Kontena Classic FAQ

Does the Kontena Open Source Project require Kontena Cloud to operate?

No. The Kontena Open Source Project works just fine even without Kontena Cloud. However, in that case you need to set up your own OAuth2 authentication provider for your deployment and you'll miss all the features that are available only via Kontena Cloud.

How to get started with the Kontena Classic?

If you want to run Kontena Classic, we recommend that you follow the getting started guide.

What makes the Kontena Classic special?

Kontena is built to maximize developer happiness. Due to its simplicity, it does not require dedicated ops teams to administer, operate or maintain the platform. It is a container orchestration platform that just works. Since developers don't need to worry about the platform, they can focus on creating the stuff that matters.

Who is the ideal user of the Kontena Classic?

Kontena Classic works great for all types of businesses and may be used to run containerized workloads at any scale. It's best suited for organizations who require a worry-free, simple-to-use solution for running containerized workloads at their own datacenter.

If you are looking for a Kubernetes based solution, please take a look at Kontena Pharos. If you prefer a fully managed solution, we recommend Kontena Cloud instead.
