In the Kubernetes courses, it takes a bit too long before we
reach the Kubernetes content. Furthermore, learning how to
scale with Compose is not super helpful. These changes
allow to switch between two course flows:
- show how to scale with Compose, then transition to k8s/Swarm
- do not show how to scale with Compose; jump to k8s/Swarm earlier
In the latter case, we still benchmark the speed of rng and
hasher, but we do it on Kuberntes (by running httping on
the ClusterIP of these services).
These changes will also allow to make the whole DaemonSet
section optional, for shorter courses when we want to
simply scale the rng service without telling the bogus
explanation about entropy.
This was a request by @abuisine, so I'm flagging him for review :-)
This section explains the challenges associated with self-hosting
the control plane; and segues into static pods. It also mentions
bootkube and the Pod Checkpointer. There is an exercise showing
how to run a static pod.
kube-fullday is now suitable for one-day tutorials
kube-twodays is not suitable for two-day tutorials
I also tweaked (added a couple of line breaks) so that line
numbers would be aligned on all kube-...yml files.
I've dispatched the new content so that the fullday training
(actually two days, don't let the file name distract you)
is broken down in 8 chapters of approximately equal lengths,
where the most complex content is preferably located at the
end of the chapter (to allow people to catch up and ask questions
during breaks) + 1 chapter with the what's next / links / thank you
slides
This was discussed and agreed in #246. It will probably break a few
outstanding PRs as well as a few external links but it's for the
better good long term.
We have two extra variables in the slides:
@@GITREPO@@ (current value: github.com/jpetazzo/container.training)
@@SLIDES@@ (current value: http://container.training/)
These variables are set with gitrepo and slides in the YAML files.
(Just like the chat variable.)
Supercedes #256
