GQCP devops

DevOps aims to shorten the development life cycle by providing support for continuous integration, delivery and deployment.

Integration: Github

Github provides hosting of Git repo’s together with collaborative features such as bug tracking, feature requests, task management and project management.

Delivery: Github Actions

Github Actions automate the build and test stages. You can enable a ready to go Github Action by putting the relevant *.yml file in the .github/workflows/ directory of your repo. You can check the status of this actions in the actions tab of the Github repo in question.

Deployment: Conda and Docker

Conda and Anaconda Cloud

Conda is a package manager for software. You have to provide three building blocks for this software to be built:

• build.sh: a build script.

• meta.yaml: describes the package and the requirements that need to be met on build, host and run systems.

• conda_build_config.yaml: sets the specific versions of the requirements used. Should be kept constant over the intended software environment.

For easy distribution, built packages can be uploaded to Anaconda Cloud.

Docker

Docker provides a platform as a service and is ideally suited to provide development environments. Docker only requires a Dockerfile, which contains all steps needed to provision the container.

For easy distribution, images can be uploaded to Docker Hub.
