一、安装k8s Python客户端库,加载配置文件

pip install kubernetes

加载配置文件，引用模块等（config_file="path/to/config"是k8s的授权文件用于访问k8s）

from kubernetes import config
config.load_kube_config()
from kubernetes import config
config.load_kube_config(config_file="path/to/config")

二、创建API实例,访问api

import kubernetes
from kubernetes import client,config
config.kube_config.load_kube_config(config_file='G:\config')
v1 = client.CoreV1Api()#获取CoreV1API版本对象(创建API实例)

#列出类k8s中的所有名称空间

for namespace in v1.list_namespace().items:
    print(namespace.metadata.name)

#列举所有名称空间下的所有service

services=v1.list_service_for_all_namespaces()
for svc in services.items:
    print('%s \t%s \t%s \t%s \n' %(svc.metadata.namespace,svc.metadata.name,svc.spec.cluster_ip,svc.spec.ports))

#列举所有名称空间下的pod资源

pods=v1.list_pod_for_all_namespaces()
for i in pods.items:
    print("%s\t%s\t%s" %(i.status.pod_ip,i.metadata.namespace,i.metadata.name))

三、创建deployment和pod

from os import path
import yaml
from kubernetes import client,config
def main():
    config.load_kube_config(config_file='D:\config')
    with open(path.join(path.dirname(__file__),"nginx-deploy.yaml")) as f:
        dep=yaml.safe_load(f)
        k8s_apps_v1=client.AppsV1Api()
        resp=k8s_apps_v1.create_namespaced_deployment(body=dep,namespace='default')
        print('Deployment created,status=%s'%(resp.metadata.name))
if  __name__ == '__main__':
    main()

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.14.2
        ports:
        - containerPort: 80

#创建pod

from kubernetes import client, config

config.load_kube_config(config_file='D:\config')

v1 = client.CoreV1Api()
api_instance = client.CoreV1Api()

namespace = 'default'

# 创建 Pod
pod_manifest = {
    'apiVersion': 'v1',
    'kind': 'Pod',
    'metadata': {
        'name': 'mypod'
    },
    'spec': {
        'containers': [{
            'name': 'mycontainer',
            'image': 'nginx:latest',
            'ports': [{
                'containerPort': 80,
                'hostPort': 80
            }]
        }]
    }
}
resp = v1.create_namespaced_pod(body=pod_manifest, namespace=namespace)
print("Pod created. status='%s'" % resp.status.phase)

# 创建 Service
service_manifest = {
    'apiVersion': 'v1',
    'kind': 'Service',
    'metadata': {
        'name': 'myservice'
    },
    'spec': {
        'selector': {
            'app': 'myapp'
        },
        'ports': [{
            'protocol': 'TCP',
            'port': 80,
            'targetPort': 80,
            'nodePort': 30001
        }],
        'type': 'NodePort'
    }
}
resp = api_instance.create_namespaced_service(
    body=service_manifest,
    namespace=namespace)
print("Service created. status='%s'" % resp)

四、删除和修改pod

from os import path
import yaml
from kubernetes import client,config

def main():
    config.load_kube_config(config_file='G:\config')
    k8s_core_v1=client.CoreV1Api()
    resp=k8s_core_v1.delete_namespaced_pod(namespace='default',name='busybox-test')
    print('delete pod')
main()

from os import path
import yaml
from kubernetes import client,config
def main():
    config.load_kube_config(config_file='G:\config')
    k8s_core_v1=client.CoreV1Api()
    old_resp=k8s_core_v1.read_namespaced_pod(namespace='default',name='busybox-test')
    old_resp.spec.containers[0].image='nginx'
    #修改镜像
    new_resp=k8s_core_v1.patch_namespaced_pod(namespace='default',name='busybox-test',body=old_resp)
    print(new_resp.spec.containers[0].image)
if __name__=='__main__':
    main()
