9.3. Assigning builds to specific nodes
Builds can be targeted to run on specific nodes by specifying labels in the nodeSelector
field of a build configuration. The nodeSelector
value is a set of key-value pairs that are matched to Node
labels when scheduling the build pod.
The nodeSelector
value can also be controlled by cluster-wide default and override values. Defaults will only be applied if the build configuration does not define any key-value pairs for the nodeSelector
and also does not define an explicitly empty map value of nodeSelector:{}
. Override values will replace values in the build configuration on a key by key basis.
If the specified NodeSelector
cannot be matched to a node with those labels, the build still stay in the Pending
state indefinitely.
Procedure
Assign builds to run on specific nodes by assigning labels in the
nodeSelector
field of theBuildConfig
, for example:apiVersion: "v1" kind: "BuildConfig" metadata: name: "sample-build" spec: nodeSelector:1 key1: value1 key2: value2
- 1
- Builds associated with this build configuration will run only on nodes with the
key1=value2
andkey2=value2
labels.
