Question

• What do you want to know?

We have an official repository for the docker images and compose at https://github.com/apache/skywalking-docker and it works perfectly. Should we remove the docker folder in this repository? Our developers have tried the docker folder and couldn't find the images published to the docker hub.

Bug

• What happen?
  If possible, provide a way for reproducing the error. e.g. demo application, component version.

The docker file in this repo is for development only. Build the current version to an image for the developer.

We need to use cmake to build the image locally.

Got it. In this case, should we add a README.md to the folder to clearly state the purpose? Most users will try to start it and find it doesn't work out of the box. In the readme, we can direct them to the right docker repository if they just want to set up a development environment. I can create a PR for it.

Yes. That makes sense. Would you like to submit a pull request?
