The objective of this repository is having a CaaS Containers as a Service to provide a "ready to use" container with the basic enviroment features to deploy a MariaDB database service under a lightweight Linux image for development stage requirements.
The container configuration is as Host Network on eth0 as Bridge network, thus it can be accessed through localhost:${PORT} by browsers but to connect with it or this with other services ${HOSTNAME}:${PORT} will be required.
- Built on the lightweight and secure Alpine 3.19 2024 release Linux distribution
- Multi-platform, supporting AMD4, ARMv6, ARMv7, ARM64
- Very small Docker image size (+/-280MB)
- Uses MariaDB 10.11 as default for the best performance, low CPU usage & memory footprint
- Service independency to connect from other container application to this database allocation
- Useful setting to run this service inside a cluster configuration
This project has not been tested on Windows OS neither I can use it to test it. So, I cannot bring much support on it.
Anyway, using this repository you will needed to find out your PC IP by login as an administrator user to set connection between containers.
C:\WINDOWS\system32>ipconfig /all
Windows IP Configuration
Host Name . . . . . . . . . . . . : 191.128.1.41

DNS Suffix Search List. . . . . . : scs.ad.cs.cmu.eduTake the first ip listed. Wordpress container will connect with database container using that IP.
Find out your IP on UNIX systems and take the first IP listed

Makefiles are often used to automate the process of building and compiling software on Unix-based systems as Linux and macOS.
To use Makefile on Windows I recommend to follow this post:
https://stackoverflow.com/questions/2532234/how-to-run-a-makefile-in-windows
Makefile recipies
$ make help
usage: make [target]
targets:
Makefile help shows this Makefile help message
Makefile hostname shows local machine hostname ip
Makefile fix-permission sets project directory permission
Makefile port-check shows .env port set availability on local machine
Makefile env checks if docker .env file exists
Makefile env-set sets the database enviroment file to build the container
Makefile ssh enters the database container shell
Makefile build builds the database container from Docker image
Makefile dev -- recipe has not usage in this project --
Makefile up starts the containers in the background and leaves them running
Makefile start starts existing containers for a service
Makefile stop stops running container without removing it
Makefile clear stops and removes the database container from Docker network destroying its data
Makefile destroy removes the database image from Docker - docker system and volume prune still required to be manually
Makefile sql-install installs into container database the init sql file from resources/database
Makefile sql-replace replaces container database with the latest sql backup file from resources/database
Makefile sql-backup creates / replace a sql backup file from container database in resources/database
Makefile repo-flush clears local git repository cache specially to update .gitignoreCreate a DOTENV file from .env.example and setup according to your project requirement the following variables
# Leave it empty if no need for sudo user to execute docker commands
DOCKER_USER=sudo
# Container data for docker-compose.yml
PROJECT_TITLE="MARIADB" # <- this name will be prompt for Makefile recipes
PROJECT_ABBR="mdb1" # <- part of the service image tag - useful inside a cluster
# Database container
PROJECT_DB_HOST="127.0.0.1" # <- for this project is not necessary
PROJECT_DB_PORT="8889" # <- port access container service on local machine
PROJECT_DB_CAAS="mariadb" # <- container as a service name to build service
PROJECT_DB_PATH="../resources/database/" # <- path where database backup or copy resides
PROJECT_DB_ROOT="7c4a8d09ca3762af61e595" # <- database root password
PROJECT_DB_NAME="mariadb" # <- database user
PROJECT_DB_USER="mariadb" # <- database name
PROJECT_DB_PASS="123456" # <- database user password
Exacute the following command to create the docker/.env file, required for building the container
$ make env-set
MARIADB docker-compose.yml .env file has been set.Checkout local machine ports availability
$ make port-check
Checking configuration for MARIADB container:
MARIADB > port:8880 is free to use.Build the container and start using it
$ make build up
