Docker Images

This folder contains Dockerfiles that are used to build our OAP Docker images and UI Docker image. If you want to use the Docker images, please check the user guide for OAP and the user guide for UI.

Quickstart

You can use Makefile located at the root folder to build a docker image with the current codebase.

make docker

It not only contains the process of building a docker image but also includes all the required steps, for instance, init workspace, build artifact from scratch. It builds two images, OAP, and UI.

docker image ls | grep skywalking
skywalking/ui                                   latest              a14db4e1d70d        6 minutes ago       800MB
