# Async::Container
Provides containers which implement parallelism for clients and servers.
[](https://github.com/socketry/async-container/actions?workflow=Test)
## Features
- Supports multi-process, multi-thread and hybrid containers.
- Automatic scalability based on physical hardware.
- Direct integration with [systemd](https://www.freedesktop.org/software/systemd/man/sd_notify.html) using `$NOTIFY_SOCKET`.
- Internal process readiness protocol for handling state changes.
- Automatic restart of failed processes.
## Usage
Please see the [project documentation](https://socketry.github.io/async-container/) for more details.
- [Getting Started](https://socketry.github.io/async-container/guides/getting-started/index) - This guide explains how to use `async-container` to build basic scalable systems.
## Releases
Please see the [project releases](https://socketry.github.io/async-container/releases/index) for all releases.
### v0.24.0
- Add support for health check failure metrics.
### v0.23.0
- [Add support for `NOTIFY_LOG` for Kubernetes readiness probes.](https://socketry.github.io/async-container/releases/index#add-support-for-notify_log-for-kubernetes-readiness-probes.)
### v0.21.0
- Use `SIGKILL`/`Thread#kill` when the health check fails. In some cases, `SIGTERM` may not be sufficient to terminate a process because the signal can be ignored or the process may be in an uninterruptible state.
### v0.20.1
- Fix compatibility between Async::Container::Hybrid and the health check.
- Async::Container::Generic\#initialize passes unused arguments through to Async::Container::Group.
### v0.20.0
- Improve container signal handling reliability by using `Thread.handle_interrupt` except at known safe points.
- Improved logging when child process fails and container startup.
- [Add `health_check_timeout` for detecting hung processes.](https://socketry.github.io/async-container/releases/index#add-health_check_timeout-for-detecting-hung-processes.)
