二.docker镜像基本命令



 

1. 获取镜像:

   docker pull cenos

1. 查看镜像：

   [root@bogon ~]# docker images

   REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

   centos              latest              d83a55af4e75        8 days ago          196.7 MB

2. 为docker镜像添加新标签

   [root@bogon ~]# docker tag centos:latest cenos:later

   [root@bogon ~]# docker images

   REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

   centos              latest              d83a55af4e75        8 days ago          196.7 MB

   cenos               later               d83a55af4e75        8 days ago          196.7 MB

3. 获取镜像的详细信息：

   [root@bogon ~]# docker inspect d83a55af4e75

   [

   {

       "Id": "d83a55af4e75f89d589940a008e1f8d87329fed8e88b17519b07bafee796e0c7",

       "Parent": "3fbd5972aaac8678641224de872b186ee11e8da3bfec293715b256e1ab4db14e",

       "Comment": "",

       "Created": "2016-07-29T20:59:10.01570692Z",

       "Container": "53ef97a96c409a033e214be92d67d0682ecace7ae5155c647a80aea20fb8e375",

4. 查询指定信息

   [root@bogon ~]# docker inspect -f {{.Architecture}} d83a55af4e75

   amd64

5. 搜寻镜像

   [root@bogon ~]# docker search mysql

   NAME                    DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED

   mysql                   MySQL is a widely used, open-source relati...   2801      [OK]       

   mariadb                 MariaDB is a community-developed fork of M...   787       [OK]       

    

   7.使用镜像ID删除镜像

   [root@bogon ~]# docker rmi d83a55af4e75

   Untagged: centos:latest

   Deleted: d83a55af4e75f89d589940a008e1f8d87329fed8e88b17519b07bafee796e0c7

   Deleted: 3fbd5972aaac8678641224de872b186ee11e8da3bfec293715b256e1ab4db14e

   Deleted: b200b2d33d98732d2487f455e0851f2cb09dfae28fd3055ea6d401ff9e8df3da

   Deleted: 3690474eb5b4b26fdfbd89c6e159e8cc376ca76ef48032a30fa6aafd56337880

1. docker创建第一个容器：

   [root@bogon ~]# docker run centos echo 'hello world'

   hello world

2. 查看机器上的所有容器

   root@bogon ~]# docker ps -a

   CONTAINER ID        IMAGE               COMMAND                CREATED             STATUS                      PORTS               NAMES

   98790c7a70e0        centos              "echo 'hello world'"   26 seconds ago      Exited (0) 24 seconds ago                       cranky_darwin

    

3. 强行删除镜像

   Docker rmi -f centod

4. 创建镜像

1. 基于已有镜像的容器创建

   a启动一个镜像进行一些修改操作，退出

   [root@bogon ~]# docker run -ti centos:latest /bin/bash

   [root@5f3e0f1a69bb /]# touch test

   [root@5f3e0f1a69bb /]# exit

   Exit

   b.提交镜像

   [root@bogon ~]# docker commit -m "ADdd a new file" -a  "Docker Newbee"  5f3e0f1a69bb  test

   1d7be5e364c1fa25f686543fa2c0df507c039c0d46ac4d7501a6955307b5ee3a

   [root@bogon ~]# docker images

   REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

   test                latest              1d7be5e364c1        14 seconds ago      196.7 MB

   centos              latest              d83a55af4e75        8 days ago          196.7 MB

    

2. 基于本地模板导入

   [root@bogon Desktop]# cat MySQL-python-1.2.2.tar.gz  | docker import -  mysqlpython:1.2.2

   6455db1ee110d30e0dffe0f875778e65c317510b4e98453281b7e29aab476421

    

3. 基于dockerfile创建

1. 存入存出镜像

1. 存出镜像

   [root@bogon Desktop]# docker images

   REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

   mysqlpython         1.2.2               6455db1ee110        3 minutes ago       323.2 kB

   cenos               1.2.2               8805a9541c19        3 minutes ago       323.2 kB

   test                latest              1d7be5e364c1        17 minutes ago      196.7 MB

   centos              latest              d83a55af4e75        8 days ago          196.7 MB

   [root@bogon Desktop]# docker save -o mysql-python_1.2.2  mysqlpython:1.2.2

   [root@bogon Desktop]# ls

   mysql-python_1.2.2  MySQL-python-1.2.2.tar.gz  python

    

2. 载入镜像

   [root@bogon Desktop]# docker load < mysql-latest.tar.xz

   或者[root@bogon Desktop]# docker load --input mysql-latest.tar.xz

   13.上传镜像

   docker push user/test:latest(user用户需要在dockerHub网站注册)
