+# Getting Started with Apache Polaris and MinIO
+
+## Overview
+
+This example uses MinIO as a storage provider with Polaris.
+
+Spark is used as a query engine. This example assumes a local Spark
installation.
+See the [Spark Notebooks Example](../spark/README.md) for a more advanced
Spark setup.
+
+## Starting the Example
+
+1. Build the Polaris server image if it's not already present locally:
+
+ ```shell
+ ./gradlew \
+ :polaris-server:assemble \
+ :polaris-server:quarkusAppPartsBuild --rerun \
+ -Dquarkus.container-image.build=true
+ ```
+
+2. Start the docker compose group by running the following command from the
root of the repository:
+
+ ```shell
+ docker compose -f getting-started/minio/docker-compose.yml up
+ ```
+
+## Connecting From Spark
+
+```shell
+bin/spark-sql \
+ --packages
org.apache.iceberg:iceberg-spark-runtime-3.5_2.12:1.9.0,org.apache.iceberg:iceberg-aws-bundle:1.9.0
\
+ --conf
spark.sql.extensions=org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions
\
+ --conf spark.sql.catalog.polaris=org.apache.iceberg.spark.SparkCatalog \
+ --conf spark.sql.catalog.polaris.type=rest \
+ --conf spark.sql.catalog.polaris.uri=http://localhost:8181/api/catalog \
+ --conf spark.sql.catalog.polaris.token-refresh-enabled=false \
+ --conf spark.sql.catalog.polaris.warehouse=quickstart_catalog \
+ --conf spark.sql.catalog.polaris.scope=PRINCIPAL_ROLE:ALL \
+ --conf
spark.sql.catalog.polaris.header.X-Iceberg-Access-Delegation=vended-credentials
\
+ --conf spark.sql.catalog.polaris.credential=root:s3cr3t
+```
+
+Note: `s3cr3t` is defined as the password for the `root` users in the
`docker-compose.yml` file.
+
+## Running Queries
+
+Run inside the Spark SQL shell:
+
+```
+spark-sql (default)> use polaris;
+Time taken: 0.837 seconds
+
+spark-sql ()> create namespace ns;
+Time taken: 0.374 seconds
+
+spark-sql ()> create table ns.t1 as select 'abc';
+Time taken: 2.192 seconds
+
+spark-sql ()> select * from ns.t1;
+abc
+Time taken: 0.579 seconds, Fetched 1 row(s)
+```
+
+## MinIO Endpoints
+
+Note that the catalog configuration defined in the `docker-compose.yml`
contains
+different endpoints for the Polaris Server and the client (Spark).
Specifically,
+the client endpoint is `http://localhost:9000`, but `endpointInternal` is
`http://minio:9000`.
+
+This is necessary because clients running on `localhost` do not normally see
service
+names (such as `minio`) that are internal to the docker compose environment.

+Title: Deploying Polaris on MinIO
+type: docs
+weight: 350
+---
+
+In this guide we walk through setting up a simple Polaris Server with local
[MinIO](https://www.min.io/) storage.
+
+Similar configurations are expected to work with other S3-compatible systems
that also have the
+[STS](https://docs.aws.amazon.com/STS/latest/APIReference/welcome.html) API.
+
+# Setup
+
+Clone the Polaris source repository, then build a docker image for Polaris.
+
+```shell
+./gradlew :polaris-server:assemble -Dquarkus.container-image.build=true
+```
+
+Start MinIO with Polaris using the `docker compose` example.
+
+```shell
+docker compose -f getting-started/minio/docker-compose.yml up
+```
+
+The compose script will start MinIO on default ports (API on 9000, UI on 9001)
+plus a Polaris Server pre-configured to that MinIO instance.
+
+In this example the `root` principal has its password set to `s3cr3t`.
+
+# Connecting from Spark
+
+Start Spark.
+
+```shell
+export AWS_REGION=us-west-2
+
+bin/spark-sql \
+ --packages
org.apache.iceberg:iceberg-spark-runtime-3.5_2.12:1.9.0,org.apache.iceberg:iceberg-aws-bundle:1.9.0
\
+ --conf
spark.sql.extensions=org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions
\
+ --conf spark.sql.catalog.polaris=org.apache.iceberg.spark.SparkCatalog \
+ --conf spark.sql.catalog.polaris.type=rest \
+ --conf spark.sql.catalog.polaris.uri=http://localhost:8181/api/catalog \
+ --conf spark.sql.catalog.polaris.token-refresh-enabled=false \
+ --conf spark.sql.catalog.polaris.warehouse=quickstart_catalog \
+ --conf spark.sql.catalog.polaris.scope=PRINCIPAL_ROLE:ALL \
+ --conf
spark.sql.catalog.polaris.header.X-Iceberg-Access-Delegation=vended-credentials
\
+ --conf spark.sql.catalog.polaris.credential=root:s3cr3t
+```
+
+Note: `AWS_REGION` is required by the AWS SDK used by Spark, but the value is
irrelevant in this case.
+
+Create a table in Spark.
+
+```sql
+use polaris;
+create namespace ns;
+create table ns.t1 as select 'abc';
+select * from ns.t1;
+```
+
+# Connecting from MinIO client
+
+```shell
+mc alias set pol http://localhost:9000 minio_root m1n1opwd
+mc ls pol/bucket123/ns/t1
+[2025-08-13 18:52:38 EDT] 0B data/
+[2025-08-13 18:52:38 EDT] 0B metadata/
+```
+
+Note: the values of `minio_root`, `m1n1opwd` and `bucket123` are defined in
the docker compose file.
+
+# Notes on Storage Configuation
+
+In this example the Polaris Catalog is defined as (excluding uninteresting
properties):
+
+```json
+ {
+ "name": "quickstart_catalog",
+ "storageConfigInfo": {
+ "endpoint": "http://localhost:9000";,
+ "endpointInternal": "http://minio:9000";,
+ "pathStyleAccess": true,
+ "storageType": "S3",
+ "allowedLocations": [
+ "s3://bucket123"
+ ]
+ }
+ }
+```
+
+Note that the `roleArn` parameter, which is required for AWS storage, does not
need to be set for MinIO.
+
+Note the two endpoint values. `endpointInternal` is used by the Polaris
Server, while `endpoint` is communicated
+to clients (such as Spark) in Iceberg REST API responses. This distinction
allows the system to work smoothly
+when the clients and the server have different views of the network (in this
example the host name `minio` is
+resolvable only inside the docker compose environment).
