Hello 👋
Saber is a tool that allows you to set-up a fully functioning LEMP stack using Docker 🐳
Just a single command to run and you're up and running!
saber new <app-domain>Each part of the LEMP stack is constructed in a separate container.
- NGINX
- PHP
- MySQL / MariaDB
When the application is set-up, you can access your new app by visiting it in your browser at http://your-site.test
A self-signed certificate can be assigned to the stack and uses the latest TLS security features.

Already done this? Skip ahead
DNSMasq is required so that Saber can function correctly. Here's a quick guide on getting it set-up. For a more detailed explanation, I recommend reading this article.
Install DNSMasq - this guide uses Brew
brew install dnsmasqOpen /usr/local/etc/dnsmasq.conf and anywhere in the file, add this line
address=/test/127.0.0.1Restart DNSMasq
brew services restart dnsmasqThen test it by running a dig command
dig my.awesome-website.test @127.0.0.1If you get a response like so, it works!
;; ANSWER SECTION:
my.awesome-website.test. 0 IN A 127.0.0.1Now you need to configure DNSMasq so it can control the way the DNS queries are performed.
sudo mkdir -p /etc/resolver
sudo tee /etc/resolver/test > /dev/null << EOF
nameserver 127.0.0.1
EOFNow any site with a .test TLD will resolve to your localhost
$ ping -c 5 saber.is.cool.test

Saber is heavily inspired by Valet. While not a complete fork, it's referenced a lot in the style and format of the code.
Saber was built purely as a fun project to be able to quickly spin up a development environment that can be customised exactly how it is needed to run.
Saber puts customisation ahead of speed when it comes to creating a new development environment. It might take longer to have to pull down Docker images and build them but it means you can have a server specced up to exactly as you want.
composer global require cjmellor/saber
if you want to run it on a per-project basis, run
cd /to/your/path
composer require cjmellor/saberNow run the install command to install Saber onto your system. You can choose a PHP and Database version on install, or just omit the options
saber installor with options
saber install --php=7.4 --db=mysql:8.0| Option | Default | Description |
|---|---|---|
| php | 7.3 | Just a version number (e.g. 5.6, 7.4) |
| db | mariadb:latest | db:version (e.g. mysql:5.7). latest also allowed |
saber new <app-domain>Creating an app will spin up the Dockerized LEMP stack.
Your application can be viewed at its domain of the same name (i.e. an app named saber-test will be viewable at http://saber-test.test). By default, the TLD will always be .test.
Currently, there is no way to change the TLD using Saber. This will change in future versions - PR's welcome!
The default credentials are:
| User | root |
| Pass | password |
| Database | default |
You can log in to the database as you normally would, via a command line or a GUI.
mysql -h 127.0.0.1 -P 3306 -u root -pWithout specifying otherwise, the application will be unsecure (http). If you want to run the app more securely, when creating your app, specify the --tls tag
saber new <app-domain> --tlsThis will create a self-signed certificate. Using the latest security protocols, the application can run on the latest version of TLS (1.3).
You can secure or unsecure an app by using the native commands available in Saber.
Each app created with Saber is configurable. You can enable or disable features that matter to you and how you want your environment setup.
When a new app is created, all the NGINX and PHP config is stored in a lemp folder within' the root
The NGINX config for each app can be found in:
lemp/nginx/config/conf.d/
The PHP config for each app can be found in:
lemp/php/config
Don't forget to restart the containers if you make changes to these files
Saber utilises the awesome H5BP project which keeps the application secure and up-to-date with the latest fixes.
saber remove <app-domain>You can remove an app if you no longer require it.
This will remove the certificates, the PHP and NGINX configurations and the code folder.
saber use 7.3Using the use command you can switch PHP versions easily!
By default, Saber encourages you to use stable versions of PHP. You can overwrite this by supplying a --force option that will allow you to use other PHP versions.
Example:
saber use --force 5.6.40
saber use -f 7.4.0RC6-fpmsaber secure <app-domain>By default, apps aren't secure - they're running on HTTP. If you want your app to run over HTTPS you can run the secure command which will assign an SSL certificate to your app.
The SSL certificates are self-signed.
If you added an SSL on creation of your app, or you made a mistake and want to start over, you can perform the reverse of this and remove an SSL certificate
saber unsecure <app-domain>The images used to build your environment are often updated by the maintainers of the image, resulting in newer versions and secrity fixes. Normally to upgrade a version of PHP or MySQL it would take many hours to upgrade it manually or lots of tedious tickets or phone calls with your hosting provider.
Saber will pull down the newest versions of the images you want to upgrade and rebuild the containers.
saber upgradeRun the upgrade command, and you'll be presented with a list of images stored locally on your machine
Select images to upgrade. Select multiple by seperating with a commar, example: 1,3
[0] composer:latest
[1] php:7.2-fpm-alpine
[2] php:7.3-fpm-alpine
[3] nginx:alpine
[4] mariadb:latest
>Choose the image you want to update by typing the corrosponding number and the image will be pulled down and the containers will be rebuilt.
If you want update multiple images, select the image number in a commar separated value, e.g.
> 2,3,4and those images will be updated.
Images cannot be updated simultaneously, they will be pulled one at a time before been rebuilt
Not your cup of tea? That's okay, you can uninstall Saber from your machine - but you will lose everything!
saber uninstall🚨 I encourage you to help me make this tool even more useful! I will be adding more features to it over time.
🐛 There are bound to be some bugs hiding away that have not been counted for - help me get rid of them by creating an issue.
