+# SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed
+
+> Mon 14th December 2020 By David T. Sadler.
+
+One of the first things you do when creating a new Larvel application is run php artisan migrate to create the application database tables. However you may come across the below message.
+
+```shell
+$ php artisan migrate
+
+Illuminate\Database\QueryException
+
+  SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution (SQL: select * from information_schema.tables where table_schema = testsite and table_name = migrations and table_type = 'BASE TABLE')

+    675▕         // message to include the bindings with SQL, which will make this exception a
+    676▕         // lot more helpful to the developer instead of just the database's errors.
+    677▕         catch (Exception $e) {
+    678▕             throw new QueryException(
+    679▕                 $query, $this->prepareBindings($bindings), $e
+    680▕             );
+    681▕         }

+      Illuminate\Foundation\Console\Kernel::handle()
+```
+
+The cause of this issue is due to a change introduced to the .env.example file. This changed the environment variable DB_HOST from 127.0.0.1 to mysql. The reason for this change is to support [Laravel Sail](https://laravel.com/docs/8.x/sail) which is a Docker development environment for Laravel.
+
+The change means your Laravel application will try and connect to a database server with the hostname of mysql. Unless this exists then the application can't connect.
+
+To resolve the issue just change the value back to 127.0.0.1
+
+```shell
+DB_HOST=127.0.0.1
+```
