Deploying Synergychat
You've been hired by SynergyChat! SynergyChat is a metaverse-enabled chat app that provides data-driven insights through cutting-edge AI models that run on Web 3 infrastructure. It's truly the pinnacle of Silicon Valley innovation and culture.
All that to say, it's like Discord but with extra features for businesses.
For the rest of this course, we'll be deploying SynergyChat web services to Kubernetes!
Deploying an Image
The kubectl create deployment command will create a "deployment" for us. We'll talk more about the nuances of "deployments" later. But to put it simply, we only need to provide two things:
- The name of the deployment (this can be anything, it's used to identify the deployment)
- The ID of the Docker image we want to deploy (it would be a full URL if we weren't hosting the image on Docker Hub, which is the default)
kubectl create deployment synergychat-web --image=docker.io/bootdotdev/synergychat-web:latest
This command will deploy a container built from this Docker image to your local k8s cluster.
Viewing Deployments
To make sure the deployment was successful, run:
kubectl get deployments
Accessing the Web Page
By default, resources inside of Kubernetes run on a private, isolated network. They're visible to other resources within the cluster, but not to the outside world.
In order to access the application from your local network, you'll need to use kubectl to do some port forwarding. First, run:
kubectl get pods
We'll talk more about pods later, but for now, a pod is an abstraction over a container, and remember, a container is just a running instance of an image. To oversimplify, a pod is a running application.
You should see something like this:
NAME READY STATUS RESTARTS AGE
synergychat-web-679cbcc6cd-cq6vx 1/1 Running 0 20m
Next, run:
kubectl port-forward PODNAME 8080:8080
Be sure to replace PODNAME with your pod's name. In my case, it was synergychat-web-679cbcc6cd-cq6vx.
Next, open your browser and navigate to http://localhost:8080. You should see a webpage titled "SynergyChat"! Keep in mind, that we haven't configured all the resources the page needs yet, so the forms won't work, but the page should load.
Run and submit the CLI tests.
