Faster and simple maintenance page

Sun, 04 Feb 2024 00:00:00 +0000

Working on different platform either to update, patch, etc need to be notificate for those people that consume that services, it shouldn’t change if that service it’s internal, you must notificate your teams about it.

When you’re into your maintenance window you can use a faster way to broadcast everyone you’re working on it; I use this simple solution when I was working into a Jenkins migration, hence I stop the jenkins service and instead of 500 html error I developed a simple html text exposing it by a nginx container by the root path.

Trigger pipelines by using the API

Sat, 15 Jul 2023 00:00:00 +0000

When you join a new project, company, customer, etc. (you’re still in the onboarding phase 😅), meanwhile you may find that you need to make a few changes to get your team’s production pipelines up and running. In this case, you can call an API trigger from one project to another (this is just a example).

I’ve been in the situation described above before, and it was how I discovered this amazing feature in GitLab.

Cloining a repo and setting up as artifact

Tue, 20 Dec 2022 00:00:00 +0000

On this post I will give you an example of how to clone a repo into your pipeline and use it for other jobs.

As you can read from Gitlab official documentation artifact can output an archive of files/directories. I set the following example:


  artifacts:
    paths:
      - <project_name>
    exclude:
      - <project_name>/.git/**/*
    expire_in: 60 seconds

We need to call the artifacts by using “artifacts” keyboard in the pipeline, in this example paths keyboard which files/directories add into artifacts.

Trigger pipelines in Gitlab

Thu, 10 Nov 2022 00:00:00 +0000

The following post is example of how to activate and use Trigger pipeline by API the official documentation over here as it mentioned is can be use “to trigger a pipeline for a specific branch or tag”; for our example I use it to activate a pipeline into specific branch.

Steps:

repoA will be the main one where the pipeline trigger it will be activate

From repoA go to Settings-CI/CD-Pipeline triggers
Click on “add trigger” copy your token
From repoB that will be our caller of the repoA pipeline create a variable where you can paste the token.
Finally into your pipeline on repoB you can add something like below:

The best part is that you can reference to specific branch ref="<branch_name>".

Ansible missing sudo

Sun, 03 Apr 2022 00:00:00 +0000

Ansible FAILED! => {"msg": "Missing sudo password"}

I have a couple of ansible-playbook, from one of my endpoint device started to prompt missing sudo password due there is needed a sudoers access, thus this is one of the solutions.

login by ssh to the device, where ansible can’t login.
go to /etc/sudoers.d/
create a new entry eg: “023_user-nopass”
add the following line “user ALL=(ALL) NOPASSWD: ALL” into the file “023_user-nopass”
change the permission by using:

sudo chmod 440 023_user-nopass

NOTE: please change value for your normal user access -not the root one-
