Korifi : API Cloud Foundry V3 expérimentale dans Kubernetes …

#kubernetes #docker #cloudfoundry #devops

Cloud Foundry est une plateforme cloud open-source en tant que service (PaaS) sur laquelle les développeurs peuvent créer, déployer, exécuter et mettre à l’échelle des applications. Pour plus d’informations sur ce qu’est Cloud Foundry et sur la manière dont elle peut aider les développeurs à créer des applications natives du nuage et les opérateurs de plate-forme à gérer ces applications à grande échelle.

Cloud Foundry Components

J’avais d’ailleurs écrit plusieurs articles à ce sujet précedemment :

Le projet Cloud Foundry For Kubernetes ( cf-for-k8s ) a prouvé l’efficacité du modèle Cloud Foundry sur Kubernetes selon ses concepteurs :

GitHub - cloudfoundry/cf-for-k8s: The open source deployment manifest for Cloud Foundry on Kubernetes

En effet, Cloud Foundry For Kubernetes ( cf-for-k8s ) associe la populaire API de développement CF à Kubernetes, Istio et d’autres technologies Open source. Le projet vise à améliorer la productivité des développeurs pour les organisations utilisant Kubernetes. cf-for-k8s peut être installé sur n’importe quel environnement en quelques minutes.


https://blogs.sap.com/2021/01/15/back-to-the-future-cloud-foundry-on-kubernetes/

À la suite de la mise à jour 23/08/21, ce projet a été déprécié pour concentrer les efforts sur Korifi :

GitHub - cloudfoundry/korifi: Cloud Foundry on Kubernetes

Korifi fournit une plateforme d’application native de Kubernetes en réimplémentant les API de base de Cloud Foundry et en les soutenant par un ensemble de ressources et de contrôleurs personnalisés de Kubernetes.

================================================================================

To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:

    dockerd-rootless-setuptool.sh install

Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.

To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker.com/go/daemon-access/

WARNING: Access to the remote API on a privileged Docker daemon is equivalent
         to root access on the host. Refer to the 'Docker daemon attack surface'
         documentation for details: https://docs.docker.com/go/attack-surface/

Quick Start

ubuntu@korifi:~$ wget -c https://github.com/kubernetes-sigs/kind/releases/download/v0.16.0/kind-linux-amd64 && chmod +x kind-linux-amd64 && sudo mv kind-linux-amd64 /usr/local/bin/kind
ubuntu@korifi:~$ kind

kind creates and manages local Kubernetes clusters using Docker container 'nodes'

Usage:
  kind [command]

Available Commands:
  build Build one of [node-image]
  completion Output shell completion code for the specified shell (bash, zsh or fish)
  create Creates one of [cluster]
  delete Deletes one of [cluster]
  export Exports one of [kubeconfig, logs]
  get Gets one of [clusters, nodes, kubeconfig]
  help Help about any command
  load Loads images into nodes
  version Prints the kind CLI version

Flags:
  -h, --help help for kind
      --loglevel string DEPRECATED: see -v instead
  -q, --quiet silence all stderr output
  -v, --verbosity int32 info log verbosity, higher value produces more output
      --version version for kind

Use "kind [command] --help" for more information about a command.

Set kubectl context to "kind-kind"
You can now use your cluster with:
