Upstream industry changes
The following sections refer to recent changes in the Open Source software DKP uses. That may require action on your part as part of an upgrade or installation of D2iQ software.
Docker hub rate limiting
Docker Hub announced an update to their image pull policies in August, 2020. The change results in the need to change cluster configurations to accommodate new account structures that enable image pull rate limiting.
Rate limiting happens on a per-pull basis regardless of whether the pulled image is owned by a paid user. This means D2iQ, as owner of most images used in Konvoy, does not have any influence as to whether your current address is rate-limited or not. Konvoy does not have a strict dependency on Docker Hub accounts or plans.
For more information on addressing this limit, see Docker hub rate limits.
KUDO Spark Operator Upgrade Prior to Konvoy Upgrade or Install
Custom Resource Definitions (CRD) of KUDO Spark Operator versions prior to 3.0.0-1.1.0 do not specify default values for
x-kubernetes-list-map-keys properties and will fail validation on Kubernetes versions 1.18.x and later.
Perform these steps before upgrading or installing Konvoy to prevent or mitigate disruption of currently-running Spark jobs and invalidating Spark CRDs:
- Wait for the KUDO Spark Operator jobs to finish, or terminate the running jobs.
- Uninstall the KUDO Spark Operator.
- Install the new KUDO Spark version.
- Upgrade or install Konvoy.
