[Question]: How to use Custom PHP/Alpine image as running container ?

[abenevaut]

Describe your question

I build a custom docker image to run CI for a PHP Application. I'm looking the right way to use it inside azure pipelines.
Now, the image is correctly pulled and started ("resources" container too) but pipeline fails when trying to execute the first "script" task (named 'composer install' in following example).

Following, a pipeline example close as possible of mine:

trigger:
  branches:
    include:
      - dev

resources:
  containers:
    - container: azsql
      image: mcr.microsoft.com/azure-sql-edge
      name: sql-server
      hostname: sql-server
      ports:
        - 1433:1433
      env:
        ACCEPT_EULA: 1
        SA_PASSWORD: yourStrong(!)Password
        MSSQL_PID: Developer

stages:

  - stage: Test
    displayName: TestStage
    jobs:
      - job: TestPHPService
        pool:
          vmImage: 'ubuntu-latest'
        container:
          image: my.azurecr.io/my/alpine-img:latest
          endpoint: 'my-service-connection'
        services:
          azsql: azsql
        steps:

          - script: |
              composer -V
              composer validate --strict
              composer install --optimize-autoloader --no-interaction --prefer-dist
            displayName: 'composer install'
            workingDirectory: $(System.DefaultWorkingDirectory)

The output looks like:

Starting: composer install

My image contains bash, nodejs & npm. I do not know with tool i missed.

I found this documentation https://learn.microsoft.com/en-us/azure/devops/pipelines/process/container-phases?view=azure-devops&tabs=windows#nonglibc-based-containers

Applied the label and added forgotten binaries in custom image, but still failing.

LABEL "com.azure.dev.pipelines.agent.handler.node.path"="/usr/bin/node"

RUN apk add --no-cache --virtual .pipeline-deps readline linux-pam \
      && apk add bash sudo shadow nodejs npm \
      && apk del .pipeline-deps \
      && rm -rf /var/cache/apk/*

##[error]Exit code 126 returned from process: file name '/usr/bin/docker', arguments 'exec -i -u 1001  -w /home/vsts_azpcontainer c81f6c549eb45156d0aa0cb22df7266f88dca562ab488fddabd4d80c4e1fcea1 /usr/local/bin/node /__w/_temp/containerHandlerInvoker.js'.

In documentation a sentence say "If you depend on any in-box or Marketplace tasks, also supply the binaries they require.", i have no docker task or script in my pipeline, this is probably related too the agent and custom image
