本地主机通过portainer面板管理远程主机docker:
mkdir server-ca && cd server-ca
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=8.8.8.8" -sha256 -new -key server-key.pem -out server.csr
echo subjectAltName = DNS:8.8.8.8,IP:10.10.10.20,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
远程主机证书生成好了,接下来生成本地主机证书(为了方便可以在远程主机新建client-ca,该目录下):
需要用到ca中生成的两个文件,cp过来
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
停掉docker
sudo systemctl stop docker
server-ca目录执行
sudo dockerd --tlsverify --tlscacert=ca.pem --tlscert=server-cert.pem --tlskey=server-key.pem -H=0.0.0.0:2376 -H unix:///var/run/docker.sock &
等重启完毕
