Azure DevOps Pipelines : ##[error]Unhandled: No Dockerfile matching /home/vsts/work/1/s/Dockerfile_glpi_v1 was found

Question

Hello, I'm in internship trying to learn how to become a cloud administrator (DevOps). To do that I practice and try to deploy resources with different tools to learn the basics, the best practises and so much more.

I decided to try Azure DevOps Pipelines in order to deploy GLPI with its database on a AKS cluster. I successfully created my project (my code is stored on GitHub) and the necessary services connections Kubernetes (with KubeConfig) and Docker for my pipeline.

I had no issue deploying my aks cluster with .yaml files with kubectl commands on the azure Cloud Shell.

Now I want to use Pipelines to build and push my GLPI image to a Docker repository I created. I variabilize and as I have a .env file for GLPI I use the commands build and push separately.

Now when I run my pipeline I get the following error : ##[error]Unhandled: No Dockerfile matching /home/vsts/work/1/s/Dockerfile_glpi_v1 was found.

I checked so many posts about this error to understand and finally tried to use buildContext: (Build.SourcesDirectory) however the issue persists. I checked my directory with pwd and got as a result : /home/vsts/work/1/s.

My pipeline code is the following :

trigger:
  batch: true
  branches:
    include:
    - main
  paths:
    include:
    - azure-pipelines.yml

            echo
            echo Have a good day !

The path of my Dockerfile_glpi_v1 (I use VS Code to push it to GitHub) is : Projet > Projet_fil_rouge_GLPI There are several dockerfiles and .env file because I wish to deploy several versions of GLPI but I start with only one first.

Could you please enlighten me ? I apologize if this is because of my inexperience or a mistake on my part.

Thank you very much.
