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
}

Gitkraken Ambassador

Table of Contents

Hello again,

I’m happy to announce that I’m participating in the GitKraken Ambassador program.

For me, it is a joy that the GitKraken team trusts me for this work.

GitKraken Ambassador

I have been a GitKraken advocate even before they launched this program. I always recommend it to all my friends and colleges because I have loved it since the first time I used it, back in 2018.

Now, I’m being named Ambassador to actively promote it in community events, meetings with other Ambassadors, beta-testing of new functionality, etc. Also, I will create some post showing/explaining how I use GitKraken in my job, that is A LOT.

For joining the GitKraken Ambassador team, I received:

Free GitKraken Pro Account ($79 value)
Ambassador Starter Kit: Stickers, Swag & Resources
Access to a private Ambassador Slack Channel
Exclusive Ambassador Content & early access to beta features
Access to GitKraken Product Team to share feedback and get exclusive insight

GitKraken Ambassador Starter Kit

What is GitKraken?

Let’s start defining what is GitKraken for me and how I use it.

GitKraken provides me the easiest, safest, and most powerful way to interact/work with:

Git
GitHub
GitLab,
and more Source Code Management (VCS)

becoming the best complement to manage your source code.

As an Infrastructure consultant, I contribute to Ansible playbooks/roles, Terraform provisioning, Kubernetes/OpenShift manifests, Documentation, and more, but my profile is not necessary as a Developer. I consider myself more a DevOps Practitioner where, from my perspective, I write code for Infrastructure in a declarative way; that being said, my workflow is slightly different from a Developer.

That means I usually do all my code in VSCode. Sometimes I commit using the terminal and sometimes using the Kraken. Once I’m ready to push my changes, I switch to GitKraken to review that I’m in the correct branch/tree/tag, if there are no conflicts, etc. and, then I do push/merge it in a collaborative way and keeping the order that the project requires and that I want to show. That personal workflow always helped me to avoid mistakes in my job.

What I like

GitKraken has a pretty neat interface where it is easy to find all I need for that git workflow.

GitKraken Interface
Multiple git profiles support

GitKraken Profiles 1/2

GitKraken Profiles 2/2
Easy drag and drop Pull-Request/Merge-Request integration

GitKraken Drag & Drop Pull Request

What I don’t like

Sometimes, when my computer has high resources usage, like when I’m running some containers/virtual machines, GitKraken produces a slow down for a bit like some other GUI’s.

Wrapping Up

So, starting today, I’m going to generate content related to Git/Gitkraken, and to achieve this, I will write about how I integrate GitKraken into my daily work.

If you want to start using GitKraken, you can download the Kraken and try it by yourself! Furthermore, I recommend to use my referral code when you sign in.

Happy coding!
