docker私服仓库搭建

发表于 | 分类于

docker官方提供私服镜像，我们可以很方便的启动一个docker私服仓库

1
2
mkdir -p /data/program/docker-registry
docker run -d -p 5000:5000 -v /data/program/docker-registry:/var/lib/registry --name docker-registry --restart=always registry

注意：这样启动的私服只能通过http访问，客户端使用需要做一定的配置

Ubuntu

nano /etc/docker/daemon.json
添加"insecure-registries"
{
"insecure-registries": ["x.x.x.x:5000"]
}

这样的私服镜像是公开可访问的，我们可以在docker-registry前加上nginx做https的代理转发同时配置用户登录

注：替换xx.com为你自己申请的域名

acme.sh域名证书配置

apt install socat

curl  https://get.acme.sh | sh

cd ~/.acme.sh/

申请签发 SSL 证书
sh acme.sh --issue -d xx.com --standalone

# 证书安装目录
mkdir -p /opt/certs

cd ~/.acme.sh/

安装证书

sh acme.sh --installcert -d xx.com --keypath /opt/certs/xx.com.key --fullchainpath /opt/certs/xx.com.pem --reloadcmd     "/data/release/nginx-1.15.0/sbin/nginx -s reload"

# /opt/certs/ 是证书安装目录
# /data/release/nginx-1.15.0/sbin/nginx为nginx安装路径
# reloadcmd 是nginx 的reload 命令  acme.sh 记住重启 Nginx 的命令，以后自动更新证书的动作需要重启 Nginx，然后你会看到结果

生成 dhparam.pem 文件
openssl dhparam -out /opt/certs/dhparam.pem 2048

配置docker 私服 与nginx

mkdir -p /data/program/docker-registry

cd /data/program/docker-registry

# 安装apache 工具箱
apt install apache2-utils
# 生成私服访问账号密码
htpasswd -bc nginx.htpasswd admin 123456

nginx 配置:/data/release/nginx-1.15.0/conf/conf.d/docker-registry.conf
测试访问：https://xx.com:10090/v2/
返回{}

docker-registry.conf
