微服务轻量化容器技术相关同事分享的Docker学习汇总

Posted 2020-08-05

还没时间去练习：

1. Docker commands:
1. docker images (list all image on this host)
2. docker ps -a ( list all containers on this host)
3. docker run -t -i centos6_oodee /bin/bash ( create a container with command)
4. docker start 091a802729cd ( start one instance of the container).
5. docker attach 091a802729cd (login the instance)
2. Learn about Virtualization and Containers

https://azure.microsoft.com/zh-cn/blog/containers-docker-windows-and-trends/

2. Docker

https://www.docker.com/

https://docs.docker.com/engine/understanding-docker/

https://github.com/wsargent/docker-cheat-sheet

https://hub.docker.com/

 

4. Tips to install Docker on Windows
1.  Docker only support 64-bit system and for windows Virtualization Technology must be enabled.

                -To Enable VT,  it should be enabled in Bios (HP: Press F10,  password : gE51sFqc , Advanced-> Device Configuration)

1. For Windows sitting behind a corporate proxy, docker init cannot work properly.

I got mine to work by adding HTTP_PROXY and HTTPS_PROXY with the correct proxy value into my "System variables" under Environment Variables dialog.

 

5. Private Docker registry in Nokia

FQDN: docker-registry.eecloud.nsn-net.net

6. 延伸阅读

      7. 使用Dockerfile来启动sshd：

            7.1 创建Dockerfile,  基于基线image：centos6_oodee，在build新image时，执行如下命令： /usr/sbin/sshd && /bin/bash，这样新image在启动时就可以加载sshd。

                内容如下：

                FROM centos6_oodee

            ENTRYPOINT /usr/sbin/sshd && /bin/bash

         7.2在Dockerfile所在目录执行：

docker build -t centos6_oodee_with_sshd .

         7.3创建container：

docker run -t -i centos6_oodee_with_sshd &

         7.4 docker start container后 docker attach 上去top即可看到sshd 已经开启。
