Usage

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

Download parameters as a json file

$ larson get-parameters /a/parameter/store/path/ > ./example.json

$ cat ./example.json

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

source larson_json_to_vars ./example.json

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

$ larson put-parameters /a/parameter/store/path/ --input-file=./new-values.json

pip install larson
