WebAssembly on Kubernetes

1. minikube

   1 91 30,257 9.9 Go

   Run Kubernetes locally

   

   💡 ingress is an addon maintained by Kubernetes. For any concerns contact minikube on GitHub. You can view the list of minikube maintainers at: https://github.com/kubernetes/minikube/blob/master/OWNERS 💡 After the addon is enabled, please run "minikube tunnel" and your ingress resources would be available at "127.0.0.1" ▪ Using image registry.k8s.io/ingress-nginx/kube-webhook-certgen:v1.4.4 ▪ Using image registry.k8s.io/ingress-nginx/kube-webhook-certgen:v1.4.4 ▪ Using image registry.k8s.io/ingress-nginx/controller:v1.11.3 🔎 Verifying ingress addon... 🌟 The 'ingress' addon is enabled

2. InfluxDB

   influxdata.com featured

   InfluxDB high-performance time series database. Collect, organize, and act on massive volumes of high-resolution data to power real-time intelligent systems.

   

3. wasm-kubernetes

   2 2 0 5.7 Rust

   

   The use case should be more advanced than Hello World to highlight the capabilities of WebAssembly. I've implemented an HTTP server mimicking a single endpoint of the excellent httpbin API testing utility. The code itself is not essential as the post is not about Rust, but in case you're interested, you can find it on GitHub. I add a field to the response to explicitly return the underlying approach, respectively native, embed, or runtime.

4. wasi_tokio

   3 1 1 3.6

   A runtime for writing reliable asynchronous applications with Rust. Provides I/O, networking, scheduling, timers, ...

   

   [patch.crates-io] tokio = { git = "https://github.com/second-state/wasi_tokio.git", branch = "v1.36.x" } #1-2 socket2 = { git = "https://github.com/second-state/socket2.git", branch = "v0.5.x" } #1 [dependencies] tokio = { version = "1.36", features = ["rt", "macros", "net", "time", "io-util"] } #2 axum = "0.8" serde = { version = "1.0.217", features = ["derive"] }

5. socket2

   4 1 0 4.2 Rust

   Advanced configuration options for sockets. (by second-state)

   

   [patch.crates-io] tokio = { git = "https://github.com/second-state/wasi_tokio.git", branch = "v1.36.x" } #1-2 socket2 = { git = "https://github.com/second-state/socket2.git", branch = "v0.5.x" } #1 [dependencies] tokio = { version = "1.36", features = ["rt", "macros", "net", "time", "io-util"] } #2 axum = "0.8" serde = { version = "1.0.217", features = ["derive"] }

6. runwasi

   5 9 1,163 9.8 Rust

   Facilitates running Wasm / WASI workloads managed by containerd

   

   sudo apt-get update sudo apt-get install -y git git clone https://github.com/containerd/runwasi.git cd runwasi ./scripts/setup-linux.sh make build-wasmedge INSTALL="sudo install" LN="sudo ln -sf" make install-wasmedge

7. vcluster

   6 79 10,609 9.8 Go

   vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.

   

   To compare the approaches and test our work, we can use the minikube ingress addon and vCluster. The former offers a single access point for all three workloads, native, embed, and runtime, while vCluster isolates workloads from each other in their virtual cluster.
