linux安装docker并实现idea使用证书加密连接 linux安装docker并实现idea使用证

1. 环境准备

阿里云服务器1台
centos7.9
docker最新版

2. docker安装步骤设置仓库

安装所需的软件包。yum-utils 提供了 yum-config-manager ，并且 device mapper 存储驱动程序需要 device-mapper-persistent-data 和 lvm2。

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

设置阿里云源

sudo yum-config-manager \ --add-repo \ http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装最新版本的 Docker Engine-Community 和 containerd

sudo yum install docker-ce docker-ce-cli containerd.io

启动 Docker

sudo systemctl start docker

配置Docker 镜像加速

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io

重启Docker

sudo systemctl daemon-reload sudo systemctl restart docker

3. 配置证书创建一个存放证书目录

mkdir -p /usr/local/ca cd /usr/local/ca

创建一键生成证书脚本

vi ca.sh

按A按键切换为输入模式，然后把下面代码粘贴上去

#!/bin/bash SERVER="服务器外网ip" PASSWORD="yinfeng" COUNTRY="CN" STATE="shanghai" CITY="shanghai" ORGANIZATION="yinfeng" ORGANIZATIONAL_UNIT="dev" EMAIL="yinfeng@qq.com"echo "starting..." cd /usr/local/ca openssl genrsa -aes256 -passout pass:$PASSWORD-out ca-key.pem 4096 openssl req -new -x509 -passin "pass:$PASSWORD" -days 3650 -key ca-key.pem -sha256 -out ca.pem -subj "/C=$COUNTRY/ST=$STATE/L=$CITY/O=$ORGANIZATION/OU=$ORGANIZATIONAL_UNIT/CN=$SERVER/emailAddress=$EMAIL" openssl genrsa -out server-key.pem 4096 openssl req -subj "/CN=$SERVER" -new -key server-key.pem -out server.csr sh -c'echo "subjectAltName = IP:'$SERVER',IP:0.0.0.0" >> extfile.cnf' sh -c'echo "extendedKeyUsage = serverAuth" >> extfile.cn' sh -c'echo "extendedKeyUsage = serverAuth" >> extfile.cnf' openssl x509 -req -days 3650 -in server.csr -CA ca.pem -CAkey ca-key.pem -passin "pass:$PASSWORD" -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 sh -c 'echo extendedKeyUsage=clientAuth >> extfile-client.cnf' openssl x509 -req -days 3650 -sha256 -in client.csr -CA ca.pem -CAkey ca-key.pem -passin "pass:$PASSWORD" -CAcreateserial -out cert.pem -extfile extfile-client.cnf rm client.csr server.csr cp server-*.pem/etc/docker/ cp ca.pem /etc/docker/ echo "========end========"

保存脚本后执行

sh ca.sh

执行完成后会生成以下文件，搜了半天，总结了目前全网唯一可用的脚本，嘿嘿

修改Docker配置

使Docker守护程序仅接收来自提供CA信任的证书的客户端的链接

vim /lib/systemd/system/docker.service

将 ExecStart 属性值进行替换

ExecStart=/usr/bin/dockerd --tlsverify --tlscacert=/usr/local/ca/ca.pem --tlscert=/usr/local/ca/server-cert.pem --tlskey=/usr/local/ca/server-key.pem -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
