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
nodeSelectorfield 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=value2andkey2=value2labels.
