how to inject secrets into Kubernetes pods via Vault Agent containers using env variables

Hello everyone, I need your help. I’m trying to perform secret injection via Vault into a Kubernetes cluster, but I’m struggling to set what I retrieve from Vault as a global variable. Here’s my deployment:

`apiVersion: apps/v1
kind: Deployment
metadata:
name: app-pyth
labels:
app: app-pyth
spec:
replicas: 2
selector:
matchLabels:
app: app-pyth
template:
metadata:
labels:
app: app-pyth
annotations:
vault.hashicorp.com/agent-inject: 'true'
vault.hashicorp.com/role: 'internal-app'
vault.hashicorp.com/agent-inject-secrets: 'internal/data/database/config'
vault.hashicorp.com/agent-inject-template-secrets: |
{{- with secret "internal/data/database/config" -}}
export USERNAME={{ .Data.data.username }}
export PASSWORD={{ .Data.data.password }}
export ROOT_PASSWORD={{ .Data.data.rootpassword }}
export DATABASE={{ .Data.data.database }}
export HOST={{ .Data.data.host }}
{{- end -}}
spec:
serviceAccountName: internal-app
containers:
- name: myapp
image: adouadi/python:latest
ports:
- containerPort: 80
command: ['/bin/bash', '-c', ]
args: ['source /vault/secrets/secrets']. `

I don’t have an entrypoint script like this: [‘source /vault/secrets/config && <entrypoint script>’] because my script is executed within my Docker image. When I go into the pod at the path /vault/secrets/secrets, I can see the variables properly retrieved from Vault.please help me
