Why use Bitnami Secure Images?

Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise https://vmware.github.io/photon/. Why choose BSI images?

• Hardened secure images of popular open source software with Near-Zero Vulnerabilities
• Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores
• Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM)
• Software supply chain provenance attestation through in-toto
• First class support for the internet’s favorite Helm charts

Each image comes with valuable security metadata. You can view the metadata in our public catalog here. Note: Some data is only available with commercial subscriptions to BSI.

How to deploy MinIO(R) in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the https://github.com/bitnami/charts/tree/master/bitnami/minio.

Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Supported tags and respective Dockerfile links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

You can see the equivalence between the different tags by taking a look at the tags-info.yaml file present in the branch folder, i.e bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml.

Get this image

The recommended way to get the Bitnami MinIO(R) Docker Image is to pull the prebuilt image from the https://hub.docker.com/r/bitnami/minio.

console
docker pull bitnami/minio:latest

To use a specific version, you can pull a versioned tag. You can view the https://hub.docker.com/r/bitnami/minio/tags/ in the Docker Hub Registry.

console
docker pull bitnami/minio:[TAG]

If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the docker build command. Remember to replace the APP, VERSION and OPERATING-SYSTEM path placeholders in the example command below with the correct values.

console
git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .

Persisting your database

If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a directory at the /bitnami/minio/data path.

console
docker run --name minio \
    --publish 9000:9000 \
    --publish 9001:9001 \
    --volume /path/to/minio-persistence:/bitnami/minio/data \
    bitnami/minio:latest

or by modifying the https://github.com/bitnami/containers/blob/main/bitnami/minio/docker-compose.yml file present in this repository:

yaml
services:
  minio:
  ...
    volumes:
      - /path/to/minio-persistence:/bitnami/minio/data
  ...

You can also mount a volume to a custom path inside the container, provided that you run the container using the MINIO_DATA_DIR environment variable.

console
docker run --name minio \
    --publish 9000:9000 \
    --publish 9001:9001 \
    --volume /path/to/minio-persistence:/custom/path/within/container \
    --env MINIO_DATA_DIR=/custom/path/within/container \
    bitnami/minio:latest

or by modifying the https://github.com/bitnami/containers/blob/main/bitnami/minio/docker-compose.yml file present in this repository:

yaml
services:
  minio:
  ...
    volumes:
      - /path/to/minio-persistence:/custom/path/within/container
  ...
    environment:
      - MINIO_DATA_DIR=/custom/path/within/container
  ...

NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID 1001.

Connecting to other containers

Using Docker container networking, a MinIO(R) server running inside a container can easily be accessed by your application containers.

Containers attached to the same network can communicate with each other using the container name as the hostname.

Using the Command Line

In this example, we will create a https://github.com/bitnami/containers/blob/main/bitnami/minio-client container that will connect to the server container that is running on the same docker network as the client.

Step 1: Create a network

console
docker network create app-tier --driver bridge

Step 2: Launch the MinIO(R) server container

Use the --network app-tier argument to the docker run command to attach the MinIO(R) container to the app-tier network.

console
docker run -d --name minio-server \
    --env MINIO_ROOT_USER="minio-root-user" \
    --env MINIO_ROOT_PASSWORD="minio-root-password" \
    --network app-tier \
    bitnami/minio:latest

Step 3: Launch your MinIO(R) Client container

Finally we create a new container instance to launch the MinIO(R) client and connect to the server created in the previous step. In this example, we create a new bucket in the MinIO(R) storage server:

console
docker run -it --rm --name minio-client \
    --env MINIO_SERVER_HOST="minio-server" \
    --env MINIO_SERVER_ACCESS_KEY="minio-access-key" \
    --env MINIO_SERVER_SECRET_KEY="minio-secret-key" \
    --network app-tier \
    bitnami/minio-client \
    mb minio/my-bucket

Using a Docker Compose file

When not specified, Docker Compose automatically sets up a new network and attaches all deployed services to that network. However, we will explicitly define a new bridge network named app-tier. In this example we assume that you want to connect to the MinIO(R) server from your own custom application image which is identified in the following snippet by the service name myapp.

yaml
version: '2'

networks:
  app-tier:
    driver: bridge

services:
  minio:
    image: bitnami/minio:latest
    ports:
      - 9000:9000
      - 9001:9001
    environment:
      - MINIO_ROOT_USER=minio-root-user
      - MINIO_ROOT_PASSWORD=minio-root-password
    networks:
      - app-tier
  myapp:
    image: YOUR_APPLICATION_IMAGE
    networks:
      - app-tier
    environment:
      - MINIO_SERVER_ACCESS_KEY=minio-access-key
      - MINIO_SERVER_SECRET_KEY=minio-secret-key

IMPORTANT:

1. Please update the YOUR_APPLICATION_IMAGE_ placeholder in the above snippet with your application image
2. In your application container, use the hostname minio to connect to the MinIO(R) server. Use the environment variables MINIO_SERVER_ACCESS_KEY and MINIO_SERVER_SECRET_KEY to configure the credentials to access the MinIO(R) server.
3. Make sure that the environment variables MINIO_ROOT_PASSWORD and MINIO_SERVER_SECRET_KEY meet the 8 character minimum length requirement enforced by MinIO(R).

Launch the containers using:

console
docker-compose up -d

Configuration

Environment variables

Customizable environment variables

Read-only environment variables

Additionally, MinIO can be configured via environment variables as detailed at MinIO(R) documentation.

A MinIO(R) Client (mc) is also shipped on this image that can be used to perform administrative tasks as described at the MinIO(R) Client documentation. In the example below, the client is used to obtain the server info:

console
docker run --name minio -d bitnami/minio:latest
docker exec minio mc admin info local

or using Docker Compose:

console
curl -sSL https://raw.githubusercontent.com/bitnami/containers/main/bitnami/minio/docker-compose.yml > docker-compose.yml
docker-compose up -d
docker-compose exec minio mc admin info local

Creating default buckets

You can create a series of buckets in the MinIO(R) server during the initialization of the container by setting the environment variable MINIO_DEFAULT_BUCKETS as shown below (policy is optional):

console
docker run --name minio \
    --publish 9000:9000 \
    --publish 9001:9001 \
    --env MINIO_DEFAULT_BUCKETS='my-first-bucket:policy,my-second-bucket' \
    bitnami/minio:latest

or by modifying the https://github.com/bitnami/containers/blob/main/bitnami/minio/docker-compose.yml file present in this repository:

yaml
services:
  minio:
  ...
    environment:
      - MINIO_DEFAULT_BUCKETS=my-first-bucket:policy,my-second-bucket
  ...

Securing access to MinIO(R) server with TLS

You can secure the access to MinIO(R) server with TLS as detailed at MinIO(R) documentation.

This image expects the variable MINIO_SCHEME set to https and certificates to be mounted at the /certs directory. You can put your key and certificate files on a local directory and mount it in the container as shown below:

console
docker run --name minio \
    --publish 9000:9000 \
    --publish 9001:9001 \
    --volume /path/to/certs:/certs \
    --env MINIO_SCHEME=https
    bitnami/minio:latest

or by modifying the https://github.com/bitnami/containers/blob/main/bitnami/minio/docker-compose.yml file present in this repository:

yaml
services:
  minio:
  ...
    environment:
    ...
      - MINIO_SCHEME=https
    ...
    volumes:
      - /path/to/certs:/certs
  ...

Setting up MinIO(R) in Distributed Mode

You can configure MinIO(R) in Distributed Mode to setup a highly-available storage system. To do so, the environment variables below must be set on each node:

• MINIO_DISTRIBUTED_MODE_ENABLED: Set it to 'yes' to enable Distributed Mode.
• MINIO_DISTRIBUTED_NODES: List of MinIO(R) nodes hosts. Available separators are ' ', ',' and ';'.
• MINIO_ROOT_USER: MinIO(R) server root user. Must be common on every node.
• MINIO_ROOT_PASSWORD: MinIO(R) server root password. Must be common on every node.

You can use the Docker Compose below to create an 4-node distributed MinIO(R) setup:

yaml
version: '2'

services:
  minio1:
    image: bitnami/minio:latest
    environment:
      - MINIO_ROOT_USER=minio-root-user
      - MINIO_ROOT_PASSWORD=minio-root-password
      - MINIO_DISTRIBUTED_MODE_ENABLED=yes
      - MINIO_DISTRIBUTED_NODES=minio1,minio2,minio3,minio4
      - MINIO_SKIP_CLIENT=yes
  minio2:
    image: bitnami/minio:latest
    environment:
      - MINIO_ROOT_USER=minio-root-user
      - MINIO_ROOT_PASSWORD=minio-root-password
      - MINIO_DISTRIBUTED_MODE_ENABLED=yes
      - MINIO_DISTRIBUTED_NODES=minio1,minio2,minio3,minio4
      - MINIO_SKIP_CLIENT=yes
  minio3:
    image: bitnami/minio:latest
    environment:
      - MINIO_ROOT_USER=minio-root-user
      - MINIO_ROOT_PASSWORD=minio-root-password
      - MINIO_DISTRIBUTED_MODE_ENABLED=yes
      - MINIO_DISTRIBUTED_NODES=minio1,minio2,minio3,minio4
      - MINIO_SKIP_CLIENT=yes
  minio4:
    image: bitnami/minio:latest
    environment:
      - MINIO_ROOT_USER=minio-root-user
      - MINIO_ROOT_PASSWORD=minio-root-password
      - MINIO_DISTRIBUTED_MODE_ENABLED=yes
      - MINIO_DISTRIBUTED_NODES=minio1,minio2,minio3,minio4
      - MINIO_SKIP_CLIENT=yes

MinIO(R) also supports ellipsis syntax ({1..n}) to list the MinIO(R) node hosts, where n is the number of nodes. This syntax is also valid to use multiple drives ({1..m}) on each MinIO(R) node, where n is the number of drives per node. You can use the Docker Compose below to create an 2-node distributed MinIO(R) setup with 2 drives per node:

yaml
version: '2'
services:
  minio-0:
    image: bitnami/minio:latest
    volumes:
      - minio_0_data_0:/bitnami/minio/data-0
      - minio_0_data_1:/bitnami/minio/data-1
    environment:
      - MINIO_ROOT_USER=minio
      - MINIO_ROOT_PASSWORD=miniosecret
      - MINIO_DISTRIBUTED_MODE_ENABLED=yes
      - MINIO_DISTRIBUTED_NODES=minio-{0...1}/bitnami/minio/data-{0...1}
  minio-1:
    image: bitnami/minio:latest
    volumes:
      - minio_1_data_0:/bitnami/minio/data-0
      - minio_1_data_1:/bitnami/minio/data-1
    environment:
      - MINIO_ROOT_USER=minio
      - MINIO_ROOT_PASSWORD=miniosecret
      - MINIO_DISTRIBUTED_MODE_ENABLED=yes
      - MINIO_DISTRIBUTED_NODES=minio-{0...1}/bitnami/minio/data-{0...1}
volumes:
  minio_0_data_0:
    driver: local
  minio_0_data_1:
    driver: local
  minio_1_data_0:
    driver: local
  minio_1_data_1:
    driver: local

Find more information about the Distributed Mode in the MinIO(R) documentation.

Reconfiguring Keys on container restarts

MinIO(R) configures the access & secret key during the 1st initialization based on the MINIO_ROOT_USER and MINIO_ROOT_PASSWORD environment variables, respetively.

When using persistence, MinIO(R) will reuse the data configured during the 1st initialization by default, ignoring whatever values are set on these environment variables. You can force MinIO(R) to reconfigure the keys based on the environment variables by setting the MINIO_FORCE_NEW_KEYS environment variable to yes:

console
docker run --name minio \
    --publish 9000:9000 \
    --publish 9001:9001 \
    --env MINIO_FORCE_NEW_KEYS="yes" \
    --env MINIO_ROOT_USER="new-minio-root-user" \
    --env MINIO_ROOT_PASSWORD="new-minio-root-password" \
    --volume /path/to/minio-persistence:/bitnami/minio/data \
    bitnami/minio:latest

FIPS configuration in Bitnami Secure Images

The Bitnami Bitnami Object Storage based on MinIO® Docker image from the Bitnami Secure Images catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

• OPENSSL_FIPS: whether OpenSSL runs in FIPS mode or not. yes (default), no.

Logging

The Bitnami MinIO(R) Docker image sends the container logs to the stdout. To view the logs:

console
docker logs minio

or using Docker Compose:

console
docker-compose logs minio

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

HTTP log trace

To enable HTTP log trace, you can set the environment variable MINIO_HTTP_TRACE to redirect the logs to a specific file as detailed at MinIO(R) documentation.

When setting this environment variable to /opt/bitnami/minio/log/minio.log, the logs will be sent to the stdout.

console
docker run --name minio \
    --publish 9000:9000 \
    --publish 9001:9001 \
    --env MINIO_HTTP_TRACE=/opt/bitnami/minio/log/minio.log \
    bitnami/minio:latest

or by modifying the https://github.com/bitnami/containers/blob/main/bitnami/minio/docker-compose.yml file present in this repository:

yaml
services:
  minio:
  ...
    environment:
      - MINIO_HTTP_TRACE=/opt/bitnami/minio/log/minio.log
  ...
