Installation

We will guide you through installation of wash, the wasmCloud Shell, which gives you the tools to install, run, and develop with wasmCloud.

curl -s https://packagecloud.io/install/repositories/wasmcloud/core/script.deb.sh | sudo bash
sudo apt install wash

curl -s https://packagecloud.io/install/repositories/wasmcloud/core/script.rpm.sh | sudo bash
sudo dnf install wash

snap install wash --devmode --edge

brew tap wasmcloud/wasmcloud
brew install wash

choco install wash

If your platform isn't listed, wash can be installed with cargo and a properly installed Rust toolchain.

cargo install wash-cli

The wash repository is open source on GitHub and can be cloned and built locally directly. With a Rust toolchain, wash is easy to build from source

git clone https://github.com/wasmcloud/wash.git
cd wash
cargo build --release
./target/release/wash

caution

If you only use Docker Compose without installing wash, you'll only be able to interact with wasmCloud via the Web Dashboard.

Download the sample Docker Compose file and put it into your work directory. This compose file will run NATS, a local OCI registry, a Redis container, Grafana and Tempo for OTEL tracing, and the wasmcloud_host container. In this format it's easy to run all the necessary services for a wasmCloud host with only a docker installation.

With the docker-compose.yml file in the current directory, start the processes with

docker compose up

The host will run until you type ctrl-c or close the terminal window. To start the docker compose process in the background, add a -d flag:

docker compose up -d

If the wasmCloud host is running in docker in the background, you can view its logs (live) with

docker logs -f wasmcloud

That's it! Let's move on to Getting started

Once wash is installed, simply run wash up. This will download and start NATS and wasmCloud for you, printing logs to the terminal. You can exit at any time by pressing ctrl-c. Now, you're ready to proceed onto Getting started.
