go-zero接入skywalking实现链路追踪的详细教程

#数据存储用ES，搭建ES
docker run -d -p 9200:9200 -p 9300:9300 --name es -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms128m -Xmx256m" elasticsearch:7.16.3

# 搭建skywalking-oap服务，这里用的是8.9.1版本，oap服务需要关联ES
docker run --name skywalking-oap \
--restart always \
-p 11800:11800 -p 12800:12800 -d \
-e TZ=Asia/Shanghai \
-e SW_ES_USER= \
-e SW_ES_PASSWORD= \
-e SW_STORAGE=elasticsearch \
-e SW_STORAGE_ES_CLUSTER_NODES=192.168.1.234:9200 \
-v /etc/localtime:/etc/localtime:ro \
apache/skywalking-oap-server:8.9.1

# 搭建skywalking-ui界面，需要关联oap服务
docker run -d \
--name skywalking-ui \
--restart always \
-p 8090:8080 \
--link skywalking-oap:skywalking-oap \
-e TZ=Asia/Shanghai \
-e SW_OAP_ADDRESS=http://skywalking-oap:12800 \
-v /etc/localtime:/etc/localtime:ro \
apache/skywalking-ui:8.9.1
