DevOps Tools: Container Management
DevOps tools fit a lot of categories under one umbrella, with many variations on the applications that make agile development more efficient. The most ubiquitous among these is container software, a large part of why cloud development has become more the norm for agile development, and less an emerging trend.
This is probably old news for most modern cloud developers, though. Chances are you already understand the virtues of containers, and have since moved on to the different ways to manage them. Even if you have a solution in place, there is always a way to improve. The following container management tools for DevOps present possibilities to that end, or perhaps confirmation if you were already considering a change.
Kubernetes is one of the most popular container management tools for a reason, as it offers proprietary polish behind its open-source license. After Google passed the rights to Linux and the Cloud Native Foundation back in 2015, Kubernetes became a poster child of sorts for the inevitable takeover of containers. The level of attention from Google and Linux helped spur its development—making it an industry leader among both cluster management software and DevOps tools, as well as the fastest-growing software in open-source history according to IBM.
- Its container orchestration mechanisms provide automated unit grouping in logical categories, which means better discovery and more efficiency with larger workloads.
- Since this is the same container management that Google uses, this DevOps tool has been put through the paces with billions upon billions of use cases. Its open-source status means countless test runs disseminated by millions over the years, and the knowledge base for the DevOps tool is everywhere on the Web. That’s to say nothing of participating giants like Amazon, Microsoft, and IBM, as well as countless other developers who have their own version of Kubernetes and their own extensive documentation.
- The scalability of Kubernetes makes it a good fit for both small and enterprise-level companies, but also for stabilized development operations that need to adapt quickly to a sudden influx.
- Self-healing mechanisms have fail-safes, restarts, notifications, and containers cease action on failed health checks. Kubernetes will also prioritize pods and self-adjust those of lower priority to try and get to the most important ones first.
If Kubernetes is the current poster child, Docker is the original. In fact, Kubernetes was created to work with Docker before it moved on shouldn’t deter developers from this mainstay of container management. Docker is still one of the most reliable ways to instill CI/CD without the overhead of virtualization. These are the main reasons Docker remains one of the best tools for DevOps:
- Docker is an agent of microservice architecture, a great way to push agility, independence, and continuous deployment by removing code dependencies. Developers can keep working in their comfort zones without losing momentum over compatibility.
- ‘Swarm’ mode uses the power of hardware or virtual machines for multi-host networking, allowing devs to leverage the best of hardware, VMs, and containers at once. This allows tighter security, focused cluster management, and more practical control of the Docker API.
- Docker Compose CLI lets developers launch applications and their tests at will, with multi-container applications fired from a single command in any environment.
- Docker Container Registry integrates with most other DevOps tools like GitLab to instill container management.
Along with the aforementioned household names, Hashicorp’s Nomad makes its mark as the up-and-coming contender vying for its spot among giants. Nomad’s true value is as a lightweight and streamlined alternative to the feature-rich platforms above, though not at the cost of modernization. The momentum of its active development community adds to its growing sentiment as a viable alternative.
- Extensible task drivers allow Nomad to run any type of application through resource isolation. The platform is flexible enough to facilitate any workload on Windows, Linux, BSD, or Mac OSx, including legacy and batch applications.
- Nomad presents an optimistically concurrent scaling apparatus that was built into its core from the very beginning of development. As a result, the platform can handle enormous and rapidly growing workloads easily, and with consistent availability.
- Nomad runs on a single binary architecture that promotes operational simplicity and better control over resource allocation. It also requires no external services to manage its storage, eliminating the inherent complexity of some of its peers.
- Nomad Jobs combine multiple task groups with simple instructions written in their Hashicorp Configuration Language (HCL). The flexibility of task drivers can provide complete solutions for a given goal with just a few lines of text.
