FAQ

What is the difference between KubeVela and project-X ?

Refer to the comparison details.

Do yo support Crossplane? What's the difference between terraform and Corssplane in KubeVela?

KubeVela natively support Crossplane as they're already CRDs, while terraform was not a CRD controller, so the KubeVela community author a terraform controller for integration. You can choose any of them as you wish.

What's the relationship between KubeVela and OAM? What will KubeVela mainly focus?

  • OAM(Open Application Model) is the model behind KubeVela, it provides a platform-agnostic application model including the best practices and methodology for different vendors to follow. The evolution of the model depends primarily on the practices of KubeVela currently.
  • KubeVela is the control plane running on Kubernetes, it works as a CRD controller and brings OAM model into your Cloud Native PaaS along with lots of addon capabilities. KubeVela will mainly focus on application delivery, the goal is to make deploying and operating applications across today's hybrid, multi-cloud environments easier, faster and more reliable.

Common Issues

The document website is very slow to access.

You can use https://kubevela.net/ as a faster alternative.

You have reached rate limit for Docker Image Registry

By default, the community use images from docker registry for installation. You can use the following alternatives:

  1. You can use github container registry, check the list of official images for more details. There're two kinds of format:
  • Before v1.4.1, the image format is ghcr.io/<git-repo>/vela-core:<version>, e.g. "ghcr.io/kubevela/kubevela/vela-core:latest".
  • After v1.4.1, the image format has changed to ghcr.io/kubevela/<align with docker hub>, e.g. "ghcr.io/kubevela/oamdev/vela-core:latest".

  1. Alibaba Container Registry also sponsor KubeVela community, you can use acr.kubevela.net/ as prefix for the docker registry, acr has a sync for each KubeVela official images. Use it like acr.kubevela.net/oamdev/vela-core:latest.

  2. If you insist on using Docker registry, you may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit .
