For security reasons, Trino built by Minimus includes only 5 of the 54 plugins in the public image:
  • Only plugins that operate entirely within the Trino JVM or use the local filesystem are included by default in the Minimus Trino image.
  • Plugins that require external databases, cloud SDKs, or network endpoints to function are excluded by default.
To add more plugins, create a private image using Creator to install the plugins. The trino plugins are packaged by Minimus and have the same names as the original public plugins. For example: trino-plugin-cassandra, trino-plugin-hive, etc. If you’re working with a Trino-FIPS image, install the Trino FIPS compatible plugins, for example trino-fips-plugin-cassandra.
Trino plugins are tightly coupled to the exact server build. Creator handles these compatibility issues automatically.

​
Install Plugins with Creator

The standard way to install Trino plugins when working with a Minimus Trino image is to create a private image using Creator.
  1. Go to Creator
  2. Select the Minimus Trino image as your starter image
  3. Select the relevant packages. They’re named trino-plugin-{name}.
  4. Finish configuring your private image, adding env variables, certificates, etc. If you’re using a Trino-FIPS starter image, install the FIPS plugins (their name takes the format: trino-fips-plugin-{plugin-name}).
  5. Save and build the private image. Creator will build your custom Trino image in all available versions with the plugins of your choice and maintain it for you.

Example: Configuring the MySQL Catalog for Trino

The following example uses a private Trino image with the MySQL connector plugin baked in. To query a MySQL database through Trino, you need to register it as a catalog. This tutorial walks through the setup using Docker. We will deploy a custom Trino image alongside a MySQL instance and run a federated query across MySQL and Trino’s built-in sample data.

​
Prerequisites

  • Docker installed and running

​
Step 1: Start MySQL

Create a Docker network and start a MySQL container with a sample database: 
docker network create trino-test

docker run -d --rm --name mysql --network trino-test \
  -e MYSQL_ROOT_PASSWORD=demo \
  -e MYSQL_DATABASE=shop \
  reg.mini.dev/mysql:8
Wait a few seconds for MySQL to initialize, then seed a sample table: 
docker exec -i mysql mysql -uroot -pdemo shop <<'SQL'
CREATE TABLE products (
  id INT PRIMARY KEY,
  name VARCHAR(100),
  price DECIMAL(10,2)
);
INSERT INTO products VALUES
  (1, 'Keyboard', 49.99),
  (2, 'Monitor', 299.99),
  (3, 'Mouse', 24.99);
SQL

​
Step 2: Write the Catalog Properties

Create a file called mysql.properties in your working directory: 
connector.name=mysql
connection-url=jdbc:mysql://mysql:3306
connection-user=root
connection-password=demo
This tells Trino how to connect to the MySQL instance. The hostname mysql matches the container name on the Docker network.

​
Step 3: Start Trino

Use Creator to build a private image with the package trino-plugin-mysql and name it trino-mysql. Run the Trino-MySQL image and mount the catalog file (replace the {id} with your own tenant ID before running the command): 
docker run -d --rm --name trino --network trino-test \
  -p 8080:8080 \
  -v $(pwd)/mysql.properties:/etc/trino/catalog/mysql.properties \
  reg.mini.dev/{id}/trino-mysql:latest
Wait for Trino to finish starting up (about 30 seconds), then confirm the MySQL catalog is registered: 
docker exec trino trino --execute "SHOW CATALOGS"
You should see mysql in the output alongside the default catalogs (system, tpch, etc.).

​
Step 4: Query MySQL through Trino

List the tables in the shop database: 
docker exec trino trino --execute "SHOW TABLES FROM mysql.shop"
Query the products table: 
docker exec trino trino --execute "SELECT * FROM mysql.shop.products"
You should see the three rows inserted earlier.

​
Step 5: Run a Federated Query

One of Trino’s strengths is querying across multiple data sources in a single statement. Join the MySQL table with the built-in tpch sample data: 
docker exec trino trino --execute "
SELECT p.name, p.price, n.name AS nation
FROM mysql.shop.products p
CROSS JOIN tpch.tiny.nation n
WHERE n.nationkey < 3
ORDER BY p.name, n.name
"
This query pulls products from MySQL and nations from the in-memory tpch catalog, all in one pass.

​
Clean Up

Remove the containers and network: 
docker rm -f trino mysql && docker network rm trino-test

​
Catalog Reference

​
How catalogs work

Trino uses catalog properties files to register data sources. Each .properties file placed in /etc/trino/catalog/ becomes a catalog with the filename as its name (e.g., mysql.properties registers a catalog called mysql). Queries follow a three-part naming convention: catalog.schema.table.

​
Mounting catalogs in Kubernetes

When deploying with the Trino Helm chart, add catalogs through the additionalCatalogs field in your values.yaml: 
additionalCatalogs:
  mysql: |
    connector.name=mysql
    connection-url=jdbc:mysql://mysql-host:3306
    connection-user=trino
    connection-password=secret
Each key becomes a catalog name and the value is the contents of the properties file. See the Trino Helm chart documentation for the full set of options.

​
Connection properties

PropertyDescription
connector.nameAlways mysql for the MySQL connector
connection-urlJDBC URL in the form jdbc:mysql://host:port
connection-userMySQL user for Trino to authenticate as
connection-passwordPassword for the MySQL user
For the full list of tuning and security options, see the Trino MySQL connector docs.
