urlpatterns = [
path("", views.index),
]
或
def index(request):
context = {}
return render(request, "index.html", context)
```
**confidential_containers内的urls.py文件**
```
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path("", include("app.urls")),
#path("app/", include("app.urls")), 需要127.0.0.1:8000/app
path("admin/", admin.site.urls),
]
```
# 3、ssh连接虚拟机
**下载paramiko**
`pip install paramiko`
**app内的views.py中添加**
```python
def index(request):
host = '192.168.89.134'
port = 22
username = 'root'
password = '123456'
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(host, port, username, password)
command = """
kubectl get pod -A
"""
stdin, stdout, stderr = ssh.exec_command(command)
output_lines = stdout.readlines() #读行
output_split = [line.split() for line in output_lines] #按空格隔开
first = output_split[:1]
second = output_split[1:]
#output = ''.join(output_lines) # 将列表转换为字符串
# output = stdout.read().decode('utf-8')
error = stderr.read().decode('utf-8')
ssh.close()
context = {'first': first, 'second':second, 'error': error}
return render(request, "index.html", context)
```

**POD启动状态一直为ContainerCreating，提示cni0的IP与既有子网不同
报错信息**
使用 kubectl describe pods <pod-name> -n <namespace> 命令可看到提示信息
Failed to create pod sandbox: rpc error: code = Unknown desc = failed to setup network for sandbox “745720ffb20646054a167560299b19bb9ae046fe6c677b5d26312b89a26554e1”: failed to set bridge addr: “cni0” already has an IP address different from 172.20.2.1/24
进入到对应计算节点，使用ip a命令确认cni0的IP信息，使用cat /run/flannel/subnet.env查看flannel网络插件分配的子网IP，发现两者确实不一致。
解决办法
删掉这个IP错误的网卡cni0, 之后flanneld自动重新创建。命令如下。
```
ifconfig cni0 down
ip link delete cni0
```
**压缩与解压缩**
