Problems on Windows
Manipulating directory of container in GitBash (MSYS2)
$ docker exec hix-local-server_db_1 ls /
# or with single quotes
$ docker exec hix-local-server_db_1 ls '/'
# or with double quotes
$ docker exec hix-local-server_db_1 ls "/"
ls: cannot access 'C:/Program Files/Git/': No such file or directory
The best alternative way to solve this problem is WSL integration.
Require two steps.
- Install Windows embedded Ubuntu 20.04.
- Change settings of Docker Desktop.
Using volume in GitBash (MSYS2)
