修改已有官方镜像
注意：记住容器的 ID，稍后还会用到 docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 8511226ff1da 8e022c70c28b 使用 docker commit 命令来提交更新后的副本。 4f177bd27a9ff0f6dc2a830403925b5360bfe0b93d476f7fc3231110e7f71b1c^C root@myxps:~# docker commit -m "Added curl vim.tiny" -a "linuxsa.org" 8511226ff1da evan886/debian:v1 #是不是这个添加了后面的不用添加tag呢 下次 再试一下 sha256:9c19bdca07aa14194e93f65264ad42f18dbabc43a8bb6bc3eadd7790a67f2296 root@myxps:~# 其中，-m 来指定提交的说明信息，跟我们使用的版本控制工具一样；-a 可以指定更新的用户信息；之后是用来创建镜像的容器的 ID；最后指定目标镜像的仓库名和 tag 信息。创建成功后会返回这个镜像的 ID 信息。 使用 docker images 来查看新创建的镜像。 root@myxps:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE <none> <none> 9c19bdca07aa 26 seconds ago 118MB debian buster-slim 8e022c70c28b 11 days ago 69.2MB root@myxps:~# 使用 docker images 来查看新创建的镜像。 root@myxps:~# docker run -it 9c19bdca07aa bash 打上自己的tag root@myxps:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE <none> <none> 9c19bdca07aa 4 minutes ago 118MB debian buster-slim 8e022c70c28b 11 days ago 69.2MB root@myxps:~# docker tag 9c19bdca07aa evan886/debian:v1 root@myxps:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE evan886/debian v1 9c19bdca07aa 9 minutes ago 118MB debian buster-slim 8e022c70c28b 11 days ago 69.2MB root@myxps:~# root@myxps:~# docker login docker push evan886/debian:v1
利用 Dockerfile 来创建镜像
docker build --tag evan886/centos-nginx:v1 -f nginx/Dockerfile . docker run --name nginx -p 80:80 -v /data/apps/nginx/html/:/data/apps/nginx/html/ -d -it 9a4ccef0484d 登入容器： docker exec -it jenkins /bin/bash docker push evan886/centos-nginx:v1
