dev container issue: Is it possible to set "fetch control manifest" as optional ?

[tymaoa]

I work in an air-gap environment, so it will hang up to 4 mins everytime I reopen or rebuild the container:

Failed to fetch control manifest: connect ETIMEDOUT 185.199.111.153:443

Is it possible to skip this step?

We have the same issue. Adding this option would really improve the start of my day.

I guess your network is dropping the connection attempt, the connecting would hang up much faster if your network (a firewall?) would explicitly reject the connection. Have you looked into that?

A setting in VS Code also makes sense.

I am running into this issue as well. Does anyone have any workarounds for the time being?

[vially]

The current workaround that I have settled on is changing the modified date of the cached control manifest prior to starting the devcontainer. This relies on the fact that the current implementation skips downloading the manifest if it's been modified less than 5 minutes ago.

$ touch /tmp/devcontainercli-$USER/control-manifest.json

And, if you want to go the extra mile, you can put this in a systemd-timer or cron-job to avoid having to manually run this command before starting a devcontainer.

My workaround is what the contributor said.

I contacted my network admin and they rejected all requests to containers.dev instead of dropping them. Now I no longer encounter such long waits.

Looking forward to customizable timeout too. Have same error:

But as you can see i haven't got an error type.

I'm not sure does this problem cause hang, but I don't see other slow tasks.

@vially what do you think about adding 127.0.0.1 containers.dev to /etc/hosts? Worked for me.

Sure, that works too (although it requires root access which may not always be available).
