Kubernetes Cluster⚓︎

The EOEPCA Reference Implementation has been developed with Kubernetes as its deployment target. The system components have been developed, deployed and tested using a cluster at version v1.22.5.

Note

The Scripted Deployment assumes that minikube is installed, and creates a minikube cluster under the profile eoepca.

Rancher Kubernetes Engine (RKE)⚓︎

The development, integration and test clusters have been established using Rancher Kubernetes Engine (RKE) at version v1.22.5.

An example of the creation of the EOEPCA Kubernetes clusters can be found on the GitHub Kubernetes Setup page. CREODIAS has been used for the development hosting infrastructure - which provides OpenStack infrastructure that is backed by Cloudferro. An example of the Terraform configurations used to automate the creation of the cloud infrastructure that underpins the RKE deployment can be found on the GitHub CREODIAS Setup page.

Local Kubernetes⚓︎

To make a full deployment of the EOEPCA Reference Implementation requires a multi-node node cluster with suitable resources. For example, the development cluster comprises:

  • 1 Master node (2 vCPU, 8 GB RAM)
  • 5 Worker nodes (4 vCPU, 16 GB RAM)
  • 1 NFS server (2 vCPU, 8 GB RAM)

Limited local deployment can be made using a suitable local single-node kuberbetes deployment using - for example using minikube…

minikube -p eoepca start --cpus max --memory max --kubernetes-version v1.22.5
minikube profile eoepca

With such a deployment it is possible to deploy individual building-blocks for local development, or building-blocks in combination - within the constraints of the local host resources.
