What is CI/CD, and what is CI/CD ops for k8s?
Here panelists discuss their experience of dealing with the different scales, and also they talk about how the experience of dealing with the multi-cloud Kubernetes Environment.
CI/CD stands for Continuous Integration/Continuous Deployment. It is a set of software engineering practices that aim to automate and streamline the process of building, testing, and deploying software changes to production. The primary goal of CI/CD is to help teams deliver software faster, more reliably, and with higher quality. CI/CD involves several steps, including code compilation, automated testing, and packaging.
Continuous Integration (CI) is integrating code changes into a shared repository frequently, usually several times a day. It ensures that each change to the codebase is tested and validated. Continuous Deployment (CD) is the practice of automatically deploying code changes to production after they pass a series of automated tests. CI/CD Ops for k8s, or CI/CD for Kubernetes, is a set of practices and tools used to implement CI/CD in a Kubernetes environment. Kubernetes is an open-source container orchestration platform that helps automate containerized applications' deployment, scaling, and management.
CI/CD Ops for k8s involves using tools such as Jenkins, GitLab, or Spinnaker to automate the entire CI/CD pipeline, including building and testing Docker images, deploying them to Kubernetes clusters, and monitoring the entire process. It helps teams ensure that their applications always run the latest code and that any changes are deployed quickly and efficiently.
The evolution of CI/CD
This is the segment where panelists talk about how they dealt with Complex CI/CD setups while working with the services like ECS and/or Virtual Machines. Where the CI/CD setup was done using complex tools like Jenkins and other applications that are not suitable for delivering a solution to the application on a bigger scale.
Continuous Integration (CI) first emerged in the early 2000s as a way to improve software development processes. At that time, the practice involved frequently integrating code changes into a shared repository and automating the process of building and testing the code. The goal was to catch integration issues early and ensure the codebase remained stable.
As the software development process became more complex and distributed, the concept of Continuous Deployment (CD) emerged. Continuous Deployment involves automatically deploying code changes to production after they pass a series of automated tests. Over time, the concept of CI/CD has evolved to include more automation, testing, and deployment scenarios. With the advent of cloud computing and containerization technologies like Docker, CI/CD has become even more critical.
Today, CI/CD involves a fully automated pipeline that includes continuous testing, security scanning, and deployment to multiple environments, including production. It also includes monitoring and logging to ensure that any issues are quickly identified and resolved.
