wasmcloud - getting started

First ensure you have installed the right tools. The easier way to do this is using ubuntu 24.04 that has the right tooling versions. 

Install wash

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

apt-get update

apt install wash

Check the version you have installed.

wash --version

Start to install the core components

install sudo apt install build-essential

install rustc 

install golang manually as wasmcloud requires golang version 1.23.

export GO_VERSION="1.23.4"

export GO_ARCH="amd64"

curl -O -L "https://golang.org/dl/go${GO_VERSION}.linux-${GO_ARCH}.tar.gz"

tar -xf "go${GO_VERSION}.linux-${GO_ARCH}.tar.gz"

sudo chown -R root:root ./go

mv -v go /usr/local

export PATH=$PATH:/usr/local/go/bin

Install tinygo

export TINYGO_VERSION="0.34.0"

export TINYGO_ARCH="amd64"

curl -O -L "https://github.com/tinygo-org/tinygo/releases/download/v${TINYGO_VERSION}/tinygo_${TINYGO_VERSION}_${TINYGO_ARCH}.deb"

sudo dpkg -i tinygo_${TINYGO_VERSION}_${TINYGO_ARCH}.deb

export PATH=$PATH:/usr/local/bin

Install WASM tools

cargo install wasm-tools

Once you have all the tools, lets start with creating an hello world program

wash new component hello --template-name hello-world-tinygo

cd hello

Try to do a golang build. 

go build . 

If you have issue, you need to resolve it here. Next, try to do

wash build

wash dev
