1.环境准备
# 查看Docker服务器主机名hostnamectl
这里记住我的主机名s130就好
# 静态主机名修改vi /etc/hostname# 临时主机名修改（重启失效）hostname s130 2.创建TLS证书
创建create_crets.sh文件并执行，生成的证书在/certs/docker目录下，
# create_crets.sh,将【证书生成脚本】内容复制进去touch create_crets.sh chmod 755 create_crets.sh# 证书生成脚本#!/bin/bashset -eif [ -z $1 ];then echo "请输入Docker服务器主机名" exit 0fiHOST=$1mkdir -p /certs/dockercd /certs/dockeropenssl genrsa -aes256 -out ca-key.pem 4096openssl req -new -x509 -days 365 -key ca-key.pem -sha256 -out ca.pemopenssl genrsa -out server-key.pem 4096openssl req -subj "/CN=$HOST" -sha256 -new -key server-key.pem -out server.csr# 配置白名单，推荐配置0.0.0.0，允许所有IP连接但只有证书才可以连接成功echo subjectAltName = DNS:$HOST,IP:0.0.0.0 > extfile.cnfopenssl x509 -req -days 365 -sha256 -in server.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out server-cert.pem -extfile extfile.cnfopenssl genrsa -out key.pem 4096openssl req -subj ‘/CN=client‘ -new -key key.pem -out client.csrecho extendedKeyUsage = clientAuth > extfile.cnfopenssl x509 -req -days 365 -sha256 -in client.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out cert.pem -extfile extfile.cnfrm -v client.csr server.csrchmod -v 0400 ca-key.pem key.pem server-key.pemchmod -v 0444 ca.pem server-cert.pem cert.pem执行脚本生成证书，按照提示输入
# 传递的参数s130为服务器的主机名，不能是IPsh create_crets.sh s130
所有密码输入同一个就好，要注意输入Docker服务器主机名s130
3.配置Docker开启TLS认证
vi /usr/lib/systemd/system/docker.service# 在ExecStart属性后追加--tlsverify --tlscacert=/certs/docker/ca.pem --tlscert=/certs/docker/server-cert.pem --tlskey=/certs/docker/server-key.pem \-H tcp://0.0.0.0:2376 -H unix://var/run/docker.sock \
# 重新加载docker配置后重启systemctl daemon-reloadsystemctl restart docker# 查看2376端口是否启动netstat -tunlp
4.Docker Remote API本机连接测试
# 没有指定证书时，报错含义是签发证书机构未经认证，无法识别curl https://s130:2376/info 
# 指定证书访问okcurl https://s130:2376/info --cert /certs/docker/cert.pem --key /certs/docker/key.pem --cacert /certs/docker/ca.pem
5.IDEA连接配置和测试
从Docker服务器生成的客户端所需的3个密钥下载到我们本地机器上去
配置本地机器的域名解析映射(推荐SwitchHosts工具)
打开IDEA配置Docker Remote API的URL和密钥存放的路径
maven配置修改
