[enhancement] create cache directory if it doesn't exist

[onedr0p]

I would like Gonic to create the cache directory if it doesn't exist

2021/03/22 19:05:33 starting gonic v0.12.2
2021/03/22 19:05:33 provided config
2021/03/22 19:05:33     cache-path      /data/cache
2021/03/22 19:05:33     config-path
2021/03/22 19:05:33     db-path         /data/gonic.db
2021/03/22 19:05:33     genre-split

2021/03/22 19:05:33     jukebox-enabled false
2021/03/22 19:05:33     listen-addr     :80
2021/03/22 19:05:33     music-path      /media-serenity/Library/Music
2021/03/22 19:05:33     podcast-path    /media-serenity/Library/Podcasts
2021/03/22 19:05:33     proxy-prefix
2021/03/22 19:05:33     scan-interval   120
2021/03/22 19:05:33     version         false
2021/03/22 19:05:33 please provide a valid cache directory

For now I have to use an initContainer to create the directory before the container starts

hey,
not sure if this is a kubernetes thing,
but gonic has no logic for creating any of the root folders it's expecting (eg cache, music, podcasts)

at least in dockerland, when provide host->container mounts docker creates the host folders for you (in this example the /tmp/g_* folders didn't exist)

perhaps there is a similar way in kubernetes?

👋 No problem, I have it solved as I mentioned above.

I'm trying to put the cache directory under /data. However when the application is first created /data/cache does not exist. Putting the cache directory here makes it much easier to maintain because I'll only need 1 gonic app volume for everything besides the media share.
