Hello from Docker! This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the „hello-world“ image from the Docker Hub. (arm64v8) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal.
To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash

MinIO server supports rolling upgrades, i.e. you can update one MinIO instance at a time in a distributed cluster and this allows upgrades with no downtime. Upgrades can be done manually by replacing the binary with the latest release and restarting all servers in a rolling fashion. However we recommend all our users to use mc admin update from the client. This will update all the nodes in the cluster simultaneously and restart them as shown in the following command from the MinIO client (mc)
