AWS Parameter Store

Abstract

---

• A central place to store the parameters used by others AWS Services

Cheatsheet

# Update a particular parameter store item
aws ssm put-parameter \
	--name "<parameter_name>"\
	--value "<parameter_value>" \
	--type SecureString \
	--overwrite

Update in bulk Programmatically

---

• One common use case of this service is to add/delete/access/modify the parameters
• Doing these operations programmatically is less error prone & faster

1) Install aws-parameter-bulk

brew tap gork74/gork7
brew install aws-parameter-bulk

2) Carry out the operation

# Grab all the parameters from <YOUR_AWS_PROFILE> from the <YOUR_AWS_REGION>, and save them to your current directory in a file called `.env`
AWS_PROFILE=<YOUR_AWS_PROFILE> \
AWS_REGION=<YOUR_AWS_REGION> \
aws-parameter-bulk get / --prefixpath > .env
 
# Go into the file to add/delete/access/modify the parameters
 
# Sync your local changes back to AWS parameter store
AWS_PROFILE=<YOUR_AWS_PROFILE> \
AWS_REGION=<YOUR_AWS_REGION> \
aws-parameter-bulk save .env

3) Check!

• Replace <PARAMETER_NAME> with your own parameter name

aws ssm get-parameters-by-path \
	--path / \
	--recursive \
	--with-decryption \
| jq '.Parameters[] | select(.Name | test("<parameter_name>"))'

Tip

test("<parameter_name_1>|<parameter_name_2>") shows 2 parameters. With this syntax, you can select more than 2 parameters
