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

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
