Wave CLI

Command line tool for Wave containers provisioning service.

Summary

Wave allows augmenting existing containers and building containers on demand so that it can be used in your Docker (replace-with-your-own-fav-container-engine) workflow.

Features

• Build container images on-demand for a given container file (aka Dockerfile);
• Build container images on-demand based on one or more Conda packages;
• Build container images on-demand based on one or more Spack packages;
• Build container images for a specified target platform (currently linux/amd64 and linux/arm64);
• Push and cache built containers to a user-provided container repository;
• Build Singularity native containers both using a Singularity spec file, Conda package(s) and Spack package(s);
• Push Singularity native container images to OCI-compliant registries;

Installation

Binary download

Download the Wave pre-compiled binary for your operating system from the GitHub releases page and give execute permission to it.

Homebrew (Linux and macOS)

If you use Homebrew, you can install like this:

 brew install seqeralabs/tap/wave-cli

Get started

1. Create a basic Dockerfile file (or use an existing one)

   cat << EOF > ./Dockerfile
   FROM alpine 
   
   RUN apk update && apk add bash cowsay \
           --update-cache \
           --repository https://alpine.global.ssl.fastly.net/alpine/edge/community \
           --repository https://alpine.global.ssl.fastly.net/alpine/edge/main \
           --repository https://dl-3.alpinelinux.org/alpine/edge/testing
   EOF

2. Run it provisioning the container on-the-fly

   docker run --rm $(wave -f ./Dockerfile) cowsay "Hello world"

Examples

Augment a container image

1. Create a directory holding the files to be added to your container:

   mkdir -p new-layer/usr/local/bin
   printf 'echo Hello world!' > new-layer/usr/local/bin/hello.sh 
   chmod +x new-layer/usr/local/bin/hello.sh

2. Run the container via Wave

   container=$(wave -i alpine --layer new-layer)
   docker run $container sh -c hello.sh

Build a container with Dockerfile

1. Create a Dockerfile for your container image:

   cat << EOF > ./Dockerfile
   FROM alpine 
   ADD hello.sh /usr/local/bin/
   EOF

2. Create the build context directory:

   mkdir -p build-context/
   printf 'echo Hello world!' > build-context/hello.sh 
   chmod +x build-context/hello.sh 

3. Build and run the container on the fly:

   container=$(wave -f Dockerfile --context build-context)
   docker run $container sh -c hello.sh

Build a Conda multi-packages container

container=$(wave --conda-package bamtools=2.5.2 --conda-package samtools=1.17)
docker run $container sh -c 'bamtools --version && samtools --version'

Build a container by using a Conda environment file

1. Create the Conda environment file:

   cat << EOF > ./conda.yaml
   name: my-conda
   channels:
   - defaults
   - bioconda
   - conda-forge
   dependencies:
   - bamtools=2.5.2
   - samtools=1.17
   EOF

2. Build and run the container using the Conda environment:

   container=$(wave --conda-file ./conda.yaml)
   docker run $container sh -c 'bamtools --version'

Build a container by using a Conda lock file

container=$(wave --conda-package https://prefix.dev/envs/pditommaso/wave/6x60arx3od13/conda-lock.yml)
docker run $container cowpy 'Hello, world!'

Build a Conda package container arm64 architecture

container=$(wave --conda-package fastp --platform linux/arm64)
docker run --platform linux/arm64 $container sh -c 'fastp --version'

Build a Spack package container

container=$(wave --spack-package cowsay)
docker run $container sh -c 'cowsay Hello world!'

Build a Singularity container using a Conda package and pushing to a OCI registry

container=$(wave --singularity --conda-package bamtools=2.5.2 --build-repo docker.io/user/repo --freeze --await)
singularity exec $container bamtools --version

Development

1. Install GraalVM-Java 21.0.1

   sdk install java 21.0.1-graal

   or if it's already installed

   sdk use java 21.0.1-graal

2. Compile & run tests

   ./gradlew check

3. Native compile

   ./gradlew app:nativeCompile

4. Run the native binary

   ./app/build/native/nativeCompile/wave --version
