I want to fetch the description of the merge request to generate changelog. Is it possible to get the description??
In GitLab CI/CD's predefined environment variables there are some variables related to merge requests, such as:
CI_MERGE_REQUEST_ASSIGNEES
CI_MERGE_REQUEST_CHANGED_PAGE_PATHS
CI_MERGE_REQUEST_CHANGED_PAGE_URLS
CI_MERGE_REQUEST_ID
CI_MERGE_REQUEST_IID
CI_MERGE_REQUEST_LABELS
CI_MERGE_REQUEST_PROJECT_PATH
CI_MERGE_REQUEST_PROJECT_URL
CI_MERGE_REQUEST_REF_PATH
CI_MERGE_REQUEST_SOURCE_BRANCH_NAME
CI_MERGE_REQUEST_SOURCE_BRANCH_SHA
CI_MERGE_REQUEST_SOURCE_PROJECT_ID
CI_MERGE_REQUEST_SOURCE_PROJECT_PATH
CI_MERGE_REQUEST_SOURCE_PROJECT_URL
CI_MERGE_REQUEST_TARGET_BRANCH_NAME
CI_MERGE_REQUEST_TARGET_BRANCH_SHA
CI_MERGE_REQUEST_TITLE
CI_MERGE_REQUEST_EVENT_TYPE
⋮
You can easily access them inside pipelines and jobs.
EDIT:
It seems there is no variable to access the merge requests description. I think using GitLab's Merge requests API can be helpful. So by requesting below URL inside your pipeline (using curl or other tools) you will get access to more information about a single merge request:
GET $CI_API_V4_URL/projects/$CI_PROJECT_ID/merge_requests/$CI_MERGE_REQUEST_IID
