部署Docker Registry v2服务

2017-01-06

生成自签名证书 #

因为没有公网ip和域名，所以这里修改/etc/pki/tls/openssl.cnf以生成带SAN 扩展的证书。在openssl.cnf文件中修改以下内容:

1[ v3_ca ]
2#指定ip
3subjectAltName=IP:192.168.61.100

创建证书目录:

1mkdir -p /home/registry/certs
2mkdir -p /home/registry/data

生成自签名证书：

1cd /home/registry/certs
2
3openssl req \
4     -newkey rsa:2048 -nodes -keyout domain.key \
5     -x509 -days 3650 -out domain.crt

根据提示引导，输入信息创建证书:

 1You are about to be asked to enter information that will be incorporated
 2into your certificate request.
 3What you are about to enter is what is called a Distinguished Name or a DN.
 4There are quite a few fields but you can leave some blank
 5For some fields there will be a default value,
 6If you enter '.', the field will be left blank.
 7-----
 8Country Name (2 letter code) [XX]:CN
 9State or Province Name (full name) []:Beijing
10Locality Name (eg, city) [Default City]:Beijing
11Organization Name (eg, company) [Default Company Ltd]:
12Organizational Unit Name (eg, section) []:
13Common Name (eg, your name or your server's hostname) []:192.168.61.100

查看创建的证书和私钥:

1ls
2domain.crt  domain.key
3
4openssl x509 -text -noout -in domain.crt

运行registry容器 #

1docker run -d -p 5000:5000 --restart=always --name registry \
2  -v /home/registry/certs:/certs \
3  -v /home/registry/data:/var/lib/registry \
4  -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
5  -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
6  registry:2

将domain.cert拷贝到每个docker所在主机的/etc/docker/certs.d/192.168.61.100:5000/ca.crt

1mkdir -p /etc/docker/certs.d/192.168.61.100:5000
2cp domain.crt /etc/docker/certs.d/192.168.61.100:5000/ca.crt

重启docker：

1systemctl restart docker

测试pull和push:

1docker pull alpine
2docker tag alpine 192.168.61.100:5000/alpine
3
4docker push 192.168.61.100:5000/alpine
5
6docker rmi 192.168.61.100:5000/alpine
7docker rmi alpine
8
9docker pull 192.168.61.100:5000/alpine

开启basic认证 #

 1mkdir -p /home/registry/auth
 2cd /home/registry/auth
 3
 4docker run --entrypoint htpasswd registry:2 -Bbn testuser testpassword > htpasswd
 5
 6docker stop registry
 7docker rm registry
 8
 9docker run -d -p 5000:5000 --restart=always --name registry \
10  -v /home/registry/auth:/auth \
11  -e "REGISTRY_AUTH=htpasswd" \
12  -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
13  -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \
14  -v /home/registry/certs:/certs \
15  -v /home/registry/data:/var/lib/registry \
16  -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
17  -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
18  registry:2

验证login,push

1docker login 192.168.61.100:5000
2Username: testuser
3Password:
4Login Succeeded
5
6docker push 192.168.61.100:5000/alpine
