Add self-hosted runner environment verification workflow

[Copilot]

Adds a minimal workflow to verify self-hosted Linux runner environment and Docker availability before expanding CI/CD infrastructure.

Changes

• .github/workflows/verify-runner.yml: New workflow triggered on manual dispatch and push to develop
  • Prints runner metadata (name, OS, disk space, user)
  • Validates Docker installation and configuration
  • Tests Docker build/run with Alpine 3.18 minimal image

Usage

Manual trigger via Actions UI or automatic execution on develop branch pushes. Workflow validates:

• Runner accessible and properly configured
• Docker daemon functional
• Image build/run capabilities operational

Original prompt

Add a minimal GitHub Actions workflow .github/workflows/verify-runner.yml that runs on the on-prem linux self-hosted runner and verifies environment setup for subsequent CI/CD work.

Requirements:

• Workflow name: Minimal Runner Environment Check
• Trigger: workflow_dispatch and push to develop
• jobs:
  • check-runner:
    runs-on: [self-hosted, linux]
    steps:
    - name: Print runner info
    run: |
    echo "Runner: ${{ runner.name }}"
    uname -a
    lsb_release -a || cat /etc/os-release
    df -hT
    whoami
    - name: Check Docker install
    run: |
    docker --version
    docker info
    - name: Test Docker build
    run: |
    echo -e "FROM alpine:3.18\nCMD ['echo', 'hello from alpine!']" > Dockerfile
    docker build -t test-alpine .
    docker run --rm test-alpine echo "hello from inside Docker"
    docker rmi test-alpine

Acceptance:

• Action prints runner metadata
• Docker is found and functional
• Docker build and run of a minimal image succeed
