healthcheck用于检测 docker 服务是否健康运行 。
healthcheck:test: ["CMD", "curl", "-f", "http://localhost"] # 设置检测程序interval: 1m30s# 设置检测间隔timeout: 10s # 设置检测超时时间retries: 3 # 设置重试次数start_period: 40s # 启动后，多少秒开始启动检测程序image指定容器运行的镜像
image: redis:5labels设置容器标签
labels:com.example.description: "Accounting webapp"com.example.department: "Finance"labels:- "com.example.description=Accounting webapp"- "com.example.department=Finance"links连接到另一个容器的网络，简单将就是让容器相互连通
web:links:- db- db:database- redislogging服务的日志记录配置，driver：指定服务容器的日志记录驱动程序，默认值为json-file 。有以下三个选项
driver: "json-file"driver: "syslog"driver: "none"仅在 json-file 驱动程序下，可以使用以下参数，限制日志得数量和大小 。
logging:driver: json-fileoptions:max-size: "200k" # 单个文件大小为200kmax-file: "10" # 最多10个文件syslog 驱动程序下，可以使用 syslog-address 指定日志接收地址 。
logging:driver: syslogoptions:syslog-address: "tcp://192.168.0.42:123"network_mode设置网络模式，格式如下：
network_mode: "bridge" #桥接模式network_mode: "host"network_mode: "none"network_mode: "service:[service name]"networks配置容器连接的网络
