搭建Docker私有仓库

　　前言：不断学习就是程序员的宿命

1、环境准备

　　服务器：centos7、内核5.6

　　

　内核升级：

yum update -y

# 导入公钥
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org 

# 安装7.x版本的ELRepo
rpm -Uvh https://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm

# 安装新版本内核
yum --enablerepo=elrepo-kernel install kernel-lt -y

Centos7.x 内核升级完毕后，需要修改内核的启动顺序
vim /etc/default/grub

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved        #把这里的saved改成0
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet net.ifnames=0"
GRUB_DISABLE_RECOVERY="true"

  运行grub2-mkconfig命令来重新创建内核配置，命令是grub2-mkconfig -o /boot/grub2/grub.cfg，如下:

grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...

done

2、服务端搭建

　　根据GitHub中issue：https://github.com/docker/distribution-library-image/issues/106，鄙人一直用最新的镜像，后续配置有问题，所以改用2.6.x

# 下载 registry
docker pull registry:2.6.2
# 挂载相关的配置
mkdir -p  /docker/registry/auth
# 生成账号密码：msi msi123
docker run --entrypoint htpasswd registry:latest -Bbn msi msi123  >> /docker/registry/auth/htpasswd
# 设置配置文件
mkdir -p  /docker/registry/config
vim  /docker/registry/config/config.yml
# 输入以下文件

version: 0.1
log:
  fields:
    service: registry
storage:
  delete:
    enabled: true
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry
http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
threshold: 3
启动
docker run -d -p 5005:5000 --restart=always  --name=registry \
-v /docker/registry/config/:/etc/docker/registry/ \
-v /docker/registry/auth/:/auth/ \
-e "REGISTRY_AUTH=htpasswd" \
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
-e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \
-v /docker/registry/:/var/lib/registry/ \
registry:2.6.2

3、配置客户端

vim /etc/hosts
192.168.56.10 msi-registry

######登录
docker login 192.168.56.10:5005

# Error response from daemon: Get https://192.168.56.10:5005/v1/users/: dial tcp 192.168.56.10:5005: i/o timeout
# 解决：https://blog.csdn.net/quanqxj/article/details/79479943
# Error response from daemon: Get https://192.168.56.10:5005/v2/: http: server gave HTTP response to HTTPS client
# 解决：
# vim /etc/docker/daemon.json
# 添加如下内容
# {"insecure-registries":["msi-registry:5005","msi-registry"]}
