# Deploy MinIO on Chrooted Environment [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io) [![Docker Pulls](https://img.shields.io/docker/pulls/minio/minio.svg?maxAge=604800)](https://hub.docker.com/r/minio/minio/)

Chroot allows user based namespace isolation on many standard Linux deployments.

## 1. Prerequisites

- Familiarity with [chroot](http://man7.org/linux/man-pages/man2/chroot.2.html)
- Chroot installed on your machine.

			chroot --userspec=${MINIO_UID}:${MINIO_GID} / "$@"
		else
			echo "${MINIO_USERNAME}:x:1000:1000:${MINIO_USERNAME}:/:/sbin/nologin" >>/etc/passwd
			echo "${MINIO_GROUPNAME}:x:1000" >>/etc/group
			chroot --userspec=${MINIO_USERNAME}:${MINIO_GROUPNAME} / "$@"
