Spotify

In my previous article here, I’ve discussed how can we launch GUI Apps like Firefox Browser, Nautilus File Manager in Docker.

Today, I’m again with another GUI App in Docker container, Spotify.

For a GUI Application to run, we need to have an XServer which is available as part of every Linux Desktop Environment.

For Windows, you can use Xming.

For OSX, you can use Xquarkz.

What is Docker?

Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and deploy it as one package. By doing so, thanks to the container, the developer can rest assured that the application will run on any other Linux machine regardless of any customized settings that the machine might have that could differ from the machine used for writing and testing the code.

In a way, Docker is a bit like a…

The Hadoop Distributed File System (HDFS) is a distributed file system designed to run on commodity hardware. It has many similarities with existing distributed file systems. However, the differences from other distributed file systems are significant. HDFS is highly fault-tolerant and is designed to be deployed on low-cost hardware. HDFS provides high throughput access to application data and is suitable for applications that have large data sets.

By default, Hadoop Slave Nodes/ Data Nodes contributes all the storage present in the “/” (root drive) to the Hadoop Cluster. E.g., …
