拉取镜像
docker pull apache/skywalking-ui:10.0.1
docker tag apache/skywalking-ui:10.0.1 xxx/xxx/skywalking-ui:10.0.1
docker push xxx/xxx/skywalking-ui:10.0.1
docker pull apache/skywalking-oap-server:10.0.1

源码制作镜像
# 拉取源码
git clone -b v10.0.1 https://github.com/apache/skywalking.git
# 进入源码目录
cd skywalking
# 为了提高maven依赖下载速度,需要在~/.m2目录下创建settings.xml文件
# 修改settings.xml文件,指定私服nexus地址
# 必须指定JAVA_HOME变量
export JAVA_HOME=/home/xxx/镜像制作/jdk-17.0.2
# 运行制作镜像脚本
nohup make docker SKIP_TEST=true OAP_NAME=skywalking-oap-server UI_NAME=skywalking-ui HUB=xxx/xxx TAG=10.0.1 &
# 查看制作的镜像
docker image ls | grep skywalking
官网下载程序包制作镜像
# 下载可直接运行的程序包
wget https://dlcdn.apache.org/skywalking/10.0.1/apache-skywalking-apm-10.0.1.tar.gz

参考资料
- skywalking源码
配置文件参考:
https://github.com/apache/skywalking/blob/master/oap-server/server-starter/src/main/resources/application.yml
- K8S部署skywalking9.3版本
- skywalking使用ES做存储在K8S上的部署,使用实践
- skywalking-helm
- skywalking-docker
Since SkyWalking 8.8.0, the Dockerfiles are merged into the OAP repo and the Java agent repo respectively, this repo is archived and not maintained anymore.
- 使用源码制作镜像
- skywalking-oap server 环境变量支持
表格往右拖动,可以看到环境变量名称和默认值。
