Removing Taint from kubernete nodes doesnot work
Ubuntu 18.04
Kubernete on JUJU
I tried to remove the taint form nodes: kubectl get nodes -o json | jq .items[].spec.taints
[ { "effect": "NoSchedule", "key": "", "timeAdded": "2019-06-12T20:38:52Z" }
]
[ { "effect": "NoSchedule", "key": "", "timeAdded": "2019-06-12T20:38:57Z" }
]
[ { "effect": "NoSchedule", "key": "", "timeAdded": "2019-06-12T20:39:00Z" }
]
with this command:
kubectl patch node juju-06819a-0-lxd-70 -p '{"spec":{"taints":[]}}'
node/juju-06819a-0-lxd-70 patched
rastin@cloudrnd1:~/.kube$ kubectl patch node juju-06819a-0-lxd-71 -p '{"spec":{"taints":[]}}'
node/juju-06819a-0-lxd-71 patched
rastin@cloudrnd1:~/.kube$ kubectl patch node juju-06819a-0-lxd-72 -p '{"spec":{"taints":[]}}'
node/juju-06819a-0-lxd-72 patched
Nothing happened all the taint still there!

I found the solution here with little bit of change:
On the machine which I have the LXDs I changed the profile to use 'dir' :
name: juju-##MODEL##
config: boot.autostart: "true" linux.kernel_modules: ip_tables,ip6_tables,netlink_diag,nf_nat,overlay raw.lxc: | lxc.apparmor.profile=unconfined lxc.mount.auto=proc:rw sys:rw lxc.cap.drop= security.nesting: "true" security.privileged: "true"
description: ""
devices: aadisable: path: /sys/module/nf_conntrack/parameters/hashsize source: /dev/null type: disk aadisable1: path: /sys/module/apparmor/parameters/enabled source: /dev/null type: disk
Then I applied this profile to my LXC:
sudo lxc profile assign <container-name> default
Profiles default applied to <container-name>
You can get 'container-name' by running : $lxc list
Then I restarted all containers:
$sudo lxc restart --all
Now all nodes are ready :
$kubectl get nodes
NAME STATUS ROLES AGE VERSION
container#1 Ready <none> 6d v1.14.2
container#2 Ready <none> 6d v1.14.2
container#3 Ready <none> 3d v1.14.2
