Docker Access to the remote API

Step1：编写自动CA证书生成脚本

#!/bin/bash
ip=10.6.119.21
password=zhangyou@1988
dir=/root/docker/cert

if [ ! -d "$dir" ];then
echo ""
echo "$dir , not dir , will create"
echo ""
mkdir -p $dir
else
echo ""
echo "$dir , dir exist , will delete and create"
echo ""
rm -rf $dir
mkdir -p $dir
fi
 
cd $dir
# 创建根证书RSA私钥
openssl genrsa -aes256 -passout pass:$password  -out ca-key.pem 4096
# 创建CA证书
openssl req -new -x509 -days 3650 -key ca-key.pem -passin pass:$password -sha256 -out ca.pem -subj "/C=CN/ST=shanghai/L=jiading/O=UnitedImaging/CN=$ip"

# 创建服务端私钥
openssl genrsa -out server-key.pem 4096
# 创建服务端签名请求证书文件
openssl req -subj "/CN=$ip" -sha256 -new -key server-key.pem -out server.csr
echo subjectAltName = IP:$ip,IP:0.0.0.0 >> extfile.cnf
echo extendedKeyUsage = serverAuth >> extfile.cnf
# 创建签名生效的服务端证书文件 
openssl x509 -req -days 3650 -sha256 -in server.csr -CA ca.pem -CAkey ca-key.pem -passin "pass:$password" -CAcreateserial -out server-cert.pem -extfile extfile.cnf

# 创建客户端私钥
openssl genrsa -out key.pem 4096
# 创建客户端签名请求证书文件
openssl req -subj '/CN=client' -new -key key.pem -out client.csr
echo extendedKeyUsage = clientAuth >> extfile.cnf 
echo extendedKeyUsage = clientAuth > extfile-client.cnf
# 创建签名生效的客户端证书文件
openssl x509 -req -days 3650 -sha256 -in client.csr -CA ca.pem -CAkey ca-key.pem -passin "pass:$password" -CAcreateserial -out cert.pem -extfile extfile-client.cnf

# 删除多余文件
rm -f -v client.csr server.csr extfile.cnf extfile-client.cnf 
chmod -v 0400 ca-key.pem key.pem server-key.pem
chmod -v 0444 ca.pem server-cert.pem cert.pem

Step2：添加执行权限&执行脚本生成证书

​​

Step3：配置docker.service

​​

Step4：重启docker.service

#刷新配置
systemctl daemon-reload
#重启docker
systemctl restart docker.service

Step5：测试
