Create GitLab merge request from cli

Fri, 03 Sep 2021 00:00:00 +0000

Do not push your branch before the following commands. If you push your branch before it will not work. Git response is going to be Everything up-to-date and the merge request will not be created.

Push my-branch to the remote repository and create a new merge request from our branch to the main branch of the project.

git push -o merge_request.create origin my-branch

Push my-branch to the remote repository and the target branch work with the merge request title <title> and a merge request description <description>, setting the merge request to remove the source branch when it’s merged:

git push \
 -o merge_request.create \
 -o merge_request.target=work \
 -o merge_request.title="<title>" \
 -o merge_request.description="<description>" \
 origin my-branch

OR statement within jq select

Thu, 26 Aug 2021 00:00:00 +0000

Initial json input

{
 "nodes": [
 {
 "name": "crc-4727w-master-0",
 "cpu": 75,
 "memory": 82
 },
 {
 "name": "crc-4727w-worker-0",
 "cpu": 65,
 "memory": 70
 },
 {
 "name": "crc-4727w-worker-1",
 "cpu": 60,
 "memory": 68
 }
 ]
}

The jq select filter with a comparison
- Is going to show the nodes that the cpu usage is greater than 70% OR the memory usage is greater than 90%

jq '.nodes[] | select(.cpu >=70 or .memory >=90)'

Result

{
 "name": "crc-4727w-master-0",
 "cpu": 75,
 "memory": 82
}
