Currently the default timeout of 1 second and no initial delay is applied to the probes of the runner pods. Depending on the startup time this can cause random Pod errors causing a whole TestRun to fail.

At some point it might also make sense to introduce a startupProbe to cover the longer initial startup time a K6 instance (Pod) might need instead of every increasing the runtime liveness and readiness checks.

Fixes #306

…delay

Currently the default timeout of 1 second and no initial delay is applied
to the probes of the runner pods. Depending on the startup time this
can cause random Pod errors causing a whole TestRun to fail.

At some point it might also make sense to introduce a startupProbe to cover
the longer initial startup time a K6 instance / pod might need instead of ever
increasing the runtime liveness and readiness checks.

Since having the Liveness and Readiness checks be just the same makes not much
sense, as the liveness check fail will cause the container to be restarted,
this change also splits up those two tests, to allow for more individual
configuration, be it timers or what is actually checked.

Fixes grafana#306

@yorugac Since you opened the issue (#306) PTAL at this proposed fix / mitigation.

As commented, I believe a startup probe would make some sense and also distinguishing between liveness and readiness checks (which have totally different purpose).
