What is Minder?

Minder by Stacklok is an open source platform that helps development teams and open source communities build more secure software, and prove to others that what they’ve built is secure. Minder helps project owners proactively manage their security posture by providing a set of checks and policies to minimize risk along the software supply chain, and attest their security practices to downstream consumers.

Minder allows users to enroll repositories and define policy to ensure repositories and artifacts are configured consistently and securely. Policies can be set to alert only or auto-remediate. Minder provides a predefined set of rules and can also be configured to apply custom rules.

Minder can be deployed as a Helm chart and provides a CLI tool ‘minder’. Stacklok, the company behind Minder, also provides a free-to-use hosted version of Minder (for public repositories only). Minder is designed to be extensible, allowing users to integrate with their existing tooling and processes.

Features

Repo configuration and security: Simplify configuration and management of security settings and policies across repos.
Proactive security enforcement: Continuously enforce best practice security configurations by setting granular policies to alert only or auto-remediate.
Artifact attestation: Continuously verify that packages are signed to ensure they’re tamper-proof, using the open source project Sigstore.
Dependency management: Manage dependency security posture by helping developers make better choices and enforcing controls. Minder is integrated with Trusty by Stacklok to enable policy-driven dependency management based on the risk level of dependencies.

Public instance

Your friends at Stacklok have set up a public instance of Minder that you can use for free. The Minder CLI tool (minder) from our official releases is configured to use this instance by default. Follow Stacklok's Minder Getting Started Guide to quickly try out Minder's features without having to build and deploy OSS Monder.

Note that it's not possible to register private repositories. If you'd like to use Minder with private repositories, feel free to contact us! We'd be thrilled to help you out.

Getting Started (< 1 minute)

Getting up and running with Minder takes under a minute and is as easy as:

Installing Minder
Logging in to Minder
and running minder quickstart to create your first profile.

In just a few seconds, you will register your repositories and enable secret scanning protection for all of them! 🤯

Installation

Choose your preferred method to install minder:

MacOS (Homebrew)

Make sure you have Homebrew installed.

brew install stacklok/tap/minder

Windows (Winget)

Make sure you have Winget installed.

Build it from source

Build minder and minder-server from source by following the build from source guide.

Logging in to Minder

To use minder with the public instance of Minder (api.stacklok.com), log in by running:

minder auth login

Upon completion, you should see that the Minder Server is set to api.stacklok.com.

Run Minder quickstart

The quickstart command guides you through creating your first profile in Minder, register your repositories, and enabling secret scanning protection for your repositories in seconds.

To do so, run:

minder quickstart

This will prompt you to enroll your provider, select the repositories you'd like, create the secret_scanning rule type and create a profile which enables secret scanning for the selected repositories.

To see the status of your profile, run:

minder profile_status list --profile quickstart-profile --detailed

You should see the overall profile status and a detailed view of the rule evaluation statuses for each of your registered repositories.

Minder will continue to keep track of your repositories and will ensure to fix any drifts from the desired state by using the remediate feature or alert you, if needed, using the alert feature.

Congratulations! 🎉 You've now successfully created your first profile!

What's next?

You can now continue to explore Minder's features by adding or removing more repositories, create more profiles with various rules, and much more. There's a lot more to Minder than just secret scanning.

The secret_scanning rule is just one of the many rule types that Minder supports.

You can see the full list of ready-to-use rules and profiles maintained by Minder's team here - stacklok/minder-rules-and-profiles.

In case there's something you don't find there yet, Minder is designed to be extensible. This allows for users to create their own custom rule types and profiles and ensure the specifics of their security posture are attested to.

Now that you have everything set up, you can continue to run minder commands against the public instance of Minder where you can manage your registered repositories, create profiles, rules and much more, so you can ensure your repositories are configured consistently and securely.

Development

This section describes how to build and run Minder from source.

Build from source

Prerequisites

You'd need the following tools available - Go, Docker and Docker Compose.

Clone the repository

git clone git@github.com:stacklok/minder.git

Build

Run the following to build minder and minder-server(binaries will be present at ./bin/)

make build

To use minder with the public instance of Minder (api.stacklok.com), run:

minder auth login

Upon completion, you should see that the Minder Server is set to api.stacklok.com.

If you want to run minder against a local minder-server instance, proceed with the steps below.

Initial configuration

Create the initial configuration file for minder and minder-server. You may do so by doing.

cp config/config.yaml.example config.yaml

You'd also have to set up an OAuth2 application for minder-server to use. Once completed, update the configuration file with the appropriate values. See the documentation on how to do that - Docs.

Run `minder-server`

Start minder-server along with its dependant services (keycloak and postgres) by running:

make run-docker

Configure social login (GitHub)

minder-server uses Keycloak as an IAM. To log in, you'll need to set up a GitHub OAuth2 application and configure Keycloak to use it.

Create an OAuth2 application for GitHub here. Select New OAuth App and fill in the details. The callback URL should be http://localhost:8081/realms/stacklok/broker/github/endpoint. Create a new client secret for your OAuth2 client.

Using the client_id and client_secret you created above, enable GitHub login on Keycloak by running the following command:

make KC_GITHUB_CLIENT_ID=<client_id> KC_GITHUB_CLIENT_SECRET=<client_secret> github-login

Run minder

Ensure the config.yaml file is present in the current directory so minder can use it.

Run minder against your local instance of Minder (localhost:8090):

minder auth login

Upon completion, you should see that the Minder Server is set to localhost:8090.
