nodeattrib(8) -- List or change confluent nodes attributes
|
|
=========================================================
|
|
|
|
## SYNOPSIS
|
|
|
|
`nodeattrib [-b] <noderange> [all|<nodeattribute>...]`
|
|
`nodeattrib <noderange> [<nodeattribute1=value1> <nodeattribute2=value2> ...]`
|
|
`nodeattrib -c <noderange> <nodeattribute1> <nodeattribute2> ...`
|
|
`nodeattrib -e <noderange> <nodeattribute1> <nodeattribute2> ...`
|
|
|
|
## DESCRIPTION
|
|
|
|
**nodeattrib** manages the attributes of confluent nodes. In
|
|
the simplest form, it simply takes the given noderange(5) and lists the
|
|
matching nodes, one line at a time.
|
|
|
|
If a list of node attribute names are given, the value of those are also
|
|
displayed. If `-b` is specified, it will also display information on
|
|
how inherited and expression based attributes are defined. Attributes can be
|
|
straightforward values, or an expression as documented in nodeattribexpressions(5).
|
|
For a full list of attributes, run `nodeattrib <node> all` against a node.
|
|
If `-c` is specified, this will set the nodeattribute to a null value.
|
|
This is different from setting the value to an empty string.
|
|
|
|
For the `groups` attribute, it is possible to add a group by doing
|
|
`groups,=<newgroup>` and to remove by doing `groups^=<oldgroup>`
|
|
|
|
Note that `nodeattrib <group>` will likely not provide the expected behavior.
|
|
See nodegroupattrib(8) command on how to manage attributes on a group level.
|
|
|
|
## OPTIONS
|
|
|
|
* `-b`, `--blame`:
|
|
Annotate inherited and expression based attributes to show their base value.
|
|
* `-c`, `--clear`:
|
|
Clear specified nodeattributes
|
|
* `-e`, `--environment`:
|
|
Set specified attributes based on exported environment variable of matching name. Environment variable names may be lower case or all upper case. Replace . with _ as needed (e.g. info.note may be specified as either $info_note or $INFO_NOTE
|
|
|
|
## EXAMPLES
|
|
* Listing matching nodes of a simple noderange:
|
|
`# nodeattrib n1-n2`
|
|
`n1: console.method: ipmi`
|
|
`n1: hardwaremanagement.manager: 172.30.3.1`
|
|
`n2: console.method: ipmi`
|
|
`n2: hardwaremanagement.manager: 172.30.3.2`
|
|
|
|
* Getting an attribute of nodes matching a noderange:
|
|
`# nodeattrib n1,n2 hardwaremanagement.manager`
|
|
`n1: hardwaremanagement.manager: 172.30.3.1`
|
|
`n2: hardwaremanagement.manager: 172.30.3.2`
|
|
|
|
* Getting a group of attributes while determining what group defines them:
|
|
`# nodeattrib n1,n2 hardwaremanagement --blame`
|
|
`n1: hardwaremanagement.manager: 172.30.3.1`
|
|
`n1: hardwaremanagement.method: ipmi (inherited from group everything)`
|
|
`n1: hardwaremanagement.switch: r8e1`
|
|
`n1: hardwaremanagement.switchport: 14`
|
|
`n2: hardwaremanagement.manager: 172.30.3.2`
|
|
`n2: hardwaremanagement.method: ipmi (inherited from group everything)`
|
|
`n2: hardwaremanagement.switch: r8e1`
|
|
`n2: hardwaremanagement.switchport: 2`
|
|
|
|
* Listing matching nodes of a simple noderange that are set:
|
|
`# nodeattrib n1-n2 current`
|
|
`n1: console.method: ipmi`
|
|
`n1: hardwaremanagement.manager: 172.30.3.1`
|
|
`n2: console.method: ipmi`
|
|
`n2: hardwaremanagement.manager: 172.30.3.2`
|
|
|
|
* Change attribute on nodes of a simple noderange:
|
|
`# nodeattrib n1-n2 console.method=serial`
|
|
`n1: console.method: serial`
|
|
`n1: hardwaremanagement.manager: 172.30.3.1`
|
|
`n2: console.method: serial`
|
|
`n2: hardwaremanagement.manager: 172.30.3.2`
|
|
|
|
* Clear attribute on nodes of a simple noderange, if you want to retain the variable set the attribute to "":
|
|
`# nodeattrib n1-n2 -c console.method`
|
|
`# nodeattrib n1-n2 console.method`
|
|
`n1: console.method: `
|
|
`n2: console.method: `
|
|
|
