【微服务架构 - 06 - 部署】01 真正实现：一次构建，到处运行

GitLab

• 新建 myshop 项目

• 使用 ssh 克隆到本地

• 将代码复制进 myshop

• 提交到本地仓库

• 提交到远程仓库

从 GitLab 拉取源代码到 Docker 容器中

• 生成 SSH KEY

ssh-keygen -t rsa -C "[email protected]"

执行成功后的效果：

root@ubuntu:/usr/local# ssh-keygen -t rsa -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:SNSUCY8K6uGvALnQjKzbVuGSjLxssXC01uFdjQ2CvTQ [email protected]
The key's randomart image is:
+---[RSA 2048]----+
|     oo+.o       |
|    ..Eo=        |
|  .  .o+.=       |
|.*..oo..o o      |
|B*o*.+..S        |
|O+O = .          |
|*=+o             |
|.Bo              |
|ooo.             |
+----[SHA256]-----+

• 进入 /root/.ssh/ 目录，获取密钥

root@ubuntu:/usr/local# cd /root/.ssh/
root@ubuntu:~/.ssh# vi id_rsa.pub

• 配置到 GitLab SSH 密钥中

• 克隆到容器中

root@ubuntu:/usr/local/docker# clear
root@ubuntu:/usr/local/docker# git clone ssh://[email protected]:2222/Yuu/myshop.git

Maven 打包

root@ubuntu:/usr/local/docker/myshop# mvn clean package -Dmaven.test.skip=true

打包镜像

• 将项目的 tar.gz 包，移入 /docker/myshop/image 目录中

• 创建 Dockerfile 文件

FROM tomcat

WORKDIR /usr/local/tomcat/webapps/ROOT

RUN rm -fr *

ADD myshop.tar.gz /usr/local/tomcat/webapps/ROOT

RUN rm -fr myshop.tar.gz

WORKDIR /usr/local/tomcat

• 构建镜像

docker build -t 192.168.106.128:5000/myshop .

• 推送镜像到私服

docker push 192.168.106.128:5000/myshop

创建一个 MyShop 容器

• 编写 docker-compose.yml 文件

version: '3.1'
services:
  myshop:
    restart: always
    image: 192.168.106.128:5000/myshop
    container_name: myshop
    ports:
      - 8080:8080

• 配置私服客户端

root@ubuntu:/usr/local/docker# cd /etc/docker/
root@ubuntu:/etc/docker# vi daemon.json

{
  "registry-mirrors": [
    "https://registry.docker-cn.com"
  ],
  "insecure-registries": [
    "ip:5000"
  ]
}

• 重启 Docker

$ systemctl restart docker

• 启动 myshop 容器

$ docker-compose up -d

访问 MyShop
