Bootstrap a Caliopen instance on a Kubernetes cluster on Gandi IaaS platform

Requirements:

• Libcloud with Gandi module
• Ansible with Gandi modules and dynamic inventory script
• Gandi IaaS account and its api key

Bootstraping the cluster:

1. Configure the VM deployment modifying the file vm_vars/settings.yaml
2. Set your Gandi IaaS API key modifying the file vm_vars/credentials.yaml
3. Create the VMs
   • ansible-playbook vm-deploy.yml
4. Configure your deployment modifying the file group_vars/all
5. Modify the Caliopen configuration found in roles/caliopen/templates/configs
6. Cluster certificates can be found in roles/caliopen/templates/configs and roles/lb/files
7. Setup your k8s cluster and deploy Caliopen on it
   • ansible-playbook -i PATH_TO_DYNAMIC_INVENTORY_SCRIPT deployment.yml

Options:

Cluster visibility

The current configuration deploys the machines in the cluster (including the master node) exclusively with private ips. External access goes through an extra machine, external to the cluster, running HAProxy. Its configuration can be found in roles/lb/templates/haproxy.cfg.j2.

SMTP Server

For now the cluster must be deployed with an external Postfix server.

Storage

The cluster must be deployed with external Cassandra, Minio and Elasticsearch clusters.

Limitations:

• The cluster deployed has a single master node

• High availability of the load balancer is not handled
