我在撰写模式下运行了两个容器。容器可以通过IP相互通信,但不能通过容器名称相互通信-无法解析。
Docker网络检查容器的运行位置
docker inspect mycompose

尝试按容器名称在另一个容器中ping一个容器:
PS C:\inetpub\wwwroot> ping mycompose_brimdb_1
Ping request could not find host mycompose_brimdb_1. Please check the name and try again
尝试按服务名称ping:
PS C:\inetpub\wwwroot> ping brimdb
Ping request could not find host brimdb. Please check the name and try again.
尝试通过IP对同一容器执行ping操作
PS C:\inetpub\wwwroot> ping 172.25.113.185
