Configure S3 for RadosGW

A MySQL backup can be stored on any S3-compatible storage. S3 access and configurations are managed with the s3-integrator charm.

This guide will teach you how to deploy and configure the s3-integrator charm on Ceph via RadosGW, send the configuration to a Charmed MySQL application, and update it.

For AWS, see the guide How to configure S3 for AWS

Configure s3-integrator

First, install the MinIO client and create a bucket:

mc config host add dest https://radosgw.mycompany.fqdn <access-key> <secret-key> --api S3v4 --lookup path
mc mb dest/backups-bucket

Then, deploy and run the charm:

juju deploy s3-integrator
juju run s3-integrator/leader sync-s3-credentials access-key=<access-key> secret-key=<secret-key>

Lastly, use juju config to add your configuration parameters. For example:

juju config s3-integrator \
    endpoint="https://radosgw.mycompany.fqdn" \
    bucket="backups-bucket" \
    path="/mysql" \
    region="" \
    s3-api-version="" \
    s3-uri-style="path"

Integrate with Charmed MySQL

To pass these configurations to Charmed PostgreSQL, integrate the two applications:

juju integrate s3-integrator mysql

You can create, list, and restore backups now:

juju run mysql/leader list-backups
juju run mysql/leader create-backup
juju run mysql/leader list-backups
juju run mysql/leader restore backup-id=<backup-id-here>

You can also update your S3 configuration options after integrating using

juju config s3-integrator <option>=<value>

The s3-integrator charm accepts many configurations - enter whatever configurations are necessary for your S3 storage.
