First try to run Openhab in a docker on Ubuntu

Setup, Configuration and Use Beginners
31

I finally have everything working as I wanted. This means Ubuntu, Docker, Openhab, access from windows and backup to synology. Thanks to the people who provided feedback on my questions.

If interested find below the steps I used

Install Ubuntu and the additional fixes (takes a few minutes before it popup)

  • Install docker from App Center

  • Running Docker as normal user
    sud add group --system docker
    sud adducer $USER docker
    newsgroup docker

sudo snap disable docker

sudo snap enable docker

  • Install openhab by creating the required directories
    mkdir -p /home/mynuc/docker/openhab4.1.1/addons
    mkdir -p /home/mynuc/docker/openhab4.1.1/conf
    mkdir -p /home/mynuc/docker/openhab4.1.1/userdata

  • Give the folder and the sub-folders al rights
    cd /home/mynuc/docker
    sudo chmod -R a+rwx .

  • Create yaml docker compose file
    cd /home/mynuc/docker
    nanu docker-compose.yml

  • Add the following lines

services:
openhab:
image: "openhab/openhab:4.1.1"
restart: always
network_mode: host
volumes:
- "/etc/localtime:/etc/localtime:ro"
- "/etc/timezone:/etc/timezone:ro"
- "/home/mynuc/docker/openhab4.1.1/addons:/openhab/addons"
- "/home/mynuc/docker/openhab4.1.1/conf:/openhab/conf"
- "/home/mynuc/docker/openhab4.1.1/userdata:/openhab/userdata"
environment:
CRYPTO_POLICY: "unlimited"
EXTRA_JAVA_OPTS: "-Duser.timezone=Europe/Amsterdam"
OPENHAB_HTTP_PORT: "8080"
OPENHAB_HTTPS_PORT: "8443"

  • Run docker compose up -d

  • Check if you can access openhab with localhost and/or ip address on port 8080.

Share Openhab folders with Windows (I use VSC under windows)

  • Install samba
    sudo apt install samba

  • Configure samba what folder to share
    sudo nano /etc/samba/smb.conf
    The name between is the name popin-up in windows

[Docker_nuc]
path = /home/mynuc/docker
read only = No
guest ok = Yes
force user = mynuc

  • Restart the samba service
    sudo service smbd restart

  • Make it a network drive for windows
    sudo apt install wsdd

  • Check windows network
    You should be able to select the docker folder without login

  • I want to backup all the folders from Openhab in a tar file on Synology
    *The steps on Synology are straight forward

  • Map a shared folder from the Synology with the NUC
    You should see NAS. Select the first option and login with your Synology credentials.

  • Now you should see the NAS

  • Install NFS
    sudo apt-get install nfs-common -y

  • Create a backup folder in the /srv folder. This seems to be important
    sudo mkdir /srv/backup_nas

  • Map both folders in a boot persistence way
    sudo nano /etc/fstab

192.168.100.51:/volume1/backup_nuc /srv/backup_nas      nfs     defaults        0       0

  • Reload the deamon
    systemctl -q daemon-reload

  • Mount the folder
    sudo mount -a

  • Create a backup script what you can use with crown
    Go to the docker folder
    cd /home/mynuc/docker
    Create the backup scripts file
    nanu backup.sh

echo "Backing up openhab 4.1.1"
file=/srv/backup_nas/openhab-$(date +%Y-%m-%d_%H%M).tgz
cd /home/mynuc/docker/openhab4.1.1
tar cfz $file .
  • Test the backup
    sudo bash /home/mynuc/docker/backup.sh
  • Change the rights to run it as root
    sudo chmod u+s backup.sh
  • Create a cron job for call the backup script file
    sudo crontab e
35 16 * * * sudo bash /home/mynuc/docker/backup.sh
  • Restart
    sudo systemctl restart cron
  • Check if the jobs work after time is expired with
    systemctl status cron
