For years, software developers sought alternative ways of deploying applications across different operating systems. The dual-boot technology came along. Then, machine virtualization had beckoned. But these technologies were very expensive in terms of resources. Until five years ago, Solomon Hykes founded Docker, which sought to make containers easy to use and solve this problem.
As a worldwide initiative, the Docker Community in Buea, on March 31, 2018 celebrated its 5th birthday at Makonjo Media, a Silicon Mountain-based marketing and growth technology firm.
According to Larry Ivange, the coordinator of the Docker Community in Buea, the event was essentially a training session to introduce and educate software developers within the Silicon Mountain on how Docker works.
“Docker communities all over the world have regular meetups to train developers on the use of the container technology, especially docker. A lot of companies are starting to use docker and having containers on their portfolio, gives them a lot of credibility,” Larry stated.
The platform has a strong community of developers that organizes #meetups in various cities across the world.
During this event, the Buea community welcomed newcomers into the Docker community. They provided training to show developers how to build, ship, and run a distributed application with ease, thanks to the Docker platform.
Docker is the original author and primary sponsor of the Docker open-source project. Together with the community of maintainers and contributors, it aims to deliver open tools to help developers build applications with open APIs to help sysadmins better manage these applications.
Docker makes it easier for developers to create, deploy, and run applications by using containers. These containers allow developers to package an application with all of the parts it needs: libraries and other dependencies, and ship it all out as one package.
By doing so, developers can rest assured that the application will run on any other system, regardless of any pre-configured settings that system might have that could differ from the system used to write and test the code.
Training sessions centered around introducing developers to Docker on both the Linux and Windows operating systems. These sessions took them through the basics of the platform. It ranged from building containers to deploying multi-OS applications with Docker to using the raspberry pi to develop complex applications.
The Docker software is developed by Docker Inc, a US-based firm established in 2013.Its aim, to perform operating-system-virtualization or containerization. It has since grown to become the most widely used containerization platform for software developers.
Future of Docker and containerization platforms
Over the years, containers have become the fastest-growing cloud enabling technology. By 2020, more than 50% of global organizations will run containerized applications in production, up from less than 20% currently.
So far, 3.5 million applications have been placed in containers using Docker technology and over 37 billion containerized applications downloaded.
Using containers can help enterprises modernize legacy applications and create new cloud-native applications that are both scalable and agile. Container frameworks, such as Docker, provide a standardized way to package applications. This includes the code, runtime and libraries — and to run them across the entire software development lifecycle.
However, the current container ecosystem is immature. Organizations, therefore, have to develop more solid business cases needed for the additional costs for deploying containers in production. Organizing training events such as these is one of the ways Docker intends to push through and promote containerization globally.
