Defaults for start arguments?

[joelpittet]

Is there a way (like dotfile) for colima to specify the --memory --cpu flags instead of doing that each time?

Instead of typing:
colima start --cpu 4 --memory 8
I could do something like
colima start
And it would read from ~/.colima/config.yml or something with:

cpu: 4
memory: 8

Not sure if this is a question or a feature request ;)

I've been confused about what arguments are only useful for first launch, and which must be done later.

For example, if you start the first time with colima start --disk=100 --cpu 4 --memory 8 then does colima start without arguments later just use all 3 of those? I know it uses --disk because that can't be changed. But I've never been clear about other things.

And what about --dns which seems to be important right now?

Thanks!

I agree that the documentation can be better in this regard. However, proper config file support is in the works.

And what about --dns which seems to be important right now?

DNS does not persist, it needs to be specified on each startup.

How about --cpu and --memory - do they persist?

Yeah they all persist, --dns is the exception.

This is actually specified in colima start --help.

$ colima start --help
Start Colima with the specified container runtime (and kubernetes if --with-kubernetes is passed).
The --runtime, --disk and --arch flags are only used on initial start and ignored on subsequent starts.

Thanks! That always scrolled off the screen for me :) So only --disk really. So I've probably been messing up by not always specifying --memory

Yeah, you can always customize an existing VM with the exception of disk size as stated here https://github.com/abiosoft/colima#customization-examples.

• modify an existing VM to 4CPUs and 8GiB memory.

colima stop
colima start --cpu 4 --memory 8

Hmm, you said in #242 (comment) "They all persist, DNS is the exception"

So the doc says
The --runtime, --disk and --arch flags are only used on initial start and ignored on subsequent starts

but you're saying that if you use --memory 6 --cpu 4 on the first start, those also persist (but can be overridden)?

Yes :) I can now see how this gets easily confusing.
