The easiest supported way to run Nextcloud with Docker is Nextcloud All-in-One (AIO), which sets up Nextcloud, its database, Redis, backups and HTTPS for you.
Install Docker Engine (official repository)
Ubuntu 24.04 / Debian 12:
apt install ca-certificates curl install -m 0755 -d /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc chmod a+r /etc/apt/keyrings/docker.asc tee /etc/apt/sources.list.d/docker.sources <<EOF Types: deb URIs: https://download.docker.com/linux/ubuntu Suites: $(. /etc/os-release && echo "$VERSION_CODENAME") Components: stable Architectures: $(dpkg --print-architecture) Signed-By: /etc/apt/keyrings/docker.asc EOF apt update apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
On Debian, use https://download.docker.com/linux/debian in both the key URL and URIs.
AlmaLinux 9 / Rocky Linux 9:
dnf install dnf-plugins-core dnf config-manager --add-repo https://download.docker.com/linux/rhel/docker-ce.repo dnf install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin systemctl enable --now docker
Test with docker run hello-world. Compose is available as docker compose.
Start Nextcloud AIO
docker run --init --sig-proxy=false --name nextcloud-aio-mastercontainer --restart always \ --publish 80:80 --publish 8080:8080 --publish 8443:8443 \ --volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \ --volume /var/run/docker.sock:/var/run/docker.sock:ro \ ghcr.io/nextcloud-releases/all-in-one:latest
Open https://SERVER-IP:8080, note the passphrase shown, enter your domain (its DNS must point to the server) and let AIO start the containers.
Open the firewall
ufw allow 80,443,8080,8443/tcp # Ubuntu / Debian with UFW
firewall-cmd --permanent --add-port={80,443,8080,8443}/tcp && firewall-cmd --reload # AlmaLinux / Rocky
Nextcloud itself is served on port 443. If you enable Nextcloud Talk, also open port 3478 (TCP and UDP). After setup you can limit port 8080 to your own IP.
Tip: Plan enough disk space for your files, and enable AIO's built-in backups.
Before you start
- A VPS with at least 2 GB RAM (4 GB or more if you enable Office, Talk or full-text search) and enough disk space for your files.
- A domain or subdomain (for example
cloud.example.com) with an A record pointing to the server. - Nothing else listening on ports 80 or 443. If the server already runs a web server, follow the AIO reverse proxy documentation instead.
After installation
- Log in to Nextcloud at your domain with the admin password shown in the AIO interface.
- Update Nextcloud and all its containers from the AIO interface: it stops the containers, takes a backup if you have set one up, and starts the new versions.
- Set up the built-in backup (BorgBackup) to a separate disk or mounted storage, and test a restore.
