But I failed everytime. I am trying to install it from last 3 days and every time a new problem comes up.

Also after putting command “nano containers/app.yml” for edit this file, There is no place where I can edit this file.

Docker is installed and I failed in staring this.  
Command I found for this are  
**systemctl start docker**  
**systemctl enable docker**  
But these commands are not working. it says command not found  
Every help really appreciated

CentOS has very sketchy compatibility with Docker, you should search topics here for information.
