Step-by-Step n8n Deployment via Plesk Docker Extension

1. Navigating to the Docker Extension within Plesk

To begin, securely log in to your Plesk control panel using your administrative credentials. Once logged in, direct your attention to the left-hand navigation menu. Here, you will find and need to select the "Docker" option. Clicking this will seamlessly redirect you to the comprehensive Docker management interface, which is the central hub for discovering, configuring, and maintaining all your Docker images and containers.

2. Locating the Official n8n Docker Image

Once you are within the Docker interface, utilize the prominent search bar provided to efficiently locate the official n8n Docker image. Simply enter "n8n" into the search field and press the Enter key. The authenticated and recommended image is typically identified by the tag n8nio/n8n. It is important to select this specific image to ensure you are proceeding with the correct and most up-to-date version for subsequent configuration steps.

3. Meticulously Configuring the n8n Container Settings

Upon selecting the n8nio/n8n image, Plesk will present you with an interface to configure the container's operational settings. This phase is exceptionally critical as it dictates the manner in which n8n will function and interact with your server's ecosystem. Careful attention here ensures optimal performance and security.

• Automatic Startup Configuration: It is highly advisable to enable the option for "Automatic start after system reboot." This vital setting guarantees that your n8n instance will automatically relaunch and resume operations in the event of a server restart, thereby maintaining continuous availability of your automation workflows.
• Strategic Port Mapping: You will need to establish a precise mapping between a specific host port on your server and the container's internal port 5678, which is n8n's default operational port. For instance, you might choose to map host port 5678 directly to container port 5678. It is paramount to verify that the selected host port is not currently in use by any other service on your server to avoid conflicts.
• Persistent Data Volumes: The configuration of persistent data volumes is an indispensable step to safeguard your n8n data. This is absolutely crucial for the preservation of all your carefully designed workflows, configurations, and user settings. Create a designated directory on your Plesk server (e.g., /var/www/vhosts/yourdomain.com/n8n_data) and map this to the container's /home/node/.n8n directory. This robust setup guarantees that even if the Docker container itself needs to be removed or rebuilt, your invaluable data will remain entirely intact and secure.
• Essential Environment Variables: It is necessary to add several key environment variables to tailor n8n's behavior. As a minimum requirement, ensure you set N8N_HOST to reflect your domain (e.g., n8n.yourdomain.com), N8N_PORT to 5678, and GENERIC_TIMEZONE to your preferred geographical timezone (e.g., Europe/Berlin). For any production deployment, it is rigorously recommended to activate basic authentication by setting N8N_BASIC_AUTH_ACTIVE=true and subsequently defining robust N8N_BASIC_AUTH_USER and N8N_BASIC_AUTH_PASSWORD credentials.

Crucial Security Advisory: Always prioritize the use of strong, complex, and entirely unique passwords for any and all authentication credentials. Furthermore, for establishing secure and encrypted communication with your n8n instance, it is highly recommended to implement SSL/TLS encryption.

4. Executing the Deployment of the n8n Container

Once you have meticulously configured all the requisite settings for your n8n instance, the next step is to initiate the deployment. Proceed by clicking either the "Run" or "Create" button within the Plesk Docker interface. Plesk will then commence the process by first downloading the n8n Docker image (if it has not been previously cached on your server) and subsequently launching the container precisely according to the specifications you have defined. You can conveniently track the real-time progress of this deployment directly from the intuitive Docker management interface, ensuring transparency throughout the process.

5. Initial Access and Configuration of your n8n Instance

With the Docker container now actively running, your n8n instance should be readily accessible through the domain or subdomain you previously configured, combined with the mapped host port (for example, http://n8n.yourdomain.com:5678). To begin the initial setup, open your preferred web browser and navigate to this URL. The initial n8n setup typically involves a straightforward process, primarily focused on the creation of your administrative user account, which will grant you full control over your workflows.

For a significantly enhanced security posture and a more streamlined user experience, it is very highly recommended to implement a reverse proxy within Plesk. This can often be achieved efficiently through Nginx. A reverse proxy will intelligently route incoming traffic from your domain on standard HTTP and HTTPS ports (80 and 443 respectively) directly to your n8n Docker container. This critical configuration not only simplifies access but also empowers you to secure your n8n instance with a robust SSL certificate, which can be conveniently provided and managed directly through Plesk, ensuring all communications are encrypted and trustworthy.
