Naming convention for Images

Since we work with lots of images and container daily as time goes and container and images start piling up, we need to come up with a convenient way to name such objects inside Docker.

Here's a suggested naming convention for images:

[VENDOR]-[MAIN SOFTWARE]-[OPERATING SYSTEM]:[TAG]

XXX-YYY-ZZZZ:N.N.N.N-N.N.N.N = [3-3-4]:[7-7]

  Where XXX: Are 3 letters from the image software vendor.

  YYY: Are 3 letters from the image main software.

  XXXX: Are 4 letters from the OS used to build the image.

Examples:

php-php-ubun:7.0-18.04 = Is PHP 7.0 from the vendor PHP.net running over Ubuntu 18.04 LTS.

mys-mys-fedo:8.0-30 = MySQL 8.0 from vendor MySQL over Fedora 30.

mic-sql-ws16:17.0-2016 = SQL Server 17.0 or 2016 from vendor Microsoft and running over Windows Server 2016.

Naming convention for Containers

[VENDOR]-[MAIN SOFTWARE]-[OPERATING SYSTEM]_[VERSION]

XXX-YYY-ZZZZ_N.N.N.N-N.N.N.N = [3-3-4]_[7-7]

Examples:

atl-jir-cent_8.2.3-8 = Jira 8.2.3 from Atlassian running over Centos 8 OS.

asf-kaf-ubun_2.2.0-18.04 = Kafka 2.2.0 from Apache Software Foundation running over Ubuntu 18.04 LTS.

As you can see it offers a more predictable way to name images and containers and offers a more organized way to display such names on console to commands such as docker ps.
