Using the NGINX Docker image

Docker is an effective platform for packaging and running web applications, especially when paired with cloud-based Platform as a Service (PaaS) options, and NGINX provides an official Docker image that enables DevOps teams to host web applications. This text illustrates how to use the NGINX Docker image to create and run custom web applications, starting with a basic command to launch an NGINX container and extending to the creation of custom Docker images embedding static HTML files. It delves into advanced configuration by explaining how to add custom configuration files for additional functionalities, such as a health check endpoint, and discusses the benefits of smaller image sizes using Alpine-based NGINX images compared to the default Debian-based ones. The guide concludes with a nod to other popular Docker images and resources for further exploration, highlighting the flexibility and power of using NGINX within Docker to host web applications while also mentioning tools like the Octopus Workflow Builder for deploying applications to AWS platforms.
