  2. 4. RCS-SIS’ collaborations hosting
    Benjamin Bergia (CERN)
    27/04/2022, 09:10

    The CERN Scientific Information Service (RCS-SIS) participates in and supports multiple collaborations from the Open Science community. Some of these collaborative projects are hosted at CERN and run by the RCS-SIS Tools & Services team. To ensure a smooth development and release experience, the team rely entirely on GitOps principles and practices. All of this is made possible by using...

  3. 5. Abusing helm library chart and values for fun and profit
    Arthur Outhenin-Chalandre (CERN)
    27/04/2022, 09:35

    After sharing some context details about how I manage my personal k3s cluster. I would share a different way to create helm charts that heavily relies on a library chart and makes everything configurable via helm values. This approach is the one that the k8s-at-home project uses (https://docs.k8s-at-home.com/our-helm-charts/common-library/).

  4. 2. GitOps in MONIT
    Luca Bello (CERN)
    27/04/2022, 10:00

    MONIT follows the GitOps practices to run many internal services on Kubernetes.

    Our first iteration involved Flux1 with Helm3, for which we accumulated some months of experience.

    We recently migrated to Flux2 (still using Helm3), which we use in conjunction with a GitLab CI to manage several namespaces in multiple Kubernetes clusters for different environments (production, qa,...

  5. 1. K8s and GitOps for ATLAS Rucio operation
    Radu Carpa (CERN)
    27/04/2022, 10:40

    Recently, we migrated the Atlas Rucio installation from puppet to Kubernetes. This talk will presents how we use terraform, flux2 and helm to manage our multi-cluster installation and the applications inside the clusters.

  6. 6. GitOps for Web Frameworks: ArgoCD, Gitlab CI and custom operators
    Jack Henschel (CERN), Konstantinos Samaras-Tsakiris (CERN)
    27/04/2022, 11:05

    CERN's Web Frameworks are supported by a set of OpenShift clusters with shared components. We'd like to share how we use GitOps to manage their configuration, relying on ArgoCD, Helm charts and Gitlab CI. We'd also like to discuss how we can improve our current approach by relying more on ArgoCD, and upcoming solutions for secrets management.

    The multiple supported versions of the CERN...

  7. 3. The way of the force: GitOps on JEEDY
    Antonio Nappi (CERN), Ioannis Panagiotidis (Ministere des affaires etrangeres et europeennes (FR))
    27/04/2022, 11:30

    In this session you will learn how JEEDY team, build its internal infrastructure profiting of ArgoCD and git.
    In particular we will show how we managed:

    1. monitoring infrastructure for both us and users
    2. submission of user cronjobs

    The session will go through advantages, pitfalls of the GitOps approach that we faced during our development.

  8. 9. Shhh... It's a Secret!
    Ricardo Rocha (CERN)
    27/04/2022, 11:55

    There are many, many options to handle secrets in Kubernetes deployments, and even more when considering handling sensitive data in GitOps setups.

    In this short presentation we present the differences between handling (encrypted) data in Git, secrets inside the clusters, and the different tools available to simplify these tasks.
