go-k8s-b64

A very simple wrapper to base64 encode strings.

Why

I use envsubst for injecting Kubernetes secrets when kubectl applying.

echo adds a newline by default and I always forget the -n argument, which ends up breaking secrets. This tool does not add a newline.

Build the project:

go build -o b64 .

Place the binary in your PATH:

cp b64 ~/bin/b64

Invoke it with one argument, the string to encode:

b64 'foobarSECRE&A'

You can verify the string by piping to base64 -d
