Generates a systemd EnvironmentFile from AWS Systems Manager parameters.
To install via Cargo:
cargo install ssmpuller
To install from source, first, install Rust, and then run:
git clone github.com/l1na-forever/ssmpuller
cd ssmpuller
cargo install --path .
Binary releases can be found on the Releases page.
To get help, run the command:
ssmpuller --help
To generate a systemd EnvironmentFile from secure parameters stored in SSM:
ssmpuller /etc/myservice/myservice.conf MY_API_KEY
This will generate a file that can be used to set environment variables via the EnvironmentFile= directive. An example file might look like:
MY_API_KEY='secret_token_goes_here'
To make use of the generated file as part of a systemd service unit, set the EnvironmentFile= directive:
[Unit]
Description=Example systemd service
[Service]
ExecStart=/usr/bin/myservice
EnvironmentFile=/etc/myservice/myservice.conf
ssmpuller's intended usage is to bootstrap an instance's long-lived, static credentials (e.g., 3rd-party API keys) at provision time, using the IAM instance role. Wherever possible, make use of a temporary/federated credentials and the instance role credentials to make service calls. Do not use ssmpuller to manage any AWS credentials; use IAM instance roles instead.
ssmpuller is considered feature-complete, and is offered as-is. Bug reports and pull requests are most welcome!
