docker创建私有仓库

docker pull registry
罗列nat表
iptables -t nat -L
docker-compose

docker run -d -p 5001:5000 registry 启动docker私有仓库
默认情况下，会将仓库存放于容器内的/tmp/registry目录下，这样如果容器被删除，则存放于容器中的镜像也会丢失，所以我们一般情况下会指定本地一个目录挂载到容器内的/tmp/registry下，如下：

[root@localhost opt]# docker run -d -p 5000:5000 -v /opt/registry:/tmp/registry docker.io/registry
操作如下：
[root@docker-test ~]#
docker run -d registry
92d53997aad62c5ad8c8b1aa6b29373026ae80db97295628e6100e9f168d6b5d
[root@docker-test ~]# docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
92d53997aad6 registry "/entrypoint.sh /etc/" 57 seconds ago Up 53 seconds 5000/tcp zen_nobel

传东西到仓库里

打包镜像到私有仓库里：
docker tag java 10.20.23.144:5000/test/java:v1

结果如下：
[root@docker-test ~]# docker images
10.20.23.144:5000/test/java v1 d23bdf5b1b1b 11 weeks ago 643.1 MB

从私有仓库里下载：
docker push 10.20.23.144:5000/test/java:v1
下载失败
要在docker配置文件里加上一段
vim /etc/sysconfig/docker
DOCKER_OPTS="--registry-mirror=http://aad0405c.m.daocloud.io"
ADD_REGISTRY='--add-registry 10.20.23.144:5000'
INSECURE_REGISTRY='--insecure-registry 10.20.23.144:5000'
systemctl restart docker
再次操作;
docker run -d -p 5000:5000 -v /opt/registry:/tmp/registry docker.io/registry
docker tag docker.io/elasticsearch:latest 10.20.23.144:5000/test/es
下载docker镜像：
docker push 10.20.23.144:5000/test/es:latest

在另一台机子上要用
docker pull 下载下来

docker pull 10.20.23.144:5000/test/es
