The DevOps pipeline is a sequence of steps that software development and deployment teams use to move code from idea to production.
Developing the perfect software or app is critical for any business. In order to improve the efficiency and reliability of this process, many organizations are turning to containers. Containers offer several advantages over traditional methods of deploying software, including portability, flexibility, and scalability.
JFrog is a leading provider of container management solutions. In this post, we’ll explore the role that containers can play in the DevOps pipeline, and how you can make the most out of them.

Understanding DevOps
The term “DevOps” is a combination of the words “development” and “operations.” It refers to the practice of combining these two traditionally separate functions in order to speed up the software development lifecycle.
In a traditional organization, development and operations teams work independently of each other. Development teams are responsible for writing code, while operations teams are responsible for deploying and maintaining it. This can lead to silos and inefficiencies.
The DevOps approach is designed to address these issues. In a DevOps organization, development and operations teams work together from the beginning to the end of the software development lifecycle. This allows for more collaboration and communication, and can help to speed up the process.
There are a number of DevOps practices that can be used to achieve these goals, including continuous integration (CI), continuous delivery (CD), and Infrastructure as Code (IaC).
What Are Containers?
Containers are a type of software packaging that isolates an application or service from its surrounding environment. This makes it possible to run the same application or service on different machines without having to worry about compatibility issues.
Containers are often compared to virtual machines (VMs), but there are some key differences between the two. VMs include a complete copy of an operating system, while containers share the kernel of the host operating system, making containers much lighter and more portable than VMs.
Another key difference is that VMs are designed to run a single application, while containers can run multiple applications or services. Ultimately, this makes containers more flexible and scalable than VMs.
Containers and the DevOps Pipeline
One of the most popular DevOps tools is containers. Containers can be used in a number of different ways to improve the efficiency of the DevOps pipeline.
For example, containers can be used for continuous integration and delivery (CI/CD). In CI/CD, code changes are automatically built, tested, and deployed to production. This can help to speed up the software development lifecycle and reduce errors.
Containers can also be used for infrastructure as code (IaC). IaC is a practice in which infrastructure is provisioned and managed using code, rather than manual processes. IaC can help in improving the speed and stability of deployments.
Why Use Containers in the DevOps Pipeline?
There are several reasons why you might want to use containers in the DevOps pipeline. These include:
Portability
First, containers are portable, which means they can be easily moved from one environment to another. This is helpful when you need to deploy software to multiple environments, such as development, staging, and production.
Flexibility
Second, containers are flexible. Flexibility means they can be used for a variety of purposes, such as microservices, continuous integration and delivery (CI/CD), and even serverless architecture.
Scalability
Finally, containers are scalable. This means that you can easily add or remove containers as needed, without having to worry about compatibility issues.
How To Use Containers in the DevOps Pipeline
Now that we’ve covered some of the benefits of using containers in the DevOps pipeline, let’s take a look at how you can actually use them.
1. Microservices
One common way to use containers is for microservices. Microservices are small, independent services that work together to form a larger application.
By packaging each service in its own container, you can easily update and deploy each service independently. This makes it easier to manage complex applications, and also makes it possible to scale individual services as needed.
2. CI/CD
Another common use for containers is CI/CD pipelines. A CI/CD pipeline automates the process of software development and deployment.
Typically, a CI/CD pipeline will build, test, and deploy code automatically. By packaging your application in a container, you can easily move it through the CI/CD pipeline without having to worry about compatibility issues.
3. Serverless Architecture
Finally, containers can also be used for serverless architecture. This is a type of architecture that allows you to run code without having to provision or manage servers.
Instead, your code is executed in response to events, such as an HTTP request, which can be helpful when you want to scale your application quickly and efficiently.
Conclusion
Containers can play a valuable role in the DevOps pipeline by providing portability, flexibility, and scalability. By using containers, you can easily deploy software to multiple environments, automate the software development and deployment process, and even scale your application quickly and efficiently.
