MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. It is API compatible with Amazon S3 cloud storage service. Use MinIO to build high performance infrastructure for machine learning, analytics and application data workloads.
This README provides quickstart instructions on running MinIO on bare metal hardware, including container-based installations. For Kubernetes environments, use the MinIO Kubernetes Operator.
Use the following commands to run a standalone MinIO server as a container.
Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically, with a minimum of 4 drives per MinIO server. See MinIO Erasure Code Quickstart Guide for more complete documentation.
Run the following command to run the latest stable image of MinIO as a container using an ephemeral data volume:
podman run -p 9000:9000 -p 9001:9001 \
quay.io/minio/minio server /data --console-address ":9001"
The MinIO deployment starts using default root credentials minioadmin:minioadmin
. You can test the deployment using the MinIO Console, an embedded
object browser built into MinIO Server. Point a web browser running on the host machine to http://127.0.0.1:9000 and log in with the
root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.
You can also connect using any S3-compatible tool, such as the MinIO Client mc
commandline tool. See
Test using MinIO Client mc
for more information on using the mc
commandline tool. For application developers,
see https://docs.min.io/docs/ and click MinIO SDKs in the navigation to view MinIO SDKs for supported languages.
NOTE: To deploy MinIO on with persistent storage, you must map local persistent directories from the host OS to the container using the
podman -v
option. For example,-v /mnt/data:/data
maps the host OS drive at/mnt/data
to/data
on the container.
Use the following commands to run a standalone MinIO server on macOS.

with the path to the drive or directory in which you want MinIO to store data.
brew install minio/stable/minio
minio server /data
NOTE: If you previously installed minio using
brew install minio
then it is recommended that you reinstall minio fromminio/stable/minio
official repo instead.
brew uninstall minio

MinIO strongly recommends against using compiled-from-source MinIO servers for production environments.
By default MinIO uses the port 9000 to listen for incoming connections. If your platform blocks the port by default, you may need to enable access to the port.
For hosts with ufw enabled (Debian based distros), you can use ufw
command to allow traffic to specific ports. Use below command to allow access to port 9000
ufw allow 9000
Below command enables all incoming traffic to ports ranging from 9000 to 9010.
ufw allow 9000:9010/tcp
For hosts with firewall-cmd enabled (CentOS), you can use firewall-cmd
command to allow traffic to specific ports. Use below commands to allow access to port 9000
firewall-cmd --get-active-zones
This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is public
, use
firewall-cmd --zone=public --add-port=9000/tcp --permanent
Note that permanent
makes sure the rules are persistent across firewall start, restart or reload. Finally reload the firewall for changes to take effect.
firewall-cmd --reload
For hosts with iptables enabled (RHEL, CentOS, etc), you can use iptables
command to enable all traffic coming to specific ports. Use below command to allow
access to port 9000
iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart
Below command enables all incoming traffic to ports ranging from 9000 to 9010.
iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
service iptables restart
When deployed on a single drive, MinIO server lets clients access any pre-existing data in the data directory. For example, if MinIO is started with the command minio server /mnt/data
, any pre-existing data in the /mnt/data
directory would be accessible to the clients.
The above statement is also valid for all gateway backends.
MinIO Server comes with an embedded web based object browser. Point your web browser to http://127.0.0.1:9000 to ensure your server has started successfully.
NOTE: MinIO runs console on random port by default if you wish choose a specific port use
--console-address
to pick a specific interface and port.
MinIO redirects browser access requests to the configured server port (i.e. 127.0.0.1:9000
) to the configured Console port. MinIO uses the hostname or IP address specified in the request when building the redirect URL. The URL and port must be accessible by the client for the redirection to work.
For deployments behind a load balancer, proxy, or ingress rule where the MinIO host IP address or port is not public, use the MINIO_BROWSER_REDIRECT_URL
environment variable to specify the external hostname for the redirect. The LB/Proxy must have rules for directing traffic to the Console port specifically.
For example, consider a MinIO deployment behind a proxy https://minio.example.net
, https://console.minio.example.net
with rules for forwarding traffic on port :9000 and :9001 to MinIO and the MinIO Console respectively on the internal network. Set MINIO_BROWSER_REDIRECT_URL
to https://console.minio.example.net
to ensure the browser receives a valid reachable URL.
Similarly, if your TLS certificates do not have the IP SAN for the MinIO server host, the MinIO Console may fail to validate the connection to the server. Use the MINIO_SERVER_URL
environment variable and specify the proxy-accessible hostname of the MinIO server to allow the Console to use the MinIO server API using the TLS certificate.
For example: export MINIO_SERVER_URL="https://minio.example.net"

mc
provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services. Follow the MinIO Client Quickstart Guide for further instructions.
Upgrades require zero downtime in MinIO, all upgrades are non-disruptive, all transactions on MinIO are atomic. So upgrading all the servers simultaneously is the recommended way to upgrade MinIO.
NOTE: requires internet access to update directly from https://dl.min.io, optionally you can host any mirrors at https://my-artifactory.example.com/minio/
- For deployments that installed the MinIO server binary by hand, use
mc admin update
mc admin update <minio alias, e.g., myminio>
-
For deployments without external internet access (e.g. airgapped environments), download the binary from https://dl.min.io and replace the existing MinIO binary let's say for example
/opt/bin/minio
, apply executable permissionschmod +x /opt/bin/minio
and domc admin service restart alias/
. -
For RPM/DEB installations, upgrade packages parallelly on all servers. Once upgraded, perform
systemctl restart minio
across all nodes in parallel. RPM/DEB based installations are usually automated usingansible
.
- Test all upgrades in a lower environment (DEV, QA, UAT) before applying to production. Performing blind upgrades in production environments carries significant risk.
- Read the release notes for the targeted MinIO release before performing any installation, there is no forced requirement to upgrade to latest releases every week. If it has a bug fix you are looking for then yes, else avoid actively upgrading a running production system.
- Make sure MinIO process has write access to
/opt/bin
if you plan to usemc admin update
. This is needed for MinIO to download the latest binary from https://dl.min.io and save it locally for upgrades. mc admin update
is not supported in kubernetes/container environments, container environments provide their own mechanisms for container updates.- We do not recommend upgrading one MinIO server at a time, the product is designed to support parallel upgrades please follow our recommended guidelines.
