Open Source Linux DevOps Tools

From datacenter to cloud to edge, Rancher lets you deliver Kubernetes-as-a-Service. Rancher is a complete software stack for teams adopting containers. It addresses the operational and security challenges of managing multiple Kubernetes clusters, while providing DevOps teams with integrated tools for running containerized workloads. From datacenter to cloud to edge, Rancher's open source software lets you run Kubernetes everywhere. You don’t need to figure Kubernetes out all on your own. Rancher is open source software, with an enormous community of users. Managing Kubernetes installed in your local or remote development environment is so much easier with Rancher. Now with full support for Windows containers, Istio service mesh, and enhanced security for cloud-native workloads, Rancher helps developers innovate faster and with greater confidence.

RancherOS is the smallest, easiest way to run Docker in production. Every process in RancherOS is a container managed by Docker. This includes system services such as udev and syslog. Because it only includes the services necessary to run Docker, RancherOS is significantly smaller than most traditional operating systems. By removing unnecessary libraries and services, requirements for security patches and other maintenance are also reduced. This is possible because, with Docker, users typically package all necessary libraries into their containers. Another way in which RancherOS is designed specifically for running Docker is that it always runs the latest version of Docker. This allows users to take advantage of the latest Docker capabilities and bug fixes. Like other minimalist Linux distributions, RancherOS boots incredibly quickly. Starting Docker containers is nearly instant, similar to starting any other process.

Gogs is a simple, stable, self-hosted Git service that is easy to install and setup. All you have to do is run the binary on any platform that Go supports: Linux, macOS and Windows. You may also install from source, from packages, or ship with Docker or Vagrant. Gogs is very lightweight with minimal hardware requirements, running on Raspberry Pi and even on NAS devices. Gogs offers plenty of great features, including various access repositories, repository and organization webhooks, repository Git hooks, repository management and so much more. It also offers software, service and product support for various areas such as project management (Kanboard, Taiga), DevOps (Fabric8) and team communication (BearyChat).

Devtron deeply integrates with products across the lifecycle of microservices,i.e., CI, CD, security, cost, debugging, and observability via an intuitive web interface. Devtron is designed to be modular, and its functionality can be easily extended with the help of integrations. Devtron CI/CD with GitOps integration is used to automate the builds and deployments and enables the software development teams to focus on meeting the business requirements, code quality, and security. Devtron leverages Kubernetes auto-scaling and centralized caching to give you unlimited cost-efficient CI workers. Supports pre-CI and post-CI integrations for code quality monitoring. Provides deployment metrics like; deployment frequency, lead time, change failure rate, and mean-time recovery. Seamlessly integrates with Grafana for continuous application metrics like CPU and memory usage, status code, throughput, and latency on the dashboard.

Otomi is an open source self-hosted PaaS to run on top of any Kubernetes cluster and is placed in the CNCF landscape under the PaaS/Container Service section. A PaaS attempts to connect many of the technologies found in the CNCF landscape in a way to provide direct value. Deploy containerized apps with a few click without writing any K8s YAML manifests. Get access to logs and metrics of deployed apps. Store charts and images in a private registry. Build and run custom CI pipelines. Enable declarative end-to-end app lifecycle management. Configure ingress for apps with a single click. Manage your own secrets. Onboard development teams on shared clusters in a comprehensive multi-tenant setup. Get all the required observability tools in an integrated way. Ensure governance with security policies. Implement zero-trust networking with east-west and north-south network control within K8s. Provide self-service features to development teams.

Last.Backend is a company that provides DevOps products for IT companies across the world. Last.Backend container management platform is the new and modern open-source container management system with service discovery, overlay networks, and more. The container platform is an open-source system for automating the deployment, scaling, and management of containerized applications. It contains a set of technologies like container scheduling, service discovery, overlay network, container runtime, container images runtime, load-balancing and more. All of these technologies are provided out of the box and don't require additional research and setup. Our design principles allow us to create an extendable and powerful system. We separated runtime into the particular package and used interfaces to add the ability to extend supported technologies.
