chehsunliu opened a new pull request, #22:
URL: https://github.com/apache/ozone-helm-charts/pull/22
## What changes were proposed in this pull request?
Support configuring additional pod annotations via values.yaml. This allows
users to customize annotations such as those used to control Istio sidecar
resources:
```yaml
apiVersion: apps/v1
kind: StatefulSet
spec:
template:
metadata:
annotations:
sidecar.istio.io/proxyCPU: 100m
sidecar.istio.io/proxyCPULimit: 200m
sidecar.istio.io/proxyMemory: 128Mi
sidecar.istio.io/proxyMemoryLimit: 256Mi
```
## What is the link to the Apache JIRA
https://issues.apache.org/jira/browse/HDDS-13992
## How was this patch tested?
1. Test that the rendered templates aren't changed with default values
```bash
# Before making any code change
$ helm template charts/ozone > /tmp/ozone.v0.yaml
# After this change
$ helm template charts/ozone > /tmp/ozone.v1.yaml
$ diff -u /tmp/ozone.*.yaml
# No diff
```
2. Test that templates are correct with provided annotations
```bash
$ helm template charts/ozone \
--set "datanode.podAnnotations.sidecar\\.istio\\.io/proxyCPU=100m" \
--set "datanode.podAnnotations.sidecar\\.istio\\.io/proxyCPULimit=200m" \
--set "om.podAnnotations.sidecar\\.istio\\.io/proxyCPU=110m" \
--set "om.podAnnotations.sidecar\\.istio\\.io/proxyCPULimit=210m" \
--set "s3g.podAnnotations.sidecar\\.istio\\.io/proxyCPU=120m" \
--set "s3g.podAnnotations.sidecar\\.istio\\.io/proxyCPULimit=220m" \
--set "scm.podAnnotations.sidecar\\.istio\\.io/proxyCPU=130m" \
--set "scm.podAnnotations.sidecar\\.istio\\.io/proxyCPULimit=230m" \
> /tmp/ozone.v1.yaml
$ diff -u /tmp/ozone.*.yaml
```
