Spread Scheduling

Overview

Nova supports spreading a group of workloads onto multiple clusters. This means that the whole group can be cloned and run in the multiple workload clusters. User also has a control over spread constraints, e.g.: user can specify that 70% of replicas of given workload has to run in any cluster from group A, and the rest in any cluster in group B. This may be useful in cases such us spreading a workload across clusters in different zones / regions to ensure High Availability.

User can also use Spread scheduling to ensure that all clusters (or subset of clusters) is running a group of workloads, e.g. to ensure that each cluster has cert-manager running with the same configuration.

Tutorial

In this example, we will group nginx Deployment and ServiceAccount onto two workload clusters and we will learn how to configure spread constraints in SchedulePolicy. To follow this tutorial you will need Nova Control Plane with at least two workload clusters connected. You can check connected clusters using kubectl:

$ kubectl get clusters --show-labels
NAME K8S-VERSION K8S-CLUSTER REGION ZONE READY IDLE STANDBY LABELS
kind-workload-1 1.22 workload-1 True True False kubernetes.io/metadata.name=kind-workload-1,nova.elotl.co/cluster.novacreated=false,nova.elotl.co/cluster.provider=kind,nova.elotl.co/cluster.version=1.22
kind-workload-2 1.22 workload-2 True True False kubernetes.io/metadata.name=kind-workload-2,nova.elotl.co/cluster.novacreated=false,nova.elotl.co/cluster.provider=kind,nova.elotl.co/cluster.version=1.22

Here is ServiceAccount & Deployment we want to spread:

    $ cat <<EOF > sample-spread-scheduling/nginx-app.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx
namespace: default
labels:
app: nginx
group-policy: nginx-spread
spec:
replicas: 10
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
group-policy: nginx-spread
spec:
serviceAccountName: nginx-sa
containers:
- name: nginx
image: nginx:1.14.2
ports:
- containerPort: 80
---
apiVersion: v1
kind: ServiceAccount
metadata:
name: nginx-sa
namespace: default
labels:
app: nginx
group-policy: nginx-spread
EOF

Now, we need to define SchedulePolicy matching those two objects. We want to run 50% of replicas in kind-workload-1 cluster and 50% in kind-workload-2. ServiceAccount needs to be present in both clusters.

    $ cat <<EOF > sample-spread-scheduling/policy.yaml
apiVersion: policy.elotl.co/v1alpha1
kind: SchedulePolicy
metadata:
name: spread-group-policy
spec:
namespaceSelector:
matchLabels:
kubernetes.io/metadata.name: default
groupBy:
labelKey: app
spreadConstraints:
topologyKey: kubernetes.io/metadata.name
clusterSelector:
matchExpressions:
- key: kubernetes.io/metadata.name
operator: In
values:
- kind-workload-1
- kind-workload-2
resourceSelectors:
labelSelectors:
- matchLabels:
group-policy: nginx-spread
EOF

Let's explain each field in .spec:

  • namespaceSelector says "Match only k8s resources (e.g. Deployment) in default namespace"
  • groupBy says "For each matched object, check a value of label app. Create ScheduleGroup containing k8s resources that share the same value of this label"
  • spreadConstraints says "For each matched cluster, check a value of kubernetes.io/metadata.name and create a bucket of clusters for every value of that label" (In this example, we use label which value is unique for each cluster, so every bucket will have only one cluster)
  • clusterSelector says "Consider workload clusters which have kubernetes.io/metadata.name equal to kind-workload-1 or kind-workload-2"
  • resourceSelectors says "Match only k8s resources (e.g. Deployment) that have label group-policy=nginx-spread"

Note: If your workload clusters have different names, you need to edit this policy before applying.

We can now apply policy and nginx app to the Nova Control Plane:

$ kubectl apply -f sample-spread-scheduling/policy.yaml
$ kubectl apply -f sample-spread-scheduling/nginx-app.yaml

Nova should now create nginx Deployment with 5 replicas in kind-workload-1 & kind-workload-2. Nova will sync Deployment status to the Control Plane:

$ kubectl --context=nova get deployment,serviceaccount
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/nginx 10/10 10 10 51s

NAME SECRETS AGE
serviceaccount/nginx-sa 1 51s

Currently, Nova supports syncing status for Deployments, ReplicaSets and StatefulSets.

Let's verify if 5 replicas run in both clusters:

$ kubectl --context=kind-workload-1 get deployment,serviceaccount
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/nginx 5/5 5 5 2m25s

NAME SECRETS AGE
serviceaccount/default 1 18h
serviceaccount/nginx-sa 1 2m25s

$ kubectl --context=kind-workload-2 get deployment,serviceaccount
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/nginx 5/5 5 5 2m25s

NAME SECRETS AGE
serviceaccount/default 1 18h
serviceaccount/nginx-sa 1 2m25s

Define % split of replicas

Nova also provides a way to define not even split of replicas between workload clusters. For that purpose, you need to specify this constraint in SchedulePolicy's .spec.spreadConstraints.

    $ cat <<EOF > sample-spread-scheduling/policy-percentage.yaml
apiVersion: policy.elotl.co/v1alpha1
kind: SchedulePolicy
metadata:
name: spread-group-policy
spec:
namespaceSelector:
matchLabels:
kubernetes.io/metadata.name: default
groupBy:
labelKey: app
spreadConstraints:
topologyKey: kubernetes.io/metadata.name
percentageSplit:
- topologyValue: kind-workload-1
percentage: 20
- topologyValue: kind-workload-2
percentage: 80
clusterSelector:
matchExpressions:
- key: kubernetes.io/metadata.name
operator: In
values:
- kind-workload-1
- kind-workload-2
resourceSelectors:
labelSelectors:
- matchLabels:
group-policy: nginx-spread
EOF

We added percentageSplit field, which says "Run 20% of replicas in a workload cluster with kubernetes.io/metadata.name=kind-workload-1 and 80% in kubernetes.io/metadata.name=kind-workload-2 workload cluster"

We can apply this policy now, and Nova will apply changes to match the constraints we specified.

$ kubectl --context=nova apply -f sample-spread-scheduling/policy-percentage.yaml

When you update spreadConstraints in the SchedulePolicy, Nova will always re-balance the split to ensure that your requirements are met.

Let's verify if kind-workload-1 has 2 replicas and kind-workload-2 8 replicas.

$ kubectl --context=kind-workload-1 get deployment,serviceaccount
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/nginx 2/2 2 2 2m25s

NAME SECRETS AGE
serviceaccount/default 1 18h
serviceaccount/nginx-sa 1 2m25s

$ kubectl --context=kind-workload-2 get deployment,serviceaccount
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/nginx 8/8 8 8 2m25s

NAME SECRETS AGE
serviceaccount/default 1 18h
serviceaccount/nginx-sa 1 2m25s

NOTE: For k8s resources which aren't pod controllers (pod controllers such as Deployment, ReplicaSet, StatefulSet, etc.) percentage split is ignored (resource will be created in each cluster). In our tutorial, ServiceAccount represents such resource.

NOTE: Nova will try it's best to satisfy % split. But in cases when it's not possible to divide replicas without the remainder, Nova will floor the result of division (e.g. 5 replicas, 70%/30% split, will result in 3/1 split)

To clean up all resources created in this tutorial, run:

$ kubectl --context=nova delete -f sample-spread-scheduling/nginx-app.yaml
$ kubectl --context=nova delete -f sample-spread-scheduling/policy-percentage.yaml

Tutorial: Spreading the same workloads in the all clusters equally

In this tutorial, we will configure SchedulePolicy for spreading a group of workloads across multiple clusters, without defining any additional spreadConstraints. Our goal is to have cert-manager controllers running in every cluster that we specify in SchedulingPolicy. We will also see how the cert-manager deployment status is synced into one from multiple workload clusters.

Prerequisites:

  • Nova control plane deployed with two workload clusters connected (You can follow installation guide if you don't have it.)

We will use official cert-manager manifests in version v1.11.0 with a few modifications:

  • we are going to add label to the cert-manager namespace, so it can be scheduled alongside everything else as one group
  • we will move Roles and RoleBindings from kube-system to cert-manager (because objects in kube-system namespace are skipped in Nova by default)
  • IMPORTANT we will bump number of replicas of cert-manager-cainjector, cert-manager and cert-manager-webhook from 1 to 2, because we will target 2 workload clusters (1 replica each)
