this won't work. enable-cri was removed in 1.7.0

@matlockx But as I tested, adding a kube_version check for --enable-cri was enough to upgrade to 1.7.0 using upgrade-cluster (with default options).

interesting. i just tested it and kubelet service failed to start with 'Error: unknown flag: --enable-cri'. maybe you haven't changed the version to 1.7.0? because the check just excludes the block from being used if your version is still 1.6.* and on top of that it does not make sense to me to change the check like that. i think it should be something like

{% if kube_version | version_compare('v1.6', '>=') %} {# flag got removed with 1.7.0 #} {% if kube_version | version_compare('v1.7', '<') %} --enable-cri={{ kubelet_enable_cri }} {% endif %}

what does kubectl version say on your cluster.

see also https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG.md#server-binaries

@matlockx Alright. On my cluster kubectl version is 1.5.6 and you're right with your suggestion.

Thanks for reminding me 😀 !

Can I update the changes you suggested above?

sure. but i'm not a maintainer, so it has to go through review by one of them anyhow.

Okay @matlockx ! Just updated it.

Updated!!

Updated!

you forgot the closing endif, it must be:

{% if kube_version | version_compare('v1.6', '>=') %} {# flag got removed with 1.7.0 #} {% if kube_version | version_compare('v1.7', '<') %} --enable-cri={{ kubelet_enable_cri }} \ {% endif %} --cgroups-per-qos={{ kubelet_cgroups_per_qos }} \

anyhow, you should double check the file after the jinja2 replacements. i haven't checked it.

Thanks @matlockx for pointing this out.

you are welcome

@rsmitty i see, you got the ci super power :)

matlockx · 2017-07-10T10:10:07Z

ok, how do you read the ci result? https://gitlab.com/kargo-ci/kubernetes-incubator__kubespray/pipelines/9534059 says 'passed' but it still says here 'failed' and: any other suggestions regarding the change?

bradbeam · 2017-07-10T13:05:04Z

It's just the webhooks being dumb, CI passed

matlockx · 2017-07-11T08:25:03Z

can we merge this?
