# Deploy Multi-Master cloudformation 1. Replace all of the variables of file cf_parameters.conf with the proper values. For example: ```conf export DOMAIN_NAME="ov-multimaster-2.k8s.codeurjc.es" export OPENVIDU_LICENSE="valid-license" export KIBANA_HOST="https://search-ov-elasticsearch-3gxumtiwg67qp6jplw7rkjshrm.eu-west-1.es.amazonaws.com:443/_plugin/kibana/" export ELASTICSEARCH_HOST="https://search-ov-elasticsearch-3gxumtiwg67qp6jplw7rkjshrm.eu-west-1.es.amazonaws.com:443" export SSH_KEY_NAME="kms-aws-share-key" export VPC="vpc-6bf6a10f" export SUBNETS="subnet-599ebd3d,subnet-f1ed81a9" export LOAD_BALANCER_CERTIFICATE="arn:aws:acm:eu-west-1:849201093595:certificate/01d51580-d8fc-45b0-9c72-e7666ba890d9" export MASTER_NODE_INSTANCE_TYPE="t2.large" export MEDIA_NODE_INSTANCE_TYPE="t2.large" ``` 2. Run script `./deploy_cf.sh` 3. Update Route 53 to link the domain name to the Load Balancer. At [https://console.aws.amazon.com/route53/v2/hostedzones#ListRecordSets/](https://console.aws.amazon.com/route53/v2/hostedzones#ListRecordSets/) edit record of subdomain `ov-multimaster-2.k8s.codeurjc.es`, routing traffic to the Load Balancer (dualstack.ov-pro-multimaster-VAR1-lb-VAR2.eu-west-1.elb.amazonaws.com).
