搭建skywalking需要用到三个镜像:
elasticsearch：用来存储数据
skywalking-oap-server：Skywalking服务器
skywalking-ui ：Skywalking的UI界面
下载镜像
docker pull elasticsearch:7.9.0
docker pull apache/skywalking-oap-server:8.9.1
docker pull apache/skywalking-ui:8.9.1
Docker 单独镜像安装
安装elasticsearch
本机创建持久化目录，官方推荐
mkdir -p /Users/admin/Documents/data/elasticsearch/data
mkdir -p /Users/admin/Documents/data/elasticsearch/logs
持久化启动elasticsearch
安装elasticsearch并挂载文件
docker run -d --name=es7 \
--restart=always \
-p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-v /Users/admin/Documents/data/elasticsearch/data:/usr/share/elasticsearch/data \
-v /Users/admin/Documents/data/elasticsearch/logs:/usr/share/elasticsearch/logs \
elasticsearch:7.9.0
查看启动情况
docker ps -a
查看镜像日志
docker logs -f es7
验证ES
浏览器访问：http://localhost:9200/，返回：

"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
安装skywalking-oap
需要先安装好es才能安装opa
启动 skywalking-oap
docker run --name oap --restart=always -d \
-e TZ=Asia/Shanghai \
-p 12800:12800 \
-p 11800:11800 \
--link es7:es7 \
-e SW_STORAGE=elasticsearch7 \
-e SW_STORAGE_ES_CLUSTER_NODES=es7:9200 \
apache/skywalking-oap-server:8.9.0
-e TZ=Asia/Shanghai：指定时区。
--link es7:es7：关联es7容器，通过容器名字来解决ip会发生变更的问题。
-e SW_STORAGE=elasticsearch：设置环境变量，指定存储方式。
-e SW_STORAGE_ES_CLUSTER_NODES=es7:9200：设置环境变量，指定ES的地址
登录容器
docker exec -it oap bash
安装skywalking-ui
启动UI
docker run -d --name skywalking-ui \
--restart=always \
-e TZ=Asia/Shanghai \
-p 8088:8080 \
--link oap:oap \
-e SW_OAP_ADDRESS=oap:12800 \
apache/skywalking-ui:8.9.0
访问UI：http://localhost:8088/

docker-compose 安装
编写docker-compose.yml文件
https://github.com/apache/skywalking/tree/master/docker 官网有示例docker-compose.yml文件，我们只需要下载下来修改下即可。

启动容器
切换到docker-compose.yml文件下，然后执行一下命令：
docker-compose up -d
查看启动镜像
docker-compose ps

下载agent
下载源码包，然后解压取agent目录
https://archive.apache.org/dist/skywalking/8.9.1/
或
https://skywalking.apache.org/downloads/
解压获得agent.jar。修改conf配置文件
将地址改为skywalking地址
