How to download IBM Liberty?
You can download IBM Liberty in different ways depending on your needs and preferences. Here are some of the options:
Download as a ZIP file
You can download IBM Liberty as a ZIP file from the IBM Liberty website. You can choose from different editions and versions of IBM Liberty. For example, you can download the full platform edition that includes all the features of IBM Liberty or the base edition that includes only the core features. You can also download the latest release or a specific release of IBM Liberty. After downloading the ZIP file, you can extract it to any location on your file system.
Download as a Maven or Gradle dependency
You can download IBM Liberty as a Maven or Gradle dependency from the Maven Central repository. You can specify the group ID as io.openliberty, the artifact ID as openliberty-runtime, and the version as the desired release of IBM Liberty. For example,
<dependency> <groupId>io.openliberty</groupId> <artifactId>openliberty-runtime</artifactId> <version>184.108.40.206</version> <type>zip</type> </dependency>
This will download IBM Liberty as a ZIP file to your local Maven or Gradle repository. You can then unzip it to any location on your file system.
Download as a container image
You can download IBM Liberty as a container image from the Docker Hub repository. You can choose from different tags that correspond to different editions and versions of IBM Liberty. For example,
docker pull openliberty/open-liberty:full-java11-openj9-ubi
This will download the full platform edition of IBM Liberty with Java 11 OpenJ9 on Red Hat Universal Base Image (UBI). You can then run IBM Liberty as a container using Docker or any other container platform.
How to install and run IBM Liberty?
You can install and run IBM Liberty in different ways depending on how you downloaded it. Here are some of the options:
Install from a ZIP file
If you downloaded IBM Liberty as a ZIP file, you can install it by extracting it to any location on your file system. For example,
unzip openliberty-220.127.116.11.zip -d /opt/ibm
This will create a directory called wlp under /opt/ibm, which is the installation directory of IBM Liberty. You can then run IBM Liberty by using the server command under the wlp/bin directory. For example,
/opt/ibm/wlp/bin/server start defaultServer
This will start the default server instance of IBM Liberty, which is configured by the server.xml file under the wlp/usr/servers/defaultServer directory. You can then access your application by using the URL http://localhost:9080.
Install from a Maven or Gradle dependency
If you downloaded IBM Liberty as a Maven or Gradle dependency, you can install it by using the liberty-maven-plugin or the liberty-gradle-plugin. These plugins allow you to create, configure, and manage IBM Liberty servers and applications. For example, you can use the following Maven command to create a server instance and install an application:
mvn liberty:run-server -DserverName=myServer -DappArchive=myApp.war
This will create a server instance called myServer under the target/liberty/wlp/usr/servers directory, install the application myApp.war to the server, and run the server. You can then access your application by using the URL http://localhost:9080/myApp.
Install from a container image
If you downloaded IBM Liberty as a container image, you can install it by using Docker or any other container platform. You can use the Dockerfile or the docker-compose.yml file to define how to build and run your container. For example, you can use the following Dockerfile to create a container image that includes IBM Liberty and your application:
# Use the full platform edition of IBM Liberty with Java 11 OpenJ9 on UBI as the base image FROM openliberty/open-liberty:full-java11-openj9-ubi # Copy your application to the dropins directory COPY myApp.war /config/dropins/ # Expose port 9080 for HTTP access EXPOSE 9080
You can then build and run your container image by using the following Docker commands:
# Build your container image with the tag my-image docker build -t my-image . # Run your container image with the name my-container docker run -d --name my-container -p 9080:9080 my-image
This will run your container image as a detached process, map port 9080 of the container to port 9080 of the host, and name your container as my-container. You can then access your application by using the URL http://localhost:9080/myApp.
Run IBM Liberty in dev mode
If you want to develop your application with IBM Liberty, you can use dev mode to automatically detect changes in your code and deploy them to your running server. Dev mode also provides useful features such as hot testing, debugging, and code completion. You can use dev mode by using the liberty-maven-plugin or the liberty-gradle-plugin. For example, you can use the following Maven command to start dev mode:
This will start a server instance with your application and monitor your source files for changes. Whenever you save a file, dev mode will recompile and redeploy your application. You can also run tests, debug your code, or interact with dev mode using commands.
