envoy-job-curl

Small docker image wired with monzo/envoy-preflight and curl that are really usefull when running Kubernetes Jobs/CronJobs inside an Istio service mesh (or similar that injects envoy sidecars for jobs).

Envoy-preflight will handle terminating the envoy sidecar when the main container finishes.
