Version: v4.5.7
Server Version: v1.23.8
WARNING: version difference between client (1.25) and server (1.23) exceeds the supported minor version skew of +/-1

Anything else we need to know?

The following link describes what I think is root cause and a work-around.

https://zitseng.com/archives/20325/amp

Devspace generates the necessary SSH configuration to connect to the devmode container here:

Problem is that when running VSCode via WSL2 it is running on the host windows, meaning it's SSH configuration is located here. Explaining the "could not resolve hostname" error.

oconnor17 commented 2 years ago

Work-around

First create a batch script: C:\Users\\bin\ssh.bat

C:\Windows\system32\wsl.exe ssh %*

Secondly, configure the VScode Remote - SSH extension to use this batch script when running ssh operations.

Ran into this issue - glad to see it's been caught.

FabianKramm commented 2 years ago

@oconnor17 thanks for creating this issue! We will take a look and come back to you!

pratikjagrut commented 2 years ago

@oconnor17 @cslovell can you connect the devcontainer using ssh my-app.devspace -v? Can you post the output of the command?

oconnor17 commented 2 years ago

This is the output from a Powershell terminal

C:\Users\oconnor17> ssh my-app.devspace -v
OpenSSH_for_Windows_8.1p1, LibreSSL 3.0.2
ssh: Could not resolve hostname my-app.devspace: No such host is known.

From within WSL2 (Running Ubuntu), it works as expected

A second attempt using the windows powershell terminal.

I'm specifying the path to the configuration files generated by devspace (within the WSL file system home). This time it connects, but there are two issues with the SSH private key.

To conclude, the work-around configures the windows application (Visual Studio Code) to use the WSL implementation of SSH, instead of the windows ssh. The problem was documented in this article I found. Unclear to me if there is a better solution.

pratikjagrut commented 2 years ago

@oconnor17 Could you please print the file permissions of devspace-generated ssh keys, from both wsl and from the windows system?

I'm not wsl or windows expert and I very well could be wrong here, but it seems like there could be some file permission issue between wsl and windows. They may not be able to map it correctly with each other’s filesystem. You may need to add/update some file permission configurations between wsl and windows.

I understand that regarding the vscode hack of this issue, they’re instructing vscode to use ssh from wsl and hence it works fine.

@oconnor17 @cslovell can you connect the devcontainer using ssh my-app.devspace -v? Can you post the output of the command?

In my case I get an error indicating "connection refused":

FabianKramm commented 2 years ago

@cslovell @oconnor17 have you installed DevSpace on the host system or within WSL2 itself? In the latter case I don't think there is much we can do as we would need to detect WSL2 somehow and then try to figure out the ssh path on the host system, which I don't think is a good idea in general.

I'm running Devspace within WSL2, which I think is the more typical usecase. It is possible to detect you're running within WSL, but I'm not clear if it helps solve the problems....

$ uname -a
Linux DE21083025 5.10.16.3-microsoft-standard-WSL2 #1 SMP Fri Apr 2 22:23:49 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Problem 1: Two locations for SSH configuration

To fix this issue you'll need to write the SSH config files to two locations to cater for both windows and linux SSH clients:

See how it could be possible to have two different usernames?

Problem 2: File permissions

Conclusion

Strictly speaking this is not a Devspace problem. VScode is running as a windows program, outside the WSL2 virtual machine.

Why don't we just document this problem and the work-around in the Devspace documentation? Means WSL2 users will not think Devspace is broken.

@oconnor17 We'll document this somewhere if we don't find a better solution, but before that, I was looking if we could have a workaround for both issues.

Have you tried this fix from MS docs, and does this work? /etc/wsl.conf 

[automount]
enabled = true
options = metadata,uid=1000,gid=1000,umask=0022

In my case I get an error indicating "connection refused":

$ ssh app.project.devspace -v

@cslovell This usually happens when the server is stopped. Can you confirm if the devspace dev is running while trying ssh? And does the vscode workaround works for you?
