Warning: experimental

This is an experimental library, and is currently unsupported.

Usage

gorson loads parameters from AWS ssm parameter store, and adds them as shell environment variables.

Download parameters from parameter store as a json file

gorson get /a/parameter/store/path/ > ./example.json

$ cat ./example.json

{
    "alpha": "the_alpha_value",
    "beta": "the_beta_value",
    "delta": "the_delta_value"
}

There's also a --format flag to pass in which format you want the parameters to export as.

gorson get --format yaml /a/parameter/store/path/ > ./example.yml

$ cat ./example.yml

alpha: "the_alpha_value"
beta: "the_beta_value"
delta: "the_delta_value"

gorson get --format env /a/parameter/store/path/ > ./.env

$ cat ./.env

alpha="the_alpha_value"
beta="the_beta_value"
delta="the_delta_value"

Load parameters as environment variables from a json file

source <(gorson load ./example.json)

$ env | grep 'alpha\|beta\|delta'
alpha=the_alpha_value
delta=the_delta_value
beta=the_beta_value

Upload parameters to parameter store from a json file

gorson put /a/parameter/store/path/ --file=./new-values.json

Delete parameter difference on put

$ gorson put /a/parameter/store/path/ --file=./different-values.json --delete

The following are not present in the file, but are in parameter store:
/a/parameter/store/path/gamma
Are you sure you'd like to delete these parameters?
Type yes to proceed:

Auto-approve prompts

If you would like to answer 'yes' to any prompts that require it, append --auto-approve.

Deactivate color

If you would prefer the output of commands to be colorless, append --no-color.
