Configure S3 for RadosGW
A Charmed PostgreSQL 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 PostgreSQL application, and update it. (To configure S3 for AWS, see this guide)
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="/postgresql" \
region="" \
s3-api-version="" \
s3-uri-style="path" \
tls-ca-chain="$(base64 -w0 /path-to-your-server-ca-file)"
Integrate with Charmed PostgreSQL
To pass these configurations to Charmed PostgreSQL, integrate the two applications:
juju integrate s3-integrator postgresql
You can create, list, and restore backups now:
juju run postgresql/leader list-backups
juju run postgresql/leader create-backup
juju run postgresql/leader list-backups
juju run postgresql/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.
