Roadmap

Dev Container compatibility is the primary milestone. This checklist tracks complete, compatibility-tested behavior. Prototype support — the parts described on the Dev Containers page that already work in 0.1.x — does not count as complete, so items stay unchecked until their semantics and real-world compatibility have been validated.

That is why almost everything below is unchecked even though the code already does much of it. The checklist is a compatibility contract, not a progress bar.

Core

• Discover .devcontainer/devcontainer.json
• Discover .devcontainer.json
• Discover .devcontainer/<folder>/devcontainer.json
• Parse JSONC and validate the Dev Container configuration
• Environment-variable substitution
• Deterministic workspace/container naming

Dev Container compatibility

• image
• build
• Dockerfile-based environments through Podman
• containerEnv
• remoteEnv
• mounts
• workspaceMount
• workspaceFolder
• containerUser
• remoteUser
• forwardPorts
• portsAttributes
• features
• customizations
• Full Dev Container variable substitution

Lifecycle

• initializeCommand
• onCreateCommand
• updateContentCommand
• postCreateCommand
• postStartCommand
• postAttachCommand
• Lifecycle command execution and ordering
• Workspace start, stop, delete, and status
• Interactive exec/SSH into a workspace
• Persistent named volumes

Local Podman

• Local Podman workspace creation

SSH/Remote Podman

• Remote Podman workspace creation over system SSH
• Clone and reuse a remote Git workspace source
• Synchronize a local project directory to a remote host

Compatibility and testing

• Unit coverage without requiring Podman or SSH
• Compatibility testing against real-world .devcontainer configurations

Out of scope

These are not unchecked items — they are decisions. See About.

• Kubernetes and cloud provider backends
• Docker as a container runtime
• A generic provider or plugin ecosystem
• Machine provisioning, IDE management, and agent orchestration
