# `nomad node eligibility` command reference
|
|
|
|
The `node eligibility` command is used to toggle scheduling eligibility for a
|
|
given node. By default nodes are eligible for scheduling meaning they can
|
|
receive placements and run new allocations. Nodes that have their scheduling
|
|
eligibility disabled are ineligible for new placements.
|
|
|
|
The [`node drain`][drain] command automatically disables eligibility. Disabling
|
|
a drain restore eligibility by default.
|
|
|
|
Disable scheduling eligibility is useful when draining a set of nodes: first
|
|
disable eligibility on each node that will be drained. Then drain each node.
|
|
If you just drain each node allocations may get rescheduled multiple times as
|
|
they get placed on nodes about to be drained.
|
|
|
|
Disabling scheduling eligibility may also be useful when investigating poorly
|
|
behaved nodes. It allows operators to investigate the current state of a node
|
|
without the risk of additional work being assigned to it.
|
|
|
|
## Usage
|
|
|
|
```plaintext
|
|
nomad node eligibility [options] <node>
|
|
```
|
|
|
|
A `-self` flag can be used to toggle eligibility of the local node. If this is
|
|
not supplied, a node ID or prefix must be provided. If there is an exact match,
|
|
the eligibility will be adjusted for that node. Otherwise, a list of matching
|
|
nodes and information will be displayed.
|
|
|
|
It is also required to pass one of `-enable` or `-disable`, depending on which
|
|
operation is desired.
|
|
|
|
If ACLs are enabled, this option requires a token with the 'node:write'
|
|
capability.
|
|
|
|
## Options
|
|
|
|
- `-enable`: Enable scheduling eligibility.
|
|
- `-disable`: Disable scheduling eligibility.
|
|
- `-self`: Set eligibility for the local node.
|
|
- `-yes`: Automatic yes to prompts.
|
|
|
|
## Examples
|
|
|
|
Enable scheduling eligibility on node with ID prefix "574545c5":
|
|
|
|
```shell-session
|
|
$ nomad node eligibility -enable 574545c5
|
|
Node "574545c5-c2d7-e352-d505-5e2cb9fe169f" scheduling eligibility set: eligible for scheduling
|
|
```
|
|
|
|
Disable scheduling eligibility on the local node:
|
|
|
|
```shell-session
|
|
$ nomad node eligibility -disable -self
|
|
Node "574545c5-c2d7-e352-d505-5e2cb9fe169f" scheduling eligibility set: ineligible for scheduling
|
|
```
