1.Create a file in the /tmp folder
script_one.sh and script_two.sh
2. Give appropriate permissions to run
sudo chmod +x script_one.sh
sudo chmod +x script_two.sh
3. run the file 1
./script_one.sh
4. Reboot to apply permissions
5. . run the file 2
./script_two.sh

In case of any errors or if docker is not running, try to set environment variables and try to run the docker again.
