Docker Hub简单使用

Docker hub仓库使用

准备工作：

​ 起先，需要在https://hub.docker.com/注册一个用户

演示一次将镜像上传到docker hub的过程

pull一个镜像

首先需要一个镜像

[root@localhost ~]# docker pull benyoo/alpine:3.4.20160812  
3.4.20160812: Pulling from benyoo/alpine

e110a4a17941: Already exists 
Digest: sha256:41250fea2bc5dfdc204d54e4d2108aae7a452876bed359ae277983aea4ae3e02
Status: Downloaded newer image for benyoo/alpine:3.4.20160812

将镜像run起来

[root@localhost ~]# docker run --name myalpine -it benyoo/alpine:3.4.20160812 /bin/bash
bash-4.3# exit

commit

现在我将容器commit

[root@gitlab nginx]# docker commit -m "v1" f8ac81a9f98c marksugar/nginx:8.30
sha256:e50a274c5823651858d56763d02e2cd843006a61f9ff3f97535eb7dd8d17db2f
[root@gitlab nginx]# docker images
REPOSITORY                TAG                 IMAGE ID            CREATED             SIZE
marksugar/nginx           8.30                e50a274c5823        6 seconds ago       13.77 MB

登录docker hub

commit完成后，先登录

[root@localhost ~]# 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.

commit完成后在images中会出现一个新的

[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

开始上传

开始push

[root@localhost ~]# docker push marksugar/alpine
The push refers to a repository [docker.io/marksugar/alpine]
dbe4e1a4c160: Pushed 
93d40cd73394: Mounted from marksugar/nginx 
4fe15f8d0ae6: Mounted from marksugar/nginx 
latest: digest: sha256:5ae1b32053247f3d251fe5ee56aa817d330cb007603272985a0aab0b79a4c9b3 size: 946
[root@localhost ~]# 

上传完成后在docker hub中会出现一个marksugar/alpine，现在将他pull下来

[root@gitlab conf]# docker pull marksugar/alpine
Using default tag: latest
latest: Pulling from marksugar/alpine

e110a4a17941: Already exists 
92c6475c18dd: Pull complete

Status: Downloaded newer image for marksugar/alpine:latest

在查看marksugar/alpine

[root@gitlab conf]# docker images
