Patch resources using the strategic merge patch standard.
|
||||
---
|
||||
|
||||
Each entry in this list should be either a relative
|
||||
file path or an inline content
|
||||
resolving to a partial or complete resource
|
||||
definition.
|
||||
|
||||
The names in these (possibly partial) resource
|
||||
files must match names already loaded via the
|
||||
`resources` field. These entries are used to
|
||||
_patch_ (modify) the known resources.
|
||||
|
||||
Small patches that do one thing are best, e.g. modify
|
||||
a memory request/limit, change an env var in a
|
||||
ConfigMap, etc. Small patches are easy to review and
|
||||
easy to mix together in overlays.
|
||||
|
||||
```yaml
|
||||
apiVersion: kustomize.config.k8s.io/v1beta1
|
||||
kind: Kustomization
|
||||
|
||||
patchesStrategicMerge:
|
||||
- service_port_8888.yaml
|
||||
- deployment_increase_replicas.yaml
|
||||
- deployment_increase_memory.yaml
|
||||
```
|
||||
|
||||
The patch content can be a inline string as well.
|
||||
```yaml
|
||||
apiVersion: kustomize.config.k8s.io/v1beta1
|
||||
kind: Kustomization
|
||||
|
||||
patchesStrategicMerge:
|
||||
- |-
|
||||
apiVersion: apps/v1
|
||||
kind: Deployment
|
||||
metadata:
|
||||
name: nginx
|
||||
spec:
|
||||
template:
|
||||
spec:
|
||||
containers:
|
||||
- name: nginx
|
||||
image: nignx:latest
|
||||
```
|
||||
|
||||
Note that kustomize does not support more than one patch
|
||||
for the same object that contain a _delete_ directive. To remove
|
||||
several fields / slice elements from an object create a single
|
||||
patch that performs all the needed deletions.
