Deploy ephemeral websites.

Project description

Smokeshow CLI

CI license

CLI to deploy ephemeral websites, see for more information.


pip install smokeshow


To get help on usage, run:

smokeshow --help

To generate an upload key, use:

smokeshow generate-key

You should then set the key as an environment variable with


With that, you can upload a site with:

smokeshow upload path/to/upload

For more help run smokeshow upload --help, if you run smokeshow upload without either setting the SMOKESHOW_AUTH_KEY environment variable or using the --auth-key option, smokeshow will generate a new upload key before uploading the site.

If you're having trouble with python versions and accessing the CLI, you can also run the smokeshow library module as a script via

python -m smokeshow

GitHub actions & commit status integration

I build smokeshow primarily to preview documentation and coverage generate with github actions.

smokeshow therefore integrates directly with github actions to add a status to commits with a link to the newly created ephemeral site.

In addition, smokeshow has custom logic to extract the total coverage figure from HTML coverage reports to both annotate commit status updates and decide if the commit status is "success" or "failure".

Example of setting the commit status from a github action:

- run: smokeshow upload cli/htmlcov
    SMOKESHOW_GITHUB_STATUS_DESCRIPTION: CLI Coverage {coverage-percentage}
    SMOKESHOW_GITHUB_PR_HEAD_SHA: ${{ github.event.pull_request.head.sha }}

(this is taken directly from smokeshow's own CI, see here)

The following environment variables are used when setting commit statuses:

  • SMOKESHOW_GITHUB_STATUS_DESCRIPTION (or alternatively the --github-status-description CLI option) set the description for the commit status; the string {coverage-percentage} has a special meaning and will be replaced by the actual coverage percentage if it can be extract from the root index.html file being uploaded, this must be set for smokeshow to set the commit status
  • SMOKESHOW_GITHUB_COVERAGE_THRESHOLD (or alternatively the --github-coverage-threshold CLI option) decide the "state" of the commit status update; success is used if either the total coverage number isn't available or it's above the threshold, failure is used if the coverage number is below this threshold
  • SMOKESHOW_GITHUB_TOKEN this is used to authenticate the status update, more details here
  • SMOKESHOW_GITHUB_PR_HEAD_SHA or if it's omitted or empty GITHUB_SHA (which is set automatically by github actions) are used to decide which commit to set the status on. The SMOKESHOW_GITHUB_PR_HEAD_SHA: ${{ github.event.pull_request.head.sha }} trick shown above is required since github set the GITHUB_SHA env var to a merge commit on pull requests which isn't what you want
  • SMOKESHOW_GITHUB_CONTEXT suffix for github status context
  • GITHUB_REPOSITORY is set automatically by github actions, it's used to choose the repo to set the status on
