docker、ubuntu、linux、远程连接、IntelliJ idea
注意！本文中开启docker远程连接的方法只能在确定环境安全的内网中使用，不可在公网服务器设置，有极大安全风险！

步骤
> vim /usr/lib/systemd/system/docker.service # set nu 打开行号
- 找到第13行ExecStart，在末尾添加
-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375，如下：

- 重启
systemctl daemon-reload
systemctl restart docker
重启后不要忘记把开发环境使用的MySQL和Redis容器启动起来
- 检查2375端口是否开放
> ss -tuln
使用curl连接一下
> curl http://localhost:2375/version

- 生成安全证书
执行下面这个脚本：
#!/bin/bash#相关配置信息
SERVER="192.168.56.10"
PASSWORD="vagrant"
COUNTRY="CN"
STATE="Shan Dong"
CITY="Ji Nan"
ORGANIZATION="Huai Yin"
ORGANIZATIONAL_UNIT="Dev"
EMAIL="xkm.0jiejie0@qq.com"###开始生成文件###
echo "开始生成文件"#切换到生产密钥的目录
if [ ! -d "/opt/docker_ca" ]; then
mkdir -p /opt/docker_ca
fi
cd /opt/docker_ca
#生成ca私钥(使用aes256加密)
openssl genrsa -aes256 -passout pass:$PASSWORD -out ca-key.pem 4096
#生成ca证书，填写配置信息
openssl req -new -x509 -passin "pass:$PASSWORD" -days 365 -key ca-key.pem -sha256 -out ca.pem -subj "/C=$COUNTRY/ST=$STATE/L=$CITY/O=$ORGANIZATION/OU=$ORGANIZATIONAL_UNIT/CN=$SERVER/emailAddress=$EMAIL"#生成server证书私钥文件
openssl genrsa -out server-key.pem 4096
#生成server证书请求文件
openssl req -subj "/CN=$SERVER" -sha256 -new -key server-key.pem -out server.csr
#配置白名单，多个用逗号隔开
sh -c 'echo subjectAltName = IP:'$SERVER',IP:0.0.0.0 >> extfile.cnf'
#把 extendedKeyUsage = serverAuth 键值设置到extfile.cnf文件里，限制扩展只能用在服务器认证
sh -c 'echo extendedKeyUsage = serverAuth >> extfile.cnf'
#使用CA证书及CA密钥以及上面的server证书请求文件进行签发，生成server自签证书
openssl x509 -req -days 365 -sha256 -in server.csr -CA ca.pem -CAkey ca-key.pem -passin "pass:$PASSWORD" -\CAcreateserial -out server-cert.pem -extfile extfile.cnf#生成client证书RSA私钥文件
openssl genrsa -out key.pem 4096
#生成client证书请求文件
openssl req -subj '/CN=client' -new -key key.pem -out client.csr
#继续设置证书扩展属性
sh -c 'echo extendedKeyUsage = clientAuth >> extfile.cnf'
#生成client自签证书（根据上面的client私钥文件、client证书请求文件生成）
openssl x509 -req -days 365 -sha256 -in client.csr -CA ca.pem -CAkey ca-key.pem -passin "pass:$PASSWORD" -\CAcreateserial -out cert.pem -extfile extfile.cnf#更改密钥权限
chmod 0400 ca-key.pem key.pem server-key.pem
#更改密钥权限
chmod 0444 ca.pem server-cert.pem cert.pem
#删除无用文件
rm client.csr server.csrecho "生成文件完成"
###生成结束###
- 修改Docker配置
# 打开docker配置文件 (这个和上面的是一个文件，其使用了软链接，路径不同而已，不用纠结)
> vim /lib/systemd/system/docker.service
# 在ExecStart的/usr/bin/dockerd后面加\，然后添加如下的配置信息
ExecStart=/usr/bin/dockerd \--tlsverify \--tlscacert=/opt/docker_ca/ca.pem \--tlscert=/opt/docker_ca/server-cert.pem \--tlskey=/opt/docker_ca/server-key.pem \-H tcp://0.0.0.0:2376 \-H unix:///var/run/docker.sock \-H fd:// --containerd=/run/containerd/containerd.sock
# 重新启动docker
> systemctl daemon-reload && systemctl restart docker
ctrl+alt+s打开设置
Tools > SSH Configurations，点击+，输入IP、用户名、密码，点击apply
- 配置idea客户端
将/opt/docker-ca目录下的ca.pem,cert.pem,key.pem（我这复制了所有.pem文件，懒得挑了）复制到自己的电脑中某固定目录（和虚拟机放在一起，建个文件夹：dockerFile）
在idea设置中，找到 Build,Execution,Deployment > Docker，点击+，连接方式选择TCP socket
url: https://192.168.56.10:2376
证书路径：D:\dev\iso\dockerFile\dockerFile
可以看到下方提示 Connection successful
- 点击确定，可以看到下方service窗口中出现了docker服务，双击连接，可以看到容器、镜像、网络、卷（英文）
点击具体容器实例的看板，可以看到其版本配置信息；
点击镜像，可以在右侧框中输入镜像名称拉取镜像（不知道为什么没有搜索功能，可能是我没找到）；
这样一来用起docker要方便得多。
