Simple use of docker
Query Mirror
docker search centos7
query results are as follows
Download image
docker pull ansible/centos7-ansible
Run-time image
docker run -ti ansible/centos7-ansible
Modify the default image
Cd into the mirror to the root directory, create a folder app
cd /
mkdir app
Exit Mirror
exit
Query mirror (to modify the exit status of the mirror) just ran
docker ps -l
Suppose the query to the image id is: 5a9e468a19f6
Id just run to get an increase of TAG saved locally
Just run the query details mirroring:
检查运行中的镜像
$docker inspect 5a9e468a19f6
Assuming docker ps query to the id of 5a9e468a19f6
parameters: -l final
-a run through all of
it:
docker commit 5a9e468a19f6 rebornchang/centos7:v2
At this point the query will be more local docker mirror found out rebornchang / centos7 version v2
查询命令
docker images
Their modified docker docker image upload to your warehouse
First register their docker club account
Registered Address: https://cloud.docker.com/
Creating a warehouse
For example bloggers registered account name is rebornchang, created a repository called centos7, open.
After creating a warehouse execute commands on the host of the installation docker:
查看镜像：
docker images
End view mirror as shown below:
can see there are a REPOSITORY: rebornchang / centos7, TAG and v4 is.
At this point we log docker warehouse;
docker login
然后对应输入账号密码。就将docker远程账号和本地关联起来了
You can also modify the tag specified mirroring
$docker tag rebornchang/centos7:v4 rebornchang/centos7:latest
Sometimes the mirror is REPOSITORY and TAG, found the mirror ID is assumed to be 1a2w3e4r can use this command to modify
$docker tag 1a2w3e4r rebornchang/centos7:latest
Note: mirrored REPOSITORY name is the name of a remote repository docker, Tag is equivalent to a stand-alone version of the label, Tag do the same.
Upload local mirroring to a remote warehouse
docker push rebornchang/centos7:v4
The push refers to repository [docker.io/rebornchang/centos7]

This time on a web page query the remote repository you can see the push over the mirrored:
PS: This article will first come here, follow-up will update the build environment they need in the mirror.
PPS: bloggers this article before half Mao blogger sent me, I brought directly made, Who hair bloggers say so I said I docker's blog yet.
