Difference between Jenkins and Docker
Jenkins:-
Jenkins is an open-source non-stop integration server written in java for orchestrating a sequence of actions to attain the continuous integration technique in an automated style. Jenkins helps the complete improvement lifestyles cycle of software program from constructing, testing, documenting the software program, deploying, and different stages of the software improvement existence cycle.
Docker:-
Docker is an open-source containerization platform. It enables developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment. Containers simplify the delivery of distributed applications and have become increasingly popular as organizations shift to cloud-native development and hybrid multi-cloud environments.
Advantages of Jenkins and Docker:-
Below mentioned are some of the benefits of Jenkins:
Jenkins is quite suitable for start-ups as it is completely open-source.
It can be modified as per requirement.
Plugins can be created if one is not available.
It is very adaptable as it allows deploying and automating in different parts with the help of its huge plugin system.
It is easy to install.
Some of the benefits of Docker are as below:
Easily portable, as after testing, the containerized applications can be deployed to other systems where Docker is running.
It is secured as it gives us complete control over the traffic flow of isolated containers.
It is light, as Docker images are typically small and therefore deployed rapidly, saving a lot of time.
Developers, with the help of Docker, can use multiple versions of the same programming languages.
Promotes standardization for businesses through its consistency in deployment processes and release cycles.
It is entirely scalable as new containers can be created if the application demands them.
Disadvantages of Jenkins and Docker:-
Below mentioned are some of the disadvantages of Jenkins:
Jenkins is unable to follow the Salesforce metadata type.
It doesn’t provide visibility into end-to-end metrics.
Customers often face issues related to tracking of changes made by the developer teams.
Since the majority of deployments done by Jenkins happen via single user, tracking deployments becomes difficult.
To minimize system failures, sandboxes are used by a majority of organizations. Jenkins does not provide any supportive frameworks to manage these sandboxes.
Some of the cons of Docker have been explained below:
Data storage is an issue as data inside a container can get erased if the container shuts down.
Speed issues happen as containers consume more resources than virtual machines. If a user is expecting 100 percent bare-metal performance, they need to use bare metals, not containers.
Docker is platform-dependent as it uses virtual machines to run on non-Linux platforms.
Data collection in real-time is more challenging in Docker as the stats command will give you information related to containers, but the same might not help in advanced stages.
