As we progress through #90DaysOfDevOps, the challenges become more intricate, and today's task delves into the seamless integration of Docker with Jenkins Declarative Pipelines. In our journey so far, we've explored the fundamentals of Jenkins pipelines, and now, it's time to elevate our CI/CD workflows with the power of Docker.
Why Docker in Jenkins Pipelines?
Docker brings a transformative impact to DevOps practices by providing a standardized and reproducible environment. Integrating Docker with Jenkins pipelines offers several advantages:
Consistency Across Environments: Docker containers encapsulate dependencies, ensuring that the build, test, and deployment environments remain consistent.
Isolation and Portability: Containers isolate applications and their dependencies, facilitating portability across different stages of the development lifecycle.
Efficient Resource Utilization: Docker's lightweight nature enables efficient utilization of resources, making CI/CD processes faster and more resource-friendly.
Task 1: Docker Build with sh in Jenkins Declarative Pipeline
In this task, we leverage the sh command within the Jenkins Declarative Pipeline to execute Docker build commands. Here's a snippet illustrating the process:
Here, the docker build command constructs an image with the specified tag, utilizing the Dockerfile and application files within the build context.
Task 2: Docker-Integrated Jenkins Declarative Pipeline using Docker Groovy Syntax
To further refine the integration, we transition to employing Docker Groovy syntax within the Jenkins Declarative Pipeline:
In this revised approach, the docker.build command incorporates logic to handle existing containers more gracefully.
