• cloudeos.yaml - YAML file for deploying the CloudEOS Daemonset
• RELEASE-NOTES.md - Release notes for this version
• leaf-switch.config - config example for BGP Peer switch

There are a few design goals with CloudEOS:

• Provide a Kubernetes native deployment model
• Allow for easy deployment of cluster nodes
• Provide an operationally consistent networking model for administrators
• Provide the benefits of EOS from a management, observability, feature, and supportability in a Kubernetes networking environment.

CloudEOS achieves these goals by the following:

• Using a daemonset to deploy CloudEOS containers on each node in the cluster
• Providing configuration options directly in the deployment YAML file
• Allowing standard EOS configuration
• Using the same binary as any other EOS based device
• Support for streaming telemetry and management through Arista CloudVision

Annotations have a higher precendence than environment variables

Environment Variables will be used if Annotations are not present

(optional) If you need to apply a chunk of static config to every pod you can also create a configmap in Kubernetes that will store and configure all CloudEOS pods with generic configuration. NOTE: These commands must be fully expanded (i.e. interface Ethernet 1, not int eth 1), and no syntax checking will occur. If there are syntax errors with the commands it may prevent the pod from starting. In this example I'm adding a few lines of static config for SSH to be remapped to port 8022 and adding an NTP server. This config will be placed on every CloudEOS pod.

apiVersion: v1
kind: ConfigMap
metadata:
  name: cloudeos-configmap
  namespace: default
data:
  cloudeos-config-data: |
    ntp-server 172.22.22.50
    management ssh
    server-port 8022

You will then need to add this configmap to your YAML specification for CloudEOS, namely as a volumeMount under cloudeos-init and a volume under the pod. These are noted in the following snippets with a comment:

Entry for the cloudeos-init container:

  initContainers:
  - image: aristanetworks/cloudeos-init:0.9
    name: cloudeos-init
    command: ["/ceos-init", "-cni=false"]
    env:
      - name: "CLOUDVISION_IP"
        value: "10.90.224.175"
    volumeMounts:
    - name: kickstart-config
      mountPath: /config/
    # Add the following:
    - name: configmap-config
      mountPath: /config/cloudeos-configmap

Entry for the volumes section:

volumes:
- name: kickstart-config
  hostPath:
    path: /opt/cni/cloudeos
# Add the following:
- name: configmap-config
  configMap:
    name: cloudeos-configmap
