Docker is a popular open-source platform for developing, shipping, and running applications. It encapsulates applications and their dependencies in containers to promote consistency across different environments. This consistency helps prevent issues related to dependency conflicts and “it works on my machine” discrepancies.
With Docker, you can define the necessary dependencies and extensions using Dockerfiles. This means your applications have all the required libraries and tools in a reproducible, isolated environment.
Kinsta Application Hosting offers dynamic support for custom Dockerfiles, which allows you to have greater control of your application’s environment. With a Dockerfile, you can use almost any language—you’re not restricted to the languages supported by Nixpacks or Buildpacks.
