Vault CLI in Containers

In many CI/CD workflows interfacing with Hashicorp Vault is required.

However, their CLI (or better called unified binary¹) is stupidly big with more than 400MB and they seem to have no interest in making it any smaller².

This is often a undesired size increase, especially when optimizing for pull and run time in CI/CD.

This note outlines a solution that brings us down from 400MB+ on disk for vault to about 300KB using curl and jq.

yamllint: Ignore exisiting errors

When adding yamllint to an existing project it can be hard to fix all the errors at once.

I wrote a simple script to create a rules block that simply ignores all rules that currently trigger for a file. This works by generating a rules block ignoring paths.
