This folder contains Docker files for SkyWalking developers/committers to build images manually. If you want to start a SkyWalking backend server with docker-compose for your integration, please visit https://github.com/apache/skywalking-docker repository.

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

make docker

It doesn't contain 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
skywalking/oap                                  latest              2a6084450b44        6 minutes ago       862MB

There're some environment variables to control image building.

The hub of docker image. The default value is skywalking.

The tag of docker image. The default value is latest.

The elasticsearch version this image supports. The default value is es6, available values are es6 and es7.

For example, if we want to build images with a hub foo.io and a tag bar, and it supports elasticsearch 7 at the same time. We can issue the following commands.

export HUB=foo.io && export TAG=bar && export ES_VERSION=es7 && make docker

Let's check out the result:

docker image ls | grep foo.io
foo.io/ui                                       bar                 a14db4e1d70d        9 minutes ago       800MB
foo.io/oap                                      bar                 2a6084450b44        9 minutes ago       862MB

From the output, we can find out the building tool adopts the files stored in oap-es7.

We can start up backend cluster by docker-compose

cd docker
docker compose up

docker/.env file contains the default TAG and elasticsearch tag(ES_TAG).
