Docker netdata documentation

[pgassmann]

• The Readme on Dockerhub does currently show general information about netdata and not much about the usage of the container image.
• The Wiki Page contains a link that is no longer valid.
• The correct link is now docs.netdata.cloud https://docs.netdata.cloud/packaging/docker/
• There is a README in the netdata/packaging/docker with good information on the usage of the docker image: https://github.com/netdata/netdata/tree/master/packaging/docker

@paulfantom Can the Information on Dockerhub be changed to show usage information for the docker image? Is this Readme added manually?

@paulfantom Can you add the information on how to specify additional parameters.

• cli: append the desired options to the cli docker run -d [...] netdata/netdata -i 192.168.1.1.
• docker-compose: command: '-i 192.168.1.1'

It would also be helpful to have a direct link from the docs to dockerhub. on https://docs.netdata.cloud/packaging/docker/ to https://hub.docker.com/r/netdata/netdata/

The Wiki Page contains a link that is no longer valid.
The correct link is now docs.netdata.cloud docs.netdata.cloud/packaging/docker

Link fixed.

Regarding additional info in the README, please go ahead and update it. We are more than happy to get help with the documentation
@paulfantom will review the changes for accuracy.

So it's just the following that will remain:

Can the Information on Dockerhub be changed to show usage information for the docker image? Is this Readme added manually?

[paulfantom]

Readme in docker hub is added manually and I will try to add sth to sync it via CI system with a file located at packaging/docker/README.md

@cakrit could you please take care of it? The README on docker hub, should docker related.

[paulfantom]

@pgassmann we are using ENTRYPOINT directive in our Dockerfile, so the way to add any parameters to netdata binary is to use CMD/command ( https://docs.docker.com/engine/reference/builder/#cmd ). We are not planning on duplicating documentation for how this method is implemented in various tools (docker cli/docker-compose/k8s manifests/other).

[cakrit]

I spoke with @paulfantom and I will do a PR to improve the docker documentation today. The automated update will come a bit later.

#4914 updated the README, https://hub.docker.com/r/netdata/netdata/ is also updated.
Thank you for your feedback @pgassmann
