Go Templates

template expressions use the Go Text Template library with some additional functions provided by the gomplate library. In this example we get the current exchange rate:

display-with-gotemplate.yaml

apiVersion: canaries.flanksource.com/v1
kind: Canary
metadata:
  name: http-check
spec:
  http:
    - name: USD
      url: https://api.frankfurter.app/latest?from=USD&to=GBP,EUR,ILS,ZAR
      display:
        template: "$1 = €{{.json.rates.EUR}}, £{{.json.rates.GBP}}, ₪{{.json.rates.ILS}}"
