Get started quickly: it only takes 5 minutes to launch your Mercure-Hub cloud hosting environment and start sending real-time updates to your applications.
Below is a sample script that creates a stack, adds your Mercure Hub 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="mercure-hub" # The Mercure Hub 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 Mercure Hub stack")
echo "Stack created: ${stackId}"
# Add Mercure Hub to the stack (names are resolved automatically)
serviceId=$(stackhero --format=script service-add \
--stack="My Mercure Hub stack" \
--service-store="${serviceStore}" \
--instance="${instance}" \
--region="${region}")
echo "Service added: mercure-hub"
# Wait for the service to be fully operational (this may take a few minutes)
stackhero service-wait-for --service="mercure-hub"
# Retrieve the service configuration, including generated credentials
stackhero service-configuration-get --service="mercure-hub" --format=json
