Insufficient memory / CPU?

[aliakhtar]

My laptop has 60+ GB of ram, and a 4-core i7 cpu. But when I try to create a deployment using 1 cpu and 1Gi as the memory / cpu requests, I get told there's insufficient CPU and memory. What gives?

Ubuntu 16.04, virtualbox.

Hey,

The minikube VM is configured by default to only use 1gb of memory. You can pass more during minikube start with the --memory flag. Note that you'll need to stop/start minikube for this to take effect.

Thanks. And the CPU?

[dlorenc]

Same thing, we start with 1 CPU by default. --cpus= will get you more.

You can run minikube start -h to display this helptext

I'm 'guessing' that the memory is is specified in Mb but it would be useful to have that listed more clearly in the help text

Running:

minikube stop && minikube start --cpus 4 --memory 8192

in Minikube v0.14.0 does not change the capacity of kubectl describe nodes, which stays at cpu: 2, the current default. Maybe there is something else to recreate too?

minikube start --memory 4096
Does not increase the memory for my machine.

I am on a mac using virtualbox as a virtualisation-driver.

If i take a look in the virtualbox settings of the VM i can see that memory is still at 2gb.

Any idea?

@uschmann Was a minikube VM already running? If there is already a minikube VM running, the memory won't be changed as this is done on creation of the VM. You will have to run a minikube delete; minikube start --memory 4096 to have the increased memory. We have an issue tracking this here: #1147

@uschmann or to set as default you can do something like this and restart Minikube:
minikube config set memory <memory>

You do indeed have to delete before any edited config is reflected 😞

On OS/X Virtualbox, I found the minikube memory setting was having no effect. I had to change it in VB.

I did this on my mac

minikube stop
minikube delete
minikube --memory 8192 --cpus 2 start
