1ba3acab98 Drain: allow pods grace period to terminate 
The default of 0 is taken as "delete immediately", which is
not appropriate.

7091debe23 Make lint happier 
Without this, golint is complaining about a few cosmetic changes.
This solves it, and is necessary if we want to add a lint test
in CI.

b0bd603931 fix: Follow DKL-DI-0004 guideline 
Without this patch, we need to build a cache, remove it.
Since apk allows to work with no-cache and won't leave artifacts,
we should use it.

This will make the dockle best practices scanner happier.

16109017ce Prepare for k8s release 1.19 (Aug 25) 
This is #152, #139, #127 in disguise.

	Maybe this time let it simmer a bit longer until the k8s
	release is there?
 2020-08-19 17:30:00 +02:00
Daniel Holbach
8fafad18bb Revert #139 
This is a follow-up to #150, so we can get a 1.4.x release
	out that will be geared towards k8s 1.1[6-8].

	Update to latest 1.17 kubectl: 1.17.7.

8e73cf224d Revert parts of #127, move to client-go/kubectl 1.17 
After the release of kured 1.4.0 we should be able to go back.

	This was decided in our meeting
(https://docs.google.com/document/d/1bsHTjHhqaaZ7yJnXF6W8c89UB_yn-OoSZEmDnIP34n8/edit#heading=h.8cgszb6vuhza)

	Let's go with supporting 1.1[678] in this release.

bdd20c963c Unpin base docker images 
The upside is that image building will always use the latest
stable version of the alpine OS, which might include security fixes.
The downside is that it's less reproducible, because the full
version isn't given.

While this commit isn't necessary per se, it's nice to have
an image that will be up to date, when we'll build it.
