Although I am a beginner, I will continue to build an environment such as a laptop computer, so I will take notes. Vagrant 2.2.14 Ubuntu 14.04.6 LTS Docker version 1.6.2
When I was studying, I executed the command used by the instructor and got an error. It doesn't go according to the video. When I looked it up, my environment was old. Docker commands have changed. Version UP requires upgrading from Ubuntu 14.04.6 LTS on Vagrant to Ubuntu 16.04.7 LTS. OS update
I updated from Ubuntu 14.04 LTS to 16.04.6 LTS Upgrade with reference to If I thought I would upgrade the Docker version separately, I could upgrade together. The latest is Dcoker version 18.09.7
You can now run the new Docker command.
I want to use VS Code on Vagrant, so I need to install and configure VS code.
Set the installation by referring to "Editing files on Vagrant with VS Code" For Windows.
