Kubernetes

The Kubernetes example runs the Docker image as a pod or a CronJob, with its settings in a ConfigMap and a hardened security context.

File	Holds
`configmap.yaml`	The settings file, as the `speedtest-settings` ConfigMap
`pod.yaml`	A pod that runs one speed test
`cronjob.yaml`	A CronJob that runs a speed test every six hours

Run it

Create the settings:

kubectl apply -f https://raw.githubusercontent.com/nicholas-fedor/speedtest-go/master/example/kubernetes/configmap.yaml

Run a speed test once, and read its JSON results once the pod has finished:

kubectl apply -f https://raw.githubusercontent.com/nicholas-fedor/speedtest-go/master/example/kubernetes/pod.yaml
kubectl wait --for=jsonpath='{.status.phase}'=Succeeded pod/speedtest --timeout=3m
kubectl logs speedtest

Or run speed tests on a schedule:

kubectl apply -f https://raw.githubusercontent.com/nicholas-fedor/speedtest-go/master/example/kubernetes/cronjob.yaml

To try the CronJob without waiting for its schedule, start a job from it:

kubectl create job speedtest-now --from=cronjob/speedtest

Settings

To	Do
Change the defaults	Edit the ConfigMap and apply it again. The next run reads the new settings
Override a setting with a flag	Add it to the container’s `args`, such as `args: ["--server", "6691"]`
Override a setting with a variable	Add it to the container’s `env`, such as `SPEEDTEST_GO_SERVER` with the value `6691,6087`

Flags go in args, since the image’s entrypoint is speedtest-go. ICMP pings do not work in the image, so use --ping-mode http or tcp.
