# Configs

Toolset to manage encrypted application configs and vaults. Or something.

## Usage

### Transform

    Usage:
    configs transform [options] <input> <format> <output>

Render a config file into a target format.

 * `input`: input file name, or `-` to use stdin
 * `format`: format to render
 * `output`: output file name, or `-` to use stdout

Options:

 * `-v`, `--vault`: specify a vault for resolving secrets; can be specified
   multiple times to allow for adding fallbacks

### Provision

    Usage:
    configs provision <input> <source-vault> <target-vault>

Resolve all secrets using one vault, and store them all in a target vault.

 * `input`: input file name, or `-` to use stdin
 * `source-vault`: vault to use to resolve all secrets
 * `target-vault`: vault to store all secrets in


## Supported Formats

### env

    env:
      fields:
        <field-name>: <config-path>
        <field-name>: <config-path>

Fetch values from the config or vaults and output them into a flat list of
key-value variables surrounded by double quotes. No effort is made to escape
the values right now.


## Supported Vaults

### sops

    sops:

Use mozilla's sops command line tool to decrypt the input config. Further config
should be done using the sops tool itself.

Encrypting a new file with a local pgp key:

    sops --encrypted-suffix _encrypted -i --pgp ABCD1234ABCD1234ABCD1234 --encrypt myfile.yaml

Encrypting a new file with AWS:

	sops --encrypted-suffix _encrypted -i --kms arn:aws:kms:us-west-2:123412341234:key/11111111-2222-3333-4444-555555555555 --encrypt myfile.yaml

### aws

    aws:
      base_path: base/path/name/

Fetch values from Amazon's Secret Manager service.

Values with the same prefix will be combined into values on a single secret.

E.g., with:

 * `database.connection.username` and
 * `database.connection.password`

A single secret will be created at `database/connection` with the `username` and
`password` properties.

Optionally, specify a base path that will be prepended to all secret names.


## Example Configuration

    # Required -- currently only version 0 is supported
    meta:
        version: 0

    # Unencrypted configuration values.
    # You can use any arbitrary structure here.
    config:

                host: rds.url.amazonaws.com
                name: testdatabase
                asdf:
                    test: 1

    # Encrypted configuration values for sops.
    # Edit these by running `sops my-config.yaml`.
