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.
