Getting started with Lando, Docker, and Drupal

As a Drupal developer, I need to run local copies of a bunch of different web sites. I might switch between a few clients any given day, and I might spin up another site to test a patch to Drupal core or to a contributed module.

I want to keep this short, so I will not go into all the different methods I have tried for setting up local sites. Let’s just say that all the Cool Kids have been using Docker for a few years now, and I have been slow to join the party.

The good news is that it is now really easy to get started with Docker, thanks to the Lando project. This post is the first in a series of short tutorials on using Docker and Lando to set up a local Drupal site. The immediate goal is to get to the Drupal installation screen.

System requirements

Sorry, this is only going to work if you have a fairly new computer. According to the Lando documentation you will need one of

  • macOS 10.10+
  • Windows 10 Pro+ (or equivalent) with Hyper-V running
  • Linux (with kernel version 4.x or higher)

So far, I have tested only with macOS 10.13 (High Sierra).

It is not strictly a requirement, but if you are not comfortable using the command line, then this tutorial is probably not for you.

Install Docker and Lando

Head over to the Lando releases on GitHub and download the latest package for your OS.

Run the installer. At least on a Mac, this installs Lando along with Docker for Mac. You can also install Docker first.

I wanted to make sure I had the latest versions for this post, so I

  • Installed the latest stable version of Docker for Mac (17.12.0-ce-mac55 (Version 18.03.0-ce-mac60 (23751)))
  • Reset Docker for Mac (Preferences, Reset, “Reset to factory defaults”)
  • Installed the latest version of Lando (v3.0.0-beta.39)
  • During installation, chose the “Custom” option to install just Lando, not Docker

Download Drupal

There are a lot of ways to get the Drupal codebase. For this tutorial, let’s follow the official instructions: Installing Drupal 8. (See “Step 1: Get the Code”.) From Download & Extend follow the link to the release page for the latest version and download the tarball. As of this writing, the latest version is 8.5.1. I choose to save the tarball in /tmp. If you save it somewhere else or get a newer version, then adjust the instructions in the next section.

Extract Drupal

Open up a terminal window. The following commands extract the tarball, creating the directorySites/drupal-lando/ inside your home directory. (I assume you already have the Sites/ directory.)

cd Sites
tar xzf /tmp/drupal-8.5.1.tar.gz
mv drupal-8.5.1 drupal-lando
cd drupal-lando

Initialize Lando

Still working in the terminal window, let Lando create a minimal configuration file for you:

lando init --recipe drupal8 --webroot=. --name="drupal-lando"

You can also run lando init interactively. I give the command this way to make sure that it is reproducible.

This produces the following YAML file .lando.yml:

name: drupal-lando
recipe: drupal8
config:
webroot: .

If you prefer, you can skip lando init and just copy and paste that file directly.

What does this command do?

If you run lando with no arguments, it will show you the available sub-commands. The one thing I do not like is that you have to be careful to get help for a sub-command:

lando init -- --help

You can use the short form -h instead of --help, but other variants will not work. For example, lando --help init is the same as lando --help, and lando init --help acts like lando init (running the sub-command instead of showing the help text).

Start your (Docker) engine!

In the terminal window, type

lando start

If it goes smoothly, Lando should start Docker, create two containers, and leave you with instructions something like this:

BOOMSHAKALAKA!!!Your app has started up correctly.
Here are some vitals:
NAME drupal-lando
LOCATION /Users/bfisher/Sites/drupal-lando
SERVICES appserver, database
APPSERVER URLS https://localhost:32772
http://localhost:32773
http://drupal-lando.lndo.site
https://drupal-lando.lndo.site

If it does not go smoothly, try quitting and restarting Docker.

Install Drupal

If everything worked, then you can visit your local site at http://drupal-lando.lndo.site. (You can also use the HTTPS version, although your browser should warn you about the untrusted SSL certificate.)

Since you are starting with an empty database, you will be redirected to http://drupal-lando.lndo.site/core/install.php:

Drupal installation screen

You can accept the defaults on the first couple of screens, but when you get to the database configuration, see what lando info has to say:

lando info
...
"database": {
"urls": [],
"type": "mysql",
"version": "latest",
"hostnames": [
"database",
"database.drupallando.internal"
],
"creds": {
"user": "drupal8",
"password": "drupal8",
"database": "drupal8"
},
"internal_connection": {
"host": "database",
"port": 3306
},
"external_connection": {
"host": "localhost",
"port": "32769"
},
"config": {
"confd": "/Users/bfisher/.lando/services/config/drupal8/mysql"
}
}
}

So enter “drupal8” as the database name, database username, and database password. Then open up the “Advanced options” and enter “database” for the host.

Drupal database configuration

In a minute or two you should have a clean Drupal site, ready to go!
