Github workflow

Workflow:
​The image shows a continuous, cyclical process, highlighting the core principles of DevOps: automation, collaboration, and continuous feedback.
#​Plan: This initial phase involves defining requirements, setting goals, and planning the software development. It's about understanding what needs to be built.
#​Code: Developers write the code for the . Version control systems like Git are crucial here for managing changes and collaboration.
#​Build: The code is compiled, packaged, and prepared for deployment. Tools like Jenkins (often used for Continuous Integration) automate this process, ensuring that new code integrates seamlessly with existing code.
​Test: The built application undergoes various tests (unit, integration, system, performance) to ensure quality and functionality. This phase is often automated.
#​Deploy: The tested application is released and deployed to the production environment. This step is also heavily automated, using tools to ensure consistent and reliable deployments.
​Operate: Once deployed, the application is actively running and being monitored in the production environment.
#​Monitor/Operate: This phase involves observing the application's performance, stability, and user experience. Feedback from monitoring tools (Prometheus is a common example) is fed back into the planning phase.
​Continuous Feedback & Optimization:
​The arrows indicating "Continuous Feedback & Optimization" emphasize that DevOps is not a linear process. Insights gained from operating and monitoring are used to refine planning, coding, and subsequent iterations, leading to continuous improvement.
​Key Tools Mentioned in the Image:
​Git: A distributed version control system for tracking changes in source code.
​Jenkins: An open-source automation server for Continuous Integration (CI) and Continuous Delivery (CD).
​Docker (Docler in the image seems to be a typo/variant): A platform for developing, shipping, and running applications in containers.
​Prometheus: An open-source monitoring system with a flexible query language.
