修改容器名称，参考

 docker rename 原容器名称 新容器名称

管理网络，参考

 # 清理此容器的网络占用
docker network disconnect --force 网络模式 容器名称
docker network disconnect --force bridge containerName
 
# 简查是否还有同名容器占用
docker network inspect 网络模式
docker network inspect bridge
# 查看创建的所有网络
docker network ls
 
# 查看日志
docker logs -f 容器名

测试
编写1个vue项目

 # 设置默认路由
axios.defaults.baseURL = 'http://124.222.5.107:8596'
 
# 发送请求
export default {
  data() {
    return {
      books: []
    }
  },
  created(){
    this.$http.get("testmysql").then(resp => {
      console.log("mysql resp--->" + resp.id + ":" + resp.name + ":" + resp.price)
    }).catch(err => {
      console.log(err)
    }),
    this.$http.get("testredis").then(res => {
      console.log("redis res--->" + res)
    }).catch(err => {
      console.log(err)
    })
  }
}
