tomsquest/docker-radicaleWhat is Docker-Radicale?
Docker-Radicale is a hardened Docker image for the Radicale CalDAV/CardDAV server. It provides a production-ready container that runs as a non-root user with read-only filesystem, dropped capabilities, and resource limits. The image supports both amd64 and arm64 architectures, includes git and SSH for versioning, LDAP authentication support, and bcrypt/argon2 password hashing. Configuration can be done via environment variables (RADICALE_CONFIG_*) or a custom config file. It offers multiple options for handling file permissions on mounted volumes. The image is built daily from Alpine Linux for security patches and version tags follow the Radicale version plus an image revision number.
