How do I flush the cache in Elastic Beanstalk?

Question

I'm using the command line to create an environment using the following command:

eb create staging -i t2.small

I then get the following error message:

2018-07-31 20:13:16    ERROR   Each option setting in configuration file .ebextensions/options.config in application version app-c8f2-180731_201302 must be a map. Update each option setting in the configuration file.

When I delete the options.config and run the command again, I get exactly the same error. More fully:

2018-07-31 20:17:04    INFO    createEnvironment is starting.
2018-07-31 20:17:05    INFO    Using elasticbeanstalk-us-east-1-413395812799 as Amazon S3 storage bucket for environment data.
2018-07-31 20:17:06    ERROR   Each option setting in configuration file .ebextensions/options.config in application version app-c8f2-180731_201651 must be a map. Update each option setting in the configuration file.
2018-07-31 20:17:07    ERROR   Failed to launch environment.

ERROR: ServiceError - Failed to launch environment.

It therefore seems that Elastic Beanstalk is caching an old version of the program.

If so, how do I flush the cache?

If not, why do I still get the error even after I delete the file?

Answer 1

You are deleting the file and running create again on an environment that has already been initialized.

Try running eb deploy to push new changes to your already initialized Elastic Beanstalk environment instead.
