k8s: Updating a Secret

Hopefully helped another k8s newbie with the following. The question was, how do you update a single key in a secret in k8s? I don't know anything about secrets but I will probably want to know this in the future, so here we go.

First, to create a dummy secret:

apiVersion: v1

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

write utf-16 encoded files in node.js (both utf16be and utf16le)
const fs = require('fs');
// our demo string is in 'default' utf8 with emoji character assuming you are using an editor that supports those.
// if not, you can test this gist by setting utf8string to the equivalent '->\ud83d\ude03\ud83e\uddd2\ud83c\udffc\u00fc\u010d\u0113<-'
// gist doesn't support all ZWJ sequences, so can't show this here but it works with those as well, e.g. '\ud83d\udc68\ud83c\udffc\u200d\ud83d\udcbb'
const utf8string = '->😃🧒🏼üčē<-';
// this is what you'd usually do to write to a utf-8 encoded file
fs.writeFileSync('test-utf8.txt', utf8string);
