We now have better explanations on labels and selectors.
The kubectl run section was getting very long, so now
it is different parts: kubectl run basics; how to create
other resources like batch jobs; first contact with
labels and annotations; and showing the limitations
of kubectl logs.
Revamp most of the Helm content:
- overview of Helm moved to helm-intro.md
- explanation of chart format in helm-chart-format.md
- the very crude chart example is now in helm-create-basic-chart.md
- the more advanced chart (with templates etc) is now in helm-create-better-chart.md
- deep dive into Helm internals (how it stores it's data) in helm-secrets.md
This is all for Helm 3. Helm 2 is not supported anymore.
Use Replicated Ship to generate the base and overlays
from the kubercoins GitHub repo.
The namespaces chapter has been slightly tweaked so
that we can use it for either Helm or Kustomize demo.
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.
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.
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
- added self-paced manifest for intro workshop
- refactored intro content to work for all workshops
- fixed footnote CSS to work in all contexts
- intro+logistics content is good to go
