Kuasar v0.2.0

Quick Start

Wellcome to the v0.2.0 release of Kuasar!

To make a better user experience, excutable binaries(sandboxer, containerd) and their supported files(containerd config file and image/kernel of Cloud Hypervisor) are packed in the attached artifacts. If you got error in building Kuasar, come and find what you need in this artifacts. Additionally, a source code package including vendor code is also provieded, allowing to build without network.

tar xzvf kuasar-v0.2.0-linux-amd64.tar.gz
mkdir -p /var/lib/kuasar
cd kuasar-v0.2.0/
cp kuasar.img vmlinux.bin config_clh.toml /var/lib/kuasar

Please use our config.toml by passing flag a -c config.toml to contaienrd, the config.toml is the minimal config for running containerd with Kuasar.

Notable Updates

Support of Wasmtime

Wasmtime sandbox has been integrated since Kuasar v0.2.0, as planned in Roadmap before. Users can run a container that use wasmtime as the WebAssembly runtime. (#47)

Limit and Stat Resources for WasmEdge Container

Container resources of CPU/memory/... are basic metrics for kubernetes cluster monitor and scheduler. We have limited the sandboxer and wasmEdge process(including container process) into container cgroup so that their metrics can be collected and exported. (#74, #87)

Add Release workflow

Add a new github action workflow for release, binaries and vendor codes could be packed automatically. (#95)
