docker-java的一些简单总结

宿主机:
route add 172.17.0.1 mask 255.255.255.255 192.168.71.1
route print 172.17.0.1

配置密钥方式访问
下面在虚拟机操作：
docker密钥：root
certs文件放置位置：openssl genrsa -aes256 -out ca-key.pem 4096 
openssl req -new -x509 -days 365 -key ca-key.pem -sha256 -out ca.pem
openssl genrsa -out server-key.pem 4096
openssl req -subj "/CN=192.168.71.1" -sha256 -new -key server-key.pem -out server.csr 
echo subjectAltName = DNS:192.168.71.1,IP:192.168.71.1,IP:0.0.0.0,IP:127.0.0.1 >> extfile.cnf
echo extendedKeyUsage = serverAuth >> 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
赋予权限：chmod -v 0400 ca-key.pem key.pem server-key.pem 
chmod -v 0444 ca.pem server-cert.pem cert.pem
到此 文件共有8个  6个*.pem 1 *.cnf  1 srl

vi /lib/systemd/system/docker.service  中添加ExecStart
-D --tlsverify=true --tlscert=/home/nginx/server-cert.pem --tlskey=/home/nginx/server-key.pem --tlscacert=/home/nginx/ca.pem -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

systemctl daemon-reload 
 
service docker restart  //重启docker
 
systemctl status docker //这条命令可以看见你是否设置的生效

到此地址栏失效

下载文件内容：宿主机
1.ca-key.pem     2.ca.pem    3.cert.pem    4.key.pem

宿主机导入密钥库（建议直接拷贝到java sercet文件夹下面）：
keytool -import -alias root  -trustcacerts -file ca.pem -keystore docker.ts  

可以开始连接

简单访问：
vi /lib/systemd/system/docker.service  中添加ExecStart
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --containerd=/run/containerd/containerd.sock

systemctl daemon-reload
systemctl restart docker
