Under the original code, leader election failed for ingress controllers as a result of mismatch between election-id in the controller config, and the resourceName in the relevant rule of role 'ingress-nginx'. This appeared in the controller logs. To fix the issue, a command-line option was added to container execution (--election-id=...). Now, the election-id agrees with the resourceName provided in the role-ingress-nginx.yml file. A comment in that file was changed to reflect the new logic.
