在Ubuntu16.10上开启docker17.03.0-ce的https认证
在Ubuntu16.10上开启docker17.03.0-ce的https认证
1、生成CA私钥和公钥：
$ openssl genrsa -aes256 -out ca-key.pem 4096
效果如下：
Generating RSA private key,4096bit long modulus............................................................................................................................................................................................++........++e is65537(0x10001)
Enter pass phraseforca-key.pem: cloud
Verifying - Enter pass phraseforca-key.pem: cloud
需要记住设置的key，下面要用
2、进行证书生成
$ openssl req -new -x509 -days 365 -key ca-key.pem -sha256 -out ca.pem
Enter pass phrase for ca-key.pem:
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:shandong
Locality Name (eg, city) []:jinan
Organization Name (eg, company) Internet Widgits Pty Ltd:zhangyc
Organizational Unit Name (eg, section) []:zhangyc
Common Name (e.g. server FQDN or YOUR name) []:zhangyc
Email Address []:lz2392504@gmail.com
3、根据根证书，生成服务器证书、客户端证书
$ openssl genrsa -out server-key.pem 4096
$ openssl req -subj "/CN=cloudtop" -sha256 -new -key server-key.pem -out server.csr
$ echo subjectAltName = DNS:cloudtop,IP:172.31.142.210,IP:127.0.0.1 > extfile.cnf
$ openssl x509 -req -days 365 -sha256 -in server.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out server-cert.pem -extfile extfile.cnf
$ openssl genrsa -out key.pem 4096
$ openssl req -subj '/CN=client' -new -key key.pem -out client.csr
$ echo extendedKeyUsage = clientAuth > extfile.cnf
$ openssl x509 -req -days 365 -sha256 -in client.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out cert.pem -extfile extfile.cnf
$ rm -v client.csr server.csr
$ chmod -v 0400 ca-key.pem key.pem server-key.pem
$ chmod -v 0444 ca.pem server-cert.pem cert.pem
$ sudo vim /etc/systemd/system/docker.service.d/http-proxy.conf
新版需要编辑/etc/systemd/system/docker.service.d/docker.conf
$ sudo cat /etc/systemd/system/docker.service.d/docker.conf
Service
ExecStart=
ExecStart=/usr/bin/dockerd --tlsverify --tlscacert=/home/zhangyc/ca.pem --tlscert=/home/zhangyc/server-cert.pem --tlskey=/home/zhangyc/server-key.pem -H=172.31.142.111:4096
4、启动配置参考
