- Introduced `k8s-mssql-configmap-example.yaml` and `k8s-mssql-secret-example.yaml` to provide templates for non-sensitive and sensitive configurations, respectively. - Updated `README.md` and `k8s-statefulset-test.yaml` to reference the new example files. - Created `k8s-statefulset-with-sidecar.yaml` for deploying MSSQL with a backup sidecar, enhancing the backup functionality.

# Notes:
|
|
#
|
|
# 1. ConfigMap vs Secret:
|
|
# - ConfigMap: Non-sensitive configuration (endpoints, names, schedules)
|
|
# - Secret: Sensitive data (passwords, access keys)
|
|
#
|
|
# 2. To update ConfigMap after deployment:
|
|
# kubectl apply -f k8s-mssql-configmap.yaml
|
|
# kubectl rollout restart statefulset/mssql
|
|
#
|
|
# 3. To view the ConfigMap:
|
|
# kubectl get configmap mssql-config -o yaml
|
|
#
|
|
# 4. DATABASE_HOST behavior:
|
|
# - In sidecar pattern: Set to "localhost" (overridden in StatefulSet)
|
|
# - In CronJob pattern: Use service name like "mssql-service"
|
|
# The ConfigMap default is for CronJob; sidecar overrides it in the pod spec.
|
|
#
|
|
# 5. Alternative: Create from command line:
|
|
# kubectl create configmap mssql-config \
|
|
# --from-literal=DATABASE_SERVER='mssql' \
|
|
# --from-literal=DATABASE_HOST='mssql-service' \
|
|
# --from-literal=DATABASE_NAME='MyDatabase' \
|
|
# --from-literal=DATABASE_PORT='1433' \
|
|
# --from-literal=MSSQL_DATA_DIR='/var/opt/mssql/data' \
|
|
# --from-literal=SCHEDULE='0 2 * * *' \
|
|
# --from-literal=BACKUP_KEEP_DAYS='7' \
|
|
# --from-literal=S3_BUCKET='my-backups' \
|
|
# --from-literal=S3_PREFIX='mssql-backups' \
|
|
# --from-literal=S3_REGION='us-east-1' \
|
|
# --from-literal=S3_ENDPOINT='https://s3.example.com' \
|
|
# --from-literal=S3_S3V4='yes'
