Usage

Inside your server with aws credentials, just type SSM2ENV_PREFIX=testapi.prod ssm2env [-v] .

This command will generate the script to export the environments.

After reproduction a process, init script will be called and it'll export above variables.

If you'd set envs immediately, just call the raw script file. source /etc/profile.d/loadenv_fromssm.sh
