@bwagner5 @jaypipes @kishorj Can you please review. Currently it is blocking us to use taints on EKS nodes.

Any update on this ? It would help to have this in place for our EKS systems

@jaypipes @bwagner5 @kishorj Please review this, I need this too, in my case, all nodes have tolerations, so the daemonset is scaled to 0. This is just a small PR and should be easy to merge without any negative impact.

@chmoon93 sincere apologies for the long delay in reviewing and merging this. looks great to me.

@jaypipes thanks for your quick response, now I've tried to use it, but the CircleCI pipeline says:

/home/circleci/project/scripts/publish-charts.sh
/home/circleci/project/scripts/publish-charts.sh: line 11: CIRCLE_TAG: unbound variable
Not a valid semver release tag! Skip charts publish

Is this expected? If yes, when can I expect this to be released? I need to roll this out and if it's not in the repository, I will have to download the chart for now. A quick update when I can expect this to be published would be great, thanks in advance!

Edit: I've already figured, no tag has been set to v0.0.69, not sure if by accident or if the release schedule is fixed. I will download the chart for now and keep an eye on it.

Looks like there's some bug in our release automation... I will check with @bwagner5 and @jayanthvn and figure it out.

@jaypipes thanks again, right now I've got the agents running with the downloaded chart, works perfectly, will update as soon as a tag is pushed. I think above is not a bug, but expected behavior, see edit on my old comment.

Anyway, since this is already working, maybe you want to close the duplicate PRs here: #585 and #540
