#register搭建及使用说明
## 1、搭建参考 搭建指导
## 2、使用：由于这个是个私有镜像仓库，所要在其他机器上使用这个仓库，需要配置/etc/hosts
```Bash
vim /etc/hosts
172.20.2.93 xxxx.sz.test-portus.com
```
## 3、需要配置dockerd的启动项docker.service文件：
```Bash
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd --insecure-registry=xxxx.test-portus.com
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target
```
k8s集群的话需要修改options:
```Bash
/etc/systemd/system/docker.service.d
vim docker-options.conf 添加需要加入的repo
[Service]
Environment="DOCKER_OPTS=--insecure-registry=10.96.0.0/16 --insecure-registry=xxxx.test-portus.com --graph=/var/lib/docker \
--iptables=true"
```
重启docker服务
```Bash
systemctl daemon-reload
systemctl restart docker.service
```
## 4、本地push 镜像，push到xxxx.test-portus.com/public/路径下；
修改一个镜像的tag，使用common-ops账号xxxx密码登陆registry;
```Bash
docker tag busybox:latest xxxx.test-portus.com/public/busybox:test
docker login -ucommon-ops -pxxxx xxxx.test-portus.com
docker push xxxx.test-portus.com/public/busybox:test
删除
docker rmi xxxx.test-portus.com/public/busybox:test
拉去
docker pull xxxx.test-portus.com/public/busybox:test
```
通过window可以访问https://xxxx.test-portus.com 页面上可以查看到刚刚上传的镜像。
