Error adding node - Githubissues

powerdu91 commented 5 months ago

What happened?

servername	IP	hardware	role
k8s-master01	192.168.202.130/24	4C4G40G	master
k8s-master02	192.168.202.131/24	4C4G40G	master
k8s-master03	192.168.202.132/24	4C4G40G	master
k8s-woker01	192.168.202.133/24	4C4G40G	worker
k8s-woker02	192.168.202.134/24	4C4G40G	worker
kubespray	192.168.202.135/24	4C4G40G	ansible

I successfully created the k8s cluster and then deleted node node5. The command is: Ansible playbook - i inventory/cluster/hosts. yaml -- come -- come user=root remove node. yml - v - b -- extra vars "node=node5". Afterwards, I added node5 node and the command was: Ansible playbook - i inventory/cluster/hosts. yaml -- come -- come user=root scale. yml - v - b -- limit=node5 Errors that occurred:

The conditional check 'download.enabled' failed. The error was: error while evaluating conditional (download.enabled): {{ download_defaults | combine(item.value) }}: 'item' is undefined. 'item' is undefined. {{ download_defaults | combine(item.value) }}: 'item' is undefined. 'item' is undefined

The error appears to be in '/root/kubespray/roles/download/tasks/main.yml': line 19, column 3, but may be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

name: Download | Download files / images ^ here

TASK [download : Download | Download files / images]

What did you expect to happen?

Under normal circumstances, a new node will be successfully added

How can we reproduce it (as minimally and precisely as possible)?

ansible-playbook -i inventory/mycluster/hosts.yaml --become --become-user=root scale.yml -v -b --limit=node5
