+# log-viewer microfrontend (WIP)
+This is an experimental microfrontend to view logs coming from camtiler, testing microfrontends concept and developing
+Javascript/Node application directly on Kubernetes cluster using Skaffold (hot-reloading source files works!)
+
+Currently the application itself is a really minimalistic frontend based on Vue.js 3 framework.
+
+## Getting started
+0. Have access with kubectl to desired Kubernetes cluster 
+0. Have local Docker daemon ready along with access to your image registry (building in-cluster with Kaniko is currently not tested) 
+1. Get Skaffold 2.0.0-beta*: https://github.com/GoogleContainerTools/skaffold/releases
+2. Run `skaffold dev --namespace {desired K8S namespace}`
+
+And you should be good to go. Skaffold would create a deployment, build the container and upload it to your registry
+and deploy it.
+
+## Good to know
+### Skaffold
+All Skaffold configuration is in skaffold.yml. There we have:
+1. App/deployment name (metadata)
+2. Build artifacts - artifact that Skaffold would build and use, either in case of development or also actual deploy
+3. Profiles - similar to `npm` commands/profiles, you can have many different actions (run `skaffold {action}`).
+   We only have `dev` which will build and deploy the `log-viewer-frontend` container
+   (in manner how it's defined in Kubernetes manifest), and then enable `manual sync`, which defines which 
+   changed files will be copied to the container when it's running - change in everything else will trigger
+   rebuilding the container.
+
+### Hot-reload vs rebuilding the container
+Currently the files that will be copied are fine-tuned as they are known to work well with Vue.js hot-reload feature
+(eg actual frontend code). Other files, such as framework configuration files (`vite.config.js`, `vue.config.js`)
+will trigger rebuilding and more importantly, restarting the container, to provide stability. It might not be necessary
+to restart the container, this is just testing at this point. You can try it by introducing less explicit `sync` 
+config in `skaffold.yml`.
+
+Change in `packages*` files will also trigger rebuilding and restarting the container, with the difference of
+caching the result of the `npm install` command - `node_modules` directory. So in case of changing framework config,
+the container will be quickly rebuilt and restarted, but when changing packages in `package.json`, `npm install`
+will also be ran when re-building the container.
+
+### Dockerfile
+This is a really simple Dockerfile based on the official Node Docker image.
+Only extra stuff it does is:
+1. exposing the port for reference
+2. changing workdir(?)
+3. running `npm install` on-demand
+4. copying other code into the container
+5. defining the run command (important!)
+
+We also have the `.dockerignore` to filter out files that never need to make into the container, such as IDE
+metadata directories, Git, readme etc.
+
+With the current config, your local Docker daemon will be used to build the image and upload it to your image registry.
+Building in-cluster with Kaniko should be supported (https://skaffold.dev/docs/pipeline-stages/builders/docker/)
+but currently not tested. 
+
+### Kubernetes
+The Kubernetes manifest(s) are supposed to be in the `k8s/` directory.
+Skaffold will pick them up automatically from there, apply them (also cleaning up after itself),
+and match the container images from it's manifest and Kubernetes manifest, so it knows when to make the Kubernetes
+redeploy the image.
+
+Here we have a simple deployment, where `https://playground.k-space.ee/` takes us to the (development) frontend
+container and `https://playground.k-space.ee/events` gets data from the `camtiler log-backend`.
+
+The actual production usage may vary a lot in case of frontend - one would usually not run a 
+Node.js server to serve frontend assets, unless it's a SSR frontend (Nuxt, Next frameworks).
+But for Node.js backends, it's pretty close to the standard.
