Not sure if this was best place to add a controller argument. cc @sdodson

Should be a list here: ['MountPropagation=false']. In any case, I don't think its needed, since its being set in l_node_kubelet_feature_flag_dict

It looks like we have moved node flags to openshift_node/defaults/main.yml but master still relies on openshift_facts and this is required by both master and node configs.
|
This has to be done via master and node config or just one of them? |
|
This has to be done in both. |

bot, retest this |

No need to stick this in it's own dictionary and also modify l2 dict below.
Just put this feature-gates in the openshift_node_kubelet_args_dict. Or, we should refactor the common bits out of openshift_node_kubelet_args_dict.
We need to disable mount propagation feature in openshift-ansible for now becaue it breaks private mounts. We are changing the defaults in upstream to revert the feature to old behaviour

@vrutkovs @michaelgugino addressed review comments. Also added a reason why need to disable this feature. |
|
@gnufied What do you mean 'for now' ? Just for a week, or for 3.10, or for the foreseeable future? Will this break any current deployments? Does anything rely on this feature that we are disabling? How are we accounting for upgrades? |
|
@michaelgugino None of the existing stuff should break if we disable the feature. In future - I would like to make this tunable so as user can turn this on and off. May be - we should do this right now. I will try and make it so |
