Server configuration

To start up, use a fresh installation of your favourite operating system. This could be any flavour of Linux, such as Ubuntu, Fedora or RHEL, to name a few.

Ports

Ensure that no other services are running on the ports specified below, especially those marked with an asterisk.

Port	Designated use
80*	NGINX http
443*	NGINX https
5432	PostgreSQL
5672	RabbitMQ
15672*	RabbitMQ management
11211	Memcached
6379	Redis
8000	Gunicorn
8001	Daphne
8081*	Redis Commander
60000 - 60031	Django development
61000 - 61031	React development

In the most common scenarios, 80 and 443 will be occupied on a fresh install of a server distribution like RHEL or Ubuntu Server. Stop Apache2 and prevent it from automatically starting up again.

[apps ~]$ sudo systemctl stop apache2
[apps ~]$ sudo systemctl disable apache2

Users

Set up a user other than root to build and manage the containers. Name him apps or whatever you fancy.

In case of a development setup, make user accounts for all your developers, one per person. Let’s assume you have two dev1 and dev2. They also get their own directories at /home/dev1/ and /home/dev2/.

[dev1 ~]$ whoami
dev1
[dev1 ~]$ pwd
/home/dev1

[dev2 ~]$ whoami
dev2
[dev2 ~]$ pwd
/home/dev2
