docker高效搭建本地开发环境

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

安装Docker所需要的一些工具包

sudo yum install -y yum-utils

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

启动docker

sudo systemctl start docker

常用的docker命令

 docker attach      ##Attach local standard input, output, and error streams to a running container
 docker build       ##Build an image from a Dockerfile
 docker commit      ##Create a new image from a container's changes
 docker cp          ##Copy files/folders between a container and the local filesystem
 docker create      ##Create a new container
 docker diff        ##Inspect changes to files or directories on a container's filesystem
 docker events      ##Get real time events from the server
 docker exec        ##Run a command in a running container
 docker export      ##Export a container's filesystem as a tar archive
 docker history     ##Show the history of an image
 docker images      ##List images
 docker import      ##Import the contents from a tarball to create a filesystem image
 docker info        ##Display system-wide information
 docker inspect     ##Return low-level information on Docker objects
 docker kill        ##Kill one or more running containers
 docker load        ##Load an image from a tar archive or STDIN
 docker login       ##Log in to a Docker registry
 docker logout      ##Log out from a Docker registry
 docker logs        ##Fetch the logs of a container
 docker pause       ##Pause all processes within one or more containers
 docker port        ##List port mappings or a specific mapping for the container
 docker ps          ##List containers
 docker pull        ##Pull an image or a repository from a registry
 docker push        ##Push an image or a repository to a registry
 docker rename      ##Rename a container
 docker restart     ##Restart one or more containers
 docker rm          ##Remove one or more containers
 docker rmi         ##Remove one or more images
 docker run         ##Run a command in a new container
 docker save        ##Save one or more images to a tar archive (streamed to STDOUT by default)
 docker search      ##Search the Docker Hub for images
 docker start       ##Start one or more stopped containers
 docker stats       ##Display a live stream of container(s) resource usage statistics
 docker stop        ##Stop one or more running containers
 docker tag         ##Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE
 docker top         ##Display the running processes of a container
 docker unpause     ##Unpause all processes within one or more containers
 docker update      ##Update configuration of one or more containers
 docker version     ##Show the Docker version information
 docker wait        ##Block until one or more containers stop, then print their exit codes

以安装redis为例

启动docker

#启动docker
sudo systemctl start docker

查看镜像

#查看镜像
docker images

查看redis版本

#查看软件的版本
$ docker search  redis

获取最新的版本redis

#获取最新的版本
docker pull redis:latest

查看是否下载成功

docker images

启动redis

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

redis客户端连接redis

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

到此为止已经创建成功。

查看正在运行的容器

docker ps 

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。
