You had ONE JOB -- A Kubernetes job.

You had ONE JOB -- A Kubernetes job.

Let's take a look at how Kubernetes jobs are crafted. I had been jamming some kind of work-around shell scripts in the entrypoint* for some containers in the vnf-asterisk project that Leif and I have been working on. And that's not perfect when we can use Kubernetes jobs, or in their new parlance, "run to completion finite workloads" (I'll stick to calling them "jobs"). They're one-shot containers that do one thing, and then end (sort of like a "oneshot" of systemd units, at least how we'll use them today). I like the idea of using them to complete some service discovery for me when other pods are coming up. Today we'll fire up a pod, and spin up a job to discover that pod (by querying the API for info about it), and put info into etcd. Let's get the job done.

Create a service account and generate a kubeconfig file for it - this will also set the default namespace for the user
#!/bin/bash
set -e
set -o pipefail
# Add user to k8s using service account, no RBAC (must create RBAC after this script)
if [[ -z "$1" ]] || [[ -z "$2" ]]; then
echo "usage: $0 <service_account_name> <namespace>"
exit 1

Falsehoods programmers believe about time, in a single list

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

  • There are always 24 hours in a day.
  • February is always 28 days long.
  • Any 24-hour period will always begin and end in the same day (or week, or month).
