1st Docker installation (Debian)

1.1 Uninstall old versions

sudo apt-get remove docker docker-engine docker.io containerd runc

1.2 Repo installation

1.2.1 Update apt and activate HTTPS

 sudo apt-get update
 
 sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release
 
sudo mkdir -m 0755 -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
 

1.2.2 Add Docker GPG Key

sudo mkdir -m 0755 -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

1.2.3 Repo setup

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

1.3 Install Docker Engine

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

2. install Docker Compose

sudo apt-get install docker-compose-plugin

3. DNS entry

Type: A

5. create .env file

/somedirectory/n8n/.env
# Folder where data should be saved
DATA_FOLDER=/root/n8n/
 
# The top level domain to serve from
DOMAIN_NAME=example.com
 
# The subdomain to serve from
SUBDOMAIN=n8n
 
# DOMAIN_NAME and SUBDOMAIN combined decide where n8n will be reachable from
# above example would result in: https://n8n.example.com
 
# The user name to use for authentication - IMPORTANT ALWAYS CHANGE!
N8N_BASIC_AUTH_USER=user
 
# The password to use for authentication - IMPORTANT ALWAYS CHANGE!
N8N_BASIC_AUTH_PASSWORD=password
 
# Optional timezone to set which gets used by Cron-Node by default
# If not set New York time will be used
GENERIC_TIMEZONE=Europe/Berlin
 
# The email address to use for the SSL certificate creation
SSL_EMAIL=user@example.com

6. create data directory

mkdir /somedirectory/n8n

7. start and stop

7.1 Start

sudo docker compose up -d

7.1.1 Start with output

sudo docker compose up

7.2 Stop

sudo docker compose stop

8 Update

8.1 Update image

docker pull n8nio/n8n

8.2 Restart

# Stop current setup
sudo docker compose stop
# Delete it (will only delete the docker-containers, data is stored separately)
sudo docker compose rm 
# Then start it again, in ingteractive mode to check for errors
sudo docker compose up

If everything runs without errors, end the process with CTRL+C and start it in daemon mode 

sudo docker compose up -d
