Logging View Plugin for OpenShift Console

This plugin adds the logging view into the 'observe' menu in the OpenShift console. It requires OpenShift 4.10.

This plugin connects to a loki backend, you can install the loki-operator in your cluster.

Development

Node.js and npm are required to build and run the plugin. To run OpenShift console in a container, either Docker or podman 3.2.0+ and oc are required.

Running locally

Make sure you have loki running on http://localhost:3100

In one terminal window, run:

  1. npm install
  2. npm run dev

In another terminal window, run:

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

This will create an environment file scripts/env.list and 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.

The dynamic console plugin is configured to connect to loki using a proxy /api/proxy/plugin/logging-view-plugin/backend/, in local mode this will point to http://localhost:3100. You can disable this by re-running the console with npm run start:console -c to use the cluster proxy

Navigate to http://localhost:9000/monitoring/logs to see the running plugin.

Running start:console with Apple silicon and podman

If you are using podman on a Mac with Apple silicon, npm 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

Runing tests

Unit tests

npm run test:unit

e2e tests

In order to run the e2e tests, you need first to build the plugin in standalone mode

npm run build:standalone:instrumented

and then run the cypress tests

npm run test:e2e

Deployment on cluster

You can deploy the plugin to a cluster by instantiating the provided Plugin Resources. It will use the latest plugin docker image and run a light-weight nginx HTTP server to serve the plugin's assets.

oc create -f logging-view-plugin-resources.yml

Once deployed, patch the Console operator config to enable the plugin.

oc patch consoles.operator.openshift.io cluster \
  --patch '{ "spec": { "plugins": ["logging-view-plugin"] } }' --type=merge

Build the image

./scripts/image.sh -t latest
