How to make correct my azure deployment issue by rearranging my azure-pipelines.yml? - azure-devops

Question

I am trying to establish a pipeline by using azure cloud and devops. But I got an error below while deploying from succeeded building. How can I solve this issue?
I read an article it is awesome "http://www.alessandromoura.com.br/2020/04/23/azure-devops-publish-and-download-artifacts/"
I applied your rule sets but I got error always below :
Error: No package found with specified pattern: D:\a\r1\a***.zip
Check if the package mentioned in the task is published as an artifact in the build or a previous stage and downloaded in the current job.
azure-pipelines.yml :
# Docker
# Build and push an image to Azure Container Registry
# https://learn.microsoft.com/azure/devops/pipelines/languages/docker
trigger:
- main
resources:
- repo: self

Answer 1

Your pipeline creates and pushes image to container registry so you don't have there pipeline artifacts. This is why DownloadPipelineArtifact throws error.
DownloadPipelineArtifact makes sens only if you use PublishPipelineArtifact before. This doc - Publish and download artifacts in Azure Pipelines describe it very well.
There is also a way to download artifacts from another pipeline - but it requires to use resource, but you don't have defined pipeline resource in your pipeline.
So all works as expected. Can you explain what actually do you want to download and what achieve by that?
