Each account in the amazon has a limitation to hold 10 SSL certs and if you exceed this value, you wont be able to upload/attach any more SSL certificates to the load balancers (ELB’S). It will throw an quota exceed error.
You cannot delete amazon SSL certificates through GUI. Amazon API tools is required for this task.
Download the IAMCli utilities from amazon and untar it in /root
List the available SSL certificates in the account
# /root/IAMCli-1.2.0/bin/iam-servercertlistbypath –aws-credential-file /root/my-account-creds.txt
Delete the unwanted certificate using the following command
/root/IAMCli-1.2.0/bin/iam-servercertdel –aws-credential-file my-account-creds.txt -s dsp-olokiran-com-cert
# cat /root/my-account-creds.txt
Using the same tools you can even attach SSL certificates to the ELB’s.
