Docker(四) docker本地镜像仓库学习

1. Docker registry

#检查端口5000是否被占用
netstat -tunlp | grep 5000
# the local host ip is 172.17.0.1
# pull registry
mkdir -p /opt/myregistry
docker run -d -p 5000:5000 --name registry --restart=always -v /opt/myregistry:/var/lib/registry registry:2.4.1
# double check the registry is ok.
curl http://172.17.0.1:5000/v2
# modify https to http
echo "{"insecure-registries:["172.17.0.1:5000"]"}"
docker pull busybox
docker tag busybox 172.17.0.1:5000/busybox01
docker rmi busybox
docker push 172.17.0.1:5000/busybox01
docker rmi 172.17.0.1:5000/busybox01
docker pull 172.17.0.1:5000/busybox01

2. Docker hub

• docker hub
  

3. harbor

download harbor offline tar package

wget https://github.com/vmware/harbor/releases/download/v1.2.2/harbor-offline-installer-v1.2.2.tgz -o /home/marion/docker
tar xf /home/marion/docker/harbor-offline-installer-v1.2.2.tgz
cd /home/marion/docker/harbor
安装环境依赖

apt-get install openssl python
安装harbor

配置ssl证书

openssl req -newkey rsa:4096 -nodes -sha256 -keyout ca.key -x509 -days 3650 -out ca.crt
Generating a 4096 bit RSA private key

writing new private key to 'ca.key'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:CN
State or Province Name (full name) [Some-State]:BeiJin
Locality Name (eg, city) []:BeiJin
Organization Name (eg, company) [Internet Widgits Pty Ltd]:haha      
Organizational Unit Name (eg, section) []:haha-ops
Common Name (e.g. server FQDN or YOUR name) []:harbor.haha.link
Email Address []:admin@example.com
root@harbor:~/harbor/harborcert# openssl req -newkey rsa:4096 -nodes -sha256 -keyout haha.link.key -out haha.link.csr

Getting CA Private Key
mkdir -pv /etc/docker/certs.d/harbor.haha.link

更新harbor配置文件

• 　　更新harbor.cfg配置文件
  
  hostname = www.proharbor.com
  ui_url_protocol = https
  ssl_cert = /home/marion/docker/harbor/newcert/proharbor.com.crt
  ssl_cert_key = /home/marion/docker/harbor/newcert/proharbor.com.key
  
• 　　更新docker-compose.yml
  
  # 创建本地仓库镜像的存储目录
  cd /home/marion/docker/harbor
  mkdir /home/marion/harborregistry/
  vim docker-compose.yml

安装harbor以及notary,clair

cd /home/marion/docker/harbor/
sudo ./install.sh --with-notary --with-clair
#关闭harbor所有的容器(必须在含有docker-compose.yml文件的目录下执行)
docker-compose -f ./docker-compose.yml -f ./docker-compose.notary.yml -f ./docker-compose.clair.yml down -v
#启动harbor相关的所有容器(必须在含有docker-compose.yml文件的目录下执行)
docker-compose -f ./docker-compose.yml -f ./docker-compose.notary.yml -f ./docker-compose.clair.yml up -d

验证查看
　　！Harbor

• 打开浏览器，输入https://www.proharbor.com
  
• 用户名/密码：admin/Harbor12345(默认的)
  
• 打开终端: docker login www.proharbor.com ,用户名为admin，密码为Harbor12345
