I am facing an issue where I need to specify hosts like this
1. - hosts: "swarm-init-{{ env }}"
but trying to use that group value in hostvars stanza yields the below
error. any suggestions?
1. mtoken: "{{ hostvars[groups['swarm-init-{{ env }}'][0]]['manager'] |
replace('[u', '') | replace(']', '')}}"
{"failed": true, "msg": "'dict object' has no attribute 'swarm-init-{{ env
}}'"}
