由于 & 特殊字符会导致运行失败,所以含有&等特殊字符的变量需要单引号包裹

• 原生 docker run写法

docker run -d \
-p 9001:8080 \
-e admin.root.user.name=root \
-e admin.root.user.password=xxx \
-e admin.registry.address='nacos://xxx.cn:8848?group=DEFAULT_GROUP&namespace=test' \
-e admin.config-center='nacos://xxx.cn:8848?group=DEFAULT_GROUP&namespace=test' \
-e admin.metadata-report.address='nacos://xxx.cn:8848?group=dubbo&namespace=test' \
--network swarm-overlay \
--name dubbo-admin apache/dubbo-admin

• docker-compose写法
