Continuum is a lightweight continuous integration tool: no web interface, no scheduler. It runs on command line and is triggered by cron.

You can install it using PIP, typing pip install continuum_ci. This will install the continuum script in you PATH. You may also download the archive, expand it and type in the created directory python setup.py install.

While calling continuum, you must pass the configuration file name on the command line:

continuum config.yml

Configuration is in YAML format:

directory:  /tmp
email:
  smtp_host: smtp.foo.com
  smtp_user: username
  smtp_pass: password
  recipient: [email protected]
  sender:    [email protected]
  success:   false

modules:
  continuum:
    url:     https://github.com/c4s4/continuum.git
    command: |
      set -e
      virtualenv env --no-site-packages
      . env/bin/activate
      pip install -r etc/requirements.txt
      bee test
  module2:
    url:     https://github.com/foo/bar.git
    command: |
      set -e
      commands to run the test

The first part indicates:

• directory: the directory where modules will be checked out. Currently only GIT projects are supported.
• email: put ~ if you don't want any email.

If you wait to receive email reports, provide following fields:

• smtp_host: the hostname of your SMTP server.
• smtp_user: the username to access SMTP server.
• smtp_pass: the password to access SMTP server.
• recipient: the email of the recipient of the build report.
• sender: the email address if the sender of the report.
• success: tells if continuum should send an email on success. If false, it will only send an email on build error.

If smtp_host, smtp_user and smtp_pass are not set, their value is extracted from MAIL_SMTP, MAIL_USERNAME and MAIL_PASSWORD environment variables.

The second one is the list of modules, with, for each module:

• url: the URL of the module that GIT will use to get the sources.
• command: the command to run tests, must return 0 on success and a different value on error (as any Unix script should). Note the pipe character (that is |) after the command: declaration.

The most important thing to remember about editting YAML is that Tab characters are forbidden (and should be replaced with spaces to properly indent). Please see YAML specification (at http://www.yaml.org/spec/1.2/spec.html) for more details.

This script is triggered using cron, with as configuration as follows (in file /etc/crontab):

# run continuum at 4 every night
0   4 * * *  me    continuum /home/me/etc/continuum.yml

Please make sure that the PATH to continuum is defined in your cron configuration. You may add the right PATH at the beginning of your crontab file as following:

PATH=/path/to/continuum:/rest/of/my/path

# run continuum at 4 every night
0   4 * * *  me    continuum /home/me/etc/continuum.yml
