## Prerequisites

Docker installed on your machine. Download the relevant installer from [here](https://www.docker.com/community-edition#/download).

## Run Standalone Minio on Docker.

Minio needs a persistent volume to store configuration and application data. However, for testing purposes, you can launch Minio by simply passing a directory (`/export` 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.

```sh
docker run -p 9000:9000 minio/minio server /export
```

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 `/export` directories. To do this, run the below commands

#### GNU/Linux and macOS

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

#### Windows

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

## Run Distributed Minio on Docker

Distributed Minio can be deployed via [Docker Compose](https://docs.docker.com/compose/overview/) or [Swarm mode](https://docs.docker.com/engine/swarm/). 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 deploy Distributed Minio on Docker Compose, refer [this guide](http://docs.minio.io/docs/deploy-minio-on-docker-compose).
* To deploy Distributed Minio on Docker Swarm, refer [this guide](https://docs.minio.io/docs/deploy-minio-on-docker-swarm).

## Minio Docker Tips

### Minio Custom Access and Secret Keys

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.

#### GNU/Linux and macOS

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

#### Windows

```sh
docker run -p 9000:9000 --name minio1 \
  -e "MINIO_ACCESS_KEY=AKIAIOSFODNN7EXAMPLE" \
  -e "MINIO_SECRET_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" \
  -v D:\export\minio1:/export \
  -v D:\export\minio1-config:/root/.minio \
  minio/minio server /export
```
### Retrieving Container ID

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

```sh
docker ps -a
```

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

### Starting and Stopping Containers

To start a stopped container, you can use the [`docker start`](https://docs.docker.com/engine/reference/commandline/start/) command.

```sh
docker start <container_id>
```

To stop a running container, you can use the [`docker stop`](https://docs.docker.com/engine/reference/commandline/stop/) command.

```sh
docker stop <container_id>
```

### Minio container logs

To access Minio logs, you can use the [`docker logs`](https://docs.docker.com/engine/reference/commandline/logs/) command.

```sh
docker logs <container_id>
```

### Monitor Minio Docker Container

To monitor the resources used by Minio container, you can use the [`docker stats`](https://docs.docker.com/engine/reference/commandline/stats/) command.

```sh
docker stats <container_id>
```
