Batch Key Rotation

Note

Added: MinIO

RELEASE.2023-04-07T05-28-58Z

The MinIO Batch Framework allows you to create, manage, monitor, and execute jobs using a YAML-formatted job definition file (a “batch file”). The batch jobs run directly on the MinIO deployment to take advantage of the server-side processing power without constraints of the local machine where you run the MinIO Client.

The keyrotate batch job type cycles the sse-s3 or sse-kms keys for encrypted objects on a MinIO deployment.

The YAML configuration supports filters to restrict key rotation to a specific set of objects by creation date, tags, metadata, or kms key. You can also define retry attempts or set a notification endpoint and token.

Note

Added: MinIO

RELEASE.2023-04-07T05-28-58Z

Use the keyrotate job type to create a batch job that cycles the sse-s3 or sse-kms keys for encrypted objects.

Required Fields

type:

Either sse-s3 or sse-kms.

key:

Only for use with the sse-kms type. The key to use to unseal the key vault.

Optional Fields

For flag based filters

`newerThan:`	A string representing a length of time in `#d#h#s` format. Keys rotate only for objects newer than the specified length of time. For example, `7d`, `24h`, `5d12h30s` are valid strings.
`olderThan:`	A string representing a length of time in `#d#h#s` format. Keys rotate only for objects older than the specified length of time.
`createdAfter:`	A date in `YYYY-MM-DDTHH:MM:SSZ` RFC3339 date and time format. Keys rotate only for objects created after the date.
`createdBefore:`	A date in `YYYY-MM-DDTHH:MM:SSZ` RFC3339 date and time format. Keys rotate only for objects created prior to the date.
`context:`	Only for use with the `sse-kms` type. The context within which to perform actions.
`tags:`	Rotate keys only for objects with tags that match the specified `key:` and `value:`.
`metadata:`	Rotate keys only for objects with metadata that match the specified `key:` and `value:`.
`kmskey:`	Rotate keys only for objects with a KMS key-id that match the specified value. This is only applicable for the `sse-kms` type.

For notifications

`endpoint:`	The predefined endpoint to send events for notifications.
`token:`	An optional JSON Web Token (JWT) to access the `endpoint`.

For retry attempts

If something interrupts the job, you can define a maximum number of retry attempts. For each retry, you can also define how long to wait between attempts.

`attempts:`	Number of tries to complete the batch job before giving up.
`delay:`	The amount of time to wait between each attempt.

Sample YAML Description File for a `keyrotate` Job Type

Use mc batch generate to create a basic keyrotate batch job for further customization:

keyrotate:
  apiVersion: v1
  bucket: BUCKET
  prefix: PREFIX
  encryption:
    type: sse-s3 # valid values are sse-s3 and sse-kms
    key: <new-kms-key> # valid only for sse-kms
    context: <new-kms-key-context> # valid only for sse-kms

  # optional flags based filtering criteria
  # for all objects
  flags:
    filter:
      newerThan: "7d" # match objects newer than this value (e.g. 7d10h31s)
      olderThan: "7d" # match objects older than this value (e.g. 7d10h31s)
      createdAfter: "date" # match objects created after this date and time in RFC3339 format
      createdBefore: "date" # match objects created before this date and time in RFC3339 format
      tags:
        - key: "name"
          value: "pick*" # match objects with tag 'name', with all values starting with 'pick'
      metadata:
        - key: "content-type"
          value: "image/*" # match objects with 'content-type', with all values starting with 'image/'
      kmskey: "key-id" # match objects with KMS key-id (applicable only for sse-kms)
    notify:
      endpoint: "https://notify.endpoint" # notification endpoint to receive job status events
      token: "Bearer xxxxx" # optional authentication token for the notification endpoint
    retry:
      attempts: 10 # number of retries for the job before giving up
      delay: "500ms" # least amount of delay between each retry

`type:`	Either `sse-s3` or `sse-kms`.
