  • cert-manager installed
  • kubectl with Kustomize support
  • MikroTik device
    • RouterOS v7
    • HTTPS REST API enabled (and reachable from the cluster)
    • can route cluster Pod-CIDRs (e.g. via BGP-peering)

Quick Deploy ​

sh
kubectl create namespace mikrolb-system

kubectl -n mikrolb-system create secret generic mikrolb-config \
  --from-literal=ROUTEROS_URL="https://router.example.net" \
  --from-literal=ROUTEROS_USERNAME="mikrolb" \
  --from-literal=ROUTEROS_PASSWORD="change-me" \
  --from-file=ROUTEROS_CA_CERT=./ca.crt
