• Flash Raspberry Pi OS on an SD Card
• Check if RPI is working and functional

Run the following commands on raspberry pi

 $ sudo vim /boot/config.txt

• Add dtoverlay=w1-gpio on the last line of the file

 sudo reboot

• login again on to your RPI

• Look at the images provides to attach temperature sensor to RPI
• All Components for the project:
• Setup (connected components)
• Close up of sensor connection: front view
• Close up of sensor connection: rear view

Run the following commands

cd /sys/bus/w1/devices && ls
cd 28-XXXXXXXXXXX (where xxx is the file number you will see with ls)
cat temperature (this will print the temperature on terminal)

• To build the docker image from the dockerfile run the following:

  docker build -t <name-of-image> . 
  

  '.' refers to path to the docker file here assumed that docker file is in current directory

• To run the docker image making sure the volume having jenkins state (p/w's , plugins etc.) persisted run the (new) docker container as

  docker run --network="host" -v jenkins:/var/jenkins_home -it --name=<name-of-container> <name-of-image> bash
  

• To run the docker container such that the jenkins data and settings are persisted across different docker containers, first cretae a volume and then mount.

• To create the volume first run jenkins volume create jenkins where the last token, jenkins in the command above is the name of the volume where all the jenkins data is stored and persisted

• After creating the volume run the docker container by using:

  docker run --network="host" -it --mount source=jenkins,target=/var/jenkins_home -v /sys/bus/w1/devices/28-00000b65fafc:/sys/bus/w1/devices/28-00000b65fafc --name=as_rpi1 rpi2:latest bash
  

  Note: the flag -v informs jenkins to attach the path\to\sensor\data\on\rpi:as\path\to\sensor\data\in\docker\container

• Start jenkins by: java -jar /opt/jenkins.war

• Attach another bash on the container and start webhook relay as docker exec -it name_of_already_running_container bash relay login -k $RELAY_KEY -s $RELAY_SECRET relay forward --bucket github-jenkins http://ip_of_rpi:8080/github-webhook/

• Need to install HTML Publisher plugin in jenkins
• Due to security settings in jenkins the css styled pages are not displayed by jenkins as mentioned in this page https://www.jenkins.io/doc/book/system-administration/security/configuring-content-security-policy/#ConfiguringContentSecurityPolicy-HTMLPublisherPlugin
• To overcome this issue (by bypassing the security settings as mentioned in the page above) start jenkins using: java -Dhudson.model.DirectoryBrowserSupport.CSP= -jar \opt\jenkins.war
