The AWS SSM Param Store can be a great way to
fetch values that you may need to keep secret. Simply using the
aws-cli you can add this to a script or even just import the right package for your language.
This post will focus on just the
aws ssm put-parameter \ --name "staging_key" \ --type "String" \ --value "the-bees-knees"
aws ssm get-parameter \ --name "staging_key"
Now the bread and butter is when you need to fetch multiple variables. The best way to do so is with hierarchy, for example,
/stage/$STAGE-API-KEY. If all your keys for a given environment have
/stage/* then you can fetch them all in one quick transaction using
aws ssm get-parameters-by-path \ --path "/stage"
I wrote this quick post because of just how useful this was and somewhat hidden for me, as at the time I had not seen this similar functionality in the AWS Console.
