Install OpenDaylight on Ubuntu 24.04 LTS (Quick and Easy!)

Infrastructure Architects at Internet Service Providers (ISP), Cloud Service Providers (CSP) and Academic Institutions use the OpenDaylight (ODL) platform to command, control, monitor and automate computer networks.

OpenDaylight Logo

These Infrastructure Architects use ODL for the following activities:

  • Service Delivery Automation
    • Program circuit provisioning and virtual private networks on-demand. Replace your Cisco certified technician with code.
  • Cloud and NFV
    • Follow the lead of Amazon Web Services (AWS) and launch your own Virtual Private Clouds (VPC), replete with path discovery and attack surface reduction.
  • Network Resources Optimization (NRO)
    • Prioritize and provision throughput based on load and state. Un-jam packet traffic.
  • Visibility and Control
    • Make correct Capital Expenditure (CAPEX) decisions thanks to bountiful usage information.

Based on Search query data, Infrastructure Architects prefer to install OpenDaylight on Ubuntu Linux.

Ubuntu 24.04 LTS "Noble Numbat" improves the Graphical User Interface (GUI), App Center Organization and choice of Security features. Ubuntu will also support Noble Numbat until 2036.

For Six Years I have provided the authoritative guide on HOWTO easily install OpenDaylight without a headache. I present the clearest and simplest method to install ODL.

To install OpenDaylight on Ubuntu LTS 24.04, simply:

  1. Prepare the Operating System (OS)
  2. Install the Java Development Kit (JDK)
  3. Set JAVA_HOME
  4. Download the OpenDaylight Zip
  5. Unzip OpenDaylight
  6. Start OpenDaylight
  7. Bonus: How do I install DLUX?

My field-tested approach reduces time-to-OpenDaylight.

For advanced use cases, please consider my other blog posts:

1. Prepare the Operating System (OS)

Use the apt package manager to patch the Ubuntu Operating System and update your applications.

apt-get update updates the package index with recent data.

$ sudo apt-get -y update

The upgrade flag commands Ubuntu to download and install packages.

$ sudo apt-get -y upgrade

We need unzip to extract software from the ODL archive.

$ sudo apt-get -y install unzip

2. Install the Java Development Kit (JDK)

OpenDaylight runs on the cross-platform Java Development Kit (JDK).

To comply with security best practices, use the most recent JDK.

NOTE: Oracle and the Java foundation stopped offering a Java Runtime Environment (JRE) at Java 11

Use apt-cache search to find the available versions of openjdk.

sudo apt-cache search openjdk

The command outputs an assortment of JAVA versions.

~$ sudo apt-cache search openjdk
default-jdk - Standard Java or Java compatible Development Kit
default-jre - Standard Java or Java compatible Runtime
openjdk-17-jdk - OpenJDK Development Kit (JDK)
openjdk-17-jre - OpenJDK Java runtime, using Hotspot JIT
openjdk-11-jdk - OpenJDK Development Kit (JDK)
openjdk-11-jre - OpenJDK Java runtime, using Hotspot JIT
openjdk-19-jdk - OpenJDK Development Kit (JDK)
openjdk-19-jre - OpenJDK Java runtime, using Hotspot JIT
openjdk-20-jdk - OpenJDK Development Kit (JDK)
openjdk-20-jre - OpenJDK Java runtime, using Hotspot JIT
openjdk-21-jdk - OpenJDK Development Kit (JDK)
openjdk-21-jre - OpenJDK Java runtime, using Hotspot JIT
openjdk-22-jdk - OpenJDK Development Kit (JDK)
openjdk-22-jre - OpenJDK Java runtime, using Hotspot JIT
openjdk-8-jdk - OpenJDK Development Kit (JDK)
openjdk-8-jre - OpenJDK Java runtime, using Hotspot JIT

Choose and install a version. I choose openjdk-22-jre.

The following command installs the JAVA 22 JDK.

$ sudo apt-get -y install openjdk-22-jre

Note: Even though we requested the JRE Ubuntu installs a JDK (The Java foundation discontinued the JRE - see note above)

To configure ODL, we need to record the full path to the JAVA JDK.

update-alternatives finds this path.

$  sudo update-alternatives --config java
There is 1 choice for the alternative java (providing /usr/bin/java).

  Selection    Path                                         Priority   Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-22-openjdk-amd64/bin/java   2211      auto mode
  1            /usr/lib/jvm/java-22-openjdk-amd64/bin/java   2211      manual mode

Press <enter> to keep the current choice[*], or type selection number:

Hit enter to keep the current choice.

NOTE: If you see more than one option for the java command, select JAVA 22

update-alternatives outputs the full path to your JAVA executable. You need this full path to set the JAVA_HOME environment variable. OpenDaylight requires this information. Copy the full path for the next section.

3. Set JAVA_HOME

Get the full path to your JAVA executable:

~$ ls -l /etc/alternatives/java
lrwxrwxrwx 1 root root 43 Sep 26  2023 /etc/alternatives/java -> /usr/lib/jvm/java-22-openjdk-amd64/bin/java

OpenDaylight requires that JAVA_HOME points to the parent JAVA directory and NOT the JAVA executable.

To accommodate, remove bin/java from the path.

On Ubuntu LTS 24.04, the JAVA 22 JDK resides in /usr/lib/jvm/java-22-openjdk-amd64

Edit your BASH resource file to persist the JAVA_HOME environment variable.

$ echo 'export JAVA_HOME=/usr/lib/jvm/java-22-openjdk-amd64' >> ~/.bashrc

Ubuntu will load your BASH resource file at each login.

If you want to load the JAVA_HOME environment variable, you can (1) exit your shell and log back in or (2) source your .bashrc:

$ source ~/.bashrc

Double check that $JAVA_HOME ends at /java-22-openjdk-amd64. It must not include /bin/java.

$ echo $JAVA_HOME
/usr/lib/jvm/java-22-openjdk-amd64

4. Download the OpenDaylight Zip Archive

To download the Zip archive, you can either (1) use OpenDaylight website, or (2) use my priceless download table.

WARNING: The ODL website includes curveballs (see below) that will aggravate you. I recommend you use my table to get the Zip.

Option 1: The John Sobanski Table Method

OpenDaylight hides the required, pre-compiled controller binaries.

To make life easy (for you), I located the binaries and recorded their URL in the following table.

NOTE: You're welcome!

Copy the link to your desired release. Right click the version, and select Copy link address.

Right Click my Table

Use a CURL command with capital O ("Oscar" - Not Zero) to yank the Zip from the copied link.

In the example below, I download the Potassium release.

$ curl -XGET -O https://nexus.opendaylight.org/content/repositories/opendaylight.release/org/opendaylight/integration/karaf/0.19.2/karaf-0.19.2.zip
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  252M  100  252M    0     0   138M      0  0:00:01  0:00:01 --:--:--  138M

NOTE: You want the Zip's name to begin with karaf and not opendaylight.

If you have the right Zip in hand, then skip the next section.

Option 2: Navigate the OpenDaylight Download page.

From the OpenDaylight project's home page and click Developer.

NOTE: If you completed the section above, then skip this option.

From the Hamburger Menu (Three Horizontal Bars), click Get Started.

Click Hamburger

Click Download.

Click the Download

Scroll down to the section that reads Archived Releases.

Archived Releases

Do not click on Fluorine and Newer, since that links to the source code.

If you hover over the link, you will not see karaf in the path. This lack of karaf in the path indicates source code.

Source Code Releases

BEWARE: Avoid the Fluorine and Newer link. You want precompiled binaries, and not source code.

Look for links in the Archived Releases section that include the word karaf. Paths that include karaf indicate precompiled binaries. You can find all releases in these folders, including Potassium and Argon.

Binary Releases

Click a link that leads to precompiled binaries.

Copy the link to your desired release. Right click the version, and select Copy link address.

Binary

Use a CURL command with capital O ("Oscar" - Not Zero) to yank the Zip from the copied link.

$ curl -XGET -O https://nexus.opendaylight.org/content/repositories/opendaylight.release/org/opendaylight/integration/karaf/0.12.2/karaf-0.12.2.zip
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  260M  100  260M    0     0  32.5M      0  0:00:07  0:00:07 --:--:-- 35.6M

5. Install OpenDaylight

Use the Ubuntu ls command to validate the CURL download.

NOTE: You may see a different version number.

$ ls
karaf-0.19.2.zip

NOTE: The Zip name must start with karaf and not opendaylight. If you do not see the word karaf in your Zip's name then return to Step 4

unzip the Zip archive.

$ unzip karaf-0.19.2.zip 

If you enter the un-zipped directory and list the contents, you should see a bin directory.

~$ :~$ cd karaf-0.19.2/
~/karaf-0.19.2$ ls

7. How do I install DLUX?

OpenDaylight stopped support of the OpenDaylight User Experience (DLUX) User Interface (UI) in 2019.

If you attempt to install DLUX on a post-Oxygen release, Karaf will bark: Error executing command: No matching features for odl-l2switch-switch-ui.

opendaylight-user@root>feature:install odl-l2switch-switch-ui
Error executing command: No matching features for odl-l2switch-switch-ui/0
opendaylight-user@root>

To use the DLUX UI, install Oxygen or earlier.

Oxygen, Helium, Lithium, Beryllium, Boron, Carbon and Nitrogen all support DLUX.

Install a version that supports DLUX

Press Control+D to stop your Karaf session.

Download a DLUX compliant version into your home dir.

~/karaf-0.19.2$ cd ~
~$ curl -O https://nexus.opendaylight.org/content/repositories/opendaylight.release/org/opendaylight/integration/karaf/0.8.4/karaf-0.8.4.zip

Unzip the Zip file.

~$ unzip karaf-0.8.4.zip 

Enter the new directory and start the service.

~$ cd karaf-0.8.4/
~/karaf-0.8.4$ ./bin/karaf 
Error occurred during initialization of boot layer
java.lang.module.FindException: Module java.xml.bind not found

You might see the error:

Error occurred during initialization of boot layer
java.lang.module.FindException: Module java.xml.bind not found

The Java foundation removed java.xml.bind from the JAVA JDK in 2018.

The Java 11 release (2018) reads:

java.xml.bind (JAXB) - REMOVED

  • Java 8 - OK
  • Java 9 - DEPRECATED
  • Java 10 - DEPRECATED
  • Java 11 - REMOVED

If you install JAVA 10 or earlier, you will fix the OpenDaylight issue java.lang.module.FindException: Module java.xml.bind not found.

JAVA 8, for example, fixes the issue.

$ sudo apt-get install openjdk-8-jre

Configure Ubuntu to use JAVA 8 instead of JAVA 22 with the update-alternatives command.

NOTE: Ubuntu accommodates multiple versions of JAVA without any problems

Select JAVA 8 from the menu. In the example below I choose option 2.

$ sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-22-openjdk-amd64/bin/java      2211      auto mode

  2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode


Press <enter> to keep the current choice[*], or type selection number: 2
update-alternatives: using /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java to provide /usr/bin/java (java) in manual mode

Verify that Ubuntu registered the older version:

$ java -version
openjdk version "1.8.0_402"
OpenJDK Runtime Environment (build 1.8.0_402-8u402-ga-2ubuntu1~23.10.1-b06)
OpenJDK 64-Bit Server VM (build 25.402-b06, mixed mode)

NOTE: If you see Error: Could not create the Java Virtual Machine. check that you did not use two dashes for -version

Update your **bashrc** file.

Find the path to the new (old) **JAVA 8**.

```bash
$ ls -l /etc/alternatives/java
lrwxrwxrwx 1 root root 46 Jul 30 14:31 /etc/alternatives/java -> /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

In JAVA_HOME, remove the bin/java suffix.

Turn the path:

/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

Into:

/usr/lib/jvm/java-8-openjdk-amd64/jre

vim the ~/.bashrc file.

~$: vim ~/.bashrc

Change:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64

To:

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre

...and source the file.

~$ source ~/.bashrc

echo your JAVA_HOME environment variable.

~$ echo $JAVA_HOME 
/usr/lib/jvm/java-8-openjdk-amd64/jre

Enter the directory that contains the new (old) DLUX compliant version of ODL.

$ cd ~/karaf-0.8.4/
