CPU & Memory Formats

Satusky uses Kubernetes resource quantities.

Current deploy behavior

Input	Backend field
--cpu / app.cpu	CPU request
--memory / app.memory	Memory request and memory limit

There is no separate CPU limit flag and no separate memory limit flag today.

Defaults:

Field	Default
CPU	0.5
Memory	256Mi

CPU

Accepted examples:

Value	Meaning
100m	0.1 core
250m	0.25 core
0.5	0.5 core
1	1 core
2	2 cores

Memory

Memory values must include a unit. Use Mi or Gi.

Value	Meaning
128Mi	128 mebibytes
256Mi	256 mebibytes
512Mi	512 mebibytes
1Gi	1 gibibyte
2Gi	2 gibibytes

--memory 512 is rejected because Kubernetes would interpret a bare number as bytes.

HPA and VPA

HPA targets are percentages:

1ctl deploy --hpa --hpa-cpu-target 70 --hpa-memory-target 80

VPA bounds use resource quantities:

1ctl deploy --vpa --vpa-mode Off --vpa-min-cpu 100m --vpa-max-cpu 2 --vpa-min-memory 128Mi --vpa-max-memory 2Gi
