Introducing ConfigMap and Secret Files

Today we are pleased to introduce secret files on Northflank. For Kubernetes users this capability is known as ConfigMaps, Docker users as volume -v ./config.yaml:/var/application/config.yaml and PaaS users as secret files. Ensuring compatibility with these three different use-cases was essential. Users will be able to use secret files in their workflows alongside secret groups, environment variables in deployments and builds seamlessly.

Secret Files

  • Allow writing of files to specific paths in your runtime container or build process
  • Encrypted at rest and injected at runtime with environment variables
  • Has access to variable templating enabling inheritance of other environment values or connection strings

Use Cases:

  • You need to configure a third party docker image via config files located at specific paths
  • You need to create text based configuration files like .json, .html, .css, .yaml to power software like nginx, kong, supabase and more
  • You need to add a certificate file or complex secret that cannot be handled via an environment variable
  • Create manifest files with build or runtime variable configuration



  • PR numbers in responses are now returned as integers in line with the response schema

Features & fixes:

  • Fixed an issue where two builds could be triggered at once on initial creation from template
  • Links in the instance log feed are now marked up
