It is written in Rust and is designed to be lightweight, easy to set up, and run on various platforms. Vaultwarden is an alternative backend for the password manager Bitwarden, and while it does not implement the same feature set as the Bitwarden server, its setup is much simpler. Vaultwarden is a great option for small businesses because it is lightweight and runs well on devices with limited resources, such as Raspberry Pi and Synology NAS. It is also easy to set up and use, making it a great choice for businesses that do not have dedicated IT staff. Additionally, Vaultwarden is open-source, which means that businesses can customize it to meet their specific needs.
Jenkins is a platform for creating a Continuous Integration/Continuous Delivery (CI/CD) environment. It is written in Java and provides support for various version control tools such as Git, running Bash scripts and Windows batch files, building Ant and Apache Maven-based projects, and more. Jenkins helps build, test, and continually deploy software. It is an open-source system and one of the leading automation servers. Jenkins requires scripting some automation steps, but it provides a fast and robust way to systematize the software development lifecycle. The program runs web containers and plugins, such as Apache Tomcat, and helps manage lifecycle and access rights requests. Over 1700 plugins for Jenkins enrich the software integration, automation, and delivery processes and provide a customizable environment. Jenkins is used for the whole software delivery pipeline, including deployment.

The Podman, a container management tool, provides a flexible and user-friendly alternative to traditional container orchestration systems.
Containerization has revolutionized software deployment, and Docker Swarm provides a powerful solution for orchestrating and managing containerized applications. In this guide, we will take you through the step-by-step process of setting up and effectively using Docker Swarm on three virtual machines, and then extend it to include a load balancing proxy using Nginx. By the end of this tutorial, you’ll be equipped with the knowledge to harness the benefits of container orchestration and load balancing for your projects.
Docker networks are virtual networks created by Docker to enable communication between Docker containers, allowing them to connect to and communicate with each other or to non-Docker workloads. Containers inside the Docker network can talk to each other by sharing packets of information, and each container sees a network interface with an IP address, a gateway, a routing table, DNS services, and other networking details. By default, the container gets an IP address for every Docker network it attaches to, and when a container starts, it can only attach to a single network, using the –network flag. However, you can connect a running container to multiple networks using the docker network connect command.
In today’s ever-evolving IT landscape, the need for self-service automation and precise scheduling has become significant. Enter Rundeck and Ansible, two formidable tools that empower organizations to speed up their infrastructure management. When combined with the containerization capabilities of Podman and the orchestration provided by Podman-Compose, you can create a robust automation environment that not only simplifies self-service tasks but also enables precise scheduling.
Docker has revolutionized the way we build, ship, and run applications by containerizing them. One critical component of a well-managed container ecosystem is a Docker registry. While Docker Hub is a popular choice for hosting container images, there are compelling reasons to set up an in-house Docker registry. In this guide, we will walk you through the steps to configure and host your own Docker registry, ensuring control, security, and efficiency in your containerized environment.
In the dynamic world of containerization and orchestration, developers and IT professionals continually seek tools that streamline the deployment and management of containerized applications. While Docker Compose has long been the go-to solution for orchestrating containers, its dependency on the Docker daemon can be limiting in certain environments. Enter Podman-Compose, a powerful alternative that offers greater flexibility and security while maintaining compatibility with Docker Compose syntax. In this blog post, we’ll look into Podman-Compose, exploring its key features and demonstrating how it can simplify your container orchestration tasks.
Testing Ansible roles is a crucial step in ensuring the reliability and correctness of your infrastructure automation. Among the various tools available for this purpose, Molecule stands out as a versatile framework for testing Ansible roles. When coupled with Podman, a containerization tool similar to Docker, it provides a seamless and efficient environment for testing Ansible roles on Debian Linux. In this blog post, we will explore the process of setting up Molecule with Podman on Debian Linux.
In today’s rapidly evolving world of containerization and micro services, Docker has emerged as a powerhouse, providing tools to simplify the deployment and management of applications. Among its arsenal are Docker Compose and Docker Swarm, two distinct tools that address different aspects of container orchestration. In this article, we’ll dive into the nuances of Docker Compose and Docker Swarm, highlighting their features, use cases, and how to make the right choice for your deployment needs.
Continue reading “Docker Compose vs. Docker Swarm: Choosing the Right Orchestration Tool”Docker has revolutionized the way applications are deployed, offering portability and scalability like never before. One crucial aspect of Docker is volume management, which ensures data persistence and sharing between containers. In this article, we’ll dive a bit into the world of Docker volumes, explore their types, and I will provide practical examples of how to effectively manage them.
