Minio Running as Service

Minio is a distributed object storage server, similar to Amazon S3, that allows you to store and access large amounts of data. Since the service is running on different hosts, it is important to have a shared storage mechanism so that the data is synchronized across all nodes. To achieve this, a bind mount is used to mount a directory on the host machine to the Minio server container, allowing it to read and write data to the directory. Additionally, two Docker secrets are created for access and secret keys to authenticate and authorize access to the Minio server. Finally, the service is created with the docker service create command, specifying the name of the service, the port to publish, the constraint to run the service only on a manager node, the bind mount for data synchronization, and the two Docker secrets for authentication. The minio/minio image is used to run the Minio server, and the /data directory is specified as the location to store data.

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

docker service create --name="minio-service" --publish 9000:9000   --constraint 'node.role == manager' --mount type=bind,src=/mnt/minio/,dst=/data --secret="access_key" --secret="secret_key" minio/minio server /data
