Write a guide for setting up Agones with taints and tolerations

[markmandel]

We should write a guide for setting up Agones with taints and toleration, so that Agones (and likely prom + grafana, if you are running them) are on their own machine(s), and gameservers run on their on machines -- and never the two shall meet.

This is how people should run it in production, so we should make it easy with a tool.

Stretch Goal: Make our build tooling do this by default on GKE.

[markmandel]

Flip side - our build tooling already does this, and it's part of our helm template. But we just need to write the documentation.

@jkowalski I've never played with this stuff, from memory, you did this work, yes?

[markmandel]

We have this section here:
https://agones.dev/site/docs/installation/helm/#installing-the-chart

Does that mean we can close this ticket?

@jkowalski you wrote this section - wdyt?

[markmandel]

Closing this now. We can reopen / create a new ticket if this comes up again.

Actually, looks like i didn't hit the close button. But it seems like we should move the taints and tolerations docs from here here in the helm command into a central place like installation maybe?

[roberthbailey]

I've moved the instructions to the installation page along with the example of how to do it on a GKE cluster. I don't have an easy way to test EKS / AKS and the directions don't apply to minikube which has only a single node.

How do folks feel about closing this (or moving it out of the 1.0 milestone)? Or if anyone can provide similar updates to configure EKS / AKS prior to the next release that'd be even better.

[markmandel]

I was thinking about this - I think I would feel comfortable closing this, if the section

By default Agones prefers to be scheduled on nodes labeled with stable.agones.dev/agones-system=true and tolerates the node taint stable.agones.dev/agones-system=true:NoExecute. If no dedicated nodes are available, Agones will run on regular nodes, but that’s not recommended for production use.

Was hosted up in the install section (or somewhere near it) at the top, rather than buried in the GKE section.

At least then we are explaining what needs to be done for all installations, but not providing examples (yet).

WDYT?

[roberthbailey]

That sounds like a great idea. I'll send a PR over to move it up and slightly reword the GKE section to close this out.
