In this guide, you\u2019ll learn how to deploy n8n<\/strong> on a VPS from Unihost<\/strong> (UNH series) with PostgreSQL, running behind the Traefik reverse proxy<\/strong>.<\/span>
The setup will automatically issue and renew HTTPS certificates using Let\u2019s Encrypt<\/strong>.
<\/span>Everything will be managed from a single directory, and the whole deployment will run with just one command.<\/span><\/p>\n

Why this guide skips Docker installation<\/span><\/h2>\n

Our Unihost VPS (UNH model) already includes Docker, so there\u2019s no need to install it separately.<\/span>
When ordering a VPS, you can also select an operating system image with Docker pre-installed \u2014 simply choose the appropriate OS in the configurator, and your server will be ready for immediate use.<\/span><\/p>\n

\"Deploying<\/p>\n

Prerequisites<\/b><\/span><\/h3>\n
DNS:<\/b> Create an A-record like:
<\/span><\/span>n8n.<your_domain><\/span> \u2192 <\/span><your server\u2019s public IP><\/span><\/span><\/h6>\n

Ports:<\/b> Make sure ports <\/span>80\/tcp<\/b> and <\/span>443\/tcp<\/b> are open on your server.<\/span><\/span><\/p>\n

Create the directory and the <\/b>.env<\/b> file<\/b><\/span><\/p>\n

mkdir -p ~\/n8n-stack && cd ~\/n8n-stack<\/span>

nano .env<\/span><\/pre>\n
Paste the following content into the <\/span>.env<\/span> file, and <\/span>make sure to replace <\/b>DOMAIN<\/b>, <\/b>ACME_EMAIL<\/b>, and all passwords <\/b><\/span>with your own secure values:<\/span><\/span><\/p>\n

    Why this setup works well:<\/b><\/span><\/p>\n
      \n
    • A fixed network name <\/span>proxy<\/span> is defined so that Traefik and n8n can reliably communicate with each other.<\/span>
      <\/span><\/span><\/li>\n
    • env_file: .env<\/span> is used for both <\/span>postgres<\/span> and <\/span>n8n<\/span> containers \u2014 this ensures all environment variables from the <\/span>.env<\/span> file are injected into the containers.<\/span>
      <\/span><\/span><\/li>\n
    • Port <\/span>5678<\/span> of the <\/span>n8n<\/span> container is <\/span>not exposed to the outside<\/b> \u2014 access is only allowed through Traefik over HTTPS.<\/span>
      <\/span><\/span><\/li>\n
    • The label <\/span>traefik.docker.network=proxy<\/span> explicitly tells Traefik which network to use when connecting to <\/span>n8n<\/span>, which is necessary if the container is attached to multiple networks.<\/span><\/span><\/li>\n<\/ul>\n
      Step 3. Launch<\/strong><\/span><\/p>\n
      \n
      docker compose up -d <\/span><\/pre>\n<\/div>\n
      Wait about 10\u201360 seconds<\/strong>: n8n will run the database migrations, and Traefik, on the first access to the domain, will request a Let\u2019s Encrypt certificate. Within a couple of minutes, your certificate should be active.<\/span>
      If the certificate is still inactive after a few minutes, your browser may have cached the page. Try opening n8n in Incognito\/Private mode<\/strong>.<\/span><\/p>\n
      Quick Summary<\/b><\/span><\/p>\n
      After completing these steps, you’ll have a fully functional n8n instance with a PostgreSQL database and automatic HTTPS via Traefik.<\/span><\/p>\n
      This setup is convenient because:<\/span><\/p>\n
        \n
      • Everything is managed with a single command: <\/span>docker compose up -d<\/span>
        <\/span><\/span><\/li>\n
      • Traefik automatically issues and renews Let\u2019s Encrypt certificates.<\/span><\/span><\/li>\n
      • The database is isolated and accessible only to the <\/span>n8n<\/span> container<\/span>
        <\/span><\/span><\/li>\n
      • You can easily add more services behind Traefik on different subdomains<\/span><\/li>\n<\/ul>\n\n\n
