.asf.yaml is a branch-specific YAML configuration file that a project may create (using a text editor of your choice) and put in the root of a git repository to control various features such as
It operates on a per-branch basis, meaning you can have different settings for different branches, and only those with an active
.asf.yaml file will kick off a feature. Metadata settings (repo settings, features, labels,) are not branch-dependent, and should exist in the main (default) branch.
--in your .asf.yaml file, it will cause parsing to fail.
whoamimatching the branch name will run.
.asf.yaml, make sure that you have discussed what you propose with the entire project first, and have understood what the configuration changes will do to your (and the team's) workflow and project resources.
Projects can set their notification targets for commits and github issues/PRs via .asf.yaml:
Setting up notification schemes via .asf.yaml can only happen in the master/trunk or default branch of a repository, and each configuration change will cause your project's private@ list to receive a notification of the change, for review purposes.
If you wish to take a look at the default (old style) configuration for a repository, please visit
https://gitbox.apache.org/schemes.cgi?$repository-name-here , for instance https://gitbox.apache.org/schemes.cgi?lucene-solr
PRs and issues can be divided into sub categories, if a project wishes to split up the open/close emails and the comments/code review parts.
For instance, if a project wants new PRs to send an email to dev@foo, but want any comments on that PR to go to issues@foo, they can employ the following configuration:
Likewise, issues can be split into issues_status and
issues_comment for sending issue emails to the appropriate targets.
The hierarchy for determining the right mail target for an action is:
You can use the file to enable Jira notifications that will fire when an issue or a pull request has a ticket in its title, such as
"[TICKET-1234] Improve foo bar".
Options can be a set of one or more the following:
comment: Add the PR/issue event as a comment in the referenced Jira ticket.
worklog: Add the event as a worklog entry instead of a comment in the referenced Jira ticket.
label: Add a 'pull-request-available' label to referenced tickets.
link: Add a link to the GitHub PR/issue when it's opened to the referenced Jira ticket.
Concatenate the options you want to use as a string list, like this:

.asf.yaml file in a git repository manages web site deployment.
NOTE : Web site staging and publishing features are applied using the repository in which you have specified staging and publishing . Thus, only specify it within the repository that contains your web site material, or you could end up just seeing a list of source code files from your source repository.
A basic staging and publishing profile to get you started could be:
This configuration enables a staging (live preview) web site at yourproject.staged.apache.org using the
branch of your repository, as well as deploying the
asf-site branch of the repository to your main web site at yourproject.apache.org. Details below:
To enable staging (live preview) of your project's web site, add a
staging entry to the site repository's
As an example, take the imaginary
yourproject-website.git with an
.asf.yaml file containing the following entry:
This would stage the current branch at https://yourproject-beta.staged.apache.org/ . You can add multiple staging profiles and thus multiple branches staged for preview. This can be helpful when doing A/B evaluations of website contents and features.
You can also omit the profile value, and stage directly at https://yourproject.staged.apache.org/ . ( "~" (tilde) means "no value" in YAML):
Set a protection on multi-tenancy by specifying a
whoami setting. If the setting's value does not match the current branch, no checkout/update will happen. You can have this in the .asf.yaml file on the
When you clone that branch to a new branch like
asf-staging-copy, the staging web site server will notice that the value of
whoami does not match
asf-staging-copy, and will ignore that branch until the
whoami is updated to match it.
Note: if you have previously used gitwcsub for web site publishing, your first publish action using
.asf.yaml will cause any existing gitwcsub or svnwcsub subscription to stop working. This ensures that there are no race conditions or "repository fights" going on when you publish.
To publish a branch to your project web site sub-domain (yourproject.apache.org), set up a configuration block called
publish in your
.asf.yaml file. Enable branch-protection through the
whoami parameter, like so:
If, for whatever reason, a project wishes to revert back to gitwcsub for publishing, remove the publish feature in your .asf.yaml file.
By default, web sites will be published at $project.apache.org where $project is the sub-domain name of your project, as determined by the repository name.
Some projects have special domains, like openoffice.org, and may publish to these by specifying a
hostname attribute in the publish configuration block:
NOTE: You cannot specify your $project.apache.org hostname with this setting. It has to be inferred to prevent abuse. Also, please do not abuse this feature, thanks!
To publish to a sub-directory of the web site URL, specify a subdir value. Such checkouts can be useful for sub-projects.
For instance, if httpd wished to check out a repository into
httpd.apache.org/subproject, they could use the following configuration:
The staging and deployment servers support both the
content/ sub-dir and the pelican build
output/ sub-dir as the root directory for the web site. Thus, the website root can be any of:
content/directory at the root of the branch
output/directory at the root of the branch
Projects can update their GitHub metadata (repository description, homepage and labels) via
.asf.yaml like this:
NOTE : Metadata changes will only apply if you specify them in the .asf.yaml file in the
master (or otherwise default) branch of a repository
Projects can enable/disable GitHub repository features to provide better support.
Projects can enable/disable the "merge PR" button in the GitHub UI and configure which actions to allow by adding the following configuration (or derivatives thereof):
Projects can enable/update GitHub Pages settings, using GitHub for website publishing, by specifying which branch (and optional path) to publish:
The ghp_branch setting can ONLY be either
ghp_path setting is ONLY valid if
ghp_branch is set to
master, and MUST be either null (~) or
Projects can enable branch protection in their repos, including most of the sub-level protection features, such as 'require status checks to pass before merging' , 'approval by at least $n people' , 'require pull request reviews' and more.
NB (1): Enabling any of the above checks overrides what may have been set previously, so you'll need to add all the existing checks to your .asf.yaml to reproduce those previously set manually by Infra.
NB (2): If you need to remove a required check in order to push a change to .asf.yaml, you will need to create an Infra Jira ticket with a request to have the check manually removed.
All protected branches in the YAML must be dictionary entries. Thus, if you only want to disable force push from a branch, you can construct a fake dictionary like so:
Branches that are not in the YAML or are not dictionary entries will not be protected.
More info on this can be found on the PR1678 that implemented this cool feature.
For projects using Jenkins for CI testing, PRs are generally only built when a committer submits one. Projects MAY choose to designate a GitHub person as a 'safe/reliable' person using the jenkins/github_whitelist feature:
The GitHub IDs listed here would have access to start builds based on PRs in addition to the committers on the project.
Projects can build their websites automatically using Jekyll. This solution allows the use of custom plugins. Content generated this way can be staged or pushed directly to production when it is used in conjunction with the
publish configuration options.
Optionally, a named output directory may be specified as
outputdir. If a value is not specified for this property, it defaults to '
_config.yamlfile. It must stay as is and output the generated files into a
To set up an automatic build (as we did in the old Apache CMS system), add a
jekyll section to
Projects can automatically build web sites using the Pelican CMS System and even have the result either staged or pushed directly to production (with the addition of a
publish configuration, as seen above).
To set up an automatic build (much the way the old Apache CMS system works), add a
pelican section to
The above configuration generates the site using pelican and pushes only the created output to the asf-site branch. An example web site repository that uses the pelican auto-build feature is: https://github.com/apache/infrastructure-website.
Our Pelican builds support GFM (GitHub-Flavored Markdown), meaning you can edit web sites using the GitHub UI and instantly get a preview of your page before pushing it to the build/publish process.
GFM is enabled by default, but will default to standard markdown if you have PLUGINS defined in your pelicanconf.py file. To explicitly enable GFM along with other manually defined plugins, you may specify
pelican-gfm as a plugin, and it will be woven into the build.
Furthermore, you can build off one branch and publish to another using the
target parameter, as seen above. If you leave this parameter out, the build process pushes the generated site to the same branch it built from (in the
output/ base directory).
Pelican auto-builds support using different themes via the
theme argument to specify the directory that contains your theme. This is equivalent to the
-t switch in pelican:
You can build and publish your website at the same time by employing both the pelican and publish configurations in your .asf.yaml file:
The configuration snippet above would, when present in both master and asf-site branches, build the web site from the master branch, then push the result to the asf-site branch and publish that branch as your project web site.
Likewise, you can employ auto-build-and-stage:
This would build your site from the master branch, push the result to the asf-site branch and then stage that result on your staging domain.
These features have not been implemented in production yet, but are documented here for future use.
