Key Features of Docker - Exploring top 10 features of Docker
Docker provides lots of features. These slew of interesting features have made the platform much attractive to the users . Some are so exquisite that drags the attention of the developers in no time. Many of these features are likely to explain the key reasons behind the popularity of Docker technology.
Now, let's examine the key features one by one.
1. Configure easily in less time
This is a developer- friendly feature of Docker. It helps an user to configure the system easily and gifts a faster application time.
One can deploy the code in less time and without any complication . Docker can operate in a wide variety of environments,. This indicates that the requirements of the infrastructure are independent of the environment of the application.
2. Productivity is high
It offers an increased level of productivity because of its easing of technical configuration and a fast deployment of application.Docker helps the application to be functional in isolated environment . it has reduced the exploitation of resources.
3. Unique Application Isolation
Docker containers are used to run applications in isolation environment. Since each container is independent to another it allows to execute any kind of application.
4. Swarm
Docker containers enjoy a clustering and scheduling tool called Swarm.It uses the Docker API as its front end. This characteristic of the platform opens the opportunity to use various tools to control it. It also gives the user a benefit to control a cluster of Docker hosts as a single virtual host. This is featured as a self-organizing group of engines which is effective in enabling pluggable backends.
5. Routing Mesh
It routes requests to a container for published ports on available nodes . Even if there is no task is running on the node the connection remains active for the feature.
6. Excellent services
To understand the state of the container inside a cluster, Services reveals a list of tasks . Each task caters to one instance of a container and should be running . The job of Swarm is to schedule them across nodes.
7. Security Management
This feature operates to save secrets into the swarm itself . It also chooses to give services access to certain secrets. It supplies some important commands to the engine like Secret inspect, Secret create etc.
8. Easily scalable
Since the Docker containers are lightweight, the platform earns an easy scalability.
9. Reduction in infrastructure and maintenance cost
Docker offers immediate value to the business by decreasing the cost of infrastructure and maintenance of the existing application portfolio.
10. Ability to reduce the size
Docker has a high degree of ability to reduce the size of the development. The reason is , it can provide a smaller footprint of the operating system via containers.
Conclusion
This vivid introspection of these top 10 Docker features has unveiled the fact why this platform stands out from the crowd and has earned enormous popularity. However, Docker is an ever-evolving pathway. More magic is waiting at the doorstep to make it more spectacular.
