How to enter collector docker container

[pavolloffay]

I would vote to have a small image with a shell.

At this moment, I don't think this is possible, as we use scratch images:

opentelemetry-collector-releases/distributions/otelcol/Dockerfile

Lines 10 to 20 in fe8f761

	FROM scratch
	ARG USER_UID=10001
	USER ${USER_UID}
	COPY --from=certs /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certificates.crt
	COPY --from=otelcol /otelcol /
	COPY configs/otelcol.yaml /etc/otelcol/config.yaml
	ENTRYPOINT ["/otelcol"]
	CMD ["--config", "/etc/otelcol/config.yaml"]
	EXPOSE 4317 55678 55679

You can certainly create new images based on this one. I'm moving this ticket to the releases repo, as I do think we need to discuss the best way to provide debugging containers.

[mx-psi]

On Kubernetes one can use the beta command kubectl debug to debug containers without a shell, but maybe we want to have non-scratch containers for people who use containers without Kubernetes.

[jpkrohling]

Either that, or have debug images. We have such for Jaeger, with delve also available, so that people can attach debuggers to the container.

[jpkrohling]

I'm closing, as the demand for this isn't apparently that high and kubectl debug seems to do the trick.
