The last 5(ish) times I presented DockerCoins, I ended up
explaining it slightly differently. While the application
is building, I explain what it does and its architecture
(instead of watching the build and pointing out, 'oh look
there is ruby... and python...') and I found that it
worked better. It may also be better for shorter
workshops, because we can deliver useful information
while the app is building (instead of filling with
a tapdancing show).
@bretfisher and @bridgetkromhout, do you like the new
flow for that section? If not, I can figure something
out so that we each have our own section here, but I
hope you will actually like this one better. :)
Committing straight to master since this file
is not used by @bridgetkromhout, and people use
that file by cloning the repo (so it has to be
merged in master for people to see it).
HASHTAG YOLO
We have images on the Docker Hub for the various components
of dockercoins. Let's add one slide explaining how to use that,
for people who would be lost or would have issues with their
registry, so that they can catch up.
In some cases, I would like Prometheus to be pre-installed (so that
it shows a bunch of metrics) without relying on people doing it (and
setting up Helm correctly). This patch allows to run:
./workshopctl helmprom TAG
It will setup Helm with a proper service account, then deploy
the Pormetheus chart, disabling the alert manager, persistence,
and assigning the Prometheus server to NodePort 30090.
This command is idempotent.
kubectl run is being deprecated as a multi-purpose tool.
This PR replaces 'kubectl run' with 'kubectl create deployment'
in most places (except in the very first example, to reduce the
cognitive load; and when we really want a single-shot container).
It also updates the places where we use a 'run' label, since
'kubectl create deployment' uses the 'app' label instead.
NOTE: this hasn't gone through end-to-end testing yet.
For each concept that is present in the full-length tutorial,
I added a link to the corresponding chapter in the final section,
so that people who liked the short version can get similarly
presented info from the longer version.
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.
