Adding `peace_core` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add peace_core

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

peace_core = "0.0.15"

The peace_core library will be automatically available globally. Read the peace_core library documentation.

Back to the crate overview.

Readme

🕊️ peace – zero stress automation

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.
🟢 Cancel-safe interruption.
🟡 Feature-gated incremental functionality.
🟡 Off-the-shelf support for common items.
🟡 Dry run.
🟣 WASM support.
🟡 Web based UI with interactive graph.
⚫ Run command with subset of items.
⚫ Params specification: Read values from other flows.
⚫ Flow versions: Support migrating environment deployed using previous flow version.
⚫ 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.
⚫ 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.

download example

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

envman example

Install cargo-leptos.
```
cargo install --locked cargo-leptos
```

Build the envman example:

# defined in .cargo/config.toml
cargo envman_build_debug

Copy artifacts to a temporary directory:

demo_dir=/tmp/demo/envman
test -d "${demo_dir}" || mkdir -p "${demo_dir}"
cp ./target/debug/envman "${demo_dir}"
cp ./target/web/envman/pkg "${demo_dir}"

Switch to the demo directory:

demo_dir=/tmp/demo/envman
cd "${demo_dir}"

Make sure you have AWS credentials set up in ~/.aws/credentials.

Run the appropriate envman commands:

Initialize a project:

# initialize a project to download from `azriel91/web_app`
./envman init \
  --type development \
  --flow deploy \
  demo_1 azriel91/web_app 0.1.1

Status / Goal / Diff:

./envman status
./envman goal
./envman diff

Deploy / Clean

./envman deploy
./envman deploy --format json
./envman deploy --format none

./envman clean
./envman clean --format json
./envman clean --format none

You can also interrupt the deploy/clean process.

Run the web interface:
```
./envman web
```
