Deployment API backed by helm charts and tiller
View alecton.proto
// API for a deployment service.
// It's easier for me to express an API as protobuf/service
// definitions. grpc-gateway would be used, so HTTP/1.1 and
// json would work. A simple browser API could be provided.
// This API is meant for users - both systems and humans -
// to easily deploy images.
//
// The envisioned flow is that the build system would push
// images to a registry and notify this service using CreateImage.
// Another step in the pipeline would then use DeployApplication

prometheus - scrape multiple containers in a pod
View gist:5bf7d4e719f36c1c555d81134d8887eb
# Example scrape config for pods
#
# The relabeling allows the actual pod scrape endpoint to be configured via the
# following annotations:
#
# * `prometheus.io/scrape`: Only scrape pods that have a value of `true`
# * `prometheus.io/path`: If the metrics path is not `/metrics` override this. This
# will be the same for every container in the pod that is scraped.
# * this will scrape every container in a pod with `prometheus.io/scrape` set to true and the
port is name `metrics` in the container
