The main purposes of the Build Tools project are to:
Ease the creation of new projects making use of an external Git provider, a Continuous Integration service, and Pantheon.
This is primarily done through the build:project:create commands, which scaffolds new projects from a template repository and performs one-time setup, such as configuring SSH keys and environment variables, needed to connect an external Git provider and CI service with Pantheon. For detailed set-up instructions, see the Terminus Build Tools Guide. To use your own template repository see Customization.
Add additional commands to Terminus to make tasks common in an automated CI workflow easier. See Commands and Build Tools Command Examples for details.
- If you are using Terminus 3, you must use the Build Tools
3.xrelease. - If you are using Terminus 2, you must use the Build Tools
2.xrelease.
PHP 7.2 or greater is recommended.
terminus self:plugin:install terminus-build-tools-plugin
mkdir -p ~/.terminus/plugins
composer create-project --no-dev -d ~/.terminus/plugins pantheon-systems/terminus-build-tools-plugin:^2
The Terminus Build Tools plugin should be installed without dev dependencies. If you install the plugin with a different method, such as cloning this source repository, use composer install --no-dev to download the project dependencies.
It is recommended that you use one of the provided example projects as a template when creating a new project. All of the example projects use Terminus 2 and Build Tools 2.x.
The default template repositories are each assigned an abbreviation, as shown below:
More details about these template repositories see Template Repositories in this document or visit the links above.
You can get started with one of these examples by using the build:project:create command:
$ terminus build:project:create --team='My Agency Name' wp my-site
This command will create:
- A Pantheon site
- A GitHub repository
- A CircleCI test configuration
It will prompt you for the credentials it needs to create these assets. While GitHub and CircleCI are the defaults, other providers are supported as well. See available services for details.
Note: After running this command, if you get an error "There are no commands defined in the "build:project" namespace", then you may need to install this Terminus plugin first as described in Requirements, above.
Note: It is important to specify the name of your agency organization via the --team option. If you do not do this, then your new site will be associated with your user and will not have the capability to create multidev environments.
The build:project:create command supports services in the following combination:
| Git Host | CI Service |
|---|---|
| GitHub | CircleCI |
| GitHub | Github Actions |
| GitLab | GitLabCI |
| BitBucket | CircleCI |
Note: if using Github Actions, token should have the "workflow" scope.
$ terminus build:project:create --git=gitlab --team='My Agency Name' wp my-site
$ terminus build:project:create --git=bitbucket --team='My Agency Name' wp my-site
$ terminus build:project:create --ci=githubactions --team='My Agency Name' wp my-site
Bitbucket
- Composer Lock Updater isn't working quite yet.

You may easily create your own project template by forking one of the Pantheon maintained examples (linked above) and customizing it to suit your needs. To use a custom starter, register your project on Packagist, and then use the projects org/name with the build:project:create command:
$ terminus build:project:create --team='My Agency Name' my-project/my-starter my-site
See Starter Site Shortcuts below for instructions on defining your own shortcuts for your starter projects.
Configuration values for the Terminus Build Tools Plugin may be stored in your Terminus Configuration file, located at ~/.terminus/config.yml. This is especially useful for agencies who would like every site created within their Pantheon team.
Terminus configuration is based on the Robo PHP configuration system. Default option values for Terminus commands can be defined in the same way as other Robo applications. For example, the options for the command build:project:create are stored in the section command: > build: > project: > create: > options:. The example below provides default values for the --admin-password and --team options.
command:
build:
project:
create:
options:
admin-password: secret-secret
team: My Pantheon Org
The GitLab URL used by Build Tools can be defined by updating the build-tools:provider:git:gitlab:url configuration value, as demonstrated by the example below. Note that you will need to replace hostname with the actual GitLab instance hostname.
build-tools:
provider:
git:
gitlab:
url: hostname
If you often create sites based on certain common starter sites, you may also use your Terminus configuration file to define custom starter site shortcuts. The example below defines shortcuts for the Lightning and Contenta distributions:
command:
build:
project:
create:
shortcuts:
contenta: pantheon-systems/example-drops-8-composer:dev-contenta
Note that the project name follows the standard defined by Composer: org-name / project-name : dev- branch-name.
To customize this for a specific project:
- Define necessary environment variables within your CI provider:
- TERMINUS_SITE: The name of the Pantheon site that will be used in testing.
- TERMINUS_TOKEN: A Terminus OAuth token that has write access to the terminus site specified by TERMINUS_SITE.
- GIT_EMAIL: Used to configure the git user’s email address for commits we make.
- Customize
dependencies:as needed to install additional tools. - Replace example
test:section with commands to run your tests. - Add a
build-assetsscript to your composer.json file.
Note that using a single environment for each PR means that it is not possible to run multiple tests against the same PR at the same time. Currently, no effort is made to cancel running tests when a new one is kicked off; if the concurrent build is not cancelled before a new commit is pushed to the PR branch, then the two tests could potentially conflict with each other. If support for parallel tests on the same PR is desired, then it is possible to eliminate PR environments, and make all tests run in their own independent CI environment. To do this, configure your CI provider by adding the following environment variable:
TERMINUS_ENV: $CI_LABEL
To use this tool on a Pantheon site that does not have multidev environments support, it is possible to run all tests against the dev environment. If this is done, then it is not possible to run multiple tests at the same time. To use the dev environment, configure your CI provider by adding the following environment variable:
TERMINUS_ENV: dev
** IMPORTANT NOTE: ** If you initially set up your site using terminus build:project:create, and you do not use the --team option, or the team you specify is not an Agency organization, then your configuration will automatically be set up to use only the dev environment. If you later add multidev capabilities to your site, you will need to edit the environment variables in your CI configuration and delete the entry for TERMINUS_ENV.
The examples below show how some of the other build:env: commands are used within test scripts. It is not usually necessary to run any of these commands directly; they may be of interest if you are customizing or building your own test scripts.
terminus build:env:create my-pantheon-site.dev ci-1234
This command will commit the generated artifacts to a new branch and then create the requested multidev environment for use in testing.
terminus build:env:push my-pantheon-site.dev
This command will commit the generated artifacts to an existing multidev environment, or to the dev environment.
terminus build:env:merge my-pantheon-site.ci-1234
terminus build:env:delete my-pantheon-site '^ci-' --keep=2 --delete-branch
terminus build:env:list
terminus build:comment:add:pr --pr_number=123 --message="Behat tests passed!"
Run terminus list build for a complete list of available commands. Use terminus help <command> to get help on one command.
In addition to the Terminus Build Tools Plugin, Pantheon maintains template repositories for:
Each repository includes an opinionated set of workflows and deployment scripts. These templates are meant to be a one-time starting point for new projects and customized as needed. Improvements made over time must be manually applied to existing projects. These are examples, not frameworks.
Pantheon maintains a Build Tools CI Dockerfile, which is deployed to quay.io, for use in Continuous Integration environments. It contains common Pantheon tools, such as Terminus and the Terminus Build Tools plugin. The deployed image tags follow semantic versioning.
Quicksilver pushback is a project that makes use of Pantheon's Quicksilver Webhooks to apply code commits made on Pantheon to an external Git provider.
