Instead of upgrading from 1.16 to <latest> we upgrade from 1.15
to 1.16, because upgrading from <latest-1> is a special case and
it is better to show the general case.
Also, the script that sets up admin clusters now has some retry
logic to accommodate hiccups in pssh or in the cloud provider.
- Kubernetes binaries installed for ops labs bumped up to 1.17.2
- Composed-based control plane bumped up to 1.17.2
- kuberouter now uses apps/v1 DaemonSet (compatible with 1.16+)
- disable containerd (cosmetic)
Autopilot can now continue when errors happen, and it writes
success/failure of each snippet in a log file for later review.
Also added e2e.sh to provision a test environment and start
the remote tmux instance.
Installing `mosh` via Homebrew may change `/usr/local/bin/python` to
Python 2. Adds docs to check and fix this so that `pyyml` and `jinja2`
can be installed.
Most parameters used by the Jinja template for the cards
can now be specified in settings.yaml. This should make
the generation of cards for admin training much easier.
This helps when the customer's internet connection filters out
the default port range. It still requires to have a port range
open somewhere, though. here we use 10000-10999, but this should
be adjusted if necessary.
Indicate clearly if we expect people to deploy
Prometheus or not. Explain better what the Helm
deployment does. Add a conclusion slide about
Grafana dashboards.
Prometheus deployment with Helm now stores
correctly Helm files in ~docker instead of
~ubuntu.
This will be used for kubernetes admin labs, to upgrade
an existing cluster. In order to be able to perform an
upgrade, we need a cluster running an older version.
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.
This adds a few features:
- ./workshopctl kubereset TAG (closes#306)
- remove python-setuptools (prepare for #353)
- ./workshopctl weavetest TAG (help detecting weave issues
like we had at OSCON, July 2018)
- remove a bit of dead code
