MicroService_Architecture

For VirtualBox use *_virtualBox folders

Util

Stop and remove all containers

docker stop $(docker ps -qa)
docker rm $(docker ps -qa)

Screen

sudo apt update
sudo apt install screen

screen -ls

screen -r <id>

Ctrl-a c — создать новое окно Screen
Ctrl-a n — переместиться в следующее окно
Ctrl-a p — переместиться в предыдущее окно
Ctrl-a d — отключиться от текущей сессии screen, при этом все команды продолжат свое выполнение
Ctrl-a K — «убить» выбранное окно (нужно если программа в окне зависла и не хочет умирать самостоятельно)
Ctrl-a " — вывести список всех окон
Ctrl-a A — изменить название текущего окна (удобно, чтобы различать окна между собой, например поставить названия «localhost», «ssh 1.2.3.4» и т.п.

Git

sudo apt update
sudo apt install git

git clone https://github.com/KozinOleg97/MicroService_Architecture
