Helm 3 charts for DSB applications

This repo contains multiple Helm charts used across DSB workloads. Each chart has its own README with usage and values.

Charts included:

• dsb-nginx-frontend: NGINX-based frontend container
• dsb-spring-boot: Spring Boot web/API service
• dsb-spring-boot-job: Spring Boot CronJob model
• dsb-python-function: Simple Python function/container (HTTP) service

Create a new release by committing a new version in charts/*/Chart.yaml.

Update the test snapshots

docker run --user 1001:1001 --pull always -it --rm --name unittest --volume "$(pwd)":/apps dsbacr.azurecr.io/cache/docker-io/helmunittest/helm-unittest --update-snapshot charts/*

Debug errors like error converting YAML to JSON: yaml: line X

Running the command

helm template -f example.yaml test-application [CHART_NAME] > output.yaml
