1. 사전 준비 사항

n8n을 Docker로 설치하기 전에 다음 사항들을 준비.

Prerequisites

To install Docker Desktop successfully, you must:

  • Meet the general system requirements.
  • Have an x86-64 system with Ubuntu 22.04, 24.04, or the latest non-LTS version.
  • If you’re not using GNOME, you must install gnome-terminal to enable terminal access from Docker Desktop:
    $ sudo apt install gnome-terminal

Install using the apt repository

Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker apt repository. Afterward, you can install and update Docker from the repository.

  1. Set up Docker’s apt repository.
    # Add Docker's official GPG key:
    sudo apt update
    sudo apt install ca-certificates curl
    sudo install -m 0755 -d /etc/apt/keyrings
    sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
    sudo chmod a+r /etc/apt/keyrings/docker.asc

    # Add the repository to Apt sources:
    sudo tee /etc/apt/sources.list.d/docker.sources <<EOF Types: deb URIs: https://download.docker.com/linux/ubuntu Suites: $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") Components: stable Signed-By: /etc/apt/keyrings/docker.asc EOF
    sudo apt update
  2. Install the Docker packages.Latest Specific versionTo install the latest version, run:
    $ sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
    Note: The Docker service starts automatically after installation. To verify that Docker is running, use:
    $ sudo systemctl status docker
    Some systems may have this behavior disabled and will require a manual start:
    $ sudo systemctl start docker
  3. Verify that the installation is successful by running the hello-world image:
    $ sudo docker run hello-world
    This command downloads a test image and runs it in a container. When the container runs, it prints a confirmation message and exits.
