feat: migrate from GitPod to GitHub Codespaces #479
Conversation
Add comprehensive GitHub Codespaces configuration to replace GitPod as the primary cloud development environment (GitPod free tier has sunset). Changes: - Add .devcontainer/devcontainer.json with Docker-in-Docker and GitHub CLI - Add .devcontainer/setup.sh for automated environment setup - Add dockerfiles/codespacesURL.sh for Codespaces URL configuration - Add CODESPACES_MIGRATION_PLAN.md with detailed migration strategy - Update README.md with Codespaces quick start and instructions - Update .gitignore for local development files - Set default empty values for GITPOD_WORKSPACE_URL to suppress warnings Features: - Automatic yq installation for YAML processing - Port forwarding for Jenkins (8080) with public visibility - Environment-aware URL configuration using CODESPACE_NAME - Maintains backward compatibility with GitPod configuration - 60 hours/month free tier (sufficient for all tutorials) - Welcome message displayed on every terminal session The migration maintains dual support for both Codespaces and GitPod during the transition period, allowing users to choose their preferred environment.
Configure setup script to append welcome message to .bashrc so it displays automatically on every new terminal session in Codespaces. This is more reliable than postStartCommand which doesn't always show output in the terminal.
Add gh CLI command to automatically set port 8080 to public during setup. Create .devcontainer/README.md with manual steps for port visibility. The devcontainer.json visibility setting doesn't reliably work, so we now: 1. Attempt automatic setting via gh CLI in setup.sh 2. Provide clear manual steps in README if automation fails This addresses the persistent issue where ports default to private even with visibility: public in devcontainer.json.
Change onAutoForward from 'openPreview' to 'openBrowser' to avoid preview pane issues with Jenkins security headers. The VS Code preview shows 'Please reopen the preview' due to Jenkins X-Frame-Options headers. Opening in a regular browser tab works fine. Updated README to clarify this behavior.
Add note that GitPod is legacy (free tier sunset) and we've migrated to GitHub Codespaces. Disable Dependabot monitoring of GitPod image updates by setting open-pull-requests-limit to 0. Codespaces uses devcontainer.json which cannot be monitored by Dependabot (not a Dockerfile). Manual updates as needed.

Code Review
This pull request successfully migrates the project's cloud development environment from GitPod to GitHub Codespaces, which is a significant improvement. The new Codespaces configuration is well-documented and includes a robust setup script. The changes to maintain backward compatibility with GitPod are also well-implemented. My review includes a few suggestions to enhance the maintainability and robustness of the new configuration, primarily by pinning dependency versions and using environment variables instead of hardcoded paths. Overall, this is a high-quality contribution.

For better reproducibility and to avoid unexpected breaking changes from automatic updates, it's a best practice to pin the versions of dev container features instead of using latest. You can find the latest stable versions on the respective feature's GitHub page.

To ensure reproducible builds and prevent unexpected issues from automatic updates, it's recommended to pin the version of yq being installed rather than fetching latest.

Instead of hardcoding the workspace path, it's more robust to use the $GITHUB_WORKSPACE environment variable, which is provided by GitHub Codespaces. This makes the script more portable. Using single quotes for the echo commands will ensure the variable is written to .bashrc literally and expanded upon sourcing the file.

To make this script more robust and portable, consider using the $GITHUB_WORKSPACE environment variable instead of a hardcoded path. This variable is available in Codespaces and points to the root of the workspace.

You can simplify this file update by using yq's in-place editing feature (-i or --inplace), similar to how you use it on line 63. This avoids creating and moving a temporary file.

In docker-compose.yaml around line 200, the GITPOD_WORKSPACE_URL environment
variable is currently set without a safe default which can lead to an empty
value being propagated; update this to use a fallback like
${GITPOD_WORKSPACE_URL:-https://gitpod.io} or another appropriate default (or
change to fail-fast by validating and exiting) so downstream scripts get a valid
URL; additionally, update build-docker-compose.yaml occurrences at lines 122,
144, 167, and 190 to mirror the same default syntax or consolidate the variable
via an env_file or an anchored YAML value so all references are consistently
guarded; also add a defensive check in dockerfiles/gitpodURL.sh (line 7) to exit
with a clear error if GITPOD_WORKSPACE_URL is empty or to use the same fallback
before extracting service_url.
- Pin yq version to v4.44.3 with curl fallback - Pin devcontainer features (Docker 27.0, gh CLI 2.62) - Add shell safety flags (set -Eeuo pipefail) - Replace hardcoded paths with git rev-parse - Improve variable quoting throughout scripts - Add validation checks (yq exists, gh authenticated) - Enhance error handling in all scripts Addresses all valid suggestions from AI reviewers (CodeRabbitAI and Gemini).
- Add updatecli manifest for yq, Docker, and GitHub CLI versions - Update dependabot.yml to reference UpdateCLI for Codespaces deps - Clarify port visibility is not blocking access in README - Document that private ports work for Codespace owners UpdateCLI will now automatically create PRs when new versions of devcontainer dependencies are available.

- Confirm that the tutorial image actually uses admin/admin as its default login.
The dockerhub-image-exists condition was missing the required sourceid attribute, causing UpdateCLI validation to fail. Tested locally with updatecli diff - manifest now works correctly and detects available updates: - yq: v4.44.3 → v4.48.1 - Docker: 27.0 → 28.5 - GitHub CLI: 2.62 → 2.81.0 The manifest will run successfully once this PR is merged to main.

77-96: Prefer structured updates over regex for devcontainer.json.Regex works but is brittle. Consider UpdateCLI’s JSON target to set:
- features["ghcr.io/devcontainers/features/docker-in-docker:2"].version
- features["ghcr.io/devcontainers/features/github-cli:1"].version
This avoids regex drift if formatting changes.

66-76: yq version replacement verified: the regex matches the singleYQ_VERSIONdefault in.devcontainer/setup.shand preserves the leadingv.
29-43: Confirm devcontainer feature accepts major.minor version
Thedocker-versiontransformer normalizes tags tomajor.minor(e.g. “27.3” from “27.3.1”) and injects that into the Docker-in-Docker feature’sversionfield—please verify the feature accepts amajor.minorvalue as valid input.
Fixed three pattern matching issues: 1. yq pattern: Added missing closing brace '}' before final quote 2. Docker pattern: Simplified to match line-by-line with search filter 3. GitHub CLI pattern: Simplified to match line-by-line with search filter Tested locally - all targets now detect updates correctly: - ⚠ [yq-setup-script] v4.44.3 → v4.48.1 - ⚠ [docker-feature-version] 27.0 → 28.5 - ⚠ [github-cli-feature-version] 2.62 → 2.81.0
Replaced echo with printf for lines containing ANSI color codes to improve portability across different shells. Fixes Codacy warnings: - Line 44: echo → printf for color formatting - Line 45: echo → printf with proper format string - Line 51: echo → printf in loop with format placeholders The echo command's handling of escape sequences is not standardized across shells. printf is the portable solution and is recommended by POSIX for formatted output.

Replace string concatenation with direct printf calls for building the profiles list message. This is more maintainable and consistent with other printf statements in the script. Benefits: - Avoids error-prone string building with ANSI escape sequences - More consistent with the rest of the script - Cleaner and easier to maintain - No temporary variables needed Addresses Copilot AI code review suggestion.
