Configuring S3-storage requires that you have a replica set with at least three-nodes deployed and access to S3 storage. If you don’t have a three node replica set read the Managing Units How-To for VM charm.
Once you have a three-node replica set deployed, you can configure your settings for S3. Configurations are managed with the s3-integrator charm. Deploy and configure the s3-integrator charm:
juju deploy s3-integrator juju run s3-integrator/leader sync-s3-credentials access-key=<access-key-here> secret-key=<secret-key-here> juju config s3-integrator \ path="mongodb-vm/demo" \ region="us-west-2" \ bucket="pbm-test-bucket-1"
The s3-integrator charm accepts many configurations - enter whatever configurations are necessary for your s3 storage.
To pass these configurations to Charmed MongoDB, relate the two applications:
juju integrate s3-integrator mongodb
You can also update your configuration options after relating:
juju config s3-integrator \ endpoint=<endpoint>
