Crashes while attaching VS Code container to running container

[shardulkumar79]

I am running open source code in a docker container and trying to connect vscode to that.

• VS Code Version:
• OS Version: Ubuntu 20

Steps to Reproduce:

1. clone the project repo git clone "https://gerrit.o-ran-sc.org/r/ric-plt/submgr" which has docker config as well.
2. create necessary .devcontainer.josn file in project root path. Now open vscode from the folder. It has multiple error exits.

The log doesn't indicate a crash. What exactly crashes?

[shardulkumar79]

This is not exactly a crash, but I see lots of messages with exit status 1 and building vscode server almost hangs

Exit code 1 for test -d ... indicates that the folder does not exist. We use that to check if the folder exists and it does not indicate a problem. Downloading seems to have taken a long time.

[shardulkumar79]

Is there a way to log in to container, manually perform all setup whatever is done by vscode plugin automatically? I mean to install vscode server, check Dir etc and fix it then and there. Once it is done, then I can simply connect to running container from my vscode. Why downloading is taking long time? When i run without vscode, it does not take that much long

[chrmarti]

This cannot be done manually. The download is done using HTTPS, are you using a network proxy?

[shardulkumar79]

yes

I suggest to check why that might slow down the download. In most cases the download either works at normal speed or fails completely when going through a network proxy.

[shardulkumar79]

I am using below given project which uses docker. I tried to use this VS Code but it fails at several steps. Can you please try it on your end? My intention is to use vscode with such projects

git clone "https://gerrit.o-ran-sc.org/r/ric-plt/submgr"

[chrmarti]

Make sure to run VS Code 1.64.2 and Remote-Containers 0.217.2. There is a fix in 1.64.2 for network proxies.

[shardulkumar79]

I have two queries here.

1. how can I select specific version of Remote-Containers extension in VS Code. I installed VS Code 1.64.2 but when i search for above said extension, it shows different version and i am not able to install get suggest one.

2. in the given project, the go code gets complied in an intermediate container and final compiled image is installed in a new container without its go build tools and source code just to reduce size. Then the intermediate container is deleted. So finally we have golang source code in host system and its installed binary on the docker container. Is there a way vscode intellisence would work based in the source code which is in host system and final built image? I understand it would have worked if container has both source code, compiled code and final image. But not in this case.
