docker常用镜像命令总结，包含将docker镜像推送到dockerhub,全程无废话

01.查看镜像 docker images

[root@i-rbj0ryi8 ~]$ docker images
REPOSITORY      TAG          IMAGE ID       CREATED         SIZE
rabbitmq        management   813865544c51   6 months ago    253MB
redis           latest       bc8d70f9ef6c   12 months ago   105MB

02.搜索镜像 docker search 镜像名

[root@i-rbj0ryi8 ~]$ docker search mysql #这里是查找mysql镜像，还可以指定镜像版本，如：docker search mysql5.7
NAME                           DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED
mysql                          MySQL is a widely used, open-source relation…   12556     [OK]              [OK]
# ......

03.下载镜像 docker pull 镜像名（若不指定镜像版本，默认会下载最新版）

[root@i-rbj0ryi8 ~]$ docker pull nginx:1.18.0
1.18.0: Pulling from library/nginx
f7ec5a41d630: Pull complete 
# ......

04.删除镜像 docker rmi 镜像id

[root@i-rbj0ryi8 ~]$ docker rmi 605c77e624dd #605c77e624dd为镜像id
Untagged: nginx:latest
Untagged: nginx@sha256:0d17b565c37bcbd895e9d92315a05c1c3c9a29f762b011a10c54a66cd53c9b31
Deleted: sha256:605c77e624ddb75e6110f997c58876baa13f8754486b461117934b24a9dc3a85
#......

04.提交镜像docker commit

[root@i-rbj0ryi8 ~]$ docker commit --help
Usage:  docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]
Create a new image from a container's changes
Options:
  -a, --author string    Author (e.g., "John Hannibal Smith <hannibal@a-team.com>")
  -c, --change list      Apply Dockerfile instruction to the created image
  -m, --message string   Commit message
  -p, --pause            Pause container during commit (default true)

具体使用

[root@i-rbj0ryi8 ~]$ docker commit -a "mhzzj" -m "提交测试" 5826c3e8ae24  testnginxv1.0  #7c324703d35a为提交的镜像id 
sha256:234b8472f14bcaf3ec3548ae45b23c0c00d850ea5dc7e9960c63b71f0e05af25

[root@i-rbj0ryi8 ~]$ docker images  
REPOSITORY      TAG          IMAGE ID       CREATED         SIZE
testnginxv1.0   latest       296b0b6f698d   3 minutes ago   182MB  #testnginxv1.0 为刚才提交的镜像 

[root@i-rbj0ryi8 ~]$ docker run -d -p 80:80 testnginxv1.0  #通过提交的镜像启动容器
e85dcdf5f7d2870d9f6724bdf0ca15c8f0a2a0ce26716e6627cfdca430d14732

05.镜像持久化docker save

[root@i-rbj0ryi8 ~]$ docker save -o savedemo.tar testnginxv1.0
[root@i-rbj0ryi8 ~]$ ls
savedemo.tar    #savedemo.tar 就是testnginxv1.0镜像持久化的数据

# 别的机器加载这个镜像
[root@i-rbj0ryi8 ~]$ docker load -i savedemo.tar
Loaded image: testnginxv1.0:latest

06.镜像推送docker push

1. 先注册dockerhub： https://login.docker.com/u/login/

2. 并且创建仓库

   ​

3. 登录docker

   [root@i-rbj0ryi8 ~]$ docker login
   Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
   Username: mhzzj
   Password: 
   WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
   Configure a credential helper to remove this warning. See
   https://docs.docker.com/engine/reference/commandline/login/#credentials-store
   
   Login Succeeded
   

4. 推送镜像

   [root@i-rbj0ryi8 ~]$ docker push mhzzj/pushdemo:testnginxv1.0
   The push refers to repository [docker.io/mhzzj/pushdemo]
   An image does not exist locally with the tag: mhzzj/pushdemo
   

   报错：原因：没有给镜像打标签

   打标签

   [root@i-rbj0ryi8 ~]$ docker tag testnginxv1.0 mhzzj/pushdemo:mytagv1.0
   [root@i-rbj0ryi8 ~]$ docker images
   REPOSITORY       TAG         IMAGE ID       CREATED         SIZE
   testnginxv1.0    latest      3b490214c1e9   8 minutes ago   133MB
   mhzzj/pushdemo   mytagv1.0   3b490214c1e9   8 minutes ago   133MB
   nginx            1.18.0      c2c45d506085   14 months ago   133MB
   

   推送

   [root@i-rbj0ryi8 ~]$ docker push mhzzj/pushdemo:mytagv1.0
   The push refers to repository [docker.io/mhzzj/pushdemo]
   53faf37c6825: Pushed 
   4fa6704c8474: Mounted from library/nginx 
   4fe7d87c8e14: Mounted from library/nginx 
   6fcbf7acaafd: Mounted from library/nginx 
   f3fdf88f1cb7: Mounted from library/nginx

   推送成功

   
   5. 下载推送的镜像

   [root@i-rbj0ryi8 ~]$ docker pull mhzzj/pushdemo:mytagv1.0
