docker与jenkins学习

docker命令：

docker create <image-id>
docker start <container-id>
docker run <image-id> = docker create <image-id> + docker start <container-id>
docker ps
docker ps -a
docker images
docker images –a
docker stop <container-id>
docker kill <container-id>
docker pause <container-id>
docker rm <container-id>
docker rmi <image-id>
docker commit <container-id>
docker build
docker exec <running-container-id>
docker inspect <container-id> or <image-id>
docker save <image-id>
docker export <container-id>
docker history <image-id>
