DockerSwarm+Dubbo镜像与部署相关命令与参数

Docker 镜像

一、容器转镜像

docker commit <containerId> <image:tag>
docker commit 3ffa4284ddca zookeeper:3.4.14

二、镜像保存文件

docker save zookeeper:3.4.14 > zookeeper_3.4.14.tar.gz

三、Dockerfile参考

FROM openjdk:8-jre
MAINTAINER songxz
WORKDIR /appADD ./ /app/ENV JAVA_OPTS "-Xms400m -Xmx3g"ENV spring.profiles.active prod
ENV file.encoding UTF-8EXPOSE 8089EXPOSE 20889RUN chmod 777 /app/start.shENTRYPOINT ["/app/start.sh"]

四、Dockerfile编译镜像

docker build -f ./Dockerfile -t 127.0.0.1:2000/web:v20190416184152
docker push 127.0.0.1:2000/web:v20190416184152

五、运行镜像

docker run -t -d --name="web" -p 8085:8085 -p 20885:20885 -e "DUBBO_IP_TO_REGISTRY=127.0.0.1" -e "DUBBO_PORT_TO_REGISTRY=20885"  -e "DUBBO_PORT_TO_BIND=20885" 127.0.0.1:2000/web:v20190416184152

六、Stack

version: '3.1'
services:
  vpcs:
    image: 127.0.0.1:2000/web:v20190416184152 
    deploy:
      replicas: 5
      resources:
        limits: 
          cpus: "1"
          memory: 8G
      restart_policy:
        condition: on-failure
      placement:
        constraints:
          - node.labels.usage==web_vpc
    ports:
      - 8085:8085
      - 20885:20885
    environment:
      DUBBO_IP_TO_REGISTRY: 127.0.0.1
      DUBBO_PORT_TO_REGISTRY: 20885
      DUBBO_PORT_TO_BIND: 20885

 

七、镜像打标签

docker tag web:v20190416184152 127.0.0.1:2000/web:v20190416184152

八、镜像推送

docker push 127.0.0.1:2000/web:v20190416184152
