gordon-config v0.0.1

Gordon-config

Warn: Work in progress

This tools aim to use with gordon which is a excellent lambda deployment tool on AWS platform. Gordon-config help us to configure gordon settings and parameter by calling other cloud formation stack.

Why this tool:

• We have several AWS account to manage
• Each account have custom configuration for the same application code
• We have several lambda runtime to manage (python, nodejs)
• We using a lot cloud formation

We started to wrote using nodejs for quickly obtain a prototype. We have in mind to:

• rewrite with python very soon.
• share this work to gordon project

Command line tool

For help

gordon-config -h

usage: gordon-config [-h] [-v] [-s STACK_NAME] [-n NAME] [-p PROFILE]
                     [-r REGION] [-t TEMPLATE]
                     output

Gordon configuration utility.

Positional arguments:
  output                Directory where to write output.

Optional arguments:
  -h, --help            Show this help message and exit.
  -v, --version         Show program's version number and exit.
  -s STACK_NAME, --stack-name STACK_NAME
                        Cloudformation stack name.
  -n NAME, --name NAME  Stage name.
  -p PROFILE, --profile PROFILE
                        Optional AWS profile name.
  -r REGION, --region REGION
                        Optional AWS region name.
  -t TEMPLATE, --template TEMPLATE
                        Optional settings template file.

Main Usage: Add cloudformation stack output as parameters

We start by using:

• a "settings.yml" as template,
• a cloud formation stack name
• an output target directory
• a stage name
• optional AWS configuration parameter (region, or named profile ). Use standard AWS environment variable to configure AWS access.

First, install gordon-config:

npm install gordon-config

Run tool

node ./node_module/bin/gordon-config -s mystack -name 'dev' .

Main process is:

• describe cloud formation stack named 'mystack'
• Transform all output parameters as parameters for gordon
• write stage yaml parameters file as 'dev'
• write settings yaml file

After running, the tools write:

• ./settings.yml
• ./parameters/{{stage}}.yml (in our example: ./parameters/dev.yml )

After this process you can using gordon as usual:

gordon build
gordon apply -s {{stage}}
# in our example: gordon apply -s dev

Customize parameters and settings

Customize parameters to put:

• external parameters which define your stack (customer, stage, ...)
• build VPC subnet list
• aggregate another cloud formation stack parameter

Customize settings to put lambda trigger dynamically (based on parameters for example)
