How to configure S3
An S3 bucket can be leveraged to serve the static content uploaded to Indico, potentially improving performance. Moreover, it is required when scaling the charm to serve the uploaded files. To configure it to set the appropriate connection parameters in s3_storage for your existing bucket juju config [charm_name] s3_storage=[value].
The configuration option s3_storage accepts a comma separated list of parameters as in ‘s3:bucket=my-indico-test-bucket,access_key=12345,secret_key=topsecret’. More details can be found in Indico’s storage S3 documentation.
For more details on the configuration options and their default values see the configuration reference.
