# MinIO Docker Quickstart Guide [](https://slack.min.io) [](https://hub.docker.com/r/minio/minio/)
|
|
|
|
## 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 (`/data` 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 /data
|
|
```
|
|
|
|
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 `/data` directories. To do this, run the below commands
|
|
|
|
#### GNU/Linux and macOS
|
|
```sh
|
|
docker run -p 9000:9000 --name minio1 \
|
|
-v /mnt/data:/data \
|
|
minio/minio server /data
|
|
```
|
|
|
|
#### Windows
|
|
```sh
|
|
docker run -p 9000:9000 --name minio1 \
|
|
-v D:\data:/data \
|
|
minio/minio server /data
|
|
```
|
|
|
|
## Run Distributed MinIO on Docker
|
|
Distributed MinIO can be deployed via [Docker Compose](https://docs.min.io/docs/deploy-minio-on-docker-compose) or [Swarm mode](https://docs.min.io/docs/deploy-minio-on-docker-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.

## 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/data:/data \
|
|
minio/minio server /data
|
|
```
|
|
|
|
#### Windows
|
|
```powershell
|
|
docker run -p 9000:9000 --name minio1 \
|
|
-e "MINIO_ACCESS_KEY=AKIAIOSFODNN7EXAMPLE" \
|
|
-e "MINIO_SECRET_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" \
|
|
-v D:\data:/data \
|
|
minio/minio server /data
|
|
```
|
|
|
|
### Run MinIO Docker as a regular user
|
|
Docker provides standardized mechanisms to run docker containers as non-root users.
|
|
|
|
#### GNU/Linux and macOS
|
|
On Linux and macOS you can use `--user` to run the container as regular user.
|
|
|
|
> NOTE: make sure --user has write permission to *${HOME}/data* prior to using `--user`.
|
|
```sh
|
|
mkdir -p ${HOME}/data
|
|
docker run -p 9000:9000 \
|
|
--user $(id -u):$(id -g) \
|
|
--name minio1 \
|
|
-e "MINIO_ACCESS_KEY=AKIAIOSFODNN7EXAMPLE" \
|
|
-e "MINIO_SECRET_KEY=wJalrXUtnFEMIK7MDENGbPxRfiCYEXAMPLEKEY" \
|
|
-v ${HOME}/data:/data \
|
|
minio/minio server /data
|
|
```
|
|
|
|
#### Windows
|
|
On windows you would need to use [Docker integrated windows authentication](https://success.docker.com/article/modernizing-traditional-dot-net-applications#integratedwindowsauthentication) and [Create a container with Active Directory Support](https://blogs.msdn.microsoft.com/containerstuff/2017/01/30/create-a-container-with-active-directory-support/)
|
|
|
|
> NOTE: make sure your AD/Windows user has write permissions to *D:\data* prior to using `credentialspec=`.
|
|
|
|
```powershell
|
|
docker run -p 9000:9000 \
|
|
--name minio1 \
|
|
--security-opt "credentialspec=file://myuser.json"
|
|
-e "MINIO_ACCESS_KEY=AKIAIOSFODNN7EXAMPLE" \
|
|
-e "MINIO_SECRET_KEY=wJalrXUtnFEMIK7MDENGbPxRfiCYEXAMPLEKEY" \
|
|
-v D:\data:/data \
|
|
minio/minio server /data
|
|
```
|
|
|
|
### MinIO Custom Access and Secret Keys using Docker secrets
|
|
To override MinIO's auto-generated keys, you may pass secret and access keys explicitly by creating access and secret keys as [Docker secrets](https://docs.docker.com/engine/swarm/secrets/). MinIO server also allows regular strings as access and secret keys.
|
|
|
|
```
|
|
echo "AKIAIOSFODNN7EXAMPLE" | docker secret create access_key -
|
|
echo "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" | docker secret create secret_key -
|
|
```
|
|
|
|
Create a MinIO service using `docker service` to read from Docker secrets.
|
|
```
|
|
docker service create --name="minio-service" --secret="access_key" --secret="secret_key" minio/minio server /data
|
|
```
|
|
|
|
Read more about `docker service` [here](https://docs.docker.com/engine/swarm/how-swarm-mode-works/services/)
|
|
|
|
#### MinIO Custom Access and Secret Key files
|
|
To use other secret names follow the instructions above and replace `access_key` and `secret_key` with your custom names (e.g. `my_secret_key`,`my_custom_key`). Run your service with
|
|
```
|
|
docker service create --name="minio-service" \
|
|
--secret="my_access_key" \
|
|
--secret="my_secret_key" \
|
|
--env="MINIO_ACCESS_KEY_FILE=my_access_key" \
|
|
--env="MINIO_SECRET_KEY_FILE=my_secret_key" \
|
|
minio/minio server /data
|
|
```
|
|
|
|
### 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>
|
|
```
