How to Automate Database Deployment with Liquibase and Jenkins

Are you tired of manually deploying databases to multiple environments? Do you want a solution that will help you automate this process and make it more efficient? Well, you're in luck! In this article, we will explore how to use Liquibase and Jenkins to automate database deployment.

What is Liquibase?

Liquibase is an open-source tool that allows you to manage database changes and deployments. It tracks database changes in version control and applies them to multiple environments, making it easy to keep development, testing, and production environments in sync.

Liquibase uses a declarative approach to database changes, which means that you specify what you want to change instead of writing SQL code. This makes it easier to manage and track changes, and ensures consistent deployments across environments.

What is Jenkins?

Jenkins is a popular open-source tool for continuous integration and continuous deployment (CI/CD). It helps automate the build, test, and deployment processes, making it easier to deliver software changes quickly and reliably.

Jenkins can be integrated with various tools and plugins, which makes it highly customizable and versatile. In this article, we will use Jenkins to automate database deployments using Liquibase.

Setting Up Liquibase and Jenkins

Before we can start automating database deployments, we need to set up Liquibase and Jenkins.

Installing Liquibase

To install Liquibase, you can download the latest version from the Liquibase website. Liquibase requires Java to run, so make sure you have Java installed on your machine.

Once you have downloaded Liquibase, extract the files and add the Liquibase executable to your PATH. You can do this by adding the following line to your .bash_profile file (or equivalent for your operating system):

export PATH=$PATH:/path/to/liquibase/bin

You can test that Liquibase is installed correctly by running the following command in your terminal:

liquibase --version

This should display the version of Liquibase that you have installed.

Installing Jenkins

To install Jenkins, you can download the latest version from the Jenkins website. Jenkins requires Java to run, so make sure you have Java installed on your machine.

Once you have downloaded Jenkins, extract the files and run the following command in your terminal to start the Jenkins server:

java -jar jenkins.war

This will start the Jenkins server on port 8080. You can access the Jenkins web interface by opening a web browser and navigating to http://localhost:8080.

Configuring Liquibase

Before we can start using Liquibase, we need to configure it to connect to our database. Liquibase supports various databases, so make sure you have the appropriate JDBC driver for your database installed.

To configure Liquibase, we need to create a file in the root of our project directory. This file should contain the following properties:

# Database connection properties

# Change log properties

Replace the url, username, and password values with your database connection details. The changeLogFile property specifies the path to the Liquibase change log file, which we will create in the next section.

Creating a Liquibase Change Log

A Liquibase change log is an XML file that contains a list of changesets. Each changeset describes a single change to the database schema or data.

To create a Liquibase change log, create a new file called changelog.xml in the root of your project directory. Add a changeset to the file, like so:

<?xml version="1.0" encoding="UTF-8"?>
<databaseChangeLog xmlns=""

    <changeSet id="1" author="me">
        <createTable tableName="users">
            <column name="id" type="int"/>
            <column name="name" type="varchar(255)"/>


This creates a table called users with two columns: id and name.

You can create additional changesets in the changelog.xml file to describe any additional changes to the database schema or data.

Configuring Jenkins

Now that we have Liquibase set up and a change log file created, we can move on to configuring Jenkins to automate database deployments.

To configure Jenkins, we need to install the Liquibase plugin. To do this, navigate to the Manage Jenkins > Manage Plugins page in the Jenkins web interface. Click on the Available tab and search for "Liquibase". Select the Liquibase plugin and click Install.

Once the plugin is installed, we need to create a new Jenkins job to automate our database deployments. To do this, navigate to the Jenkins home page and click on the New Item button. Give the job a name and select the Freestyle project option.

On the job configuration page, add a new Build step by clicking on the Add build step button and selecting the Liquibase option. Configure the Liquibase build step as follows:

You can leave the other options at their default values. Save your changes and click on the Build Now button to run the job.

If everything is set up correctly, Jenkins will run Liquibase and apply the changes in your change log file to the specified database.

Automating Database Deployments with Jenkins

Now that we have our Jenkins job set up to run Liquibase, we can automate database deployments by integrating the job with our CI/CD pipeline.

The exact details of how you integrate your Jenkins job with your pipeline will depend on your specific setup. However, here are some general steps to get you started:

By automating database deployments, you can streamline your development process and reduce the risk of errors and downtime.


Automating database deployments with Liquibase and Jenkins can save you time and reduce the risk of errors. By using a declarative approach to database changes and automating the deployment process, you can ensure consistent and reliable deployments across environments.

In this article, we've explored how to set up Liquibase and Jenkins, configure them to work together, and automate database deployments. By following these steps, you can improve your database operations management and streamline your CI/CD pipeline.
