环境：IntelliJ IDEA 2018.1.6 x64、CentOS 7
一、无CA认证方式
注意：无ca认证不安全，推荐仅自己可见的时候使用
1、修改服务器配置，开放Docker的远程连接访问
[root@localhost ~]# vim /usr/lib/systemd/system/docker.service
- 将ExecStart属性value值改为
/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
2、重启docker
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker
3、开放防火墙2375端口
firewall-cmd --add-port=2375/tcp
4、随便写个接口，等会进行测试
5、idea安装docker integration插件
- 插件安装完成重启idea后可以看到底部多了个docker标志
5、接下来给项目打成jar包
6、然后编写DockerFile
- 我这里找了个相对比较小的jdk，是在官方镜像库找到的
- 也可以在国内的镜像库里找，如：FROM hub.c.163.com/library/java:8-jre
FROM 99taxis/mini-java8
ADD target/*.jar idea-docker-deploy.jar
EXPOSE 8765
ENTRYPOINT ["java", "-jar", "idea-docker-deploy.jar"]
项目右键新建一个没有后缀的File
7、接下来配置idea一键部署
- 选中第一个
- 如图进行填写
8、运行容器
- 可以看到相应的日志
9、访问接口
成功
- 也可以在服务器上打命令查看
[root@localhost ~]# docker images

二、有CA认证方式
注意：前面提到的配置是允许所有人都可以访问的，因为docker默认是root权限的，你把2375端口暴露在外面，意味着别人随时都可以提取到你服务器的root权限，是很容易被黑客黑的，因此,docker官方推荐使用加密的tcp连接，以Https的方式与客户端建立连接
1、创建ca文件夹，存放CA私钥和公钥
[root@localhost ~]# mkdir -p /usr/local/ca
[root@localhost ~]# cd /usr/local/ca/
2、创建密码
- 需要连续输入两次相同的密码
[root@localhost ca]# openssl genrsa -aes256 -out ca-key.pem 4096
Generating RSA private key, 4096 bit long modulus
...................++
..........................................................................................................................................................................................................................................................................................................................................................++
e is 65537 (0x10001)
Enter pass phrase for ca-key.pem:
Verifying - Enter pass phrase for ca-key.pem:
3、依次输入密码、国家、省、市、组织名称等
[root@localhost ca]# openssl req -new -x509 -days 365 -key ca-key.pem -sha256 -out ca.pem
Enter pass phrase for ca-key.pem:
Enter pass phrase for ca-key.pem:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:zj
Locality Name (eg, city) [Default City]:hz
Organization Name (eg, company) [Default Company Ltd]:qdsg
Organizational Unit Name (eg, section) []:qdsg
Common Name (eg, your name or your server's hostname) []:qdsg
Email Address []:1@qq.com
[root@localhost ca]# openssl genrsa -out server-key.pem 4096
Generating RSA private key, 4096 bit long modulus
...........................++
................++
e is 65537 (0x10001)
4、生成server-key.pem
[root@localhost ca]# openssl genrsa -out server-key.pem 4096
Generating RSA private key, 4096 bit long modulus
.................................................................................................................................................++
.................................................++
e is 65537 (0x10001)
5、把下面的$Host换成你自己服务器外网的IP或者域名
openssl req -subj "/CN=$HOST" -sha256 -new -key server-key.pem -out server.csr
比如
openssl req -subj "/CN=192.168.1.106" -sha256 -new -key server-key.pem -out server.csr
或
openssl req -subj "/CN=www.baidu.com" -sha256 -new -key server-key.pem -out server.csr
6、配置白名单
也就是你接下来要允许那些ip可以连接到服务器的docker，因为已经是ssl连接，所以我推荐配置0.0.0.0,也就是所有ip都可以连接(但只有拥有证书的才可以连接成功)，这样配置好之后公司其他人也可以使用。如果你不想这样，那你可以配置ip，用逗号分隔开。下面的$Host依旧是你服务器外网的IP或者域名，请自行替换。
注意！！！！这里我踩了坑
- 如果你填写的是ip地址的话命令如下
echo subjectAltName = IP:$HOST,IP:0.0.0.0 >> extfile.cnf
- 如果你填写的是域名的话命令如下
echo subjectAltName = DNS:$HOST,IP:0.0.0.0 >> extfile.cnf
7、执行命令，将Docker守护程序密钥的扩展使用属性设置为仅用于服务器身份验证
[root@localhost ca]# echo extendedKeyUsage = serverAuth >> extfile.cnf
8、执行命令，并输入之前设置的密码，生成签名证书
[root@localhost ca]# openssl x509 -req -days 365 -sha256 -in server.csr -CA ca.pem -CAkey ca-key.pem \-CAcreateserial -out server-cert.pem -extfile extfile.cnf
Signature ok
subject=/CN=192.168.1.106
Getting CA Private Key
Enter pass phrase for ca-key.pem:
9、生成客户端的key.pem，到时候把生成好的几个公钥私钥拷出去即可
[root@localhost ca]# openssl genrsa -out key.pem 4096
Generating RSA private key, 4096 bit long modulus
...........................................................................................................................................................................................................................................................................................................................................................................++
......................................................................................................................................++
e is 65537 (0x10001)
10、执行命令
[root@localhost ca]# openssl req -subj '/CN=client' -new -key key.pem -out client.csr
11、执行命令，要使密钥适合客户端身份验证，请创建扩展配置文件
[root@localhost ca]# echo extendedKeyUsage = clientAuth >> extfile.cnf
12、生成cert.pem,需要输入前面设置的密码，生成签名证书
[root@localhost ca]# openssl x509 -req -days 365 -sha256 -in client.csr -CA ca.pem -CAkey ca-key.pem \-CAcreateserial -out cert.pem -extfile extfile.cnf
Signature ok
subject=/CN=client
Getting CA Private Key
Enter pass phrase for ca-key.pem:
13、删除不需要的文件，两个证书签名请求
[root@localhost ca]# rm -v client.csr server.csr
rm：是否删除普通文件 "client.csr"？y
已删除"client.csr"
14、修改权限，要保护您的密钥免受意外损坏，请删除其写入权限。要使它们只能被您读取，更改文件模式
[root@localhost ca]# chmod -v 0400 ca-key.pem key.pem server-key.pem
mode of "ca-key.pem" changed from 0644 (rw-r--r--) to 0400 (r--------)
mode of "key.pem" changed from 0644 (rw-r--r--) to 0400 (r--------)
mode of "server-key.pem" changed from 0644 (rw-r--r--) to 0400 (r--------)
- 证书可以是对外可读的，删除写入权限以防止意外损坏
[root@localhost ca]# chmod -v 0444 ca.pem server-cert.pem cert.pem
mode of "ca.pem" changed from 0644 (rw-r--r--) to 0444 (r--r--r--)
mode of "server-cert.pem" changed from 0644 (rw-r--r--) to 0444 (r--r--r--)
mode of "cert.pem" changed from 0644 (rw-r--r--) to 0444 (r--r--r--)
15、归集服务器证书
[root@localhost ca]# cp server-*.pem /etc/docker/
[root@localhost ca]# cp ca.pem /etc/docker/
16、修改Docker配置，使Docker守护程序仅接受来自提供CA信任的证书的客户端的连接
[root@localhost ca]# vim /lib/systemd/system/docker.service
- 将 ExecStart=/usr/bin/dockerd 替换为：
ExecStart=/usr/bin/dockerd --tlsverify --tlscacert=/etc/docker/ca.pem --tlscert=/etc/docker/server-cert.pem --tlskey=/etc/docker/server-key.pem -H tcp://0.0.0.0:2376 -H unix:///var/run/docker.sock
17、重新加载daemon并重启docker
[root@localhost ~]# sudo systemctl daemon-reload && sudo systemctl restart docker
18、开放防火墙2375端口
firewall-cmd --add-port=2375/tcp
19、保存相关客户端的pem文件到本地
20、idea的配置
21、若出现以下错误，请查看前面的步骤是否遗漏或出错
