autamus/chef-wasm

A web interface to generate Dockerfile's for custom container images. Chef Autamus at your service!

Chef wasm

Chef wasm uses https://github.com/autamus/chef in order to generate a web interface to create a Dockerfile. Chef Autamus at your service!

This is an ideal approach if you want to use spack packages but you don't want to wait for them to build (which can take forever!). Autamus containers can dump them easily into a spack install. Note that since we are combining multiple containers, there may be issues that arise! This is early in development and experimental. Please open an issue if you have any trouble.

Usage

1. Interface

Browse to the interface at https://autamus.io/chef-wasm/ and then select the software packages (and versions) that you want to install! Since this is spack, you are totally allowed to install different versions of things.

Once you have your Dockerfile, click the "Download" button to save it!

2. Build

On your local machine, you can build! It's recommended to use DOCKER_BUILDKIT for faster builds.

export DOCKER_BUILDKIT=1
$ docker build -t chef-stack .

You might want to save the Dockerfile to version control if desired, or build with a CI recipe. This might be desired if you eventually want to pull down to a Singularity or Podman container on an HPC resource. Please open an issue if you would like a CI example added to this repository.

3. Interact

When you shell into your container, you will be in the spack root.

$ docker run -it chef-stack
# /opt/spack

And spack is available to you!

# which spack
/opt/spack/bin/spack

To see your installed software, use spack find

$ spack find
root@62b0820b3524:/opt/spack# spack find
==> 61 installed packages

And then to load any particular piece of software (meaning it gets added to your path):

# setup your environment
$ . /opt/spack/share/spack/setup-env.sh

# load Python
root@62b0820b3524:/opt/spack# spack load [email protected]

# Did we load it?
root@62b0820b3524:/opt/spack# which python
/opt/spack/opt/spack/linux-ubuntu18.04-x86_64/gcc-7.5.0/python-3.9.5-kykqwyent2svlspsvehqpu4xdgcp54z5/bin/python

/opt/spack# python --version
Python 3.9.5

That's it!

Development

You'll first need to generate a chef.wasm file under docs.

$ make

You can then deploy this on GitHub pages, or run a local webserver.

$ cd docs
$ python -m http.server 9999
