Naming Conventions for Production Environments

Tue, 06 Jun 2023 06:47:00 +0700

Naming conventions are a crucial aspect of software development, providing consistency and clarity in various stages of the development lifecycle. In this article, we will explore the most common naming conventions for production environments, focusing on GitLab CI/CD, GitHub Actions, domain names, branch names, Docker Compose files, and Dockerfile names.

Naming	Common Convention
GitLab CI/CD Convention	prod
GitHub Actions Convention	prod
Domain Names	example.com
Branch Names	main/master
Docker Compose Files	docker-compose.yml
Dockerfile Names	Dockerfile

GitLab CI/CD Convention

In GitLab CI/CD, the convention for naming pipeline stages in production environments commonly involves using “prod” as the keyword. This convention ensures that pipeline stages are easily identifiable and aligned with the production deployment process.

Naming Conventions for Development Environments

Tue, 06 Jun 2023 06:45:00 +0700

Naming conventions play a vital role in software development environments, providing consistency and clarity throughout the development process. In this article, we will explore the most common naming conventions for development environments, covering GitLab CI/CD, GitHub Actions, domain names, branch names, Docker Compose files, and Dockerfile names.

Naming	Common Convention
GitLab CI/CD Convention	dev
GitHub Actions Convention	dev
Domain Names	dev.example.com
Branch Names	dev
Docker Compose Files	docker-compose.dev.yml
Dockerfile Names	Dockerfile.dev

GitLab CI/CD Convention

When working with GitLab CI/CD, the most common convention for naming pipeline stages in development environments is to use “dev” as the keyword. This convention ensures compatibility and alignment with GitLab CI/CD’s pipeline system.

Naming Conventions Stage vs Staging in Software Development

Tue, 06 Jun 2023 06:24:00 +0700

Naming conventions play a crucial role in software development, providing clarity and consistency in various aspects of the development lifecycle. When it comes to naming environments, such as staging, development, and production, there can be variations and debates around the usage of “stage” and “staging.” In this article, we’ll explore the differences and common practices surrounding these terms.

Defining Staging and Development Environments

Naming	Common Convention
GitLab CI/CD Convention	stage
GitHub Actions Convention	staging
Domain Names	staging.example.com
Branch Names	staging
Docker Compose Files	docker-compose.staging.yml
Dockerfile Names	Dockerfile.staging

Staging environments are integral to the software development process, serving as a dedicated space for testing and validation before deploying to production. In most cases, “staging” is commonly used as a noun to represent this environment. It refers to a stable and controlled testing area where developers can ensure their applications are functioning correctly and meet the required standards.

Configuring Apache in Docker Compose with Custom Log Settings and Size Limitation for Virtual Hosts

Sun, 21 May 2023 05:34:00 +0700

In this article, we will explore how to configure an Apache web server running in a Docker Compose environment with custom log settings and size limitation specifically for virtual host logs. We’ll cover the steps to set up the necessary volume mounts, configuration files, and log rotation to ensure that virtual host logs are limited in size. This will help you effectively manage disk space and maintain clean and manageable log files for your Apache server.

Deploying Docker Compose Production YAML on GitLab CI/CD

Wed, 17 May 2023 08:01:00 +0700

GitLab CI/CD provides powerful capabilities for automating the deployment of applications. Docker Compose is a popular tool for defining and managing multi-container Docker applications. In this blog post, we’ll explore how to deploy a Docker Compose production YAML file on GitLab CI/CD, even if the runner server and production server are not in the same location.

Prerequisites

Understanding of Docker Compose and GitLab CI/CD concepts.

Step 1: Setting up the Runner

To begin, set up a dedicated runner on the runner server. This runner will handle the execution of the deployment pipeline. Ensure that Docker is installed and properly configured on the runner server.

Using Fail2ban Inside Docker with NET_ADMIN Capability

Mon, 05 Oct 2020 09:55:49 +0700

Fail2ban is a popular intrusion prevention tool designed to protect servers from brute-force attacks and other malicious activities by monitoring log files and taking proactive measures to block suspicious IP addresses. When running Fail2ban inside a Docker container, there are some additional considerations to ensure proper functionality. In this article, we will explore how to configure and run Fail2ban inside a Docker container, including the need for the NET_ADMIN capability.

Fixing Too many open files in system Error in Apache Docker Container

Tue, 29 Sep 2020 17:18:26 +0700

If you encounter the “Too many open files in system” error in your Apache Docker container, it means that the system has reached the limit on the number of files it can open, and this is causing issues with Apache’s configuration. Here’s a step-by-step guide on how to resolve this problem.

1. Check the Current File Limit

First, you need to check the current file limit on your system to understand the magnitude of the issue. To do this, run the following command:

Docker Limit Quota Folder

Wed, 09 Sep 2020 12:08:41 +0700

In this article, we will discuss how to create and mount a limited quota folder using Docker. This can be useful when you want to restrict the amount of disk space a specific folder can use within a Docker container.

Prerequisites

Before we begin, make sure you have Docker installed on your system. You can download and install Docker from the official Docker website (https://www.docker.com/).

Troubleshooting Docker HTTPD SSL Log Not Appearing

Tue, 27 Mar 2018 12:32:35 +0700

When working with Docker containers and the Apache HTTP Server (httpd) in SSL mode, it is important to monitor and analyze the server logs for debugging and security purposes. However, in some cases, the SSL log might not show up as expected. This article aims to provide a solution to this problem by adding a custom log variable inside the virtual host configuration.

Problem

The SSL log is not being generated or displayed when running the Apache HTTP Server within a Docker container. This can make it difficult to track and analyze server activity and troubleshoot potential issues.

Troubleshooting Invalid IP Host Error in Docker Compose with HTTPD Container

Tue, 27 Mar 2018 12:31:29 +0700

When working with Docker Compose, you may encounter an “Invalid IP Host” error when configuring the HTTPD (Apache) container. This error often occurs when the container’s network configuration conflicts with the port mappings specified in the docker-compose.yml file. In this article, we will explore a common cause of this error and provide a solution by adjusting the network configuration using the net parameter.

Understanding the “Invalid IP Host” Error

The “Invalid IP Host” error message typically appears when running an HTTPD container in Docker Compose and indicates that the IP address provided for the container’s host is invalid or conflicting.
