awsparams

Note

Version 1 of this library is drastically different than previous versions. The CLI Application hasn't changed but the library it uses has. Please pay extra attention to the examples below or look at the underlying class for more information.

Why this script?

The current (Jul 2017) AWS Console for the Systems Manager Parameter Store is good for adding and editing the values of parameters, but misses key productivity functions like copying (especially en mass), renaming, etc. The current aws ssm CLI is very similar in functionality to the AWS Console.

This script is to automate a lot of the manual work currently needed with the existing AWS-provided UIs.

Installation

• AWSParams requires Python 3.6+
• Depending on your Python3.6 install either pip install awsparams or pip3 install awsparams
  • If you're on windows, make sure that C:\Users\{your user}\AppData\Roaming\Python\{your python version}\Scripts has been added to your user path.

Usage

Library:

from awsparams import AWSParams
 
# Using default Profile
aws_params = AWSParams()

# Using a Custome Profile
aws_params = AWSParams('MyProfile')

#get a single parameter
param = get_parameter('test1')
# ParamResult(Name='test1', Value='test123', Type='SecureString')

#ParamResult is a named tuple with properties Name, Value, Type
param.Name # 'test1'
param.Value # 'test123'
param.Type # 'SecureString'

# get multiple parameters with a prefix
params = get_all_parameters(prefix="testing.testing.")
# [ParamResult(Name='testing', Value='1234', Type='String'),
#  ParamResult(Name='testing2', Value='1234', Type='String')]

# get multiple parameters by path
params = get_all_parameters(prefix="/testing/testing/", by_path=True)
# [ParamResult(Name='testing', Value='1234', Type='String'),
#  ParamResult(Name='testing2', Value='1234', Type='String')]

# get multiple parameters by path
params = get_all_parameters(prefix="/testing/testing/", by_path=True, trim_name=False)
# [ParamResult(Name='/testing/testing/testing', Value='1234', Type='String'),
#  ParamResult(Name='/testing/testing/testing2', Value='1234', Type='String')]

# get just a parameter value
value = get_parameter_value('test1')
# test123

Usage: awsparams [OPTIONS] COMMAND [ARGS]...

Options:
--version  Show the version and exit.
--help     Show this message and exit.

Commands:
cp   Copy a parameter, optionally across accounts
ls   List Paramters, optional matching a specific...
mv   Move or rename a parameter
new  Create a new parameter
rm   Remove/Delete a parameter
set  Edit an existing parameter

Command Examples

ls usage

ls names only: awsparams ls

ls with values no decryption: awsparams ls --values or awsparams ls -v

ls with values and decryption: awsparams ls --with-decryption

ls by prefix: awsparams ls appname.prd

ls with values, formatted for using in a Jetbrains run configuration: awsparams ls -r <prefix> or awsparams ls --jetbrains-run-config <prefix>

ls with values, formatted for using in a .env file: awsparams ls -e <prefix> or awsparams ls --dot-env <prefix>

ls with values, formatted for using in a .tfvars file: awsparams ls -t <prefix> or awsparams ls --tfvars <prefix>

For the above two options, add the -q or --esc-quotes flag for adding \ in front of any quotation marks in the values, such as in stringify-ed JSON objects. Most .env file parsers don't require this, but .tfvars probably does.

Add the --delimiter <delimiter> (or -d <delimiter>) option to override the default delimiter (/), if necessary.

new usage

new interactively: awsparams new

new semi-interactively: awsparams new --name appname.prd.username

new non-interactive: awsparams new --name appname.prd.usrname --value parameter_value --description parameter_descripton

cp usage

copy a parameter: awsparams cp appname.prd.username newappname.prd.username

copy set of parameters with prefix appname.dev. to appname.prd.: awsparams cp appname.dev. appname.prd. --prefix

copy set of parameters starting with prefix repometa-generator.prd overwrite existing parameters accross different accounts: awsparams cp repometa-generator.prd --src_profile=dev --dst_profile=trn --prefix=True

copy single parameters accross different accounts: awsparams cp appname.dev.username appname.trb.us

Contributing

To contribute:

• Make a PR to master
  • In your changes, make sure to manually bump the package version in the pyproject.toml file to whatever version you think is appropriate.
• Once the PR is approved, merge it in to master.
• Create a new release and a new tag where the version in the tag is equal to the new version you set in the pyproject.toml file.
• Once you publish the release, check the GitHub actions and notice that it is automatically deploying the package.
• Confirm that the deploy succeeds.
  • If anything goes wrong, fix it and then re-run the workflow.
  • You may have to delete your release/tag and recreate it.
