Docker cheatsheet

	1. Перезапустить контейнер с другими параметрами
	Есть такая утилита runlike - https://github.com/lavie/runlike/
	Запустив runlike -p <имяконтейнера>, вы получите готовую команду для запуска с теми же параметрами, которые были использованы изначально.
	Например, для какого-то тестового сервиса команда и вывод может выглядеть следующим образом:
	runlike -p testservice вернет
	docker run \
	--name=testservice \
	--user=test \
	-p 8015:8080 \
	--restart=always \

Commit message guidelines

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages
