Save time and simplify your life: it only takes 5 minutes to try Stackhero's MinIO Object Storage hosting solution!

This guide explains how to create a MinIO service, access its credentials, and update its configuration entirely from the command line, without any clicks in the dashboard. This approach is ideal for scripts, CI pipelines, and AI agents.

We will use the Stackhero CLI for all operations. If you have not already installed it, you can do so with:

curl -fsSL https://www.stackhero.io/install.sh | sh

1. Authenticate

The simplest way to get started is to log in through your browser. When you run the login command, the CLI opens a web page where you can approve access. No passwords or 2FA codes are entered directly into the CLI.

stackhero login

After logging in, your credentials are stored locally and will be used automatically by future CLI commands.

For fully automated environments such as scripts or CI pipelines, you may prefer a non-interactive access token. You can create one from your dashboard (Account > Access tokens), then export it as an environment variable. The CLI, as well as any script you run, will automatically detect it.

export STACKHERO_TOKEN="usr-xxxxxx:your-token"

2. Find the MinIO service store

Next, you will want to list the MinIO service stores available to your account. The CLI accepts the store name (minio) directly, so there is no need to look up or copy any IDs.

# List MinIO service stores (add --organization if you manage more than one)
stackhero services-store-list --name="minio"

You can use the store name minio in subsequent commands, or select a specific svs-xxxxxx ID from the list if you prefer.

3. Choose an instance size and a region

# List instance sizes for your service store (use the NAME column for --instance)
stackhero instances-store-list --service-store=minio

# List available regions (names like "europe")
stackhero regions-list

4. Create the service

Below is a sample script that creates a stack, adds your MinIO service to it, waits for it to start, retrieves its configuration (including generated credentials), and then applies a new configuration.

#!/bin/bash
set -e

export STACKHERO_TOKEN="usr-xxxxxx:your-token"

serviceStore="minio"   # The MinIO service store name (see step 2)
instance="..."                # An instance size from step 3
region="europe"               # A region name from step 3

# Create a stack for your service (uses your default organization; add --organization if needed)
stackId=$(stackhero --format=script stack-create \
  --name="My MinIO stack")
echo "Stack created: ${stackId}"

# Add MinIO to the stack (names are resolved automatically)
serviceId=$(stackhero --format=script service-add \
  --stack="My MinIO stack" \
  --service-store="${serviceStore}" \
  --instance="${instance}" \
  --region="${region}")
echo "Service added: minio"

# Wait for the service to be fully operational (this may take a few minutes)
stackhero service-wait-for --service="minio"

# Retrieve the service configuration, including generated credentials
stackhero service-configuration-get --service="minio" --format=json

5. Retrieve credentials

The service-configuration-get command returns the complete configuration for your service, including auto-generated passwords and connection details. The output is in JSON format, making it easy to use in scripts and automation.

stackhero service-configuration-get --service=svc-xxxxxx --format=json

6. Change the configuration

You can review an example configuration schema and then apply your own settings. When you update the configuration, the service may restart to apply the changes.

# View the configuration schema and an example for your service
stackhero service-configuration-example --service=svc-xxxxxx

# Apply a custom configuration (the service restarts if needed)
stackhero service-configuration-set \
  --service=svc-xxxxxx \
  --configuration='{ "...": "..." }'

# Wait for the new configuration to be applied
stackhero service-wait-for --service=svc-xxxxxx

That's it. You have now seen the full lifecycle: start a service, retrieve its credentials, and reconfigure it, all in a scriptable, automated way. To learn more, refer to the full CLI documentation, which also covers the non-interactive STACKHERO_TOKEN authentication demonstrated here.
