Core Sizing
How to determine what size machine or VM you need…
Core is made up of many different docker containers working in concert to build Core. Here is the information you need to figure out what size machine or VM you need for your Core.
Core Mini(mum)
Every Core gets the following installed automatically to provide services for other packages:
- PowerDNS
- PowerDNSmysql
- PowerDNSadmin
- Traefik
- Postgresql
- LDAP
- Authelia
- Dashboard
- Panel
- Roundcube

Note:
These memory numbers are “at rest”. You will likely need more depending on usage and load. Disk storage numbers are NOT given because they vary widely. CPU numbers are also not given since most clouds have a “regular” relationship between memory and CPU cores. There are services such as “pdnsmysql”, for example, that are used by many different applications. You only need to account for one use.
