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.
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.
Create a secret that contains your kubeconfig.
# Change --from-file according to kubeconfig location in your set up. kubectl create secret generic octant-kubeconfig --from-file=/etc/kubernetes/admin.conf -n kube-system
You may need to update build/yamls/antrea-octant.yml according to your kubeconfig file name.
You can change the sample yaml 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
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 3. If the image is not successfully
downloaded which may be due to network issues, you can run command
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. In Antrea v0.8.2, the Traceflow UI is a separate Octant plugin called antrea-traceflow-plugin,
but it has been merged into antrea-octant-plugin on the master branch since then.
To get the latest version of Traceflow UI, please build image
antrea/octant-antrea-ubuntu via command
make octant-antrea-ubuntu and use the image antrea/octant-antrea-ubuntu:latest
for deploying UI as a Pod.
3. 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.
4. To deploy a released version of the plugin, you can download
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
Refer to Octant README for detailed installation instructions.
You can follow the steps listed below to install octant and antrea-octant-plugin on linux.
Get and install Octant v0.13.1.
Depending on your linux operating system, to install Octant v0.13.1, you can use either
dpkg -i octant_0.13.1_Linux-64bit.deb
rpm -i octant_0.13.1_Linux-64bit.rpm
Export your kubeconfig path (file location depends on your setup) to environment variable $KUBECONFIG.
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/vmware-tanzu/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/
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 OCTANT_LISTENER_ADDR=0.0.0.0:80 OCTANT_ACCEPTED_HOSTS=0.0.0.0 OCTANT_DISABLE_OPEN_BROWSER=true nohup octant &
Now, you are supposed to see Octant is running together with antrea-octant-plugin via URL http://(IP or $HOSTNAME):80.
Note: 1. If you deploy Octant and the Antrea UI as a process, you cannot access the Traceflow UI for now when following the steps listed above (at least until the v0.9.0 release). However, you can still build the binary yourself with the command below, with the remaining steps being almost the same as the ones above.
```bash # You will find the compliled binary under folder antrea/plugins/octant/bin. cd plugins/octant make antrea-octant-plugin ```
