Bitnami MariaDB alternative
Replacing bitnamilegacy/mariadb

The bitnamilegacy/mariadb image has had about 3.5 million pulls since Bitnami moved it to the legacy repository, and it receives no updates. Switching to the official mariadb image means changing environment variables and the data path. Get either wrong and the new container starts empty.

Bitnami MariaDB variables and their official equivalents

Bitnami MariaDB image to official mariadb:

SettingBitnamiOfficial image
Root passwordMARIADB_ROOT_PASSWORDMARIADB_ROOT_PASSWORD
App user and passwordMARIADB_USER / MARIADB_PASSWORDMARIADB_USER / MARIADB_PASSWORD
DatabaseMARIADB_DATABASEMARIADB_DATABASE
Data path/bitnami/mariadb/data/var/lib/mysql

What breaks when you switch

  • Core variables share names; the data path changes from /bitnami/mariadb/data to /var/lib/mysql.
  • Bitnami's replication and Galera settings do not carry over.

What happened to the Bitnami MariaDB image

For years, bitnami/mariadb on Docker Hub was one of the most common ways to deploy MariaDB on Kubernetes, usually through the Bitnami MariaDB Helm chart. On 28 August 2025 Broadcom moved every versioned Bitnami container image, including this one, to the bitnamilegacy repository, and removed the public docker.io/bitnami catalog on 29 September 2025. The free tier now offers only latest tags of a limited set of images for development.

The legacy Docker image still pulls, so existing deployments keep working. It no longer receives updates, which means every vulnerability disclosed since the move stays open in the MariaDB binary, in the base image and in every bundled dependency. Container scanners will report a growing count at every audit, and a workload that depends on a frozen public repository is one registry change away from ImagePullBackOff.

How to migrate MariaDB off Bitnami safely

  1. Find every reference to bitnami/mariadb and bitnamilegacy/mariadb in running workloads, Helm values files and CI pipelines, including init containers.
  2. Record the MariaDB version each deployment pins. Versions past upstream end of life are not covered by the free open source images.
  3. Take a backup and test a restore before touching a stateful workload.
  4. Mirror the replacement container images into your own registry, and scan them before you deploy.
  5. Move one replica or one environment at a time, and confirm the data path, file ownership and credentials on the new image.
  6. Remove every remaining legacy reference so nothing falls back to the archive on the next deploy.

Your options

Ask for an OSSeva drop-in image

OSSeva does not ship a MariaDB image yet. Tell us you need one; we prioritise new images by the number of teams asking.

Official mariadb image

Free and maintained for current versions. Apply the mapping above and move the volume.

mariadb-operator

An open source Kubernetes operator for MariaDB, including Galera clusters.

Bitnami Secure Images

Broadcom's paid catalog keeps the Bitnami layout for supported versions, sold within TrueSource.

Repoint the Bitnami MariaDB Helm chart

# values-override.yaml
image:
  registry: registry.example.com   # your mirror of the replacement image
  repository: mariadb
  tag: "<pinned version>"
global:
  security:
    allowInsecureImages: true      # recent Bitnami charts reject non-Bitnami images without this

This works only with an image that keeps Bitnami's layout. With the official image, rewrite the chart or move to an operator. See replacing bitnamilegacy images for the full inventory and rollout steps.

Frequently asked questions

What is the best alternative to the Bitnami MariaDB image?

The official mariadb image, or mariadb-operator on Kubernetes. Map the Bitnami variables and data path first, as shown on this page.

Is bitnamilegacy/mariadb still getting security updates?

No. Bitnami moved versioned images to the bitnamilegacy repository on 28 August 2025 and describes it as receiving no further updates. It had about 3.5 million pulls by September 2026.

Can I keep using the Bitnami MariaDB Helm chart?

Yes, with a maintained image that keeps Bitnami's layout. Set image.registry and image.repository in your values file, and set global.security.allowInsecureImages to true, because recent Bitnami charts refuse non-Bitnami images otherwise.

Is Bitnami no longer free?

Not for production. Since 28 August 2025, versioned Bitnami images live in the bitnamilegacy repository with no updates, and the free tier offers latest tags of a limited set of images for development. Maintained, versioned images are sold as Bitnami Secure Images, which Broadcom prices by quote.

Where does the Bitnami MariaDB image store data?

Under /bitnami/mariadb/data. The official image uses /var/lib/mysql, so the volume mount must change when you switch images.
