The satellite exemption was justified with the claim that a container memory limit shrinks the JVM heap, on the grounds that a container-aware JVM reads memory.max to size it. That is not what this JVM does. linstor-server's build.gradle sets jvmSatelliteOpts to "-Xms32M", "-Xmx2G", "-XX:+CrashOnOutOfMemoryError" and hands it to the generated Satellite start script via defaultJvmOpts; the controller gets -Xmx8G by the same route. An explicit -Xmx means the JVM never consults memory.max for heap sizing, because container awareness only picks a default maximum when -Xmx is absent. LINSTOR_VERSION in the package Makefile pins which linstor-server that is, and images/piraeus-server/Dockerfile builds it. So a limit caps RSS and nothing else, which makes the removed limits.memory of 2Gi the wrong number rather than merely a tight one: 2Gi is exactly -Xmx2G, leaving nothing for metaspace, thread stacks, code cache, GC structures and direct buffers, so a satellite growing into its own heap ceiling would be OOM-killed by the kernel before the JVM got there. The 4Gi LimitRange default clears the 2G heap with room left for non-heap rather than "deriving a capped heap", and what a fitted per-chart limit still needs is a measured peak on a high-resource-count cluster, not an explicit heap share, which already exists. Comments only; no rendered output and no assertion changes. Assisted-by: LLM Signed-off-by: Myasnikov Daniil <myasnikovdaniil2001@gmail.com>
Cozystack
Cozystack is a free and open-source platform and framework for building clouds.
Cozystack is a CNCF Sandbox project that was originally built and sponsored by Ænix.
With Cozystack, you can transform a bunch of servers into an intelligent system with a simple REST API for spawning Kubernetes clusters, Database-as-a-Service, virtual machines, load balancers, HTTP caching services, and other services with ease.
Use Cozystack to build your own cloud or provide a cost-effective development environment.
Use-Cases
-
Using Cozystack to build a public cloud
You can use Cozystack as a backend for a public cloud -
Using Cozystack to build a private cloud
You can use Cozystack as a platform to build a private cloud powered by Infrastructure-as-Code approach -
Using Cozystack as a Kubernetes distribution
You can use Cozystack as a Kubernetes distribution for Bare Metal
