Hawtio Online OpenShift Console Plugin

A dynamic plugin that integrates the Hawtio Online console into the OpenShift console.

Development

The plugin can be tested using a local development environment.

Option 1: Local

In one terminal window, run:

1. yarn install
2. yarn run start

In another terminal window, run:

1. oc login (requires oc and an OpenShift cluster)
2. yarn run start-console (requires Docker or podman 3.2.0+)

This will run the OpenShift console in a container connected to the cluster you've logged into. The plugin HTTP server runs on port 9001 with CORS enabled. Navigate to http://localhost:9000/example to see the running plugin.

Running start-console with Apple silicon and podman

If you are using podman on a Mac with Apple silicon, yarn run start-console might fail since it runs an amd64 image. You can workaround the problem with qemu-user-static by running these commands:

podman machine ssh
sudo -i
rpm-ostree install qemu-user-static
systemctl reboot

Option 2: Docker + VSCode Remote Container

Make sure the Remote Containers extension is installed. This method uses Docker Compose where one container is the OpenShift console and the second container is the plugin. It requires that you have access to an existing OpenShift cluster. After the initial build, the cached containers will help you start developing in seconds.

1. Create a dev.env file inside the .devcontainer folder with the correct values for your cluster:

OC_PLUGIN_NAME=hawtio-online-console-plugin
OC_URL=https://api.example.com:6443
OC_USER=kubeadmin
OC_PASS=<password>

2. (Ctrl+Shift+P) => Remote Containers: Open Folder in Container...
3. yarn run start
4. Navigate to http://localhost:9000/example

Docker image

Before you can deploy your plugin on a cluster, you must build an image and push it to an image registry.

1. Build the image:

   docker build -t quay.io/my-repository/my-plugin:latest .

2. Run the image:

   docker run -it --rm -d -p 9001:80 quay.io/my-repository/my-plugin:latest

3. Push the image:

   docker push quay.io/my-repository/my-plugin:latest

NOTE: If you have a Mac with Apple silicon, you will need to add the flag --platform=linux/amd64 when building the image to target the correct platform to run in-cluster.

Deployment on cluster

A Helm chart is available to deploy the plugin to an OpenShift environment.

The following Helm parameters are required:

plugin.image: The location of the image containing the plugin that was previously pushed

Additional parameters can be specified if desired. Consult the chart values file for the full set of supported parameters.

Installing the Helm Chart

Install the chart using the name of the plugin as the Helm release name into a new namespace or an existing namespace as specified by the plugin_hawtio-online-console-plugin parameter and providing the location of the image within the plugin.image parameter by using the following command:

helm upgrade -i  my-plugin charts/openshift-console-plugin -n plugin__hawtio-online-console-plugin --create-namespace --set plugin.image=my-plugin-image-location

NOTE: When deploying on OpenShift 4.10, it is recommended to add the parameter --set plugin.securityContext.enabled=false which will omit configurations related to Pod Security.

NOTE: When defining i18n namespace, adhere plugin__<name-of-the-plugin> format. The name of the plugin should be extracted from the consolePlugin declaration within the package.json file.
