当启动的服务端口号被占用后的错误，报错信息：
ERROR: for sc-gateway-web Cannot start service gateway-web: failed to create endpoint sc-gateway-web on network docker-compose_sc-net: failed during hnsCallRawResponse: hnsCall failed in Win32: The process cannot access the file because it is being used by another process. (0x20)
我是win 10环境，查找端口占用的应用程序方法如下：
netstat -ano|findstr "8443"
tasklist|findstr "1204"
找到应用程序，关闭后，就能正常启动了
