Docker run 启动容器报错

今天在Windows下启动docker容器发现的三个错误：

• Ports are not available: exposing port TCP 0.0.0.0:1521 -> 0.0.0.0:0: listen tcp 0.0.0.0:1521: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.
  端口不可用，端口被占用

• Conflict. The container name “/aaa” is already in use by container “5ce25ceb6387357574ffb0c51bb96e6502a4a3cd16df49b7a3ad6795908482bf”. You have to remove (or rename) that container to be able to reuse that name.
  容器名称已经存在，删除容器后再执行

• Ports are not available: exposing port TCP 0.0.0.0:1522 -> 0.0.0.0:0: listen tcp 0.0.0.0:1522: bind: An attempt was made to access a socket in a way forbidden by its access permissions.
  端口禁止访问

  #执行查询端口后发现并没有端口被占用
  netstat -ano | findstr :1522
  

  # 查询动态端口范围
  netsh int ipv4 show dynamicport tcp
  # 当我们开启Hyper-V后，系统默认会分配给一些保留端口供Hyper-V 使用：
  >netsh interface ipv4 show excludedportrange protocol=tcpProtocol tcp Port Exclusion RangesStart Port    End Port
  ----------    --------1092        11911192        12911292        13911392        14911522        16215357        535712427       1252612628       1272712784       1288314343       1444214443       1454214543       1464214643       1474214743       1484214843       1494250000       50059
  

  1522正好在排除范围内，所以需要更换端口，修改成5522容器正常启动。
