Minio SSE (Server Side Encryption)
MinIO SSE uses Key Encryption Service (KES) to secure objects at the storage layer.
We can test this using the KMS server at play.min.io
Keycloak over SSL
If you are using keycloak over SSL you'll need to copy the CA certifcate for keycloak in to the /root/.minio/certs/CAs directory.
This is required so Minio can read the keycloak endpoints over https.
You can create a secret to store and CA and then mount it in the /root/.minio/certs/CAs directoryDownload the root.key and root.cert fom the play.min.io server:
| Code Block | ||||
|---|---|---|---|---|
| ||||
curlkubectl -sSL --tlsv1.2 -O 'https://raw.githubusercontent.com/minio/kes/master/root.key' -O 'https://raw.githubusercontent.com/minio/kes/master/root.cert' |
Use these to create a secret, mount the secret in the pod, then setup some environment variables to enable SSE.
