官当

1.compose模板文件组成 ​

顶级层次，由6部分组成

1.1 version ​

填写版本号，一般不用写

1.2 services ​

定义服务名字

1.3 networks ​

定义网络

1.4 volumes ​

定义存储

1.5 configs ​

1.6 secrets ​

2. compose语法 ​

用空格来控制格式，空出3个空格

2.1 services ​

官当

image ​

yaml
services:
  web:
    image: hello-world
services:
  web:
    image: hello-world

在 services 标签下的第二级标签是 web，这个名字是用户自己自定义，它就是服务名称。 image 则是指定服务的镜像名称或镜像 ID。如果镜像在本地不存在，Compose 将会尝试拉取这个镜像

container_name ​

yaml
services:
  web:
    image: hello-world
    container_name: vector
services:
  web:
    image: hello-world
    container_name: vector

hostname ​

yaml
services:
  web:
    image: hello-world
    container_name: vector
    hostname: vector
services:
  web:
    image: hello-world
    container_name: vector
    hostname: vector

restart ​

描述：启动策略

restart defines the policy that the platform applies on container termination.

  • no: The default restart policy. It does not restart the container under any circumstances.
  • always: The policy always restarts the container until its removal.
  • on-failure[:max-retries]: The policy restarts the container if the exit code indicates an error. Optionally, limit the number of restart retries the Docker daemon attempts.
  • unless-stopped: The policy restarts the container irrespective of the exit code but stops restarting when the service is stopped or removed.
yaml
services:
  web:
    image: hello-world
    container_name: vector
    hostname: vector
    restart: always
services:
  web:
    image: hello-world
    container_name: vector
    hostname: vector
    restart: always

ports ​

描述：启动映射外部端口

yaml
services:
  web:
    image: hello-world
    container_name: vector
    hostname: vector
    restart: always
    ports:
      - 8686:8686
services:
  web:
    image: hello-world
    container_name: vector
    hostname: vector
    restart: always
    ports:
      - 8686:8686

ports 其它写法

yaml
ports:
  - "3000"
  - "3000-3005"
  - "8000:8000"
  - "9090-9091:8080-8081"
  - "49100:22"
  - "8000-9000:80"
  - "127.0.0.1:8001:8001"
  - "127.0.0.1:5000-5010:5000-5010"
  - "6060:6060/udp"
ports:
  - "3000"
  - "3000-3005"
  - "8000:8000"
  - "9090-9091:8080-8081"
  - "49100:22"
  - "8000-9000:80"
  - "127.0.0.1:8001:8001"
  - "127.0.0.1:5000-5010:5000-5010"
  - "6060:6060/udp"

volumes ​

yaml
services:
  web:
    image: hello-world
    container_name: vector
    hostname: vector
    restart: always
    ports:
      - 8686:8686
    volumes:
      - /var/log/nginx:/nginx_logs  # 这是需要采集的日志的路径需要挂载到容器内
services:
  web:
    image: hello-world
    container_name: vector
    hostname: vector
    restart: always
    ports:
      - 8686:8686
    volumes:
      - /var/log/nginx:/nginx_logs  # 这是需要采集的日志的路径需要挂载到容器内
