Overview

caution

K3s is in beta. Use at your own risks.

The K3s provisioning process will:

  • Create a Kubernetes management cluster with K3s.
  • Create three virtual workload clusters for each default environment (development, staging & production).
  • Create a gitops Git repository from our gitops-template and store it in your selected Git provider.
  • Install Argo CD bootstrapped against your gitops repository so your repository powers the platform, and become your source of truth.
  • Install all the platform applications using GitOps (from the /registry folder in the gitops repository).
  • Apply Terraform to configure Vault (from the /terraform/vault folder in the gitops repository).
  • Configure the gitops repository to automatically run Terraform executions through Atlantis.
  • Integrate Argo Workflows with your selected Git provider.
  • Install Argo Workflows cluster workflow templates to build containers, publish Helm charts, and provide the GitOps delivery pipelines.
  • Install metaphor, a sample application that uses this automation to demonstrate app delivery.

Known Limitations

General

  • Let's encrypt is limited to 50 weekly certificates with an additional limitations of 5 per subdomains. We use Let's encrypt to automatically create certificates for your domains. In most cases, this won't be an issue, but you may reach that limit if you create, and destroy often Kubefirst clusters using the same domain during a short period. You can use the Let's Debug Toolkit to check those, but note that the result isn't always valid.
