Here’s a quick thing I did for a couple of my colleagues, to demo writing a Lando environment from scratch. I grabbed the latest copy of Omeka-S and unzipped the file, then wrote the following .lando.yml file
name: omeka-s
recipe: lamp config: php: '7.3'
webroot: .
database: mysql:5.7
xdebug: false
And then I modified the config/database.ini file to use the default DB credentials used by Lando:
user = "lamp"
password = "lamp"
dbname = "lamp"
host = "database"
And then I ran lando start
and followed along with the rest of the Omeka S install guide.
Lando tells you the URL you need to visit after your site comes up.
