執行命令
./auto-tls-certs.sh 修改docker.service
vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2376
執行
systemctl daemon-reload
systemctl restart docker.service
將3個pem證書放置到客戶端(eg:C:\Users\docker-ca)
下載ca.pem ,cert.pem ,key.pem複製到客戶端C:\Users\docker-ca（路徑自定義）
複製客戶端的證書位置（eg:C:\Users\docker-ca）
如果idea 安裝了docker外掛配置如圖 
如果使用的docker-maven-plugin配置證書位置C:\Users\docker-ca
<plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.2.0</version> <configuration> <serverId>docker-hub</serverId> ...略 <dockerCertPath>C:\Users\docker-ca</dockerCertPath> ...略 </configuration> </plugin>
