Warning: Altis v11 is no longer supported.

Local Server

Note: Local Server is a Docker-based environment. If you experience any issues running it consult the Local Chassis documentation for an alternative local environment.

The Local Server module providers a local development environment for Altis projects. It is built on a containerized architecture using Docker images and Docker Compose to provide drop-in replacements for most components of the Cloud infrastructure.


Windows Users: Consult the Windows setup documentation to set up a WSL environment before using Local Server.

Local Server uses Docker for containerization, therefore you must install the Docker runtime on your computer as a prerequisite. Download and install Docker for your OS at https://www.docker.com/get-started.

Once Docker is installed and running, you are ready to start the Local Server. Local Server uses the command line via the composer command.

Navigate your shell to your project's directory. You should already have installed Altis by running composer install or composer create-project but if not, do so now. See Creating A New Altis Project.

Experimental Features

You may find that file sharing performance or server response times are slower than you would like on Windows or MacOS. Local Server provides an experimental integration with Mutagen to resolve this.

See the Mutagen set up guide for detailed instructions on how to install and run it.

Starting the Local Server

To start the Local Server, run composer server. The first time you run this it will download all the necessary Docker images.

Once the initial download and install has completed, you should see the output:

Installed database.
WP Username:	admin
WP Password:	password
Startup completed.
To access your site visit: https://my-site.altis.dev/

Visiting your site's URL should now work. Visit /wp-admin/ and login with the username admin and password password to get started!

If the server does not start for any reason take a look at the troubleshooting guide

The subdomain used for the project can be configured via the modules.local-server.name setting:

	"extra": {
		"altis": {
			"modules": {
				"local-server": {
					"name": "my-project"

Multisite Subdomains: Currently on local-server subdomains aren't supported. Subsites must use subdirectories.
