私有仓库registry

1. registry的使用
2. 数据卷容器
3. 端口映射
4. 容器互连（使用centos镜像）

1. registry的使用

[root@localhost ~]# docker pull registry    ###私有仓库的核心，下载registry
Using default tag: latest 
latest: Pulling from library/registry
cbdbe7a5bc2a: Pull complete 
47112e65547d: Pull complete 
46bcb632e506: Pull complete

Digest: sha256:8be26f81ffea54106bae012c6f349df70f4d5e7e2ec01b143c46e2c03b9e551d
Status: Downloaded newer image for registry:latest
docker.io/library/registry:latest

root@localhost ~]# vim /etc/docker/daemon.json 
{
  "insecure-registries":["20.0.0.16:5000"],   ##安全的镜像仓库
  "registry-mirrors": ["https://b8l5tyyk.mirror.aliyuncs.com"]

[root@localhost ~]# systemctl restart docker.service   ##重启docker
[root@localhost ~]# docker create -it registry /bin/bash  ##创建容器
a4e2837e9c90930d53097f3e52076933f00dc97262707fc9b481359324d91abd

宿主机/data/registry自动创建挂载容器中的/tmp/registry
[root@localhost ~]# docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry
6e945d62df08f8976e707a1589f9d0b2399a912beb5d9f39cb53e5cf4ec2f786

更改标签为20.0.0.16:5000/nginx
[root@localhost data]# docker tag nginx:new 20.0.0.16:5000/nginx-nj

上传
[root@localhost data]# docker push 20.0.0.16:5000/nginx-nj
The push refers to repository [20.0.0.16:5000/nginx-nj]
f584d46bdf05: Pushed 
0786e5de7b4c: Pushed 
bf554cd3f1f1: Pushed 
f22d74eaee8b: Pushed 
8c126a222ddc: Pushed 
9549a5fbf038: Pushed 
449b6df4f317: Pushed 
af0fc267d0b3: Pushed

latest: digest: sha256:0ba5141b943bbc8966d4420698516a9c03f7e97d332e99bb36ed0a0f65f92bc1 size: 2205

获得私有仓库列表
[root@localhost data]#  curl -XGET http://20.0.0.16:5000/v2/_catalog
{"repositories":["nginx-nj"]} ##显示上传成功

测试私有仓库下载
 [root@localhost data]# docker pull 20.0.0.16:5000/nginx-nj

2. 数据卷容器

[root@localhost ~]# docker run --name web100 -v /data1 -v /data2 -it centos /bin/bash
[root@4df501c032b4 /]# ls
bin    dev   lib  media proc  sbin  tmp
data1  etc   lib64  mnt root  srv   usr
data2  home  lost+found  opt run   sys   var
[root@4df501c032b4 /]# cd data1
[root@4df501c032b4 data1]# touch 12.txt
[root@4df501c032b4 data1]# cd /data2
[root@4df501c032b4 data2]# touch 32.txt
[root@4df501c032b4 data2]# ls 
32.txt
新容器挂载数据卷容器web100
[root@localhost ~]# docker run -it --volumes-from web100 --name web12 centos /bin/bash
[root@558f16e01ae1 /]# ls 
bin    dev   lib  media proc  sbin  tmp
data1  etc   lib64  mnt root  srv   usr
data2  home  lost+found  opt run   sys   var
[root@558f16e01ae1 /]# cd data1
[root@558f16e01ae1 data1]# ls
12.txt

3. 端口映射

docker run -d -P httpd:centos
docker run -d -p 32768:80 httpd:centos
docker ps -a

4. 容器互连（使用centos镜像）

[root@localhost ~]# 、run -itd --name web11 centos:7 /bin/bash  ##创建并运行容器取名web1，端口号自动映射
0fb017f73c7cbeef559489d3c59ece04b3ac6bb22c8ef19d6e7719b42be100c1
[root@localhost ~]# docker run -itd -P --name web22 --link web11:web11 centos:7 /bin/bash  ##创建并运行容器web22，链接到web11和其通信
5cce142c4def620c595c539561a8267ffb5da4d550accafed83ece38628f7104

测试
进入web22
[root@5cce142c4def /]# ping web11
PING web11 (172.17.0.2) 56(84) bytes of data.
64 bytes from web11 (172.17.0.2): icmp_seq=1 ttl=64 time=0.037 ms
