Inputs

Provide the following 2 values to run the Dockerfile Generator:

  • Base Image [select] (required)
  • Exposed Port [number] — default 3000

What it calculates

This tool returns:

  • Base Image — primary result
  • Port
  • Est. Size

Worked example

For the sample inputs below:

  • Base Image: node:18-alpine
  • Exposed Port: 3000

the Dockerfile Generator produces:

  • Base Image: node:18-alpine
  • Port: 3000
  • Est. Size: Small (~50-150MB)

How it works

The result is derived through the following steps:

  1. isAlpine = baseImage.includes('alpine') || baseImage.includes('slim')
  2. sizeEstimate = isAlpine ? 'Small (~50-150MB)' : 'Medium (~200-500MB)'
