# Minio Docker Quickstart Guide [![Gitter](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/minio/minio?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)

## 1. Test Minio Docker Container
Minio generates new access and secret keys each time you run this command. Container state is lost after you end this session. This mode is only intended for testing purpose.

```sh

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

```

## 2. Run One Minio Docker Container

Minio container requires a persistent volume to store configuration and application data. Following command maps local persistent directories from the host OS to virtual config `~/.minio` and export `/export` directories.

```sh

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

```

## 3. 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.

```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

```

## 4. Run Minio in clustered mode

Let's consider that we need to run 4 minio servers inside different docker containers. The `docker-compose.yml` file in the root of the project sets this up using the [docker-compose](https://docs.docker.com/compose/) tool.

### Start Minio docker instances

From the root directory of the project, run:

``` shell
$ docker-compose up
```

Each instance's minio web-server is accessible on the host at ports 9001 through 9004, so you may access the first one at http://localhost:9001/
