Container 'docker' exceeded memory limit error - On log doesn't use all the memory.

[MadCatPT]

I'm just building a small, single page Blazor Web Assembly page and deploying it to Azure. Sometimes I would get Pipeline failures, but on rerun they would work.

Today I'm getting a "Container 'docker' exceeded memory limit." error, I followed the troubleshooting steps and added the lines to show the memory usage that doesn't get anything near the maximum.

This happens after "Publishing to directory ...".

Update:

I was using Microsoft's yaml for the build and deploy, for it to suddenly stop working was really weird, I was just using a very small part of the memory, even tried the 2x, but still had issues.

I went back and saw that the occasional fails I got were the same issues, so something has probably changed int the backend for it to now always happen and not some rare times. So I started trying to allocate memory directly to docker and lo and behold the issue was fixed.

Here is my final yaml, the bold part was added to fix the issue.

definitions:
  services:
    docker:
      memory: 1024
pipelines:
  branches:
    main:
      - step:
          name: Deploy to test
          deployment: test
          script:
            - chown -R 165536:165536 $BITBUCKET_CLONE_DIR
            - pipe: microsoft/azure-static-web-apps-deploy:main
              variables:
                APP_LOCATION: $BITBUCKET_CLONE_DIR/TeachingTool
                OUTPUT_LOCATION: wwwroot
                API_TOKEN: $deployment_token

Hope it may help someone in the future.

I added the solution I found to the question.

Added this to the top of the yaml.

definitions:
  services:
    docker:
      memory: 1024
