What is the connection between DevOps and Docker?

28 Haz 04:20

DevOps and Docker are actually connected by the fact that both serve the same goal: making application development, deployment, and infrastructure management faster, more reliable, and automated. Docker's most fundamental role in DevOps is ensuring applications are packaged in "containers." This eliminates inconsistencies between development, testing, and production environments because the environment in which the application will run is already defined within the Docker container. For example, at one of my clients, we manage microservices running on different servers using Docker Swarm, and we’ve never encountered any compatibility issues when automatically deploying new versions through our CI/CD pipeline. In the CI/CD process, Docker is almost indispensable. For instance, when integrated with GitLab CI/CD, it automatically builds a Docker image after each commit and pushes it to the registry, then deploys it to production servers. This way, we standardize the process and minimize manual errors. Recently, in a project where I used Docker, most of the "it doesn’t work" issues I faced before disappeared thanks to this approach.
