Octant and antrea-octant-plugin installation


There are two ways to deploy Octant and antrea-octant-plugin.

  • Deploy Octant and antrea-octant-plugin as a Pod.

  • Deploy Octant and antrea-octant-plugin as a process.


antrea-octant-plugin depends on the Antrea monitoring CRDs (AntreaControllerInfo and AntreaAgentInfo) and Traceflow CRD (Traceflow).

To run Octant together with antrea-octant-plugin, please make sure you have these CRDs defined in you K8s cluster.

If Antrea is deployed before antrea-octant-plugin starts by using the standard deployment yaml, these CRDs should already be added. If not, please refer to antrea.yaml to create these CRDs first.

Deploy Octant and antrea-octant-plugin as a Pod

You can follow the sample below to run Octant and antrea-octant-plugin in Pod. In this example, we expose UI as a NodePort Service for accessing externally. You can update antrea-octant.yaml according to your environment and preference.

  1. Create a secret that contains your kubeconfig.

    # Change path to kubeconfig file according to your set up.
    kubectl create secret generic octant-kubeconfig --from-file=admin.conf=<path to kubeconfig file> -n kube-system
  2. You can change the sample yaml build/yamls/antrea-octant.yml according to your requirements and environment, then apply the yaml to create both Deployment and NodePort Service.

    kubectl apply -f build/yamls/antrea-octant.yml
  3. You can get the NodePort of antrea-octant Service via kubectl.

    # See field NodePort
    kubectl describe service antrea-octant -n kube-system

Now, you are supposed to see Octant is running together with antrea-octant-plugin via URL http://(IP or $HOSTNAME):NodePort.


  1. Docker image antrea/octant-antrea-ubuntu should be automatically downloaded when you apply antrea-octant.yml in step 2. If the image is not successfully downloaded which may be due to network issues, you can run command make octant-antrea-ubuntu to build the image locally. If it is the case, you need to make sure that the image exists on all the K8s Nodes since the antrea-octant Pod may run on any of them.
  2. If the Pod is running without any explicit issue but you can not access the URL, please take a further look at the network configurations in your environment. It may be due to the network policies or other security rules configured on your hosts.
  3. To deploy a released version of the plugin, you can download https://github.com/antrea-io/antrea/releases/download/<TAG>/antrea-octant.yml, where <TAG> (e.g. v0.3.0) is the desired version (should match the version of Antrea you are using). After making the necessary edits, you can apply the yaml with kubectl.

Deploy Octant and antrea-octant-plugin as a process

Refer to Octant README for detailed installation instructions.

You can follow the steps listed below to install octant and antrea-octant-plugin on linux.

  1. Get and install Octant v0.24.0.

    Depending on your linux operating system, to install Octant v0.24.0, you can use either

    wget https://github.com/vmware-tanzu/octant/releases/download/v0.24.0/octant_0.24.0_Linux-64bit.deb
    dpkg -i octant_0.24.0_Linux-64bit.deb


    wget https://github.com/vmware-tanzu/octant/releases/download/v0.24.0/octant_0.24.0_Linux-64bit.rpm
    rpm -i octant_0.24.0_Linux-64bit.rpm
  2. Export your kubeconfig path (file location depends on your setup) to environment variable $KUBECONFIG, otherwise ~/.kube/config will be used.

    export KUBECONFIG=/etc/kubernetes/admin.conf
  3. Get corresponding antrea-octant-plugin binary from Release Assets based on your environment and move the binary to OCTANT_PLUGIN_PATH.

    For example, you can get antrea-octant-plugin-linux-x86_64 if it matches your operating system and architecture.

    wget -O antrea-octant-plugin https://github.com/antrea-io/antrea/releases/download/<TAG>/antrea-octant-plugin-linux-x86_64
    # Make sure antrea-octant-plugin is executable, otherwise Octant cannot find it.
    chmod a+x antrea-octant-plugin
    # If you did not change OCTANT_PLUGIN_PATH, the default folder should be $HOME/.config/octant/plugins.
    mv antrea-octant-plugin $HOME/.config/octant/plugins/
  4. Start Octant as a background process with UI related environment variables.

    # Change port 80 according to your environment and set OCTANT_ACCEPTED_HOSTS based on your requirements

Now, you are supposed to see Octant is running together with antrea-octant-plugin via URL http://(IP or $HOSTNAME):80.


  1. You can also build the plugin binary yourself with the command below, with the remaining steps being almost the same as the ones above.

    # You will find the compliled binary under folder antrea/plugins/octant/bin.
    cd plugins/octant
    make antrea-octant-plugin
