srtool cli

This project is NOT the srtool docker image that is actually used to build Substrate Wasm Runtime. This utility requires docker to be installed and running and will invoke the srtool image to help you build a Substrate runtime.

This project is a cli interface to docker to simplify using the srtool docker image. With this executable, you no longer need to set and maintain a long and complex alias, as currently described in the srtool documentation.

Install

If you previously defined srtool as an alias, you will first need to remove it first.

Clean up

If you used srtool in the past, you previously used an srtool alias. You can check with:

type srtool

If you see some output mentioning "srtool is an alias for docker run…​", you have an alias set and we need to remove it:

unalias srtool

This alias is likely set in your .bash_profile or .zshrc, make sure to remove this alias there as well.

Install

cargo install --git https://github.com/chevdor/srtool-cli

Usage

help

srtool is cli allowing to control the srtool docker image

Usage: srtool [OPTIONS] <COMMAND>

Commands:
  pull
          Simply pull the srtool image and do not run anything else
  build
          Start a new srtool container to build your runtime
  info
          Provide information about the srtool container and your repo
  version
          Show the versions of the srtool container. Use --version if you want the version of this executable
  help
          Print this message or the help of the given subcommand(s)

Options:
  -i, --image <IMAGE>
          Choose an alternative image. Beware to choose an image that is compatible with the original srtool image. Using a random image, you take the risk to NOT produce exactly the same deterministic result as srtool

          [default: docker.io/paritytech/srtool]

  -j, --json
          This option is DEPRECATED and has no effect

  -n, --no-cache
          Do not use the local cached tag value

  -e, --engine <ENGINE>
          By default, srtool-cli auto-detects whether you use Podman or Docker. You can force the engine if the detection does not meet your expectation. The default is auto and defaults to Podman.

          NOTE: Using Podman currently forces using --no-cache

          [default: auto]

  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

version

Show the versions of the srtool container. Use --version if you want the version of this executable

Usage: srtool version [OPTIONS]

Options:
  -i, --image <IMAGE>
          Choose an alternative image. Beware to choose an image that is compatible with the original srtool image. Using a random image, you take the risk to NOT produce exactly the same deterministic result as srtool

          [default: docker.io/paritytech/srtool]

  -e, --engine <ENGINE>
          By default, srtool-cli auto-detects whether you use Podman or Docker. You can force the engine if the detection does not meet your expectation. The default is auto and defaults to Podman.

info

Provide information about the srtool container and your repo

Usage: srtool info [OPTIONS] --package <PACKAGE> [PATH]

Arguments:
  [PATH]
          By default, srtool will work in the current folder. If your project is located in another location, you can pass it here

          [default: .]

Options:
  -i, --image <IMAGE>
          Choose an alternative image. Beware to choose an image that is compatible with the original srtool image. Using a random image, you take the risk to NOT produce exactly the same deterministic result as srtool

          [env: RUNTIME_DIR=]

  -e, --engine <ENGINE>
          By default, srtool-cli auto-detects whether you use Podman or Docker. You can force the engine if the detection does not meet your expectation. The default is auto and defaults to Podman.

Usage: srtool pull [OPTIONS]

Options:
  -i, --image <IMAGE>
          Choose an alternative image. Beware to choose an image that is compatible with the original srtool image. Using a random image, you take the risk to NOT produce exactly the same deterministic result as srtool

          [default: docker.io/paritytech/srtool]

  -e, --engine <ENGINE>

build

Start a new srtool container to build your runtime

Usage: srtool build [OPTIONS] --package <PACKAGE> [PATH]

Arguments:
  [PATH]
          By default, srtool will work in the current folder. If your project is located in another location, you can pass it here

          [default: .]

Options:
  -i, --image <IMAGE>
          Choose an alternative image. Beware to choose an image that is compatible with the original srtool image. Using a random image, you take the risk to NOT produce exactly the same deterministic result as srtool

          [default: docker.io/paritytech/srtool]

  -p, --package <PACKAGE>
          Provide the runtime such as kusama-runtime, polkadot-runtime, etc...

          [env: PACKAGE=]

  -j, --json
          Enable json output, same than the global --json option

  -a, --app
          Enable the "app" mode which is a mix of json output and outputting progress during the build. This flag is recommended for CI. the json output will be provided as a single line at the end in compact mode

  -e, --engine <ENGINE>
          By default, srtool-cli auto-detects whether you use Podman or Docker. You can force the engine if the detection does not meet your expectation. The default is auto and defaults to Podman.

          NOTE: Using Podman currently forces using --no-cache

          [default: auto]

  -r, --runtime-dir <RUNTIME_DIR>
          If your runtime is not in the standard location runtime/<chain_name> you can pass this args to help srtool find it

          [env: RUNTIME_DIR=]

      --build-opts <BUILD_OPTS>
          You may pass options to cargo directly here. WARNING, if you pass this value, the automatic build options for Kusama and Polkadot will not be passed and you need to take care of them manually. In general, you should never use this option unless you HAVE to

          [env: BUILD_OPTS=]

      --default-features <DEFAULT_FEATURES>
          Passing this is less involved than passing BUILD_OPTS. It allows changing the list of default features while keeping the automatic features detection. This value is useless if BUILD_OPTS is set

          [env: DEFAULT_FEATURES=]

      --profile <PROFILE>
          The default profile to build runtimes is always `release`. You may override the default with this flag

          [env: PROFILE=]
          [default: release]

      --no-cache
          Passing this flag allows completely disabling caching. As a result, no cargo-home will be mounted to the srtool image. There is no known issue with having the cache ON, this is why it is the default

      --root
          Run container image as root, this helps on Linux based systems

      --verbose
          Run the build script using the verbose option

  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

Contributing

If you landed here, you likely want to contribute the project. Let me thank you already. There are several ways you can help. Please start with the few notes below.

Features and issues

Whether you are reporting an issue you ran into or requesting a new feature, please open an issue here.

You know the drill: please try to provide some context information, the version you used, your OS, how to reproduce. That will greatly help solving your issue quicker.

Documentation

The documentation of this project is mainly done using AsciiDoc. Unfortunately, it takes litterally ages for Github to support THE feature that makes AsciiDoc shine. As a result, for now, this project is generating the markdwown from AsciiDoc. In short that means that you should NOT modify any .md file but change the .adoc ones and run just md to generate all the markdown.

Tooling

This project is mainly using Rust so you will need to install the Rust compiler. Make sure everything works with the latest stable version of Rust.

You will find a justfile in the root of the repo. This is to be used with just so you may want to install that as well. Just type just 😁 to discover how it can help you.

Before submitting your code, do a cargo clippy stop to make sure everything works fine. Don’t forget to cargo fmt --all as well if you want to be friend with the CI. No surprise, the test can be ran using cargo test.

You may activate the logs for the project using RUST_LOG=debug for instance.

Pull Requests

PRs are welcome. Feel free to open them early before putting too much effort (you may start with a draft). This way you can ping me (@chevdor) if you want my opinion on what and how you are putting your change together.
