你必须知道的Docker镜像仓库的搭建

基础知识

Docker

安装 Docker 的注册服务器

1.启动 Docker systemctl start docker

2.下载 Registry 镜像并启动 docker pull registry

[root@luoma target]# docker pull registry
Using default tag: latest
latest: Pulling from library/registry
ddad3d7c1e96: Pull complete 
6eda6749503f: Pull complete 
363ab70c2143: Pull complete 
5b94580856e6: Pull complete 
12008541203a: Pull complete 
Digest: sha256:bac2d7050dc4826516650267fe7dc6627e9e11ad653daca0641437abdf18df27
Status: Downloaded newer image for registry:latest
docker.io/library/registry:latest

3.运行一个 Registry 镜像仓库的容器实例

docker run -d -v /edc/images/registry:/var/lib/registry -p 5000:5000 --restart=always --name xdp-registry registry

运行结果

[root@luoma target]# docker run -d -v /edc/images/registry:/var/lib/registry -p 5000:5000 --restart=always --name xdp-registry registry
f009a2b2baadbfef59f77683203e101e4b135653a437501b7469be2e9a4fbd93

4.开启 Docker 远程 api(针对 CentOS7)

vi /usr/lib/systemd/system/docker.service

原来文件描述符 fd 方式改为 tcp，指定端口 2375

ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

5.让 Docker 支持 http 上传镜像文件（我们本地的 jar 包）

vim /etc/docker/daemon.json

修改为下面内容，其中 registry-mirrors 是阿里云的镜像加速，保持即可。
insecure-registries 中这里的 192.168.114.128 是 Docker 所在服务器的 ip。

{
  "registry-mirrors": ["https://y7tc3g05.mirror.aliyuncs.com"],
  "insecure-registries":["192.168.114.128:5000"] 
}

6.重启 Docker systemctl daemon-reload && systemctl restart docker

7.查看状态 docker ps -a

Docker 测试项目

项目结构

1.Application

package com.jenkins.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
    public static void main(String[] args) throws Exception{
        SpringApplication.run(Application.class,args);
    }
}

2.HelloController

package com.jenkins.demo.Controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class HelloController {
    @RequestMapping("/jenkins")
    @ResponseBody
    public String jenkins() {
        return "Hello Jenkins!";
    }
}

创建运行脚本

1.创建运行脚本

vi /usr/local/jenkins/jenkins.sh

内容如下

app_name='jenkinsdemo'
docker stop ${app_name}
echo '----stop container----'
docker rm ${app_name}
echo '----rm container----'
#-d    后台运行容器，并返回容器 ID，也即启动守护式容器
#-i    以交互模式运行容器，通常与 -t 同时使用
#--name=”容器新名字”    为容器指定一个名称
#-p 指定端口映射，有以下四种格式 hostPort:containerPort
#镜像名称 wlf/${app_name}:1.0-SNAPSHOT
docker run -di --name=${app_name} -p 7070:8080 wlf/${app_name}:1.0-SNAPSHOT
echo '----start container----'

2.给 .sh 脚本添加可执行权限

chmod +x ./jenkins.sh

3.运行

/usr/local/jenkins/jenkins.sh

运行结果

[root@luoma target]# /usr/local/jenkins/jenkins.sh
jenkinsdemo
----stop container----
jenkinsdemo
----rm container----
b9009ed6e206650608532bc6289834371d21ee67ee217a89022691edcce4fdeb
----start container----
