I have tried to create and deploy on Elastic Beanstalk. It never works. I have spent over 14 hours trying to get EB to work over the course of 1 month. I have followed online tutorials in addition to the tutorials in AWS documentation, both for "real" deployments and the simple example deployments. I have never successfully gotten anything to work with Elastic Beanstalk.
The most recent error, trying to create the simplest possible example deployment, is this:
October 15, 2023 22:07:57 (UTC-5) ERROR LaunchWaitCondition failed. The expected number of EC2 instances were not initialized within the given time. Rebuild the environment. If this persists, contact support. October 15, 2023 22:07:56 (UTC-5) ERROR Stack named 'awseb-e-[...]-stack' aborted operation. Current state: 'CREATE_FAILED' Reason: The following resource(s) failed to create: [AWSEBInstanceLaunchWaitCondition].
