--- #https://www.notion.so/n8n/Frontmatter-432c2b8dff1f43d4b1c8d20075510fe4 contentType: tutorial --- # Docker Installation [Docker](https://www.docker.com/){:target=_blank .external-link} offers the following advantages: * Installs n8n in a clean environment. * Easier setup for your preferred database. * Can avoid issues due to different operating systems, as Docker provides a consistent system. * Can avoid compatibility issues due to differences in operating systems and tools. * Makes migrating to new hosts or environments more straightforward. You can also use n8n in Docker with [Docker Compose](/hosting/installation/server-setups/docker-compose.md). You can find Docker Compose configurations for various architectures in the [n8n-hosting repository](https://github.com/n8n-io/n8n-hosting). --8<-- "_snippets/self-hosting/warning.md" ## Prerequisites Before proceeding, install [Docker Desktop](https://docs.docker.com/get-docker/){:target=_blank .external-link}. /// note | Linux Users Docker Desktop is available for Mac and Windows. Linux users must install [Docker Engine](https://docs.docker.com/engine/install/) and [Docker Compose](https://docs.docker.com/compose/install/) individually for your distribution. /// --8<-- "_snippets/self-hosting/installation/latest-next-version.md" ## Starting n8n From your terminal, run: ```sh docker volume create n8n_data docker run -it --rm --name n8n -p 5678:5678 -v n8n_data:/home/node/.n8n docker.n8n.io/n8nio/n8n ``` This command creates a volume to store persistent data, downloads the required n8n image, and starts your container, exposed on port `5678`. To save your work between container restarts, it also mounts a docker volume, `n8n_data`, to persist your data locally. Once running, you can access n8n by opening: [http://localhost:5678](http://localhost:5678) ## Using with PostgreSQL By default, n8n uses SQLite to save [credentials](/glossary.md#credential-n8n), past executions, and workflows. n8n also supports PostgreSQL, configurable using environment variables as detailed below. When using PostgreSQL, it's still important to persist the data stored in the `/home/node/.n8n` folder. This includes n8n user data and, even more importantly, the encryption key for credentials. It's also the name of the webhook when using the [n8n tunnel](#n8n-with-tunnel). If n8n can't find the `/home/node/.n8n` directory on startup, it automatically creates one. In this case, all existing credentials that n8n saved with a different encryption key will no longer work. /// note | Keep in mind While persisting the `/home/node/.n8n` directory with PostgreSQL is the recommended best practice, it's not explicitly required. You can provide the encryption key by passing the [`N8N_ENCRYPTION_KEY` environment variable](/hosting/configuration/environment-variables/deployment.md) when starting your Docker container. /// To use n8n with PostgreSQL, execute the following commands, replacing the placeholders (depicted within angled brackets, for example ``) with your actual values: ```sh docker volume create n8n_data docker run -it --rm \ --name n8n \ -p 5678:5678 \ -e DB_TYPE=postgresdb \ -e DB_POSTGRESDB_DATABASE= \ -e DB_POSTGRESDB_HOST= \ -e DB_POSTGRESDB_PORT= \ -e DB_POSTGRESDB_USER= \ -e DB_POSTGRESDB_SCHEMA= \ -e DB_POSTGRESDB_PASSWORD= \ -v n8n_data:/home/node/.n8n \ docker.n8n.io/n8nio/n8n ``` You can find a complete `docker-compose` file for PostgreSQL in the [n8n hosting repository](https://github.com/n8n-io/n8n-hosting/tree/main/docker-compose/withPostgres). ## Setting timezone To define the timezone n8n should use, you can set the [`GENERIC_TIMEZONE` environment variable](/hosting/configuration/environment-variables/timezone-localization.md). Schedule-oriented nodes, like the [Schedule Trigger node](/integrations/builtin/core-nodes/n8n-nodes-base.scheduletrigger/index.md) use this to determine the correct timezone. You can set the system timezone, which controls what some scripts and commands like `date` return, using the `TZ` environment variable. This example sets the same timezone for both variables: ```sh docker volume create n8n_data docker run -it --rm \ --name n8n \ -p 5678:5678 \ -e GENERIC_TIMEZONE="Europe/Berlin" \ -e TZ="Europe/Berlin" \ -v n8n_data:/home/node/.n8n \ docker.n8n.io/n8nio/n8n ``` ## Updating To update n8n, in Docker Desktop, navigate to the **Images** tab and select **Pull** from the context menu to download the latest n8n image: ![Docker Desktop](/_images/hosting/installation/docker/docker_desktop.png) You can also use the command line to pull the latest, or a specific version: ```sh # Pull latest (stable) version docker pull docker.n8n.io/n8nio/n8n # Pull specific version docker pull docker.n8n.io/n8nio/n8n:1.81.0 # Pull next (unstable) version docker pull docker.n8n.io/n8nio/n8n:next ``` After pulling the updated image, stop your n8n container and start it again. You can also use the command line. Replace `` in the commands below with the container ID you find in the first command: ```sh # Find your container ID docker ps -a # Stop the container with the `` docker stop # Remove the container with the `` docker rm # Start the container docker run --name= [options] -d docker.n8n.io/n8nio/n8n ``` ### Updating Docker Compose --8<-- "_snippets/self-hosting/installation/docker-compose-updating.md" ## Further reading You can find more information about Docker setup in the README file for the [Docker image](https://github.com/n8n-io/n8n/tree/master/docker/images/n8n). --8<-- "_snippets/self-hosting/installation/tunnel.md" Start n8n with `--tunnel` by running: ```sh docker volume create n8n_data docker run -it --rm \ --name n8n \ -p 5678:5678 \ -v n8n_data:/home/node/.n8n \ docker.n8n.io/n8nio/n8n \ start --tunnel ``` ## Next steps --8<-- "_snippets/self-hosting/installation/server-setups-next-steps.md"
