Docker版本说明

参考官网： Docker Engine 的版本号范围: 0.1.0 ~ 1.13.1。 新的版本变更为 Docker CE or Docker EE.

在 2017 年 3 月 2 日, docker 团队宣布

企业版 Docker Enterprise Edition ( EE ) 发布.免费的 Docker Engine 改名为 Docker Community Edition ( CE )

并且采用基于时间的版本号方案.

Docker EE 和 Docker CE 第一个采用新的版本号方案的版本为17.03 。

Docker CE 的两个版本

Stable 每个季度提供可靠更新Edge 每个月提供新功能

Docker安装

官方指导文档： 17.12的版本

Step1. Set up the Repository

Step2. Enable the nightly or test repositories（Optional）

可以选择是否开启edge和test仓库,这里调过操作

Step3. INSTALL DOCKER CE

这里我们选择第二种方式，来安装特定版本的docker ce

Step5. Verify that Docker CE

运行hello-world镜像来测试是否安装成功,本地没有镜像时会自动从docker hub中下载,当出现Hello from Docker!即表示安装成功

[root@artisan ~]# docker run hello-world Unable to find image 'hello-world:latest' locallylatest: Pulling from library/hello-world1b930d010525: Pull complete Digest: sha256:2557e3c07ed1e38f26e389462d03ed943586f744621577a99efb77324b0fe535Status: Downloaded newer image for hello-world:latestHello from Docker!This message shows that your installation appears to be working correctly.To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal.To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID: more examples and ideas, visit: ~]#

访问 默认用户名和密码为 guest

RabbitMQ默认账户密码为guest/guest，如果不想使用默认密码，可在启动容器时设置​​-e RABBITMQ_DEFAULT_USER=user -e RABBITMQ_DEFAULT_PASS=password​​ ,换成想要的用户名和密码即可。

docker run -d --hostname my-rabbitmq -p 5672:5672 -p 15672:15672 -e RABBITMQ_DEFAULT_USER=user -e RABBITMQ_DEFAULT_PASS=password rabbitmq:3.7.8-management
