This guide shows how to install Krustlet.
From the Binary Releases
Every release of Krustlet provides compiled releases for a variety of Operating Systems. These compiled releases can be manually downloaded and installed. Please note these instructions will work on Linux, MacOS, and Windows (in PowerShell)
- Download your desired version from the releases page
- Unpack it (
tar -xzf krustlet-v0.6.0-linux-amd64.tar.gz)
- Find the desired Krustlet provider in the unpacked directory, and move it to
its desired destination somewhere in your
mv krustlet-wasi /usr/local/bin/on unix-like systems or
mv krustlet-wasi.exe C:\Windows\system32\on Windows)
From there, you should be able to run the client in your terminal emulator. If
your terminal cannot find Krustlet, check to make sure that your
environment variable is set correctly.
If you’d like to validate the download, checksums can be downloaded from https://krustlet.blob.core.windows.net/releases/checksums-v0.6.0.txt
As of Krustlet 0.4, there are now Windows builds available. However, there are some caveats. The underlying dependencies used to support Windows do not support certs with IP SANs (subject alternate names). Because of this, the serving certs requested during bootstrap will not work for local development options like minikube or KinD as they do not have an FQDN. So these builds can only be used in environments with an actual hostname/FQDN accessible to the Kubernetes cluster.
From Canary Builds
“Canary” builds are versions of Krustlet that are built from
main. They are
not official releases, and may not be stable. However, they offer the
opportunity to test the cutting edge features before they are released.
Here are links to the common builds:
- checksum file
- 64-bit Linux (AMD architecture)
- 64-bit Linux (ARM architecture)
- 64-bit macOS (AMD architecture)
- 64-bit Windows
Compiling from Source
If you want to compile Krustlet from source, you will need to follow the developer guide.
After installing Krustlet, if you’d like to get started and see something
running, go checkout any one of the demos. Each of them has a
prebuilt WebAssembly module stored in a registry and a Kubernetes manifest that
