[Enhancement]: expose podSecurityContext and containerSecurityContext as etcd helm chart values

[uniquejava]

Is there an existing issue for this?

• I have searched the existing issues

What would you like to be added?

Milvus helm chart cannot be deployed to OpenShift, due to etcd securityContext constraint, see:

1. This issue: [bitnami/etcd] unable to validate against any security context constraint bitnami/charts#12215
2. This discussion: k8s集群部署采用最低配置时出现问题 #30599

I searched original helm chart in etcd, here are they:

1. https://github.com/bitnami/charts/blob/main/bitnami/etcd/values.yaml#L311
2. https://github.com/bitnami/charts/blob/main/bitnami/etcd/values.yaml#L330

Expect milvus helm chart to expose these two enabled parameter, then we can install milvus on OpenShift.

Something like this:

helm install my-milvus milvus/milvus \
--set etcd.podSecurityContext.enabled=false \
--set etcd.containerSecurityContext.enabled=false

Why is this needed?

Etcd cannot be installed on Openshift given current milvus default setting, and no parameter can be set to disable securityContext when install helm chart.

Anything else?
