Managing containerized applications, ensuring their deployment, scaling, and orchestration withinKubernetes clusters.• Collaborating with development and operations teams to troubleshoot issues, optimize resource usage, and enhance security within Kubernetes ecosystems.• Create and maintain Helm charts that package applications, services, and their dependencies into a reusable format.• Publish Helm charts to a Helm chart repository for easy distribution and sharing within the organization.• Implemented and managed GitOps workflows, maintaining declarative infrastructure as code. Installed and configured ArgoCD for managing Kubernetes applications, ensuring secure access and authentication.• Created and managed applications within ArgoCD, ensuring synchronization with Git repositories. Integrated ArgoCD into CI/CD pipelines, automating application deploymentswith the help of ShellScripting.• Proficiently Operated Docker for containerization, encloses the complete Docker lifecycle, from creating Dockerfiles, building custom images, and pushing them to image registry to DockerHub.• Mounted a docker volume to securely share data between host machine and containers. Created custom docker network to isolate services and controlling communication this way reduced latency and improve performance.• Implemented security best practices for Docker containers, including image scanning, access control, and vulnerability management to protect against potential threats.• Design, configure, and maintain continuous integration and continuous deployment (CI/CD) declarative pipelines using Jenkins, integrating with version control systems (GitHub) to automate builds, testing, and deployment processes.• Install, configure, and manage Jenkins plugins to extend functionality and integrate with various tools and services, such as Docker, Kubernetes and cloud providers.• Implemented the successful integration of SonarQube, resulting in an improvement in code quality and a significant reduction in security vulnerabilities, ensuring a robust and reliable software product.• Design, develop, and maintain Ansible playbooks and roles to automate infrastructure provisioningand configuration across multiple environments.• Collaborate with development and product teams to design and choose the most suitable deployment strategy (Blue/Green, Canary, Recreate) based on project requirements andconstraints.
