ebcli.objects.exceptions.ServiceError: Failed to deploy application.
This error appears when I deploy my application to eb (eb deploy). How do I deploy this successfully?

Answer 1

It looks like your application failed to deploy onto the EC2 instance. You should be able to get a detailed log of what went wrong by downloading the logs and checking them.
You can get the logs with the EB CLI like so:
eb logs --all
The log file that will have the deployment logs will be the /var/log/eb-activity.log which you can find here after running the above command:
/PROJECT-ROOT/.elasticbeanstalk/logs/latest/i-xxxxxxx/var/log/eb-activity.log
The error logs of why your instance failed to delete should be in this log file.
