## docker 开放远程管理
|
|
|
|
|
|
### 修改docker 服务文件
|
|
|
|
|
|
```shell
|
|
|
|
|
|
vim /usr/lib/systemd/system/docker.service
|
|
|
|
|
|
```
|
|
|
|
|
|
### 启动命令后追加 ```-H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock```
|
|
|
|
|
|
```
|
|
|
|
|
|
#找到ExecStart这行 在后面加上-H tcp://0.0.0.0:2375 其它方式一会docker就挂了 而且重启无效
|
|
|
|
|
|
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
|
|
|
|
|
|
```
|
|
|
|
|
|
### 重启docker
|
|
|
|
|
|
```shell
|
|
|
|
|
|
systemctl daemon-reload
|
|
|
|
|
|
systemctl restart docker
|
|
|
|
|
|
```
|
|
|
|
|
|
### 防火墙开放端口
|
|
|
|
|
|
```
|
|
|
|
|
|
firewall-cmd --zone=public --add-port=2375/tcp --permanent
|
|
|
|
|
|
systemctl reload firewalld
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## portainer 添加远程docker 服务器
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## 配置Docker开启TLS认证
|
|
|
|
|
|
直接开放 Docker 2375 端口容易造成生成事故，被人入侵挖矿之类的， 所以这里开启TLS 认证来安全防护
|
|
|
|
|
|
|
|
|
|
|
|
### 生成TLS证书
|
|
|
|
|
|
创建证书生成脚本 createcert.sh，放置/opt/sh目录
|
|
|
|
|
|
```
|
|
|
|
|
|
mkdir -p /opt/sh /opt/cert/docker
|
|
|
|
|
|
touch /opt/sh/createcert.sh
|
|
|
|
|
|
vim /opt/sh/createcert.sh
|
|
|
|
|
|
```
|
|
|
|
|
|
在createcret.sh添加内容
|
|
|
|
|
|
```
|
|
|
|
|
|
#!/bin/bash
|
|
|
|
|
|
set -e
|
|
|
|
|
|
if [ -z $1 ];then
|
|
|
|
|
|
echo "请输入Docker服务器的域名"
|
|
|
|
|
|
exit 0
|
|
|
|
|
|
fi
|
|
|
|
|
|
HOST=$1
|
|
|
|
|
|
mkdir -p /opt/cert/docker
|
|
|
|
|
|
cd /opt/cert/docker
|
|
|
|
|
|
openssl genrsa -aes256 -out ca-key.pem 4096
|
|
|
|
|
|
openssl req -new -x509 -days 365 -key ca-key.pem -sha256 -out ca.pem
|
|
|
|
|
|
openssl genrsa -out server-key.pem 4096
|
|
|
|
|
|
openssl req -subj "/CN=$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.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
|
|
|
|
|
|
openssl genrsa -out key.pem 4096
|
|
|
|
|
|
openssl req -subj '/CN=client' -new -key key.pem -out client.csr
|
|
|
|
|
|
echo extendedKeyUsage = clientAuth > extfile.cnf
|
|
|
|
|
|
openssl x509 -req -days 365 -sha256 -in client.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out cert.pem -extfile extfile.cnf
|
|
|
|
|
|
rm -v client.csr server.csr
|
|
|
|
|
|
chmod -v 0400 ca-key.pem key.pem server-key.pem
|
|
|
|
|
|
chmod -v 0444 ca.pem server-cert.pem cert.pem
|
|
|
|
|
|
```
|
|
|
|
|
|
执行 createcert.sh 脚本，生成证书放置 /opt/cert/docker 目录中
|
|
|
|
|
|
```
|
|
|
|
|
|
# wuanwanghao.top 是服务器的域名
|
|
|
|
|
|
sh /opt/sh/createcert.sh wuanwanghao.top
|
|
|
|
|
|
```
|
|
|
|
|
|
按照提示输入相关信息，密码一致，其他信息可留空，等脚本指定完成之后，可在 /opt/cert/docker 目录查看到生成的证书。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 配置Docker开启TLS认证
|
|
|
|
|
|
```
|
|
|
|
|
|
vim /usr/lib/systemd/system/docker.service
|
|
|
|
|
|
```
|
|
|
|
|
|
在ExecStart属性后追加
|
|
|
|
|
|
```
|
|
|
|
|
|
--tlsverify --tlscacert=/opt/cert/docker/ca.pem \
|
|
|
|
|
|
--tlscert=/opt/cert/docker/server-cert.pem \
|
|
|
|
|
|
--tlskey=/opt/cert/docker/server-key.pem \
|
|
|
|
|
|
-H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
|
|
|
|
|
|
```
|
|
|
|
|
|
### 重新加载docker配置后重启
|
|
|
|
|
|
```
|
|
|
|
|
|
systemctl daemon-reload
|
|
|
|
|
|
systemctl restart docker
|
|
|
|
|
|
```
|
|
|
|
|
|
查看2376端口是否启动
|
|
|
|
|
|
```
|
|
|
|
|
|
netstat -nltp | grep 2375
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
本地连接测试Docker API是否可用
|
|
|
|
|
|
|
|
|
|
|
|
没有指定证书访问测试
|
|
|
|
|
|
```
|
|
|
|
|
|
curl https://wuanwanghao.top:2375/info
|
|
|
|
|
|
```
|
|
|
|
|
|
指定证书访问测试
|
|
|
|
|
|
```
|
|
|
|
|
|
curl https://wuanwanghao.top:2375/info --cert /opt/cert/docker/cert.pem --key /opt/cert/docker/key.pem --cacert /opt/cert/docker/ca.pem
|
|
|
|
|
