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.

In certain situations, such as when administering a remote server running Xubuntu, it can be useful to be able to lock the screen remotely. This can help ensure the security and privacy of the system, especially when multiple users have access to the server. In this blog post, we will walk you through the process of remotely locking the Xubuntu screen from SSH.

Prerequisites

To follow this guide, you’ll need the following:

Cloning multiple GitHub repositories with different deployment keys can be useful when you need to access multiple repositories using different SSH keys associated with the same GitHub account. This guide provides step-by-step instructions on how to clone multiple repositories with different deployment keys while using the same username. By following these steps, you can streamline your workflow and manage multiple repositories more efficiently.

Step 1: Generate Deployment Keys

To begin, generate a deployment key for each repository you want to clone. Use the ssh-keygen command on your local machine to create a unique key for each repository.

If you’re using Ubuntu as your operating system on a MacBook and have recently updated the kernel, you might encounter issues with your camera not working. This problem can be resolved by reinstalling the necessary drivers. We will guide you through the steps to fix the camera problem and get it up and running again.

Step 1: Open Terminal

If you’re working on a Mac and using Git, you might run into an issue where Git won’t replace a folder that has had a change in case. For example, if you have a folder called “Article” and you change it to “article”, Git might not recognize the change and won’t replace the old folder with the new one.

Fortunately, there is a solution to this problem. You can configure Git to not ignore case sensitivity by running the following command:

Cryptomator is a popular open-source encryption software that allows users to secure their files and folders by creating encrypted vaults. However, like any software, Cryptomator may encounter occasional issues. One common problem on macOS is the inability to unlock a vault due to MacFuse hang. In this article, we will guide you through the process of reloading the MacFuse kernel extension to resolve this issue and regain access to your encrypted vault.
