Remove a MSR replica from a cluster


docker run -it --rm mirantis/dtr \
    remove [command options]


This command gracefully scales down your MSR cluster by removing exactly one replica. All other replicas must be healthy and will remain healthy after this operation.


Option Environment variable Description
--debug $DEBUG Enable debug mode for additional logs.
--existing-replica-id $DTR_REPLICA_ID The ID of an existing MSR replica. To add, remove or modify MSR, you must connect to an existing healthy replica’s database.
--help-extended $DTR_EXTENDED_HELP Display extended help text for a given command.
--replica-id $DTR_REMOVE_REPLICA_ID DEPRECATED Alias for --replica-ids
--replica-ids $DTR_REMOVE_REPLICA_IDS A comma separated list of IDs of replicas to remove from the cluster.
--ucp-ca $UCP_CA Use a PEM-encoded TLS CA certificate for MKE. Download the MKE TLS CA certificate from https://<mke-url>/ca, and use --ucp-ca "$(cat ca.pem)".
--ucp-insecure-tls $UCP_INSECURE_TLS Disable TLS verification for MKE. The installation uses TLS but always trusts the TLS certificate used by MKE, which can lead to MITM (man-in-the-middle) attacks. For production deployments, use --ucp-ca "$(cat ca.pem)" instead.
--ucp-password $UCP_PASSWORD The MKE administrator password.
--ucp-url $UCP_URL The MKE URL including domain and port.
--ucp-username $UCP_USERNAME The MKE administrator username.
