wercker - your new favorite dev tool

wercker status

This is the project for wercker, the command-line tool that powers all the build and deploy jobs for, it runs on your local machine with the help of Docker.

Wercker is designed to increase developer velocity by enabling users to run and automate their tests and builds, leveraging Docker containers to provide development environments for multi-service architectures.

Note: While the Wercker team has extensive experience with open source, this project has been internal for some time and may have some rough edges. We'll be actively prettying up the codebase and the project, but we wanted to release it to you as early as possible.

The master branch may be in a broken or unstable state during development. It is recommended that you download wercker through the CLI section on our website, if you're not contributing to the code base.

Building wercker

wercker is built using Go version 1.5 or greater. If you don't have it already, you can get it from the official download page. Once you go installed, set up your go environment by using this guide

Next, you'll need govendor to install the golang dependencies. You can do this by running:

  go get

In Go 1.5 you'll need the vendor experiment enabled, so make sure to export GO15VENDOREXPERIMENT=1 in your shell (see Go 1.5 Vendor Experiment)

In your git checkout ($GOPATH/src/, run:

   govendor sync

This command should download the appropiate dependencies.

Once all that is setup, you should be able to run go build and get a working executable named wercker.

Once you've got a working Docker environment, running

  ./wercker build

should go through the entire build and testing process.

Note: this is the bare minimum to build and contribute to the code base. If you do not have a local Docker environment you will not be able to run and test wercker properly. You can follow this guide to install Docker on your machine.

Reporting Bugs

If you are experiencing bugs running wercker locally, please create an issue containing the following:

  • Which OS are you using?
  • Which Docker environment are you using? (Boot2docker, custom, etc)
  • Create a gist containing the following information:
    • The entire log when running wercker with the --debug log. (ie. wercker --debug build)
    • The wercker.yml file that causes the issues.

Please don't file any issue dealing with the usage of steps or unexpected behavior on hosted wercker.

If you are experiencing issues running builds or deploys on hosted wercker, please do the following:

Try running the build again to see if the error keeps occurring. If it does, turn on support for the application, and create an issue with the following information:
