Who is using Cilium?

Sharing experiences and learning from other users is essential. We are frequently asked who is using a particular feature of Cilium so people can get in contact with other users to share experiences and best practices. People also often want to know if product/platform X has integrated Cilium. While the Cilium Slack community allows users to get in touch, it can be challenging to find this information quickly.

The following is a directory of adopters to help identify users of individual features. The users themselves directly maintain the list.

Adding yourself as a user

If you are using Cilium or it is integrated into your product, service, or platform, please consider adding yourself as a user with a quick description of your use case by opening a pull request to this file and adding a section describing your usage of Cilium. If you are open to others contacting you about your use of Cilium on Slack, add your Slack nickname as well.

N: Name of user (company)
D: Description
U: Usage of features
L: Link with further information (optional)
Q: Contacts available for questions (optional)

Example entry:

* N: Cilium Example User Inc.
  D: Cilium Example User Inc. is using Cilium for scientific purposes
  U: ENI networking, DNS policies, ClusterMesh
  Q: @slacknick1, @slacknick2

Requirements to be listed

  • You must represent the user listed. Do NOT add entries on behalf of other users.
  • There is no minimum deployment size but we request to list permanent production deployments only, i.e., no demo or trial deployments. Commercial use is not required. A well-done home lab setup can be equally interesting as a large-scale commercial deployment.
