Jekyll Container not completing setup about templates

[samruddhikhandale]

I tried to open a dev container with the jekyll template and it was successful.

I wonder if the docker cache is interfering with the inspect?

On my local-machine, I cleared my cache (both page and RAM) and ran into the same error. Because local-machines can be fickle, I used a codespace as well; however, I still ran into the error.

Here is the creation-log:

It fails at the same point as it did on my local-machine (docker inspect).
The error-point (async Qse) is consistent between rebuilds.

I’m assuming the error-code (1302) is a codespace-output since the process exited-1 and the error-json did not contain the error-code.

However, I could be wrong.

I won’t pretend to know why this may be happening.
The build was successful on your end, and this error has not happened before.

Just for good measure I ported the most-recent Jekyll-devcontainer into a new repository, with a new codespace, and still got the same error.

@samruddhikhandale I will say though; the more I think about it, the more I think it’s an issue with the "2.7 bullseye" cross-compiler.

All of the boxes seem to be checked:

• Running on some machines, but not others, despite being the same build
• Failing during an async task-queue, which is most likely bootstrapping processes. This would indicate unknown instructions being sent to the kernel.
• All other bullseye-containers being functional and not running on 2.7

This is just speculation, since I have no idea what the source is doing, but it’s interesting to think about

Looks like you copied over the jekyll template instead of adding it from Add dev container configuration files... command? that's the reason why it fails in a codespace as it has unresolved ${templateOption:imageVariant} variable.

@meg-io can you create template using the command pallet and retry?

Yes, this solved the issue, I will mark it as closed. Thank you for the assistance.

Addendum:

The devcontainer worked recently, even with the unresolved variable, so I assumed it wasn’t causing the error. This is not the case; if you are in a similar situation, resolve the variable.

After checking the other four containers that were working, they all had the variable resolved - so the solution checks out. By code or by music, KISS reigns supreme.

Working solution (as per @samruddhikhandale):

1. Open VSCode Command Palette
2. Use Add dev container configuration files...
3. Select desired devcontainer-configs
4. Use Full Rebuild

If you happen to be using the devcontainer outside of visual-studio, the configuration-file (devcontainer.json) can also be manually adjusted. Adjust ${templateOption:imageVariant} to the desired option.
