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 Native Image
that has no userspace dependencies. It also embeds the memcache plugin inside the executable.
Use this image for maximum efficiency and minimal memory footprint.
The jlink image contains a custom Java runtime created with GraalVM's Jlink
that only depends on glibc. It also contains the memcache plugin in the module path.
Use this image for best performance.
Which image should 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.
