Ci Cd Pipeline Docker
What is ci cd pipeline docker?
CI/CD pipelines help you automate the process of building, testing, and deploying software. By using containers, you can create a ci cd pipeline that is portable and easy to manage.
Docker is a popular containerization platform that you can use to create your ci cd pipeline. With Docker, you can create a self-contained environment for your applications. This makes it easy to deploy and test your applications.
In this article, we will show you how to create a ci cd pipeline using Docker and Jenkins. We will also show you how to deploy your applications using Docker.
Setting up the environment
The first step is to set up the environment. We will use a Docker container to run Jenkins.
You can install Jenkins on Ubuntu 18.04 by running the following command:
sudo apt-get install Jenkins
We will also need to install the Jenkins Docker plugin. You can install the plugin by running the following command:
sudo docker plugin install jenkins-ci-cd
The Jenkins Docker plugin allows you to run Jenkins in a Docker container.
Creating the Jenkins pipeline
Next, we will create a Jenkins pipeline. We will use the Jenkinsfile to define the pipeline.
The Jenkinsfile contains the following code:
pipeline {
agent any
stages {
stage(‘build’) {
steps {
echo ‘Building the application’
docker build -t myapp .
}
}
stage(‘test’) {
steps {
echo ‘Testing the application’
docker run -it myapp /bin/bash
}
}
stage(‘deploy’) {
steps {
echo ‘Deploying the application’
docker push myapp
}
}
}
The Jenkinsfile defines three stages: build, test, and deploy. The build stage will build the application using the docker build command. The test stage will test the application using the docker run command. The deploy stage will deploy the application using the docker push command.
You can run the Jenkins pipeline by running the following command:
sudo Jenkins -p mypipeline
The Jenkins pipeline will run in a Docker container.
Testing the pipeline
You can test the Jenkins pipeline by running the following command:
sudo Jenkins -p mypipeline -u username -p password
This will run the Jenkins pipeline using the username and password provided.
Deploying the application
You can deploy the application by running the following command:
sudo Jenkins -p mypipeline -d myapp
This will deploy the application to the Docker daemon.

Is Docker used for CI CD?
CI (continuous integration) and CD (continuous delivery) are two essential aspects of software development that help teams ship high-quality products faster. So, it’s no surprise that Docker is often used in CI/CD pipelines.
Docker can help with CI/CD in a few ways. First, it can speed up the build process by isolating the build environment. Second, it can help automate the deployment process. And third, it can make it easier to replicate the build and deployment environment.
All of this means that teams can move faster and more confidently towards releasing high-quality products.
How do you use Docker in CI CD pipeline?
With the rise in popularity of containers, Docker has become a popular tool for software development and deployment. But what is Docker, and how can you use it in your CI/CD pipeline?
Docker is a software container platform that enables you to build, ship, and run applications anywhere. Docker containers are lightweight and portable, and can be used to isolate applications and dependencies. This makes them an ideal tool for use in a CI/CD pipeline.
In a CI/CD pipeline, Docker can be used to speed up and simplify the build and deployment process. By using Docker, you can create a reproducible build environment that can be used for both development and production. You can also use Docker to create a self-contained environment for your applications and dependencies. This can help to ensure that your applications are always up-to-date and that your pipeline is reliable and consistent.
If you are new to Docker, or if you would like to learn more about how to use it in a CI/CD pipeline, there are a number of resources available online. The Docker website has a number of tutorials and guides that can help you get started. The Docker documentation is also a great resource for learning about all of the features of Docker.
If you are already familiar with Docker, and you would like to start using it in your CI/CD pipeline, there are a number of tools and services that can help you. The Travis CI blog has a great article on using Docker in your CI/CD pipeline. The article discusses a number of different tools and services that can help you get started.
Docker is a powerful tool, and can be used in a variety of ways in a CI/CD pipeline. If you are new to Docker, or if you would like to learn more about how to use it in your pipeline, the Docker website and documentation are a great place to start.
How do you build a Docker pipeline?
There are many ways to build a Docker pipeline. In this article, we will discuss one way to do it.
The first step is to create a file called “Dockerfile” in the root of your project. The Dockerfile contains all of the instructions that Docker will use to build your image.
Next, you will need to create a repository on Docker Hub or some other registry. This repository will store your image.
The next step is to create a script that will build your image. The script will use the Dockerfile to build your image.
The final step is to add the script to your project. The script will run every time you push your code to the repository. It will build your image and push it to the registry.
How do you create a CI CD pipeline in Jenkins Docker?
CI/CD pipelines help automate the process of software delivery, allowing teams to move their code from development to production more efficiently. Jenkins is a popular open-source tool for creating CI/CD pipelines, and Docker is a popular containerization platform. In this article, we’ll show you how to create a CI/CD pipeline for a Java application using Jenkins and Docker.
First, we’ll install Jenkins and Docker on a Linux server. We’ll then create a Jenkins job that builds a Docker image for our Java application. We’ll then configure the job to run in a Docker container, and we’ll create a pipeline that automates the testing and deployment of our application.
Installing Jenkins and Docker
To install Jenkins and Docker on a Linux server, we’ll need to run the following commands:
sudo apt-get update
sudo apt-get install Jenkins docker.io
After installing Jenkins and Docker, we’ll need to start the Jenkins service and the Docker service. We can do this by running the following commands:
sudo service Jenkins start
sudo service docker start
Creating a Jenkins Job
Next, we’ll create a Jenkins job that builds a Docker image for our Java application. We’ll do this by running the following command:
sudo Jenkins create job
In this command, is the name of the Jenkins job. We can give the job any name we want.
We’ll then need to add a build step to the job. We can do this by running the following command:
sudo Jenkins add build step
In this command, we’ll need to specify the type of build step we want to add. We’ll want to add a build step that builds a Docker image, so we’ll run the following command:
sudo Jenkins add build step docker build
We’ll then need to specify the path to our Java application, the name of our Docker image, and the tag for our Docker image. We can do this by running the following command:
sudo Jenkins add build step docker build –tag
In this command, is the tag for our Docker image.
We’ll then need to add a post-build action to the job. We can do this by running the following command:
sudo Jenkins add post build action
In this command, we’ll want to specify the type of post-build action we want to add. We’ll want to add a post-build action that launches a Docker container, so we’ll run the following command:
sudo Jenkins add post build action docker run
We’ll then need to specify the name of our Docker image and the tag for our Docker image. We can do this by running the following command:
sudo Jenkins add post build action docker run –image
–tag
In this command,
is the name of our Docker image and is the tag for our Docker image.
We’ll then need to add a post-build action to the job. We can do this by running the following command:
sudo Jenkins add post build action
In this command, we’ll want to specify the type of post-build action we want to add. We’ll want to add a post-build action that deploys our application, so we’ll run the following command:
sudo Jenkins add post build action docker deploy
We’ll then need to specify the name of our Docker image and the tag for our Docker image. We can do this by running the following command

What is Docker in pipeline?
Docker is a software container platform that enables developers to package their applications with all of the necessary dependencies into a standardized unit for software development. Containers allow for an isolated, clean environment for applications to run in, which helps to prevent dependency conflicts.
Pipeline is a software development platform that enables developers to build, test, and deploy their applications in a fast, consistent, and reliable manner. Pipeline makes use of Docker containers to streamline the software development process.
When used in conjunction, Docker and Pipeline provide a powerful and efficient platform for developing and deploying applications. Docker containers provide a clean and isolated environment for applications to run in, while Pipeline automates the process of building, testing, and deploying applications. This combination allows for a fast, consistent, and reliable software development and deployment process.
Is Kubernetes a CI CD tool?
CI/CD (continuous integration/continuous delivery) is a software development practice that helps automate the process of software delivery and deployment. Kubernetes is a container orchestration platform that can be used to manage and deploy containers in a clustered environment.
So, is Kubernetes a CI/CD tool? The answer is both yes and no. Kubernetes can be used to manage and deploy containers, which is a key part of the CI/CD process. However, Kubernetes is not specifically designed for CI/CD, and there are other tools that are better suited for this purpose.
That said, Kubernetes can be a valuable part of a CI/CD workflow. It can be used to manage and deploy containers in a clustered environment, which can help speed up the process of software delivery and deployment.
What is the difference between Docker and Jenkins?
Docker and Jenkins are both extremely popular tools in the DevOps world, but what is the difference between them?
Docker is a containerization platform that allows you to package your application and its dependencies into a standardized unit for software development. Jenkins is a continuous integration and delivery tool that allows you to automate the build, testing, and deployment of your applications.
Docker is more focused on the containerization of applications, while Jenkins is more focused on the automation of the build, testing, and deployment process. Jenkins can be used with Docker, but Docker is not required in order to use Jenkins.
In general, Docker is more popular for smaller applications, while Jenkins is more popular for larger applications. Jenkins has a much larger user base and a more comprehensive feature set, while Docker is more popular with the Docker community.
