Dask Cluster

Running a dask cluster in your namespace

Create a dask cluster according to https://kubernetes.dask.org/en/latest/operator_resources.html, for example:

apiVersion: kubernetes.dask.org/v1
kind: DaskCluster
metadata:
  name: my-dask-cluster
spec:
  worker:
    replicas: 2
    spec:
      containers:
      - name: worker
        image: "ghcr.io/dask/dask:latest"
        imagePullPolicy: "Always"
        args:
          - dask
          - worker
          - --name
          - $(DASK_WORKER_NAME)
          - --dashboard
          - --dashboard-address
          - "8788"
        ports:
          - name: http-dashboard
            containerPort: 8788
            protocol: TCP
        resources:
          limits:
            cpu: "2"
            memory: 5Gi
          requests:
            cpu: 100m
            memory: 512Mi
  scheduler:
    spec:
      containers:
      - name: scheduler
        image: "ghcr.io/dask/dask:latest"
        imagePullPolicy: "Always"

            containerPort: 8786
            protocol: TCP
          - name: http-dashboard
            containerPort: 8787
            protocol: TCP
        readinessProbe:
          httpGet:
            port: http-dashboard
            path: /health
          initialDelaySeconds: 5
          periodSeconds: 10
        livenessProbe:
          httpGet:
            port: http-dashboard
            path: /health
          initialDelaySeconds: 15
          periodSeconds: 20
        resources:
          limits:
            cpu: "2"
            memory: 5Gi
          requests:
            cpu: 100m
            memory: 512Mi
    service:
      type: ClusterIP
      selector:
        dask.org/cluster-name: my-dask-cluster
        dask.org/component: scheduler
      ports:
      - name: tcp-comm
        protocol: TCP
        port: 8786
        targetPort: "tcp-comm"
      - name: http-dashboard
        protocol: TCP
        port: 8787
        targetPort: "http-dashboard"
