Q: How do I configure my Tower-invoked pipeline to be able to write to an S3 bucket that enforces AES256 server-side encryption?

If you need to save files to an S3 bucket protected by a bucket policy which enforces AES256 server-side encryption, additional configuration settings must be provided to the nf-launcher script which invokes the Nextflow head job:

1. Add the following configuration to the Advanced options > Nextflow config file textbox of the Launch Pipeline screen:

aws {
  client {
    storageEncryption = 'AES256'
  }
}

export TOWER_AWS_SSE=AES256
