Hướng nghiên cứu

Bắt đầu với lệnh gọi được đề xuất read-configuration --include-merged-configuration và hai script devcontainers CLI được tham chiếu. Theo dõi cách Envbuilder đọc devcontainer.json của dự án và xử lý các features, sau đó so sánh kết quả với đầu ra ví dụ. Hoàn tất khi lệnh xuất ra một cấu hình đã hợp nhất, chứa các thiết lập của dự án và các đóng góp của features.

Mô tả

Note: If we implement option 1 from https://github.com/coder/envbuilder/issues/211, we could punt this feature for the time being.

This feature is a pre-requisite for generating a computed devcontainer.json for use by e.g. coder modules. This can help resolve issues like https://github.com/coder/envbuilder/issues/68 where a list of extensions needs to be available during installation of vscode, code-server, etc.

This commands main purpose is to output a merged configuration based on the projects devcontainer.json as well as configuration introduced by features.

A logical approach would be to mimic @devcontainer/cli output. Doing so would make envbuilder a versatile tool for interpreting devcontainer features, and potentially a drop-in single binary alternative.

Here's an example output from @devcontainer/cli when run against the microsoft/vscode repo.

devcontainer read-configuration --include-merged-configuration --log-format json --workspace-folder /tmp/envbuilder/vscode

Under .configuration the only new field is .configuration.configFilePath. Otherwise this is the project devcontainer.json as-is. The rest: .workspace, .featuresConfiguration and .mergedConfiguration are all added by read-configuration (and the merged config flag).

For this issue, we're mainly interested in implementing .mergedConfiguration.
