In our recent [[https://www.redhat.com/en/blog/red-hat-and-webassembly][blog post]] on Web Assembly we highlighted the implementation of WASM support into the [[https://github.com/containers/crun/][crun]] Open Container Initiative (OCI) runtime. This change paves the way for Podman and OpenShift to run WASM workloads.

This demo will step through how wasm
|
|
|
|
|
|
* Install wasm runtime
|
|
|
|
|
|
* Compile crun with wasm support
|
|
|
|
To demo this capability on our own machine we need to ensure we have a version of ~crun~ available that has support for WASM. In my case I needed to download and compile a newer release including the ~as follows:
|
|
|
|
#+NAME: Compile crun with wasmedge
|
|
#+begin_src tmate
|
|
# Install compile dependencies
|
|
sudo apt-get install --yes make git gcc build-essential pkgconf libtool libsystemd-dev libprotobuf-c-dev libcap-dev libseccomp-dev libyajl-dev libgcrypt20-dev go
|
|
-md2man autoconf python3 automake
|
|
|
|
# Clone the crun source
|
|
git clone https://github.com/containers/crun && cd crun
|
|
|
|
# Compile with wasm flag
|
|
./autogen.sh
|
|
./configure --with-wasmedge
|
|
make
|
|
sudo make install
|
|
#+end_src
