How do you make a CI CD pipeline with Docker?
CI/CD (continuous integration/continuous delivery) pipelines have been gaining in popularity as organizations strive to improve their software development processes. In a CI/CD pipeline, developers frequently commit code to a shared repository, such as Git, and the pipeline automatically builds and tests the code, then deploys it to a staging or production environment.
A CI/CD pipeline can be implemented using a variety of technologies, but one of the most popular options is Docker. Docker allows developers to package an application and all its dependencies into a single container, which can then be easily deployed to any environment.
In this article, we’ll show you how to set up a CI/CD pipeline for a Java application using Docker. We’ll use the Jenkins CI server, and we’ll use the Gitlab repository manager to store our code.
We’ll start by creating a Dockerfile for our application. A Dockerfile is a text file that contains a list of instructions for building a Docker image. Our Dockerfile will install the Java Development Kit (JDK) and the Tomcat server, and it will copy our application code to the Tomcat server.
FROM java:8-jdk
ADD src /src
RUN mkdir -p /usr/local/tomcat/webapps/
COPY target/spring-boot-example-0.0.1.war /usr/local/tomcat/webapps/
ENV CATALINA_BASE /usr/local/tomcat
ENV CATALINA_HOME /usr/local/tomcat
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64
EXPOSE 8080
Next, we’ll create a Jenkins job to build our Docker image. Jenkins is a popular CI server that can be used to build Docker images. We’ll create a Jenkins job that will execute a Docker build command every time the code in our Gitlab repository is updated.
We’ll also need to create a Gitlab repository for our code. Gitlab is a popular repository manager that can be used to store code for Docker images.
Once our Gitlab repository is created, we can add our code to it. In our example, we’ll create a repository called “spring-boot-example.” We’ll add a file called “Dockerfile” to the repository, and we’ll add the code for our Java application to the file.
Our Dockerfile will look like this:
FROM java:8-jdk
ADD src /src
RUN mkdir -p /usr/local/tomcat/webapps/
COPY target/spring-boot-example-0.0.1.war /usr/local/tomcat/webapps/
ENV CATALINA_BASE /usr/local/tomcat
ENV CATALINA_HOME /usr/local/tomcat
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64
EXPOSE 8080
Now, we can add the Jenkins job to our Gitlab repository. We’ll create a file called “Jenkinsfile” in our repository, and we’ll add the following code to it:
node(‘docker-slave’) {
git url: ‘https://gitlab.com/spring-boot-example/spring-boot-example.git’
dockerfile: ‘Dockerfile’
Does Docker have CI CD?
Docker has come a long way and is now being used by many companies for their Continuous Integration and Delivery needs. But does Docker have a built-in CI/CD solution?
The answer is yes and no. Docker does have a few different options when it comes to CI/CD, but they are not all built-in. For example, you can use Jenkins to build and test your Docker containers, but this is not a built-in feature.
There are also a few products that are specifically built for CI/CD with Docker. These include Travis CI, CircleCI, and GitLab. They all have different features, but they all allow you to build and test your Docker containers as part of your pipeline.
So, if you are looking for a built-in solution, Docker does not have one. But if you are willing to use a third-party product, there are plenty of options available.
How Docker works in CI CD?
Continuous Integration (CI) and Continuous Delivery (CD) are two of the most important concepts in software engineering. CI ensures that code changes are integrated with minimal disruption, while CD ensures that those changes are delivered to users in a timely manner.
Docker has become a popular tool in both CI and CD pipelines. In this article, we’ll take a look at how Docker works in both contexts.
In a CI pipeline, Docker is typically used to create isolated environments for testing code changes. This helps to ensure that those changes don’t break existing functionality.
In a CD pipeline, Docker is used to deploy code changes to production servers. This helps to ensure that changes are rolled out in a controlled manner, and that they don’t cause any disruption to users.

What is Docker pipeline?
What is Docker pipeline?
The Docker pipeline is a process that helps organizations manage and deploy applications using Docker containers. The pipeline helps automate the process of building, testing, and deploying applications.
The Docker pipeline has three main components:
1. The build stage: This stage builds the application using Docker images.
2. The test stage: This stage tests the application for errors.
3. The deploy stage: This stage deploys the application to a production environment.
The Docker pipeline can be customized to meet the needs of your organization. For example, you can add or remove stages, or modify the stages to include additional steps.
What is the difference between Docker and Jenkins?
Docker and Jenkins are two of the most popular DevOps tools in use today. They both have a lot of features and benefits, but they are also quite different. In this article, we will explore the differences between Docker and Jenkins.
Docker is a containerization platform that allows you to package your applications and all of their dependencies into a single container. This makes it easy to deploy and manage your applications, and also makes them more portable.
Jenkins is a popular continuous integration (CI) tool. It allows you to automate the process of building and testing your applications. Jenkins can be used with Docker to help automate the process of building and testing your applications.
The main difference between Docker and Jenkins is that Docker is focused on containerization, while Jenkins is focused on CI. Jenkins can be used with Docker to help automate the process of building and testing your applications, but it is not limited to just that.
Both Docker and Jenkins are popular and powerful tools, and both have a lot to offer. If you are looking for a containerization platform, then Docker is a good option. If you are looking for a CI tool, then Jenkins is a good option.
What is CI CD using Jenkins?
CI CD using Jenkins is a process of software development and delivery that enables organizations to rapidly release software changes. The process helps ensure that software changes are safe to release, and that they meet the organization’s quality standards.
Jenkins is a popular open source tool that helps organizations automate the CI CD process. It enables you to easily integrate with popular source control systems,such as Git and SVN, and it provides a wide variety of plugins that help you automate common tasks,such as building, testing, and deploying software.
The CI CD process typically involves the following steps:
1. Develop software in a source code repository.
2. Automate the build process to compile and test the software.
3. Deploy the software to a test environment for further testing.
4. Deploy the software to a production environment.
The CI CD process can help organizations speed up the software development and delivery process, and it can help ensure that software changes are safe to release.
Is Kubernetes a CI CD tool?
Is Kubernetes a CI CD tool?
Kubernetes is an open source container orchestration system that helps you manage containerized applications throughout their lifecycle. It can be used as a CI CD tool, but it’s not limited to that use case.
Kubernetes can be used for CI because it can provision new containers for your application and test it automatically. You can also use it for CD because it can deploy your application to production.
However, Kubernetes is not limited to CI or CD. You can also use it for managing your application’s infrastructure, networking, and storage.
