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

Minio: S3 Compatible Stoage in Docker

Minio is a distributed object storage server that is designed to be scalable and highly available. It is built for cloud-native applications and DevOps. Minio provides Amazon S3 compatible API for cloud-native applications to store and retrieve data. It is open-source and can be deployed on-premise, on the cloud or on Kubernetes.

The command docker pull minio/minio pulls the Minio image from Docker Hub. The command docker run -p 9000:9000 minio/minio server /data runs a Minio container with port forwarding from the host to the container for the Minio web interface. The /data parameter specifies the path to the data directory that will be used to store the data on the container's file system.

**We need to have the docker env up and running.

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

After running this command, you can access the Minio web interface by navigating to http://localhost:9000 in your web browser.

Inceass the Root Disk Size for Centos in Aws

Issue: Root Partition not scaled after EBS is resized.

Growpart called by cloud-init only works for kernels >3.8. Only newer kernels support changing the partition size of a mounted partition. When using an older kernel the resizing of the root partition happens in the initrd stage before the root partition is mounted and the subsequent cloud-init growpart run is a no-op.
