The beauty of Docker is that you can run a very lightweight image of another Linux distro on your host system.  In this post we will be pulling the latest image of CentOS into our docker container on our Ubuntu server. Step-by-Step: 1. Open the terminal in Ubuntu, then make sure docker is running by typing service docker status, you should see something a message like the image below

One of the most common task you have to do as a Linux administrator is to add a new user.  Especially developers who always wants root access. Docker needs root access, however the person who is administering Docker is probably not the system administrator.  Most likely it will be the application developer. To accomplish this task you can use the useradd command in the Terminal session then add the new user to the Docker group.  Follow the steps below to add a new user to Ubuntu. 1.  Switch into the root user using  sudo su -  command

In ASP.NET MVC there is a default layout file that the application use when one exists.  If you look at the markup at the top of the "Index.cshtml" file you will see that there is a markup to specify the layout of the page in the code below. @{ Layout = null; } The code above tells ASP.NET MVC to not assign any layout to the page because it is being set to null. In this blog we will build on our existing NorthwindCafe.Web    project and add a default layout view to the project so that each page in the project will have a common layout.  This is similar what you would a master page for in web forms.

In the previous post we installed Docker on our Ubuntu server.  Now we are going to add the Docker repository to our local server so that we can get the latest version of Docker. Step-By-Step Instructions: Open the terminal command line tool and switch to root user with the sudo su command 2. Now we have to add the Docker repo key to our local machine by typing the following command wget -qO- https://get.docker.com/gpg | apt-key add - 3. The next command is to add the Docker repository to the Ubuntu repository source list.  Type the following command into the terminal: echo deb http://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list 4.  Now type apt-get update to get the latest updates from the Docker repository.  If you haven't ran update for a while.  This might take a while. 5.  After the update has completed type docker -v to the version number

Docker is the hottest infrastructure technology to hit the tech world in a long time.  The appeal of Docker is that it allows the infrastructure team to utilize the capacity of the servers to near full capacity.  Docker is a container.  A container is like a micro virtualization minus the operating system.  It only contains enough infrastructure to host an app, without the fat.  Hence the term container is used to describe it. Here are the steps to install Docker on a CentOS Server: 1.  Open the CentOS terminal, then type the following command to switch to the super user:       sudo su 2.  Now get the latest update for CentOS by typing yum update 3.  To install Docker type the following command in the terminal     yum install -y docker 4.  Once the installation is complete type following command to start the docker service       systemctl start docker.service , then type systemctl status docker.service to see the current status      of our docker container.  You should see the message
