docker-nextcloudcmd-client

A Dockerized Nextcloud command-line client (nextcloudcmd) to sync from any supported Nextcloud(-like) environment.
This container should work with:

• Any standard Nextcloud server
• TransIP STACK
• Other compatible WebDAV-based Nextcloud-like storage platforms

⚠️ This project is only tested with TransIP's STACK.

This project is a continuation of docker-nextcloudcmd-client to use Nextcloud instead of ownCloud.

Use Case

This container is designed to continuously synchronize files from a remote Nextcloud(-like) storage to your local machine via Docker.
Example use case: You have a remote cloud account (e.g., your friend's Nextcloud or a TransIP STACK instance), and you want that data synced to your server via Docker.

Docker Features

• Base: Debian 12
• Image Size: <150MB
• Folder-specific sync support
• Built with Unraid compatibility in mind

Run container from Docker registry

The container is available from the Docker registry and this is the simplest way to get it.

             -e NEXTCLOUD_USER=nextcloud_username \
             -e NEXTCLOUD_PASS=nextcloud_password \
             -e NEXTCLOUD_SERVER=mynextcloud.com \
