NAME

confluent2hosts - Generate /etc/hosts entries for nodes

SYNOPSIS

confluent2hosts -i <ip expression> -n <name expression> <noderange>
confluent2hosts -a <noderange>

DESCRIPTION

confluent2hosts can be used to help generate /etc/hosts entries for a noderange. There are two general approaches.

It can be used ad-hoc, using -i and -n to specify the address and name portions respectively. This accepts the standard confluent expression syntax, allowing for things like 172.30.1.{n1} or {node}.{dns.domain} or {bmc}.

It can also read from the confluent db, using -a. In this mode, each net.value.attribute group is pulled together into hosts lines. ipv4_address and ipv6_address fields are associated with the corresponding hostname attributes.

EXAMPLES

Generate /etc/hosts entries ad-hoc using default name
# confluent2hosts -i 10.2.3.{n1} d9-d12
Generate /etc/hosts entries ad-hoc using alternative name
# confluent2hosts -i 10.2.3.{n1} -n "{node}-alt {node}-alt.{dns.domain}" d9-d12
Generate /etc/hosts entries using the confluent DB as a reference
# confluent2hosts -a d9-d12
