	~~= Problems on Windows =~~

	~~== Manipulating directory of container in GitBash (MSYS2) ==~~

	~~<source lang="bash">~~
	~~$ docker exec hix-local-server_db_1 ls /~~
	~~# or with single quotes~~

	~~The best alternative way to solve this problem is WSL integration.~~

	~~Require two steps.~~

	* Install Windows embedded Ubuntu 20.04.
