Welcome to the Stackhero documentation

Stackhero offers a ready-to-use Docker cloud CaaS (Containers as a Service) platform, designed for fast and reliable container deployments:

• Deploy to production with a single docker-compose up command. No additional configuration required: just launch your containers.
• Choose your own domain name, automatically secured with HTTPS (for example: https://api.your-company.com, https://www.your-company.com, or https://backoffice.your-company.com).
• Take advantage of high performance and enhanced security on private, dedicated infrastructure.
• Apply updates with a single click for simple, effortless maintenance.

Your containers can be running in production in about five minutes. Stackhero manages the infrastructure, updates, and security for you, so you can focus on developing your applications. Learn more about Docker CaaS cloud hosting.

If you wish to specify a different Node.js version, follow these steps:

1. Open the file docker/my-app.dockerfile, which defines the Docker image for your app.
2. Locate the first line that reads FROM node:<version>-alpine.
3. Replace <version> with your chosen Node.js version. It is recommended to use the Long-Term Support (LTS) version. You can check the latest LTS version on the Node.js website. For example, to use the latest LTS version (currently 22), update the line to FROM node:22-alpine. If you prefer a specific version number, you can use something like FROM node:22.13.0-alpine.
4. Save your changes to the Dockerfile.
