# RBCS Docker images
There are 3 image flavours:
- vanilla
- memcache
- native

The `vanilla` image only contains the envelope 
jar file with no plugins and is based on `eclipse-temurin:21-jre-alpine`

The `memcache` image is similar to the `vanilla` image, except that it also contains
the `rbcs-server-memcache` plugin in the `plugins` folder, use this image if you don't want to use the `native`
image and want to use memcache as the cache backend

The `native` image contains a native, statically-linked executable created with GraalVM
that has no userspace dependencies. It also embeds the memcache plugin inside the executable.
Use this image for maximum efficiency and minimal memory footprint. 

## Which image shoud I use?
The `native` image uses Java's SerialGC, so it's ideal for constrained environment like containers or small servers,
if you have a lot of resources and want to squeeze out the maximum throughput you should consider the
`vanilla` or `memcache` image, then choose and fine tune the garbage collector.

Also the `native` image is only available for the `x86_64` architecture at the moment, 
while `vanilla` and `memcache` also ship a `aarch64` variant.
