I have the following in one of my playbooks:

- name: “Copy SSH keys”  
command: sshpass -f ~/temp.pass ssh-copy-id -i ~/.ssh/id\_rsa.pub {{ ansible\_user }}@{{ item }}  
with\_flattened:
- groups.worker
- groups.proxy  
when: item not in groups.master

with the inventory file:

[master]  
9.42.23.241 kubelet\_extra\_args=‘[“–eviction-hard=memory.available\<100Mi,nodefs.available\<2Gi,nodefs.inodesFree\<5%”, “–image-gc-high-threshold=100%”, “–image-gc-low-threshold=100%”]’

[worker]  
9.42.23.147

[proxy]  
9.42.23.241 kubelet\_extra\_args=‘[“–eviction-hard=memory.available\<100Mi,nodefs.available\<2Gi,nodefs.inodesFree\<5%”, “–image-gc-high-threshold=100%”, “–image-gc-low-threshold=100%”]’

[management]  
9.42.23.241 kubelet\_extra\_args=‘[“–eviction-hard=memory.available\<100Mi,nodefs.available\<2Gi,nodefs.inodesFree\<5%”, “–image-gc-high-threshold=100%”, “–image-gc-low-threshold=100%”]’

This runs fine on Ubuntu, but when I run on RHEL, I get:

to retry, use: --limit @/root/ansible/deploy.retry

groups.worker and groups.proxy is just those literal strings, not the IP addresses specified in the inventory file. Thoughts on what is wrong?
