How to use ENV Template Generator

  1. 1

    Pick a source

    Start from a framework preset, paste a docker-compose.yml or Kubernetes YAML, or define variables by hand.

  2. 2

    Describe each variable

    Give custom variables a type, a required flag and a description so the template documents itself.

  3. 3

    Review the template

    Check the generated .env template and its defaults before committing it as .env.example.

  4. 4

    Copy or download

    Copy or download the template and commit it so new developers know which variables to set.

Questions and answers

What is ENV Template Generator?
An .env template, usually committed as .env.example, documents every environment variable a project needs with placeholder values instead of secrets. This tool builds one from framework presets, a docker-compose.yml, Kubernetes manifests or your own list. It uses the same engine as Environment Variable Generator.
Should I commit the template?
Commit it as .env.example with placeholder values, never real secrets. Keep the real .env out of version control.
Is my configuration uploaded?
No. Everything is generated in your browser.
