Simpleinfra

This repository containing the tools and automation written by the Rust infrastructure team to manage our services. Using some of the tools in this repo require privileges only infra team members have.

• ansible: Ansible playbooks to deploy our servers
• aws-creds: log into AWS with two factor authentication
• github-actions: shared actions for GitHub Actions
• setup-deploy-keys: automation for GitHub deploy keys
• terraform: Terraform configuration to deploy our cloud resources
• with-rust-key: execute commands using the Rust release signing key

setup-deploy-keys

Using Personal Access Tokens to upload to GitHub pages from CI is not great from a security point of view, as it's not possible to scope those access tokens to just that repository. Deploy keys are properly scoped, but it can be an hassle to generate and configure them.

The setup-deploy-keys tool automates most of that process. You need to setup your GitHub token in the GITHUB_TOKEN environment variable, and then run:

cargo run --bin setup-deploy-keys org-name/repo-name

The tool will generate a key, upload it to GitHub and then print an environment variable GITHUB_DEPLOY_KEY containing an encoded representation of the private key.

To use the key the easiest way is to cd into the directory you want to deploy, download this rust program, compile and run it (with the GITHUB_DEPLOY_KEY variable set).

By default the tool generates ed25519 keys, but some libraries (like git2) don't support them yet. In those cases you can generate RSA keys by passing the --rsa flag:

cargo run --bin setup-deploy-keys org-name/repo-name --rsa

with-rust-key

The with-rust-key.sh script executes a command inside a gpg environment configured to use the Rust release signing key, without actually storing the key on disk. The key is fetched at runtime from the 1password sensitive vault, and you need to have jq and the 1password CLI installed.

For example, to create a git tag for the Rust 2.0.0 release you can use:

./with-rust-key.sh gpg tag -u FA1BE5FE 2.0.0 stable

The script is designed to leave no traces of the key on the host system after it finishes, but a program with your user's privileges can still interact with the key as long as the script is running.
