Reconsider CLI defaults

[fernando-villalba]

Issue

Creating a cluster with civo kubernetes create creates a cluster with defaults. This is phenomenal use of convention over configuration so the user doesn't need to input too many flags or commands to create a cluster.

However we should perhaps reconsider the defaults used here, right now this is what it does:

1. Create a cluster with 3 g4s.kube.medium nodes --> We should probably make the g4s.kube.xsmall the default. 3 nodes may be okay, although perhaps 2 is more conservative.
2. Randomly pick a name for the cluster --> This is phenomenal, no need to change
3. Randomly pick a Linux distro for cluster --> I don't think this is a good thing as it changes the nature of the cluster too much.
4. Create a firewall/s for the cluster --> This is also okay, but cluster deletion should clean these, or at least provide an option to do so. Will create another ticket for this.

(Not sure if I am missing other defaults)

In addition, the UI should be aligned with the defaults the CLI provides.

Acceptance Criteria

1. Reconsider changing the defaults to create a cluster that's as cheap as possible for generalised workloads.
2. Make the OS deterministic, don't randomize it.

Cluster defaults should be

• As secure as possible.
• As cheap as possible.
• Catering to general needs of the public wishing to test a cluster or use for quick, simple workloads. We perhaps shouldn't assume that the defaults are for heavy workloads, or even for production workloads as in those scenarios a user may want more fine grained settings
• The nature of the cluster should be predictable, randomizing the OS prevents that.

Another option could be to create templates for different types of configs, for example:

• ML
• Production
• Test
• Budget
• Etc

But this is out of the scope of this ticket.

Hi Team,

I have addressed several aspects of this issue:

Set the default node size to g4s.kube.xsmall Set the default number of nodes to 2 Ensured firewall rules are correctly applied during cluster creation However, I was unable to find a way to make the OS selection deterministic. There doesn't seem to be any mention of this in the API documentation. Could you provide guidance on how to achieve this?
