Add copilot-setup-steps.yml for GitHub Copilot coding agent environment

[Copilot]

Configures the GitHub Copilot coding agent's ephemeral environment with required dependencies for this Docusaurus project.

Changes

• .github/workflows/copilot-setup-steps.yml: Workflow that provisions Node.js 20, installs Yarn dependencies, and sets up a Dragonfly instance
  • Job name copilot-setup-steps (required by Copilot)
  • Caches Yarn dependencies for faster subsequent runs
  • Pulls and runs docker.dragonflydb.io/dragonflydb/dragonfly container in daemon mode on port 6379
  • Triggers on manual dispatch and workflow file changes for testing

Context

Per AGENTS.md, this project requires Node.js >= 16.14 and Yarn. The workflow ensures these are available before Copilot starts coding, along with a running Dragonfly instance for testing and development purposes, eliminating setup failures and improving agent reliability.

Also pull and run docker.dragonflydb.io/dragonflydb/dragonfly container in daemon mode as part of the setup flow @copilot

[Copilot]

Also pull and run docker.dragonflydb.io/dragonflydb/dragonfly container in daemon mode as part of the setup flow @copilot

Added Dragonfly Docker container setup to the workflow in commit 156e440. The workflow now pulls docker.dragonflydb.io/dragonflydb/dragonfly and runs it in daemon mode on port 6379.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• docker.dragonflydb.io
  • Triggering command: /usr/bin/docker docker pull docker.dragonflydb.io/dragonflydb/dragonfly (dns block)
• version.dragonflydb.io
  • Triggering command: /usr/local/bin/dragonfly dragonfly --logtostderr (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
