Docker environments require special Puppeteer configuration due to sandboxing restrictions.

Unlighthouse Config

It's recommended you only use the @unlighthouse/ci with Docker. Hosting the client does not have known support.

You will need to remove the Chrome sandbox in a Docker environment, this will require using an unlighthouse.config.ts file.

import { defineUnlighthouseConfig } from 'unlighthouse/config'

export default defineUnlighthouseConfig({
  puppeteerOptions: {
    headless: true,
    args: [
      '--no-sandbox',
      '--disable-setuid-sandbox',
      '--disable-gpu',
      '--ignore-certificate-errors',
    ],
  },
})

If you're using the unlighthouse binary instead of the CI integration, then you will need to tell Unlighthouse not to use the server and close when the reports are finished.

export default defineUnlighthouseConfig({
  server: {
    open: false,
  },
  hooks: {
    'worker-finished': async () => {
      process.exit(0)
    },
  },
})
