如何从 Python 中的 Kubernetes 集群中获取已部署微服务的 Helm 图表版本

Question

I have deployed a microservice in a K8S Cluster. Below are the Helm Chart details -

CHART_NAME=eric-bss-sd-dxp-adaptation-staging, CHART_VERSION=1.0.262, NAMESPACE=anindya-ns

Now I want to write a python script which will fetch this version of the chart (ie 1.0.262)

Please help if you have worked on such requirement before or suggest the way forward

Answer 1

I can give you some steps, it may helpful.

create a service/pod/deployment..., like below

apiVersion: v1
kind: Service
metadata:
name: {{ template "fullname" . }}
labels:
    chart: "{{ .Chart.Name }}-{{ .Chart.Version }}" 

You can use.Chart.Version in any where like name, fullname, lable...,

Use kubectl command to fetch the yaml file ex:- https://github.com/kubernetes/kubernetes/issues/24873

then write your own python code read it, fetch chat version.
