## Introduction
This is a topic to provide additional information to my [EGU26 talk: Modern tools to scale the building, testing and deployment of scientific software](https://meetingorganizer.copernicus.org/EGU26/EGU26-8712.html).

## Build CI
The build-ci workflow referenced is available at this GitHub repo:
> **[GitHub - ACCESS-NRI/build-ci: Reusable github workflows for CI across ACCESS-NRI...](https://github.com/ACCESS-NRI/build-ci)**
>
> Reusable github workflows for CI across ACCESS-NRI projects. Admins: @CodeGat, @aidanheerdegen
An example of it’s use is the MOM5 (ocean model component) repository
> **[GitHub - ACCESS-NRI/MOM5: The Modular Ocean Model](https://github.com/ACCESS-NRI/MOM5)**
>
> The Modular Ocean Model
which has [scheduled tests](https://github.com/ACCESS-NRI/MOM5/tree/master/.github/build-ci/manifests/scheduled) and [pull request (CI) tests](https://github.com/ACCESS-NRI/MOM5/tree/master/.github/build-ci/manifests/pr) that use this action.
The ACCESS spack packages repository also uses this action for CI testing of modifications to the spack packages
> **[GitHub - ACCESS-NRI/access-spack-packages: Spack package repository maintained by ACCESS-NRI....](https://github.com/ACCESS-NRI/access-spack-packages/)**
>
> Spack package repository maintained by ACCESS-NRI. Admins: @CodeGat @harshula
As well as a workflow dispatch interface to test _all_ packages against new versions of [spack](https://github.com/spack/spack) and our [spack configuration](https://github.com/ACCESS-NRI/spack-config).
## Build CD
The build-cd workflow referenced is available in this GitHub repo:
> **[GitHub - ACCESS-NRI/build-cd: Deployment configurations and workflows. Admins:...](https://github.com/ACCESS-NRI/build-cd)**
>
> Deployment configurations and workflows. Admins: @CodeGat, @aidanheerdegen
The ACCESS-ESM1.6 deployment repository referenced in the talk utilises this workflow:
> **[GitHub - ACCESS-NRI/ACCESS-ESM1.6: The ACCESS Earth System Model (ACCESS-ESM) Version...](https://github.com/ACCESS-NRI/ACCESS-ESM1.6)**
>
> The ACCESS Earth System Model (ACCESS-ESM) Version 1.6 is a fully-coupled global climate model that includes atmoshpere, land, ocean, sea ice, ocean biogeochemistry and land biogeochemistry components, linked together by a coupler.
And an example of a pull request workflow, with associated pre-release builds, is [PR #181 which changed the coupler code to use a local fork](https://github.com/ACCESS-NRI/ACCESS-ESM1.6/pull/181).
The deployment workflow automatically adds provenance information to our [model release database](https://reporting.access-nri-store.cloud.edu.au/release-provenance/releases).
This workflow is also used in two other repositories to provide general purposes software deployments
> **[GitHub - ACCESS-NRI/model-tools: Repository to deploy tools used in conjunction...](https://github.com/ACCESS-NRI/model-tools)**
>
> Repository to deploy tools used in conjunction with ACCESS models
> **[GitHub - ACCESS-NRI/system-tools: Repository to deploy system tools to HPC](https://github.com/ACCESS-NRI/system-tools)**
>
> Repository to deploy system tools to HPC
## Spack infrastructure
We maintain a [spack fork](https://github.com/ACCESS-NRI/spack) to streamline configuring spack for deploying to [gadi@NCI](https://nci.org.au/media/images/gadi-supercomputer-0).
Our spack configuration is available in the [ACCESS-NRI/spack-config](https://github.com/ACCESS-NRI/spack-config) repo
> **[GitHub - ACCESS-NRI/spack-config: Shared spack configuration](https://github.com/ACCESS-NRI/spack-config)**
