问题描述
在两台机器上，分别为服务器A与主机B，其中服务器A上部署OAI核心网，主机B上部署容器版ueransim。两机器用一根网线连接。两台机器的连接如此。但是ueransim接入核心网后无法通过创建的uesimtun传输数据到核心网。
解决思路1——机器网卡设置到192.168.70.0网段
将机器物理网卡网段设置到与核心网所在网段一致，192.168.70.x，ueransim直接接入。
测试过程
两机器分别设置如下：
核心网A：
ens38:
addresses: [192.168.70.12/24]
dhcp4: no
gateway4: 192.168.70.1
nameservers:
addresses: [8.8.8.8,144.144.144.144,255.255.255.255]
主机B：
ens39:
addresses: [192.168.70.13/24]
dhcp4: no
gateway4: 192.168.70.1
nameservers:
addresses: [8.8.8.8,144.144.144.144,255.255.255.255]
两者可以互相ping通，但开启核心网后却无法互相ping通
进行如下修改，将对方网口作为自己的网关后，在开通核心网后可以ping通，但依旧无法ping通核心网
核心网A：
ens38:
addresses: [192.168.70.12/24]
dhcp4: no
gateway4: 192.168.70.12
nameservers:
addresses: [8.8.8.8,144.144.144.144,255.255.255.255]
主机B：
ens39:
addresses: [192.168.70.13/24]
dhcp4: no
gateway4: 192.168.70.13
nameservers:
addresses: [8.8.8.8,144.144.144.144,255.255.255.255]
经过在服务器A抓包，发现服务器A的192.168.70.12上有抓到来自192.168.70.13寻找192.168.70.1的ARP，但是却没有成功找到的返回
有来自192.168.70.13的寻找192.168.70.1的icmp包，但只有request， no response found
然后通过如下方法解决，让主机B可以ping到192.168.70.1：
在主机B上添加到192.168.70.0/24网段的路由：
sudo route add -net 192.168.70.0/24 gw 192.168.70.12
在服务器A添加到主机B的路由：
sudo route add -host 192.168.70.13 gw 192.168.70.12
然后启动ueransim测试：
结论
无法启动，ueransim需要接入demo-oai等网桥，貌似无法接入另一台机器上的网桥。
但这样的网络配置可以作为非容器化ueransim的一种配置，中间不用换网段到192.168.12.x
解决思路2 docker-swarm
Docker Compose和Docker Swarm旨在实现完全集成，这意味着您可以将Compose应用程序指向Swarm集群，并使它们都像使用单个Docker主机一样正常工作。引用
manager是我们管理集群的入口，我们的docker命令都是在manager上执行，node节点上是不能执行dockr命令的
测试过程
这里我将服务器A作为管理节点，主机B作为工作节点
在服务器A上，通过ssh接入想作为管理节点的服务器，然后执行swarm init命令，指定swarm管理机的IP地址：
#安装docker-ce
sudo apt-get update
sudo apt-get install docker-ce
#指定为管理节点，该节点ip为192.168.12.3
lab@lab-virtual-machine:~$ docker swarm init --advertise-addr 192.168.12.3
出现以下提示
Swarm initialized: current node (uowf6o6oftuh47y2qjgm7jqeh) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-2f3q3ajwud8mg8xw62zbs7k0hpw9ypss7qgqcyjdzw5dns4qxf-a9mnk42uf9tjh58yj8s00t4ta 192.168.12.3:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
其中这里表示如何加入工作节点：
docker swarm join --token SWMTKN-1-2f3q3ajwud8mg8xw62zbs7k0hpw9ypss7qgqcyjdzw5dns4qxf-a9mnk42uf9tjh58yj8s00t4ta 192.168.12.3:2377
在主机B上将主机B设置为工作节点：
docker swarm join --token SWMTKN-1-2f3q3ajwud8mg8xw62zbs7k0hpw9ypss7qgqcyjdzw5dns4qxf-a9mnk42uf9tjh58yj8s00t4ta 192.168.12.3:2377
出现以下提示：
This node joined a swarm as a worker.
到此搭建了一个简单的swarm集群。
查看接入的节点：
lab@lab-virtual-machine:~$ docker node ls
查看创建的网络：
docker network ls
创建一个新网络：
网络模式需要选择overlay
docker network create -d overlay testnet
可是OAI核心网的网络模式是bridge，是否可以将其变成overlay？
将所有docker-compose-basic-vpp-nrf.yaml中的网络由bridge改为overlay：
networks:
public_net:
driver: overlay
name: demo-oai-public-net
ipam:
config:
- subnet: 192.168.70.0/24
driver_opts:
com.docker.network.bridge.name: "demo-oai"
public_net_access:
driver: overlay
name: oai-public-access
ipam:
config:
- subnet: 192.168.72.0/24
driver_opts:
com.docker.network.bridge.name: "cn5g-access"
public_net_core:
driver: overlay
name: oai-public-core
ipam:
config:
- subnet: 192.168.73.0/24
driver_opts:
com.docker.network.bridge.name: "cn5g-core"
然后使用docker stack启动
之前 swarm 集群中docker service create一次只能部署一个微服务，我们可以使用 docker stack + compose 一次启动多个服务
stack相关操作：
deploy Deploy a new stack or update an existing stack
ls List stacks
ps List the tasks in the stack
rm Remove one or more stacks
services List the services in the stack
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose$ docker stack deploy --compose-file docker-compose-basic-vpp-nrf.yaml oai
查看运行的服务：
docker service ls
查看容器运行状态：
docker service ps 容器名字
启动ueransim;
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose$ sudo docker stack deploy --compose-file docker-compose-ueransim-vpp.yaml ueransim
[sudo] password for lab:
WARN[0000] network public_net_access: network.external.name is deprecated in favor of network.name
WARN[0000] network public_net: network.external.name is deprecated in favor of network.name
Ignoring unsupported options: privileged
Ignoring deprecated options:
container_name: Setting the container name is not supported.
Error response from daemon: 2 matches found based on name: network demo-oai-public-net is ambiguous
其中前两个警告WARN【0000】是由于yaml文件网络external的格式不对，更改为如下后会消失：
networks:
public_net:
external: true
name: demo-oai-public-net
public_net_access:
external: true
name: oai-public-access
后面的警告Error response from daemon: 2 matches found based on name: network demo-oai-public-net is ambiguous是由于机器上docker network里的demo-oai-public-net有local与swarm两种
将其中local的部分删掉：
docker network rm f6dd0838cf68
docker network rm 34b108d99783
docker network rm f9b3e7f7b442
再次启动ueransim：
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose$ sudo docker stack deploy --compose-file docker-compose-ueransim-vpp.yaml ueransim
Ignoring unsupported options: privileged
Ignoring deprecated options:
container_name: Setting the container name is not supported.
Creating service ueransim_ueransim
但是查看ueransim的日志，发现未能启动成功：
甚至连gnb都没有成功接入OAI核心网

这样运行的容器乱七八糟的分布在多个机器上，需要通过如下方式指定不同容器运行的节点：
利用docker-compose.yml文件中的deploy.placement.constraints属性
#指定manage或worker
deploy:
replicas: 1
placement:
constraints:
## 常用方式指定 manager或者work节点
- node.role == worker
#指定主机名
deploy:
replicas: 1
placement:
constraints:
- node.hostname == docker1
指定标签的方法：
node label 可以给一个或多个机器打上一个标签，然后再compose文件中指定节点标签，就可以部署在打上对应标签的机器上。具体步骤如下：
现在主节点机器上对所有节点机器进行打标签操作，命令如下：
docker node update --label-add role=标签名称 主机名
例如我要对一个主机名为docker1的机器打上一个标签为db的标签
docker node update --label-add role=db docker1
deploy:
replicas: 1
placement:
constraints:
- node.labels.role == db
除此以外还有指定节点ID的方式
这里我采用指定manager与worker的方式：
将核心网部署在manager节点上，将ueransim部署在worker节点上

经过较长时间的等待后，启动结果如下：
核心网网元正常启动，ueransim未成功
对ueransim进行重启：
docker service ls
docker service update --force 07ms7mdsk907
重启后依旧无法接入
将ueransim与核心网都部署到服务器A上，依旧同样的报错
再尝试将所有容器全部部署到主机B上
依旧不行
通过设置容器依赖关系，让ueransim依赖与其他核心网网元，这样ueransim会在其他网元全部启动后才启动：

结论
使用docker swarm可以实现容器的分立部署，让一个系统的容器自定义的分配到不同的主机上运行，我创建的项目中成功启动了OAI核心网与ueransim容器，核心网可以正常运行，但无论是将ueransim和OAI核心网分配到多台主机上还是一台主机上，ueransim始终无法正常接入，且其内部的网络关系被隐藏了难以进行调试，使用docker swarm方法失败。
讨论： 原始方案路由关系详解
分立部署核心网和ueransim
原始方案实现了OAI在服务器A上的部署，ueransim在主机B上的部署，并且ueransim接入了核心网，创建了PDU session，生成了用户应用接口uesimtun0：12.1.1.x，并且在ueransim容器内部可以ping到核心网demo-oai：192.168.70.1及其他网元以及进行TCP客户端&服务器的通信，但在通过uesimtun0进行通信却不行。
在此我们先详细分析此方案的路由关系，网络连接关系，在探讨其中可能存在的问题及解决方法。

0422调试问题发现
1.ueransim 非容器分立部署可以接入建立PDU session与uesimtun0但无法通过nr-binder绑定12.1.1.x传输数据：
基站侧的路由添加既需要添加到192.168.70.0/24的也需要1添加192.168.72.0/24的，
分析：在mini的核心网中只需要添加到一个路由可能是该路由既承载了控制面也承载了用户面，而在basic的核心网中，70网段承载了控制面，只添加此路由也可以建立PDUsession，但无法传输用户面数据，再添加到72网段的路由就可以了
2.sudo sysctl net.ipv4.conf.all forwarding=1的意义
在核心网添加这个命令，开启的是路由转发，使容器网桥上的各个网元可以被访问到
具体体现为，开启了这个在基站可以ping到网元如amf：192.168.70.132， 而不开启就ping不到
0422 讨论：解决问题路径发现
经过测试，在分立部署情况下，使用非容器的ueransim可以成功接入核心网并传输数据，没有复杂的网桥间路由，只有在基站侧添加到核心网两个网桥的路由，可以成功接通。
在容器ueransim情况下，只添加两个这样的网桥基站也可以接入，但无法使用12.1.1.x传输数据，然后在核心网侧添加到60网桥的路由后也无法传输
于是想到：是否可以把容器当作虚拟机来使用，让容器可以直接直连网口ens40，这样也许就可以在容器内部添加两个路由，并在容器内部运行ueransim程序，然后如同在虚拟机中一样接入核心网并传输数据。
关键：物理网口直连容器（查询结果如下），在容器内部直接访问物理网口（无太多相关结果）
https://blog.csdn.net/fgf00/article/details/52575500
https://blog.csdn.net/smallfish1983/article/details/38820441
此办法是将容器默认网桥或自建网桥与物理网卡绑定在一起，已经尝试过应该不行

该文章写了两种方法，其一是端口映射，在创建容器时指定，使容器的中应用进程的端口暴露到宿主机上，外部网络对容器内部程序进行访问时只需要通过：宿主机IP+暴露端口号的方式进行访问 。
**Think：**如果是我用过的TCP客户端与服务器，我可以比较轻松的设置IP与端口号以及进行通信。但是ueransim这个程序如何的端口号如何获取？获取后对它进行访问可以进行怎样的操作？ 归根结底端口号是传输层的事情，而要想使ueransim不做更改的接入OAI核心网需要进行数据链路层的连接。
与之相似的是指定容器的网络模式为host，这样创建的容器直接使用主机的命名空间，访问容器中运行的应用程序就像访问在主机中运行的应用程序一样。
**这种可以试一下：**将容器ueransim设置为host模式，看是否能直接接入服务器A上的核心网。进一步，由于官方的ueransim启动程序的问题，可能不支持直接设置为host自动启动，可能需要构建自己的ueransim容器，然后将其设置为host。
0424，尝试docker网络模式host解决
方法简述
在分立部署情况下，使用非容器的ueransim可以成功接入核心网并传输数据，没有复杂的网桥间路由，只有在基站侧添加到核心网两个网桥的路由，可以成功接通。
在容器ueransim情况下，只添加两个这样的网桥基站也可以接入，但无法使用12.1.1.x传输数据，然后在核心网侧添加到60网桥的路由后也无法传输
于是想到：是否可以把容器当作虚拟机来使用，让容器可以直接直连网口ens40，这样也许就可以在容器内部添加两个路由，并在容器内部运行ueransim程序，然后如同在虚拟机中一样接入核心网并传输数据。
经过查询使用docker的host网络模式，让docker容器与主机公用一个网络命名空间，使ueransim容器内的网络与主机网络完全互通，就可以访问主机物理接口
测试过程
docker host
docker-compose host
服务器A上核心网部分启动：
sudo sysctl net.ipv4.conf.all.forwarding=1
sudo iptables -P FORWARD ACCEPT
docker-compose -f docker-compose-basic-vpp-nrf.yaml up -d
主机B上ueransim更改：
#添加主机B到服务器A核心网的路由
gNB-host$: sudo ip route add 192.168.70.0/24 via 192.168.12.3 dev ens40
gNB-host$: sudo ip route add 192.168.72.0/24 via 192.168.12.3 dev ens40

可以确定，此容器内部网络环境与在容器外一模一样，那么接下来先需要做的就是解决基站为何不能接入的问题：
#安装vim 用于编辑配置文件
apt-get update
apt-get install vim
基站与ue启动用代码：

启动ue：
/ueransim/bin/nr-ue -c /ueransim/etc/custom-ue.yaml
启动成功日志：
接下来进行一直没有成功的跨世界测试：
root@lab-virtual-machine:/ueransim/etc# ping -I 12.1.1.2 192.168.70.1
芜湖！卡了近一个月的问题到此成功解决！
下面我们再来测试下其他：
TCP通信测试：
将TCPclient.py脚本与ueransim配置文件放在同一文件夹下;
将TCPclient.py克隆到容器内部：
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose/ueransim yz$ sudo docker cp TCPclient.py 2082b5aa7971:/ueransim/bin
Successfully copied 2.56kB to 2082b5aa7971:/ueransim/bin
在服务器A的核心网启动TCPsever.py:
python3 TCPsever.py
TCPsever.py代码如下：
import socket
from threading import Thread
def new_client_connect(new_client_socket, client_ip_port):
while True:
# 收发数据
recv_data = new_client_socket.recv(1024)
if len(recv_data) != 0:
recv_text = recv_data.decode("gb2312")
print("接收到[%s]的信息：%s" % (str(client_ip_port), recv_text))
else:
print("客户端断开连接")
break
# # 关闭连接
# new_client_socket.close() # 表示断开与当前的客户端的通信
def main():
# 创建套接字
tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

在主机B基站测ueransim容器内启动TCPclient.py:
./nr-binder 12.1.1.2 python3 TCPclient.py
成功发送！！！
在服务器A核心网侧成功接收：
** 测试使用curl访问网页：**
#安装curl
root@lab-virtual-machine:/ueransim/bin# apt-get install curl
确保服务器A核心网侧网络连接正常可以访问百度
root@lab-virtual-machine:/ueransim/bin# ./nr-binder 12.1.1.2 curl www.baidu.com
最后几个重要的问题：
- 如何将这个容器变为一键启动式，而不需要接入容器内部
- 这样的容器是否可以生成多个运行，而不是像之前直接在虚拟机中只能运行一个
- 在主机上是否可以直接看到uesimtun0，ueranism安全性的问题
答案如下：
-
在主机上是否可以直接看到uesimtun0，ueranism安全性的问题？
是可以看见的：
容器内外网络完全一致 -
这样的容器是否可以生成多个运行，而不是像之前直接在虚拟机中只能运行一个
构建其他的ueransim：
新发现：之前在容器内部进行各种更改，对gnb以及ue的配置文件进行更改，其实只需要对ueransim的docke-compose配置文件进行进一步更改，就可以直接启动：
更改后的ueransim文件：

测试总结：生成两个容器，都健康，在核心网看见一个基站接入，两个ue接入，生成了两个uesimtun0接口，这些接口在容器内都可以使用，成功通过接口进行TCP传输，但是ifconfig发现明明是12.1.1.4和12.1.1.5，但在使用时却发现12.1.1.2与12.1.1.3还有12.1.1.4可以进行TCP传输，而12.1.1.5不行。
再次进行测试，使用这些接口绑定不同的端口号进行传输，之前是都绑定：192.168.70.1：8088进行传输，这次对不同的接口绑定不同的端口进行传输，验证不同应用传输的可行性：
在服务器A核心网侧创建两个TCPsever,两者的差别是端口号不一样：
TCPsever1.py：
import socket
from threading import Thread
def new_client_connect(new_client_socket, client_ip_port):
while True:
# 收发数据
recv_data = new_client_socket.recv(1024)
if len(recv_data) != 0:
recv_text = recv_data.decode("gb2312")
print("接收到[%s]的信息：%s" % (str(client_ip_port), recv_text))
else:
print("客户端断开连接")
break
# # 关闭连接
# new_client_socket.close() # 表示断开与当前的客户端的通信
def main():
# 创建套接字
tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 绑定端口和ip
tcp_server_socket.bind(("192.168.70.1", 8088))
# 设置套接字为被动监听模式，不能主动发送数据，128为允许接收的最大连接数
tcp_server_socket.listen(128)
while True:
# 接收客户端连接
new_client_socket, client_ip_port = tcp_server_socket.accept()
t1 = Thread(target=new_client_connect, args=(new_client_socket, client_ip_port))
t1.start()
# tcp_server_socket.close() # 表示不再接受新客户端的连接，已经连接的可以继续服务
if __name__ == '__main__':
main()
TCPsever2.py:
import socket
from threading import Thread
def new_client_connect(new_client_socket, client_ip_port):
while True:
# 收发数据
recv_data = new_client_socket.recv(1024)
if len(recv_data) != 0:
recv_text = recv_data.decode("gb2312")
print("接收到[%s]的信息：%s" % (str(client_ip_port), recv_text))
else:
print("客户端断开连接")
break
# # 关闭连接
# new_client_socket.close() # 表示断开与当前的客户端的通信
def main():
# 创建套接字
tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 绑定端口和ip
tcp_server_socket.bind(("192.168.70.1", 8087))
# 设置套接字为被动监听模式，不能主动发送数据，128为允许接收的最大连接数
tcp_server_socket.listen(128)
while True:
# 接收客户端连接
new_client_socket, client_ip_port = tcp_server_socket.accept()
t1 = Thread(target=new_client_connect, args=(new_client_socket, client_ip_port))
t1.start()
# tcp_server_socket.close() # 表示不再接受新客户端的连接，已经连接的可以继续服务
if __name__ == '__main__':
main()
同时运行这两个TCPsever：
python3 TCPserve1.py
python3 TCPserve2.py
然后在主机Bueransim侧的两个ueranism容器内分别绑定不同的uesimtun0，运行两个TCPclient:
TCPclient1：
import socket
import time
# 创建套接字
tcp_client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print("Waitting for connecting...")
# 建立连接
tcp_client_socket.connect(("192.168.70.1", 8088))
print("Connected!")
# 发送数据
print("Sending message...")
while 1:
tcp_client_socket.send("你好".encode("gb2312"))
time.sleep(5)
# 接收数据
recv_data = tcp_client_socket.recv(1024).decode("gb2312")
print(recv_data)
# 关闭套接字
tcp_client_socket.close()
TCPclient2：
import socket
import time
# 创建套接字
tcp_client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print("Waitting for connecting...")
# 建立连接
tcp_client_socket.connect(("192.168.70.1", 8087))
print("Connected!")
# 发送数据
print("Sending message...")
while 1:
tcp_client_socket.send("你好".encode("gb2312"))
time.sleep(5)
# 接收数据
recv_data = tcp_client_socket.recv(1024).decode("gb2312")
print(recv_data)
# 关闭套接字
tcp_client_socket.close()
分别复制到两个容器中：
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose/ueransim yz$sudo docker cp TCPclient1.py ueransim:/ueransim/bin
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose/ueransim yz$sudo docker cp TCPclient2.py ueransim2:/ueransim/bin
在两个容器中使用两个不同uesimtun接口绑定运行这两个TCPclient：
#在ueransim1容器内
root@lab-virtual-machine:/ueransim/bin# ./nr-binder 12.1.1.2 python3 TCPclient1.py
#在ueransim2容器内
root@lab-virtual-machine:/ueransim/bin# ./nr-binder 12.1.1.3 python3 TCPclient2.py
结果两个TCP服务都传输成功了！
服务1：
服务2：
到此，我们可以确定，用这种方式，至少可以在一个虚拟机中使用多个uesimtun接口进行多个业务的传输。
结论
使用host容器网络模式部署完成，可以实现单ueransim容器分立部署接入OAI核心网，并测试传输数据
问题提出：修改官方ueransim容器为自定义容器
最后一个问题：如何将这个容器变为一键启动式，而不需要接入容器内部
首先尝试基于已经构建完成的容器，能否使用docker commit命令，使其生成新的镜像：
ueransim2在运行时进行commit提交：
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose/ueransim yz$ docker container commit -a "@yinzhao" -m"add python3" ueransim2 ueransimyz2
WARNING: Error loading config file: /home/lab/.docker/config.json: open /home/lab/.docker/config.json: permission denied
sha256:f64be76d1d92b0785ee366b69ed6394e98c281e001e2282a1a017bb70269e535
生成了新的image：
使用该image构建docker-compose启动文件：
启动：
结果是这样直接commit提交的镜像是无法启动的，会直接退出
又到了这个老问题
ueransim容器自定义构建的方法探索
为了让ueransim无需每次启动都接入容器进行操作，在此探索可行的方法：
https://blog.csdn.net/a772304419/article/details/123199579
根据此博客所言，使用commite构建新镜像是会让镜像因为过多无关操作以及以往层级无法修改使镜像非常臃肿，且更改的内容是黑盒操作其他人无从得知进行了那些修改，即使是镜像生成者在一段时间后也可能忘掉，使维护变得非常困难。所以更推荐从dockerfile开始构建镜像。
如下是官方的ueransim+OAI教程，其中有两种方法使用ueransim镜像，其中第一种就是自己构建镜像的方法：
https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-fed/-/blob/master/docs/DEPLOY_SA5G_WITH_UERANSIM.md#6-getting-a-ueransim-docker-image
从官网clone代码到本地：
git clone -b docker_support https://github.com/orion-belt/UERANSIM.git
如果不行可以直接进入ueransim构建clone地址下载代码后复制到Ubuntu中
然后进入文件夹进行构建：
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose/ueransim yz/UERANSIM$ sudo docker build --target ueransim --tag ueransim:latest1 -f docker/Dockerfile.ubuntu.18.04 .
这里为与之前已存在的ueransim镜像进行区别，将进行tag由ueransim:latest改为了ueransim:latest1
构建非常消耗时间：
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose/ueransim yz/UERANSIM$ sudo docker build --target ueransim --tag ueransimyz:latestyz -f docker/Dockerfile.ubuntu.18.04 .

无法直接启动：
https://www.coder.work/article/7362041
https://bbs.csdn.net/topics/390847016 是关于这个报错的原因：入口点有问题
可以直接docker run运行容器：
lab@lab-virtual-machine:~/oai-cn5g-fed/docker-compose/ueransim yz$ sudo docker run -it ueransimyz:latestyz /bin/bash
检查dockerfile，对其进行修改：

构建镜像完成后镜像依旧无法正常使用docker-compose启动，使用docker run单独启动发现里面正常安装了vim 与python3
报错是 no command specified但明明启动接入了entrypoiny
