Utilities for interacting with AWS Parameter Store. aws configure should be run beforehand for proper operation.

Requirements
  • Python 3.5 or above
  • The AWS CLI
  • A successful run of aws configure
fetch_params

Get the names and values of parameters whose names begin with a given prefix. Uses aws ssm describe-parameters and get-parameters, to compile names and values into a convenient format.

For example, passing the prefix foo would fetch parameters named foo.A, foo.B etc. but not bar.foo.

Usage

  • python fetch_params.py foo

    Writes matching parameters to STDOUT.

set_param

Create a parameter or update an existing one. Can also be used with an input file to create / update multiple parameters simultaneously.

Usage

  • python set_param -p foo -v bar

    Creates a parameter named foo with value bar. By default, uses the SecureString parameter type

  • python set_param -p foo -v bar -t String

    Creates a parameter named foo with value bar with type String. Valid types:

    • String
    • StringList
    • SecureString

  • python set_param -p foo -v bang -o

    Overwrite foo's value to bang.

  • python set_param -j parameters.json

    Create or update parameters from the file parameters.json containing parameter data in the format:

    [
   {
     "Name": "foo",
     "Value": "bar"
   },
   {
     "Name": "this",
     "Value": "that"
   }
 ]

    Type and Overwrite keys can also be included for each parameter. If omitted, these options default to SecureString and False.

list_ecs_services

Get the names of available clusters and services.

Usage

  • python list_ecs_services.py

    To print names of all available clusters and services

  • python list_ecs_services.py --arn

    To print full ARNs of all available clusters and services

get_ecs_url

Get the private DNS of an ECS instance for a given cluster and service.

Usage
