It is troublesome to build the environment, and it is troublesome to drop or install the ISO for the virtual environment. Since it's called vagrant, it seems that you can easily create a virtual environment. When you are thinking about what to do with Hyper-V or VM ware I heard about docker, so I decided to put it in for the time being.

The word "containerization" is used. Since it is troublesome to bother to allocate resources, I put docker in Windows and studied containers.

If you have any problems, I wonder if you should ask quora (https://jp.quora.com/).

goal

Launch ubuntu with docker

Installation

https://www.docker.com/why-docker

Click Download Docker Desktop
Click Docker Desktop for windows
Click Get Stable ・・・ 407MB download ・・・ It is heavy after all. In my garbage-like network environment, it takes 5 minutes to download.
OK click
Waiting for installation (takes time)
Windows restart
I got an error after rebooting. It seems that the Linux kernel is not installed.
docker can create a container that runs ubuntu, nginx, nodejs, etc., but it recognizes that it needs a Linux kernel to run it.
https://aka.ms/wsl2kernel/
Download and install the WSL2 Linux kernel update wsl_update_x64.msi from the link.
By the way, enable the Linux kernel and virtual machine functions. The following command. (Reference: https://docs.microsoft.com/ja-jp/windows/wsl/install-win10

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

Start docker

ubuntu installation

I don't expect to raise the image I made, so I won't create a docker HUB account. Create and operate a container according to the following flow while using PowerShell or command prompt

DL command for ubuntu image
Container creation command
Container operation command

Check if there is an image in docker

docker images

DL image of ubuntu

docker pull ubuntu

Create docker container

docker run -it --name test ubuntu

Show list of containers

docker ps -a

Stop container

docker stop test

Start of container

docker start test

Enter the container and type the command

docker exec -it test bash

Delete container

docker rm test

I could use ubuntu.

Neither ʻifconfig nor ʻip address show could be used. You need to be clear about what you can do with the image.

Summary

I understand the rough commands of docker. For the time being, remember pull, run, ʻexec, start, stop`.
It has been decided that the image that has been dropped can and cannot be done.

Until you build the docker environment and start / stop the Ubuntu container
