How to Build a Zoneminder Docker Image (with MSMTP) using a Dockerfile & push to Docker Hub , (Ubuntu 19.10)

December 20, 2019

In this tutorial ,we are going to use “Docker: Enterprise Container Platform”  (docker.io) on Ubuntu 19.10.
First
Installation of Docker on Ubuntu 19.10
On the Ubuntu terminal
sudo apt install docker.io


Then a zoneminder-docker image is built using a Dockerfile and entrypoint.sh
Dockerfile contains the scripts to install free open-source  software Zoneminder and entrypoint.sh has necessary commands to start Zoneminder ,Apache and other services and to keep the docker container running.
I have used my own  Dockerfile and entrypoint.sh prepared  by Andrew Bauer
The scripts in the Docker file are as shown in the following figure:- 1

Figure:- 1 Scripts in the Dockerfile

For the purpose of building the zoneminder- docker image the files Dockerfile and entrypoint.sh are saved on the Documents  folder of the computer as shown in the following figure:- 2.

figure:- 2 Dockerfile and entrypoint.sh  marked in green color saved in the Documents folder

The Dockerfile and entrypoint.sh can be downloaded from this links

Dockerfile
entrypoint.sh

Building the Zoneminder-Docker image ( tagged as “yourzoneminder”)
Open the Ubuntu terminal

cd ~/Documents

docker build --tag=yourzoneminder . # Dockerfile
( The process will take about 10-15 minutes)
After the image building process is finished ,you find the image by runng
sudo docker images


For the purpose of  identifying the image in the Docker Hub , you will have to tag it with an appropriate name .
In our case ,I have name as “bkjaya1952/docker-zoneminder:v1.32.3.”

sudo docker tag yourzoneminder bkjaya1952/docker-zoneminder:v1.32.3.

Then push the tagged image to the Docker Hub
sudo docker login
Note : first you will have to signup & open  a Docker Hub account at https://hub.docker.com/

sudo docker push bkjaya1952/docker-zoneminder:v1.32.3.

Figure:- 3  Tagging and pushing the image to the Docker Hub

Now you can see my pushed image at  https://hub.docker.com/repository/docker/bkjaya1952/docker-zoneminder

 

Figure:-  4 Pushed image at the Docker Hub

The instructions to use the image has been entered at the Docker Hub, after the pushing is completed .

Usage of the pushed image  bkjaya1952/docker-zoneminder

sudo docker create -t -p 8085:80 --shm-size=4096m -e TZ=Asia/Colombo --name myzm --privileged=true bkjaya1952/docker-zoneminder:v1.32.3.

Note :- use your timezone instead of “TZ=Asia/Colombo”

sudo docker start myzm

Configuring MSMTP for emailing zoneminder motion detection events
Make the following file in the home folder of your computer and copy in to the zm container that you have created by above mentioned commands
Open the Ubuntu terminal and run

sudo gedit msmtprc

Then copy the following scripts with modifications to suit your gmail address and save

---

# Set default values for all following accounts.
defaults
auth on
tls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt
logfile ~/.msmtp.log

# Gmail
account gmail
host smtp.gmail.com
port 587
from youer gmail address
user youer gmail address
password your gmail password
# Set a default account
account default : gmail

---

Then copy the created msmtpru file to the folder /etc/ of the zm container as follows

sudo docker cp msmtprc myzm:/etc/msmtprc

Open http://localhost:8085/zm/ and add the camera monitors

Figure:- 5 Added USB camera to Zoneminder

And fill up email details under the Optons/email of the ZM-Panel
Create appropriate zm-filter to send email alerts of motion detection events
For entering e mail details and creating  zm-filter  please refer my following blog ( After the Figure:- 3 in the blog)
