In case to use ssh-keys device access in docker you need to export the keys from the Docker host to make them persistent.

Docker run

1. Put the keys into /var/xormon-ng/ssh-keys on the Docker host and make sure rights are correct

   ls -la  /var/xormon-ng/ssh-keys
     drwx------   2 root root   76 Jan 30  2023 .
     dr-xr-x---. 26 root root 4096 Jan 17 12:34 ..
     -rw-------   1 root root  419 Jan 17 12:34 id_ed25519
     -rw-r--r--   1 root root  104 Jan 17 12:34 id_ed25519.pub
   

2. Test connection to the device, user your own device user and hostname/IP

   ssh -i  /var/xormon-ng/ssh-keys/id_ed25519 <device user>@<device IP/hostname>
   

3. Map /var/xormon-ng/ssh-keys to /root/.ssh/ into the container as per bellow
   

   docker run --init -d --name xormon --ulimit core=0 -p 8443:8443 \
   -v /var/xormon-ng/files:/app/server-nest/files \
   -v /var/xormon-ng/ssh-keys:/root/.ssh \
   --link timescaledb:timescaledb --env-file ./xormon-ng.env xorux/xormon-ng:latest

Docker compose

1. Put the keys into the directory ./ssh-keys where is docker-compose.yml on the Docker host and make sure rights are correct

   ls -la  ./ssh-keys
     drwx------   2 root root   76 Jan 30  2023 .
     dr-xr-x---. 26 root root 4096 Jan 17 12:34 ..
     -rw-------   1 root root  419 Jan 17 12:34 id_ed25519
     -rw-r--r--   1 root root  104 Jan 17 12:34 id_ed25519.pub
   

2. Test connection to the device, user your own device user and hostname/IP

   ssh -i  ./ssh-keys/id_ed25519 <device user>@<device IP/hostname>
   

3. Map ./ssh-keys to /root/.ssh/ into the container as per bellow
   

   services:
     timescaledb:
       image: timescale/timescaledb:latest-pg16
       init: true
       restart: unless-stopped
       ulimits:
         core: 0
       environment:
         - POSTGRES_USER=${DB_USERNAME}
         - POSTGRES_PASSWORD=${DB_PASSWORD}
         - TZ=${TZ}
       volumes:
         - ./data:/var/lib/postgresql/data
       ## uncomment if you want to have Postgres (TSDB) port opened on host
       # ports:
       #  - '5432:5432'
     xormon:
       image: xorux/xormon-ng:latest
       init: true
       restart: unless-stopped
       ulimits:
         core: 0
       depends_on:
         - timescaledb
       env_file: .env
       volumes:
         - ./files:/app/server-nest/files
         - ./ssh-keys:/root/.ssh
       ports:
         - ${APP_PORT}:${APP_PORT}
         - 8162:8162
