How do you generate devcontainer-collection.json?

[SiegfredRodriguez]

TLDR; How do you generate devcontainer-collection.json?

I attempted creating my own template collection, however i get an error.
[21 ms] (!) ERR: Failed to fetch devcontainer-collection.json

As per documentation, devcontainer-collection.json is supposed to be auto generated,
but there seems to be no documentation on how or when this is done.

I cloned the templates project, modified it and executed this command :
devcontainer templates publish -n SiegfredRodriguez/jdk-postgres -r g hcr.io .

Looking at your repo here where you run the GitHub action, I'd suggest first fixing the issue here and trying to run the tool again.

You can fix this by renaming src/jdk-postgres/.devcontainer/.devcontainer.json to src/jdk-postgres/.devcontainer/devcontainer.json (without the leading dot on devcontainer.json). I think that will solve your issue

That specific error is a bit misleading, thank you for pointing that out

Thank you very much, the error message was confusing.
Putting the dot before the json was muscle memory.

I've removed that error message in devcontainers/cli#925 - thanks again!
