n8n

Docker apparently won't populate the volume if it's a local bind giving a "Error: Command "start" not found"

For the first time I created the docker volume then manually copied out the contents. This should not be necessary anymore.

mkdir -p /mnt/storage5/data/docker/n8n

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

docker volume inspect n8n_data

sudo rsync -avP /var/lib/docker/volumes/n8n_data/_data/ /mnt/storage5/data/docker/n8n/

In order to allow connections from the network:

N8N_SECURE_COOKIE to false

N8N_BASIC_AUTH_ACTIVE=trueand then add the user and password you want for N8N_BASIC_AUTH_USER andN8N_BASIC_AUTH_PASSWORD

How to install n8n:

docker run -it --rm \

 --name n8n \
 -p 5678:5678 \
 --network host \
 -v /mnt/storage5/data/docker/n8n:/home/node/.n8n \
 -e N8N_SECURE_COOKIE=false \
 -e N8N_BASIC_AUTH_ACTIVE=true \
 -e N8N_BASIC_AUTH_USER=hegemon \
 -e N8N_BASIC_AUTH_PASSWORD=nopassword \
 -e N8N_RUNNERS_ENABLED=true \

Gogs

docker run --name=gogs \
       --hostname=a6085e10821c \
       --mac-address=02:42:ac:11:00:02 \
       --volume /backup \
       --volume /mnt/storage5/data/gogs:/data \
       --network=bridge \
       --workdir=/app/gogs \
       -p 10022:22 \
       -p 10080:3000 \
       --restart=always \
       --log-driver=journald \
       --runtime=runc \
       --detach=true \
       gogs/gogs:0.12 \
       /bin/s6-svscan /app/gogs/docker/s6/

Not sure what that executable is? The latest version of gog's 0.13 has an issue....
