Blow up your cloud-init developer workflows!

See the examples dir for examples running on your local machine or deploying to cloud providers.

npm i -g @eighty4/c2
c2 -h

c2 ./cloud_init_dir

# base64 encode your user data
c2 --base64 ./cloud_init_dir

import { buildUserData } from '@eighty4/c2'

const userData: string = await buildUserData('./cloud_init_dir')

Multiple user data are ordered by filenames and 01_ numbered prefixes help declare execution order.

ls ./cloud_init_dir
01_upgrades.yml
02_security.yml
03_services.sh

Shell scripts are supported as x-shellscript and YAML is included as cloud-config MIME types.

Scripts and YAML support two template functions that can be used in expressions.

Replaces expression with content of a local environment variable.

#!/bin/sh

ENV_VAR="${{ env('LOCAL_ENV_VAR') }}"

Looks up a file from your local filesystem and replaces the expression with its content.

#cloud-config

users:
    - name: devops-baller
      ssh_authorized_keys:
          - ${{ file('~/.ssh/my_ssh_key.pub') }}

Relative, absolute and ~/ paths are supported.

I use c2 for initializing Debian cloud instances and locally test with QEMU and Ubuntu.

Feedback on your use cases and worfklows is greatly appreciated!
