Important Factoids

ElasticBeanstalk's resource has a number of "bugs" and "issues", and we've had to work around quite a few of them. Name being modified on every apply (well, which fails), etc.

EDIT: Added code block to relevant resource. Assumed it would automatically by the form.

References

19679 is also happening. There I removed the cname_prefix attribute and was expecting a re-creation/replacement of the resource, or at least a modification of the resource.

Would you like to implement a fix?

None
