下载基础镜像

docker pull nginx

查看镜像

docker images

打包镜像

# -o 或 > 指定输出镜像文件的包名nginx.tar  nginx  镜像名
docker save -o nginx.tar nginx  
   或    
docker save > nginx.tar nginx  

上传云服务器(略)

解压镜像

docker load < nginx.tar
    或
docker load -i nginx.tar

解压完成后会在docker images 下生成一个对应的nginx镜像

上传云服务器镜像空间

1. 登陆对应的hub空间docker login xxxxx
2. 上传解压好的镜像 docker push xxxxx/nginx:v1
3. 创建一个nginx目录mkdir nginx
4. 打包需要的文件

5. 编写dockerfile文件vi Dockerfile

FROM xxxx/nginx:v1
MAINTAINER lisongyu <li.songyu@qq.com>
USER root
WORKDIR /etc/nginx/conf.d/
EXPOSE 80
ADD ./nies-ui/ /usr/share/nginx/html/nies-ui/
ADD nies.conf /etc/nginx/conf.d/
ADD ./key ./key

6. 编写生成上传镜像脚本vi docker.sh

docker build -t xxxxx/nginx:1234 . # “.” 记得不要丢
docker push xxxxx/nginx:1234

7. 给docker.sh附权并执行chmod +x docker.sh; ./docker.sh

   由于我在本地,不需要上传到hub,所以我这边用nginx:1234来代替实际的远程仓库xxxxx/nginx:1234

   

8. yaml配置文件编写vi nginx.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  namespace: default
  labels:
    app-name: nginx
spec:
  replicas: 1 # 设置启动的节点数
  selector:
    matchLabels:
      app-name: nginx
  template:
    metadata:
      labels:
        app-name: nginx
    spec:
      nodeSelector:
      securityContext:
        fsGroup: 1000 
        runAsUser: 0
      containers:
      - name: nginx
        image: xxxx/nginx:1234
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80  # 容器内部端口
          name: web
          protocol: TCP

---

apiVersion: v1
kind: Service
metadata:
  name: nginx
  namespace: default
  labels:
    app-name: nginx
  annotations:
    prometheus.io/scrape: 'true'

spec:
  selector:
    app-name: nginx
  ports:
  - name: nginx
    port: 80  # 容器内部端口
    targetPort: 80  # 容器内部端口
    nodePort: 30210  # nodePort k8s默认规定30000以上,节点机上默认访问的端口
  type: NodePort

8. 启动容器

kubectl replace --force -f nginx.yaml

9. 查看容器是否启动成功

kubectl get pods -n default

11. 查看日志并访问

kubectl logs -f nginx-6fddf6d666-fm5mc
