What this post added

This post details the technical steps and considerations for migrating from Bamboo CI/CD to GitLab CI/CD. It outlines the differences in organizational structure (Projects/Plans vs. single platform with .gitlab-ci.yml), the concepts of Agents (Bamboo) vs. Runners (GitLab), and the configuration methods (Bamboo Specs vs. .gitlab-ci.yml). Specific conversion guidance is provided for container images, stages, variables, build jobs (tasks vs. script commands), and deployment jobs. It also highlights GitLab's additional features like application security, compliance policies, CI/CD catalog, and package/container registries.
