Gitlabrunner Playground

Welcome to the GitLab Runner Playground!

GitLab Runner — the open-source agent that executes CI/CD jobs defined in your .gitlab-ci.yml. Learn registration, executor types, and pipeline execution.

What’s Pre-installed

• gitlab-runner (latest) — the full runner binary
• Shell: bash (running as codeground)
• Base tools: curl, wget, git, vim, nano

Quick Start

gitlab-runner --version
gitlab-runner --help
gitlab-runner status

Common Workflows

# Register a runner (shell executor)
gitlab-runner register \
  --non-interactive \
  --url "https://gitlab.com/" \
  --registration-token "YOUR_TOKEN" \
  --executor "shell" \
  --description "my-runner" \
  --tag-list "linux,shell"

# List registered runners
gitlab-runner list

# Run a single job manually
gitlab-runner exec shell <job-name>

Advanced Tips

# Verify runner configuration
cat ~/.gitlab-runner/config.toml

# Run in debug mode
gitlab-runner --debug run

# Custom executor: Docker (requires Docker daemon)
# Register with executor=docker and image=alpine:latest

# .gitlab-ci.yml example
cat > .gitlab-ci.yml <<'EOF'
stages:
  - build
  - test

build:
  stage: build
  script:
    - echo "Building..."

test:
  stage: test
  script:
    - echo "Testing..."
EOF
