[Bug Report] ~ is not expand when using docker-compose

Describe the bug

I am using docker-compose to deploy v0.24.0 of mango. When I follow the steps in README and used the configuration file in the README.md file, I found that the config.yml file can be read normally, but the mango data folder is always empty.

When checking the log outputs, I found that the logs show that the ~/mango folder does not exist, then mango created a /~/mango directory instead of using the /root directory.

But when I replace ~ with /root in the config, mango can recognize that the directory exists and write data.

To Reproduce

mkdir config mango
vim config/config.yml
docker-compose up

Expected behavior

mango directory should not be empty

Environment (please complete the following information):

OS: Ubuntu 20.04 with docker.io and docker-compose installed.
