Instead of Ubuntu 18.04, we should use 22.04 (especially as
18.04 will be EOL soon). This moves a few providers to 22.04
(and more will follow).
We now ship a small containerd configuration file (instead
of defaulting to an empty configuration like we did before)
since it looks like recent versions of containerd cause
infinite crashloops if the cgroups driver isn't set properly.
Also, Linode is now provisioned using Terraform (instead of
the old-style system relying on linode-cli) which should make
instance provisioning faster (thanks to Terraform parallelism).
The "wait" command now tries to log in with both "ubuntu" and
"root", and if it fails with "ubuntu" but succeeds with "root",
it will create the "ubuntu" user and give it full sudo rights.
Finally, a "standardize" action has been created to gather all
the commands that deal with non-standard Ubuntu images.
Note that for completeness, we should check that all providers
work correctly; currently only Linode has been validated.
It is now possible to set the user login (instead of
having it hardcoded to "docker"). Also, various actions
have been broken out in separate functions to facilitate
future maintenance.
The settings file can now specify an optional list of steps.
After creating a bunch of instances, the steps are then
automatically executed. This helps since virtually all
deployments will be a sequence of 'start + deploy + otheractions'.
It also helps to automatically excecute steps like webssh
and tailhist (since I tend to forget them often).
Many improvements. QR code, fixed page size, better
use of page estate, etc.
Also pdfkit should kind of work now (not quite using
the full page size, but at least it's not utterly
broken like before).
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 allows to manage groups of VMs across multiple infrastructure
providers. It also adds support to create groups of VMs on OpenStack.
WARNING: the syntax of workshopctl has changed slightly. Check READMEs
for details.
Bump up Compose and Machine to latest versions.
Bump down Engine to stable branch.
I'm pushing straight to master because YOLO^W^W
because @bridgetkromhout is using the kube101.yaml
file anyway, so this shouldn't break her things.
(Famous last words...)
