confluent2hosts(8) -- 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`
