12. • stable identity • durable storage • ordered startup/shutdown • backups and restores • upgrades • failover • safe day-2 operations Why this talk? Kubernetes is excellent at keeping containers running. Databases need more: The operator turns database runbooks into Kubernetes reconciliation. Copyright @ 2026 MariaDB Foundation. 12
13. Agenda 1. The Kubernetes primitives MariaDB depends on 2. What the MariaDB Operator adds 3. Installing the operator 4. Creating a first MariaDB instance 5. Databases, users, grants and app connections 6. Backups, restore and high availability 7. Practical tips for production Copyright @ 2026 MariaDB Foundation. 13

16. First principle Do not start with "How do I run a container?" Start with "How do I operate the database?" Database operations include provisioning, configuration, access, lifecycle, backups, restore, failover, observability and upgrades. Copyright @ 2026 MariaDB Foundation. 14
17. First principle Do not start with "How do I run a container?" Start with "How do I operate the database?" Database operations include provisioning, configuration, access, lifecycle, backups, restore, failover, observability and upgrades. Database provisioning is the process of setting up, and preparing a database to be used by applications or users. It encompasses installing the necessary database software, defining the schema, allocating storage, applying security settings, and ensuring it is ready for deployment. It often includes adding data to the database too (from a backup). Copyright @ 2026 MariaDB Foundation. 14
18. • Pod: runs MariaDB Server containers • Service: stable network endpoint • Secret: credentials • ConfigMap: configuration • PersistentVolumeClaim: storage request • StatefulSet: stable identity + ordered lifecycle • CustomResourceDefinition: new Kubernetes API types • Controller / Operator: reconciliation loop Kubernetes objects you will meet Copyright @ 2026 MariaDB Foundation. 15
19. Why StatefulSet matters? StatefulSet gives stateful workloads: • predictable Pod names and DNS names • stable persistent storage per Pod • ordered graceful deployment and rolling updates This is a major building block for databases. Copyright @ 2026 MariaDB Foundation. 16
20. Why StatefulSet matters? StatefulSet gives stateful workloads: • predictable Pod names and DNS names • stable persistent storage per Pod • ordered graceful deployment and rolling updates This is a major building block for databases. But StatefulSet is not a DBA. Copyright @ 2026 MariaDB Foundation. 16
21. Why StatefulSet matters? StatefulSet gives stateful workloads: • predictable Pod names and DNS names • stable persistent storage per Pod • ordered graceful deployment and rolling updates This is a major building block for databases. But StatefulSet is not a DBA. Copyright @ 2026 MariaDB Foundation. StatefulSets are essential for applications where each instance needs to remember "who it is" and "where its data is". Comparison: Deployment vs. StatefulSet +--------------+--------------------------------+-----------------------------+ | Feature | Deployment | StatefulSet | +--------------+--------------------------------+-----------------------------+ | Pod Identity | Identical/Interchangeable | Unique/Sticky | | Naming | Random suffix (e.g., web-ab12) | Ordinal index (e.g., web-0) | | Storage | Shared or ephemeral | Dedicated per Pod | | Startup | Order Parallel (any order) | Sequential (ordered) | | Updates | Rolling update | Ordered rolling update | +--------------+--------------------------------+-----------------------------+ 16
22. StatefulSet and MariaDB? Copyright @ 2026 MariaDB Foundation. 17
23. StatefulSet gives you • identity • storage binding • ordered lifecycle • restart behavior StatefulSet is necessary, not sufficient Copyright @ 2026 MariaDB Foundation. 18

26. • MariaDB • Database • User • Grant • Connection • SqlJob • Backup / Restore • PhysicalBackup / PITR-related resources • MaxScale* MariaDB What is mariadb-operator? mariadb-operator is an open source Kubernetes operator to run and operate MariaDB Server in a cloud-native way. It extends the Kubernetes API with MariaDB-specific resources such as: Copyright @ 2026 MariaDB Foundation. 20
27. mariadb-operator and Kubernetes Copyright @ 2026 MariaDB Foundation. 21
28. • Day-1 is the deployment and initial setup phase (building the database) ◦ provisioning ◦ configuration & migration ◦ schema creation • Day-2 refers to the sustained post- deployment operations phase (maintaining and running it) ◦ monitoring & alerting ◦ maintenance (backups, upgrades, ...) ◦ scaling Reminder Copyright @ 2026 MariaDB Foundation. 22
29. Operator pattern in on slide Desired state Actual state ------------- ------------ MariaDB YAML ---> operator ---> StatefulSet Database YAML ---> reconcile --> SQL database User YAML ---> reconcile --> SQL user Grant YAML ---> reconcile --> privileges Backup YAML ---> reconcile --> CronJob / Job The operator continuously compares desired state with actual state and acts to converge them.

55. Observability and day-2 operations Practical tips for production Copyright @ 2026 MariaDB Foundation. 41
56. Observability Watch three layers: 1. Kubernetes: Pods, PVCs, events, StatefulSets 2. Operator: custom resource status, reconciliation errors 3. MariaDB: connections, InnoDB, replication/Galera, slow queries, backups The operator supports Prometheus-operator integration through ServiceMonitor resources. Copyright @ 2026 MariaDB Foundation. 42

Never benchmark only in an empty cluster. 43
60. Resource tips For MariaDB Pods: • set memory requests and limits deliberately • avoid CPU limits unless you know why • leave headroom for buffer pool, connections and temp tables • tune probes for startup time • keep configuration in reviewed ConfigMaps or CR fields Copyright @ 2026 MariaDB Foundation. 44

OOMKilled is a database outage with a Kubernetes label. 44
62. Security tips • use Secrets integration; never commit passwords • separate app users from admin users • use least privilege grants • enable TLS where required • restrict network access with NetworkPolicies • use Pod Security Standards / restricted contexts • manage image provenance and upgrades Copyright @ 2026 MariaDB Foundation. 45

Recommended repository shape: clusters/ clusters/ prod/ prod/ mariadb-operator/ mariadb-operator/ databases/ databases/ users/ users/ grants/ grants/ backups/ backups/ apps/ apps/ my-app/ my-app/ connection-ref.yaml connection-ref.yaml Guardrails: • separate CRD/operator rollout from database resources • pin chart and image versions • use progressive environments • review destructive cleanup policies carefully GitOps tips Copyright @ 2026 MariaDB Foundation. 46
65. Upgrades: plan the chain Before upgrading: 1. read release notes 2. upgrade progressively; do not skip required intermediate versions 3. confirm CRD changes 4. check backup freshness 5. test in staging with production-like data 6. monitor reconciliation after upgrade Copyright @ 2026 MariaDB Foundation. 47

Treat operator upgrades like database platform upgrades, not just Helm chart upgrades. 47
67. Troubleshooting checklist If something goes wrong, check: kubectl get mariadbs,databases,users,grants,connections,backups kubectl get mariadbs,databases,users,grants,connections,backups kubectl describe mariadb mariadb kubectl describe mariadb mariadb kubectl get events --sort-by kubectl get events --sort-by= =.lastTimestamp .lastTimestamp kubectl logs deploy/mariadb-operator kubectl logs deploy/mariadb-operator kubectl get sts,pod,pvc,svc kubectl get sts,pod,pvc,svc kubectl describe pod mariadb-0 kubectl describe pod mariadb-0 Copyright @ 2026 MariaDB Foundation. 48
68. Troubleshooting checklist (2) Common causes: • CRDs missing or wrong version • Secret name/key mismatch • storage class problem • insufficient memory • slow startup vs probe thresholds • network policy or DNS issue Copyright @ 2026 MariaDB Foundation. 49
69. Production readiness checklist • supported Kubernetes + operator + MariaDB versions • storage class tested under failure • backups scheduled and monitored • restore tested and documented • resource sizing reviewed • security model reviewed • observability dashboards and alerts • upgrade path tested • disaster recovery owner identified Copyright @ 2026 MariaDB Foundation. 50
70. Demo Flow Running MariaDB Server on Kubernetes with the MariaDB Operator Copyright @ 2026 MariaDB Foundation. 51
71. Demo flow # 1. install operator helm install mariadb-operator-crds mariadb-operator/mariadb-operator-crds helm install mariadb-operator mariadb-operator/mariadb-operator # 2. create secret + MariaDB kubectl apply -f 01-mariadb.yaml # 3. declare DB access kubectl apply -f 02-database.yaml kubectl apply -f 03-user.yaml kubectl apply -f 04-grant.yaml kubectl apply -f 05-connection.yaml # 4. backup and restore kubectl apply -f 06-backup.yaml kubectl apply -f 07-restore.yaml Copyright @ 2026 MariaDB Foundation. 52
72. Key takeaways 1. StatefulSet gives MariaDB stable identity and storage, but not full operations. 2. The MariaDB Operator makes MariaDB operations declarative. 3. CRDs such as MariaDB, Database, User, Grant, Connection, Backup and Restore move platform work into GitOps workflows. 4. Production success depends on storage, backups, restore tests, observability and upgrade discipline. Copyright @ 2026 MariaDB Foundation. 53
