Minio needs a persistent volume to store configuration and application data. However, for testing purposes, you can launch Minio by simply passing a directory (/data in the example below). This directory gets created in the container filesystem at the time of container start. But all the data is lost after container exits.

docker run -p 9000:9000 minio/minio server /data

To create a Minio container with persistent storage, you need to map local persistent directories from the host OS to virtual config ~/.minio and export /data directories. To do this, run the below commands

docker run -p 9000:9000 --name minio1 \
  -v /mnt/data:/data \
  -v /mnt/config:/root/.minio \
  minio/minio server /data

docker run -p 9000:9000 --name minio1 \
  -v D:\data:/data \
  -v D:\minio\config:/root/.minio \
  minio/minio server /data

Distributed Minio can be deployed via Docker Compose or Swarm mode. The major difference between these two being, Docker Compose creates a single host, multi-container deployment, while Swarm mode creates a multi-host, multi-container deployment.

This means Docker Compose lets you quickly get started with Distributed Minio on your computer - ideal for development, testing, staging environments. While deploying Distributed Minio on Swarm offers a more robust, production level deployment.

To override Minio's auto-generated keys, you may pass secret and access keys explicitly as environment variables. Minio server also allows regular strings as access and secret keys.

docker run -p 9000:9000 --name minio1 \
  -e "MINIO_ACCESS_KEY=AKIAIOSFODNN7EXAMPLE" \
  -e "MINIO_SECRET_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" \
  -v /mnt/data:/data \
  -v /mnt/config:/root/.minio \
  minio/minio server /data

docker run -p 9000:9000 --name minio1 \
  -e "MINIO_ACCESS_KEY=AKIAIOSFODNN7EXAMPLE" \
  -e "MINIO_SECRET_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" \
  -v D:\data:/data \
  -v D:\minio\config:/root/.minio \
  minio/minio server /data

To override Minio's auto-generated keys, you may pass secret and access keys explicitly by creating access and secret keys as Docker secrets. Minio server also allows regular strings as access and secret keys.

echo "AKIAIOSFODNN7EXAMPLE" | docker secret create access_key -
echo "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" | docker secret create secret_key -

Create a Minio service using docker service to read from Docker secrets.

docker service create --name="minio-service" --secret="access_key" --secret="secret_key" minio/minio server /data

To use other secret names follow the instructions above and replace access_key and secret_key with your custom names (e.g. my_secret_key,my_custom_key). Run your service with

docker service create --name="minio-service" \
  --secret="my_access_key" \
  --secret="my_secret_key" \
  --env="MINIO_ACCESS_KEY_FILE=my_access_key" \
  --env="MINIO_SECRET_KEY_FILE=my_secret_key" \
  minio/minio server /data

To use Docker commands on a specific container, you need to know the Container ID for that container. To get the Container ID, run

docker ps -a

-a flag makes sure you get all the containers (Created, Running, Exited). Then identify the Container ID from the output.

To start a stopped container, you can use the docker start command.

docker start <container_id>

To stop a running container, you can use the docker stop command.

docker stop <container_id>

To access Minio logs, you can use the docker logs command.

docker logs <container_id>

To monitor the resources used by Minio container, you can use the docker stats command.

docker stats <container_id>
