amazon web services - CloudFormation S3 specify physical name -


i deployed template s3 bucket. noticed 'logical id' field resource name, 'physical id' field in format of --. there way override behavior? need able specify exact name. everywhere ive looked suggests make through console, that's useless me. need automation.

can me?

i have been coming against same issue. know is possible set physical name of resource when create using ruby sdk aws. use ability can tear down/create elbs known , stable physical names, based on environment , server role, , backend nodes can auto-join upon deployment looking elb corresponding own environment , role.

however, when using cloudformation, resources (elbs, sgs) take resource name specify , prefix or suffix things stackid etc. breaks above system having elb names different after each deployment.

the cloudformation documentation no means bad, seem lack lot of edge cases. haven't yet found out if setting physical name possible or not.

the aws sdk ruby easy use - have no prior experience of ruby - have found straightforward deploy/destroy resources, may find acceptable solution issue if have not had cloudformation joy but, me, require automated route. in fact can use ruby sdk trigger cloudformation stack items names can control, , create others under ruby sdk.
