'keys' does not handle special keys (like ^J) anymore.
Instead, we should use `key`, which will pass its entire
argument to tmux, without any processing. It is therefore
possible to do something like:
```key ^C```
Or
```key Escape```
Most (if not all) calls to special keys have been
converted to use 'key' instead of 'keys'.
Action ```copypaste``` has been deprecated in favor
of three separate actions:
```copy REGEX``` (searches the regex in the active pane,
and if found, places it in an internal clipboard)
```paste``` (inserts the content of the clipboard as
keystrokes)
```check``` (forces a status check)
Also, a 'tmux' command has been added. It allows to
do stuff like:
```tmux split-pane -v```
The old version was using a slightly confusing way to
show which pods were receiving traffic:
kubectl logs --tail 1 --selector app=rng
(And then we look at the timestamp of the last request.)
In this new version, concepts are introduced progressively;
the YAML parser magic is isolated from the other concerns;
we show the impact of removing a pod from load balancing
in a way that is (IMHO) more straightforward:
- follow logs of specific pod
- remove pod from load balancer
- logs instantly stop flowing
These slides also explain why the DaemonSet and the
ReplicaSet for the rng service don't step on each other's
toes.
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.
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.
