How can I mount a docker config file with Skaffold?

I want to use the Prometheus image to deploy a container as part of the local deployment. Usually one has to run the container with volume and bind-mount to get the configuration file (prometheus.yml) into the container:

docker run \
    -p 9090:9090 \
    -v /path/to/prometheus.yml:/etc/prometheus/prometheus.yml \
    prom/prometheus

How can I achieve this with Kubernetes when using Skaffold?

Your Kubernetes configuration will be something like this, You can specify the port number and volume mounts. The important sections for mounting are volumeMounts and volumes.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-prom
spec:
  selector:
    matchLabels:
      app: my-prom
  template:
    metadata:
      labels:
        app: my-prom
    spec:
      containers:
      - name: my-prom
        image: prometheus:latest
        resources:
          limits:
            memory: "128Mi"
            cpu: "500m"
        ports:
        - containerPort: 9090
        volumeMounts:
          - name: prom-config
            mountPath: /path/to/prometheus.yml
      volumes:
        - name: prom-config
          hostPath:
              path: /etc/prometheus/prometheus.yml
---
apiVersion: v1
kind: Service
metadata:
  name: my-prom
spec:
  selector:
    app: my-prom
  ports:
  - port: 9090
    targetPort: 9090

save the Kubernetes config file in a folder and add below config to skaffold.yaml with the path to K8s config file,

deploy:
  kubectl:
    manifests:
    - k8s/*.yaml
