Docker开启远程API
用vim编辑器修改docker.service文件
# 生成证书
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=localhost" -sha256 -new -key server-key.pem -out server.csr
echo subjectAltName = IP:0.0.0.0,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
# 配置Docker
docker --tlsverify --tlscacert=ca.pem --tlscert=server-cert.pem --tlskey=server-key.pem -H=0.0.0.0:2375
# 测试Docker连接
docker --tlsverify --tlscacert=ca.pem --tlscert=cert.pem --tlskey=key.pem -H=tcp://localhost:2375 version
