Prometheus: 6. Change the configuration

This documentation is part of the Automate with the CLI guide. You can view the complete guide here: Start Prometheus, retrieve its credentials, and modify its configuration programmatically using the Stackhero CLI.

👋 Welcome to the Stackhero documentation!

Stackhero offers a ready-to-use Prometheus cloud solution designed for reliability and simplicity:

• Alert Manager is included, allowing you to send alerts directly to Slack, Mattermost, PagerDuty, and other popular platforms.
• A dedicated email server enables you to send unlimited email alerts with no additional configuration required.
• Blackbox is provided, so you can probe HTTP, ICMP, TCP, and more for comprehensive monitoring.
• Simple configuration with the online configuration file editor—no need to manage YAML manually.
• Easy updates with just one click.
• Optimal performance and enhanced security thanks to your own private, dedicated VM.

Save time and make your life easier: it takes just 5 minutes to try Stackhero's Prometheus cloud hosting solution!

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 necessary)
stackhero service-configuration-set \
  --service=svc-xxxxxx \
  --configuration='{ "...": "..." }'

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

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