How to Use Your Claude Code Pro Subscription in Docker (foldr.uk)

A recent guide outlines the integration of Claude Code Pro subscriptions within Docker containers, addressing a key challenge: how to maintain OAuth authentication while accommodating Claude Code's unique state storage system. Users who authenticate with OAuth can leverage their Pro subscription credits, but must navigate the complexity of Docker, which only mounts directories. This has significant implications for developers looking to run Claude Code in isolated environments, as a robust understanding and technique are needed to persist both credentials and onboarding states effectively. The guide details the necessary setup, including Dockerfile scripts to properly handle the symlink of essential files and ensuring that initialization scripts do not overwrite refreshed credentials. Users are advised to create a named volume to store the OAuth credentials while linking the onboarding state file, allowing continued access post-initial setup. This approach not only enhances the usability of Claude Code within Docker but also provides a roadmap for other applications with similarly scattered state data, promoting better containerized software practices in the AI/ML community.
