# Setting default Pod options
|
|
|
|
It is possible to configure default Pod options under the `defaultPodOptions` key. These options will be applied to all Pods specified in the chart values.
|
|
|
|
To see which fields can be configured, please take a look at the Chart values schema specific to your Common library version. The latest version can be found here: https://github.com/bjw-s-labs/helm-charts/blob/main/charts/library/common/schemas/pod.json
|
|
|
|
## Default value strategies
|
|
|
|
### Overwrite
|
|
|
|
The default strategy for configuring default Pod options is `overwrite`. This means that if a controller has an entry for a default Pod option it will be overwritten entirely by the Pod-specific configuration.
|
|
|
|
This behavior can be set explicitly by setting `defaultPodOptionsStrategy` to `overwrite`.
|
|
|
|
An (abbreviated) example of the `overwrite` strategy:
|
|
|
|
```yaml
|
|
defaultPodOptions:
|
|
resources:
|
|
requests:
|
|
memory: 1Gi
|
|
cpu: 150m
|
|
|
|
controllers:
|
|
main:
|
|
pod:
|
|
resources:
|
|
requests:
|
|
cpu: 100m
|
|
|
|
containers:
|
|
main:
|
|
...
|
|
```
|
|
|
|
The expected `resources` field on the `main` Deployment is expected to look like this:
|
|
|
|
```yaml
|
|
resources:
|
|
requests:
|
|
cpu: 100m
|
|
```
|
|
|
|
### Merge
|
|
|
|
An alternative strategy for configuring default Pod options is `merge`. This means that if a Pod has an entry for a default Pod option it will be merged with the Pod-specific configuration.
|
|
|
|
This behavior can be set explicitly by setting `defaultPodOptionsStrategy` to `merge`.
|
|
|
|
An (abbreviated) example of the `merge` strategy:
|
|
|
|
```yaml
|
|
defaultPodOptionsStrategy: merge
|
|
defaultPodOptions:
|
|
resources:
|
|
requests:
|
|
memory: 1Gi
|
|
cpu: 150m
|
|
|
|
controllers:
|
|
main:
|
|
pod:
|
|
resources:
|
|
requests:
|
|
cpu: 100m
|
|
|
|
containers:
|
|
main:
|
|
...
|
|
```
|
|
|
|
The expected `resources` field on the `main` Deployment is expected to look like this:
|
|
|
|
```yaml
|
|
resources:
|
|
requests:
|
|
memory: 1Gi
|
|
cpu: 100m
|
|
```
