Learn how to configure GitLab Pages so you can help develop the feature.
Configuring GitLab Pages hostname
GitLab Pages needs a hostname or domain, as each different GitLab Pages site is accessed through a subdomain. You can set the GitLab Pages hostname:
Without wildcard, editing your hosts file
As /etc/hosts
don’t support wildcard hostnames, you must configure one entry
for GitLab Pages, and then one entry for each page site:
127.0.0.1 gdk.test # If you're using GDK
127.0.0.1 pages.gdk.test # Pages host
# Any namespace/group/user needs to be added
# as a subdomain to the pages host. This is because
# /etc/hosts doesn't accept wildcards
127.0.0.1 root.pages.gdk.test # for the root pages
With DNS wildcard alternatives
If instead of editing your /etc/hosts
you’d prefer to use a DNS wildcard, you can use:
Configuring GitLab Pages without GDK
Create a gitlab-pages.conf
in the root of the GitLab Pages site, like:
# Default port is 3010, but you can use any other
listen-http=:3010
# Your local GitLab Pages domain
pages-domain=pages.gdk.test
# Directory where the pages are stored
pages-root=shared/pages
# Show more information in the logs
log-verbose=true
To see more options you can check
internal/config/flags.go
or run gitlab-pages --help
.
Running GitLab Pages manually
For any changes in the code, you must run make
to build the app. It’s best to just always run
it before you start the app. It’s quick to build so don’t worry!
make && ./gitlab-pages -config=gitlab-pages.conf
Configuring GitLab Pages with GDK
In the following steps, $GDK_ROOT
is the directory where you cloned GDK.
- Set up the GDK hostname.
-
Add a GitLab Pages hostname to the
gdk.yml
:gitlab_pages: enabled: true # enable GitLab Pages to be managed by gdk port: 3010 # default port is 3010 host: pages.gdk.test # the GitLab Pages domain auto_update: true # if gdk must update GitLab Pages git verbose: true # show more information in the logs
Running GitLab Pages with GDK
After these configurations are set, GDK manages a GitLab Pages process, giving you access to it with commands like:
- Start:
gdk start gitlab-pages
- Stop:
gdk stop gitlab-pages
- Restart:
gdk restart gitlab-pages
- Tail logs:
gdk tail gitlab-pages
Running GitLab Pages manually
You can also build and start the app independently of GDK processes management.
For any changes in the code, you must run make
to build the app. It’s best to just always run
it before you start the app. It’s quick to build so don’t worry!
make && ./gitlab-pages -config=gitlab-pages.conf
Building GitLab Pages in FIPS mode
FIPS_MODE=1 make && ./gitlab-pages -config=gitlab-pages.conf
Creating GitLab Pages site
To build a GitLab Pages site locally you must
configure gitlab-runner
.
For more information, refer to the user manual.
Enabling access control
GitLab Pages support private sites. Private sites can be accessed only by users who have access to your GitLab project.
GitLab Pages access control is disabled by default. To enable it:
-
Enable the GitLab Pages access control in GitLab itself. You can do this in two ways:
-
If you’re not using GDK, edit
gitlab.yml
:# gitlab/config/gitlab.yml pages: access_control: true
-
If you’re using GDK, edit
gdk.yml
:# $GDK_ROOT/gdk.yml gitlab_pages: enabled: true access_control: true
-
- Restart GitLab (if running through the GDK, run
gdk restart
). Runninggdk reconfigure
overwrites the value ofaccess_control
inconfig/gitlab.yml
. - In your local GitLab instance, in the browser go to
http://gdk.test:3000/admin/applications
. - Create an Instance-wide OAuth application
with the
api
scope. -
Set the value of your
redirect-uri
to thepages-domain
authorization endpoint (for example,http://pages.gdk.test:3010/auth
). Theredirect-uri
must not contain any GitLab Pages site domain. -
Add the auth client configuration:
-
With GDK, in
gdk.yml
:gitlab_pages: enabled: true access_control: true auth_client_id: $CLIENT_ID # the OAuth application id created in http://gdk.test:3000/admin/applications auth_client_secret: $CLIENT_SECRET # the OAuth application secret created in http://gdk.test:3000/admin/applications
GDK generates random
auth_secret
and builds theauth_redirect_uri
based on GitLab Pages host configuration. -
Without GDK, in
gitlab-pages.conf
:## the following are only needed if you want to test auth for private projects auth-client-id=$CLIENT_ID # the OAuth application id created in http://gdk.test:3000/admin/applications auth-client-secret=$CLIENT_SECRET # the OAuth application secret created in http://gdk.test:3000/admin/applications auth-secret=$SOME_RANDOM_STRING # should be at least 32 bytes long auth-redirect-uri=http://pages.gdk.test:3010/auth # the authentication callback url for GitLab Pages
-
-
If running Pages inside the GDK, you can use GDK
protected_config_files
section undergdk
in yourgdk.yml
to avoid gettinggitlab-pages.conf
configuration rewritten:gdk: protected_config_files: - 'gitlab-pages/gitlab-pages.conf'
Enabling object storage
GitLab Pages support using object storage for storing artifacts, but object storage is disabled by default. You can enable it in the GDK:
-
Edit
gdk.yml
to enable the object storage in GitLab itself:# $GDK_ROOT/gdk.yml object_store: enabled: true
-
Reconfigure and restart GitLab by running the commands
gdk reconfigure
andgdk restart
.
For more information, refer to the GDK documentation.
Linting
# Run the linter locally
make lint
# Run linter and fix issues (if supported by the linter)
make format
Testing
To run tests, you can use these commands:
# This will run all of the tests in the codebase
make test
# Run a specfic test file
go test ./internal/serving/disk/
# Run a specific test in a file
go test ./internal/serving/disk/ -run TestDisk_ServeFileHTTP
# Run all unit tests except acceptance_test.go
go test ./... -short
# Run acceptance_test.go only
make acceptance
# Run specific acceptance tests
# We add `make` here because acceptance tests use the last binary that was compiled,
# so we want to have the latest changes in the build that is tested
make && go test ./ -run TestRedirect

Feature flags
Consider adding a feature flag for any non-trivial changes. Feature flags can make the release and rollback of these changes easier, avoiding incidents and downtime. To add a new feature flag to GitLab Pages:
- Create the feature flag in
internal/feature/feature.go
, which must be off by default. - Create an issue to track the feature flag using the
Feature flag
template. - Add the
~"feature flag"
label to any merge requests that handle feature flags.
For GitLab Pages, the feature flags are controlled by environment variables at a global level. A deployment at the service level is required to change the state of a feature flag. Example of a merge request enabling a GitLab Pages feature flag: Enforce GitLab Pages rate limits
