💡 Feature request: healthcheck for docker container

[ingria]

Reference Issues

No response

Summary

At the moment it is impossible to check container health reliably enough: api is https only with self-signed cert, it is bound to container’s localhost, and there is no curl inside a container.

I suggest either adding a dedicated endpoint bound to 0.0.0.0, or adding a healthcheck instruction to the dockerfile.

Basic Example

I think that adding curl package to the image and making periodic requests to the health endpoint would be enough

Drawbacks

Adding this feature will make monitoring and automated alerts much easier

and there is no curl inside a container.

This is completely not true.

curl exist inside container (check Dockerfile). Endpoint for healthcheck also exist. Please refer to example in official docker-compose.yml configuration: https://github.com/remnawave/backend/blob/main/docker-compose-prod.yml#L30

@kastov i meant remnawave/node container, not remnawave/backend. Sorry for the confusion, i didn't notice that I've been redirected to another repository while creating issue on remnawave/node.
