Ultraman (Rust Foreman)

Manage Procfile-based applications.

This is a foreman rust implementation made with ruby.
So the specifications are exactly the same as ruby ​​foreman.

🚉 Platform

• Linux
• macOS
• windows (Do not Support)

🦀 Installation

Download binary

Download from release page, and extract to the directory in PATH.

make install_man

Homebrew

brew tap yukihirop/homebrew-tap
brew install ultraman

💻 Command

$ ultraman --help
ultraman 0.3.0
Ultraman is a manager for Procfile-based applications. Its aim is to abstract away the details of the Procfile format,
and allow you to either run your application directly or export it to some other process management format.

USAGE:
    ultraman [SUBCOMMAND]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    check     Validate your application's Procfile
    export    Export the application to another process management format
    help      Prints this message or the help of the given subcommand(s)
    run       Run a command using your application's environment
    start     Start the application

🚀 Tutorial

Create a Procfile like the one below

exit_0: sleep 5 && echo 'success' && exit 0;
exit_1: sleep 5 && echo 'failed' && exit 1;
loop: while :; do sleep 1 && echo 'Hello World'; done;

Then execute the following command

ultraman start

$ ultraman start
02:22:34 system    | exit_1.1  start at pid: 23374
02:22:34 system    | loop.1    start at pid: 23375
02:22:34 system    | exit_0.1  start at pid: 23376
02:22:35 loop.1    | Hello World
02:22:36 loop.1    | Hello World
02:22:37 loop.1    | Hello World
02:22:38 loop.1    | Hello World
02:22:39 exit_1.1  | failed
02:22:39 exit_0.1  | success
02:22:39 exit_0.1  | exited with code 0
02:22:39 system    | sending SIGTERM for exit_1.1  at pid 23374
02:22:39 system    | sending SIGTERM for loop.1    at pid 23375
02:22:39 exit_1.1  | exited with code 1
02:22:39 system    | sending SIGTERM for loop.1    at pid 23375
02:22:39 loop.1    | terminated by SIGTERM

If ctrl-c is detected within 5 seconds, SIGTERM will be sent to all child processes and the process will be killed.

$ ultraman start
02:23:58 system    | loop.1    start at pid: 23588
02:23:58 system    | exit_0.1  start at pid: 23589
02:23:58 system    | exit_1.1  start at pid: 23590
02:23:59 loop.1    | Hello World
02:24:00 loop.1    | Hello World
02:24:01 loop.1    | Hello World
^C02:24:01 system  | SIGINT received, starting shutdown
02:24:01 system    | sending SIGTERM to all processes
02:24:01 system    | sending SIGTERM for loop.1    at pid 23588
02:24:01 system    | sending SIGTERM for exit_0.1  at pid 23589
02:24:01 system    | sending SIGTERM for exit_1.1  at pid 23590
02:24:01 exit_1.1  | terminated by SIGTERM
02:24:01 exit_0.1  | terminated by SIGTERM
02:24:01 loop.1    | terminated by SIGTERM

🌎 Environment

• rustc 1.74.0 (79e9716c9 2023-11-13) (Homebrew)
• cargo 1.74.0

⚾️ Example

💪 Development

cargo run start
cargo run run <app>
cargo run export <format> <location>

If you want to see help In that case, you can check with the following command

cargo run -- --help
cargo run start --help
cargo run run --help
cargo run export --help

✍️ Test

src/signal.rs usually ignores tests that need to send a SIGINT to kill the process as it can interrupt other tests

cargo test
cargo test -- --ignored # unit test about src/signal.rs
# or
cargo test -- --nocapture

👽 Development in Docker

It is useful when a person developing on mac wants to check the operation on ubuntu.

{
    docker-compose build
    docker-compose up -d
    docker exec -it ultraman_test_ubuntu_1 /bin/bash
}

# in docker
root@65241fa12c67:/home/app# make test

🧔 Man
