README

🕊️ peace – zero stress automation

Crates.io docs.rs CI Coverage Status

peace is a framework to build empathetic and forgiving software automation.

See:

  • peace.mk for the project vision.

  • Background for the motivation to create this framework.

  • Operations UX for a book about the dimensions considered during peace's design and development.

Guiding Principles

  • A joy to use.

  • Ergonomic API and guidance to do the right thing.

  • Understandable output.

Features

Symbol Meaning
🟢 Works well
🟡 Partial support
Planned
🔵 Compatible by design
🟣 Works, "fun idea"
  • 🟢 Idempotent: Multiple invocations result in the goal outcome.
  • 🟢 Clean: Every item creation is paired with how it is cleaned up.
  • 🟢 Understandable: Progress is shown at an understandable level of detail.
  • 🔵 Understandable: Error reporting is compatible with miette.
  • 🟡 Interruptible: Execution can be interrupted.
  • 🟢 Resumable: Automation resumes where it was interrupted.
  • 🟢 Diffable: States and diffs are serialized as YAML.
  • 🟢 Efficient: Tasks are concurrently executed via fn_graph.
  • 🟢 Namespaced: Profile directories isolate environments from each other.
  • 🟢 Type Safe: Items and parameters are defined in code, not configuration.

Roadmap

  • 🟢 Define items to manage with automation.
  • 🟢 Define dependencies between items.
  • 🟢 Define "apply" logic.
  • 🟢 Define "clean up" logic.
  • 🟢 Discover current and goal states.
  • 🟢 Define diff calculation between states.
  • 🟢 Store and recall parameters across commands.
  • 🟢 Diff states between multiple profiles.
  • 🟢 Type-safe referential parameters -- specify usage of values generated during automation as parameters to subsequent items.
  • 🟡 Feature-gated incremental functionality.
  • 🟡 Off-the-shelf support for common items.
  • 🟡 Dry run.
  • 🟣 WASM support.
  • ⚫ Cancel-safe interruption via tokio-graceful-shutdown.
  • ⚫ Secure-by-design Support: Encrypted value storage, decrypted per execution / time based agent.
  • ⚫ Tutorial for writing a software lifecycle management tool.
  • ⚫ Built-in application execution methods -- CLI, web service.
  • peace binary for configuration based workflows.
  • ⚫ Web based UI with interactive graph.
  • ⚫ Agent mode to run peace on servers (Web API invocation).

Further ideas:

  • Back up current state.
  • Restore previous state.
  • Telemetry / metrics logging for analysis.

Examples

Examples are run using --package instead of --example, as each example is organized as its own crate.

cargo run --package $example_name --all-features

# e.g.
cargo build --package download --all-features
cargo run -q --package download --all-features -- init https://ifconfig.me ip.json

for cmd in status goal diff ensure ensure diff clean clean diff
do
    printf "=== ${cmd} ===\n"
    cargo run -q --package download --all-features -- --format text $cmd
    printf '\n'
done

# Look at metadata that Peace has saved
find .peace -type f -exec bash -c 'echo \# {}; cat {}; echo' \;

# Clean up the metadata directory
rm -rf .peace

WASM

The download example can be built as a web assembly application using wasm-pack:

cd examples/download
wasm-pack build --target web

In the examples/download directory, start an HTTP server, and open http://localhost:8000/:

python3 -m http.server 8000 # or
simple-http-server --nocache --port 8000 -i
