docker高效搭建本地开发环境_本地搭建docker

背景

Docker 是一个用于开发、发布和运行应用程序的开放平台。Docker 使您能够将应用程序与基础架构分离，以便您可以快速交付软件。使用 Docker，您可以像管理应用程序一样管理基础设施。通过利用 Docker 快速交付、测试和部署代码的方法，可以显着减少编写代码和在生产环境中运行之间的延迟。

安装docker

安装参考官方地址进行安装即可。以centos7为例，使用yum安装。

更新yum源

sudo yum update
1

安装Docker所需要的一些工具包

sudo yum install -y yum-utils
1

建立Docker仓库 (映射仓库地址)

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

安装docker引擎

 sudo yum install docker-ce docker-ce-cli containerd.io
1

启动docker

sudo systemctl start docker
1

以安装redis为例

启动docker

#启动docker
sudo systemctl start docker
1
2

查看镜像

#查看镜像
docker images
1
2

查看redis版本

#查看软件的版本
$ docker search  redis
1
2

获取最新的版本redis

#获取最新的版本
docker pull redis:latest
1
2

查看是否下载成功

docker images
1

启动redis

#启动redis
docker run -itd --name redis -p 6379:6379 redis
1
2

redis客户端连接redis

#redis客户端连接redis
docker exec -it redis /bin/bash
1
2

到此为止已经创建成功。

查看正在运行的容器

docker ps 
1

RedisDesktopManager连接redis

连接上，我们就可以我们在命令行设置的键值,key1:v1

此处只是以redis为例子，我们可以在docker容器中安装dubbo,mysql,nacos,rocketmq等等，可以高效的搭建本地开发环境。
