Kubernetes cluster version >1.16 (minikube or kind are fine)
Verify with kubectl config current-context and kubectl version
One of the crossplane supported public cloud (AWS, Azure, Alibaba Cloud, GCK) access key and secret
Install Crossplane(later)
Download KubeVela release from release page
Unpack the package and add it to PATH by running sudo mv ./vela /usr/local/bin/vela
Run vela install

Lab 1: Use vela to deploy a simple application

Purpose: Showcase the simple to use, application centric vela user interfaces.

Sync with cluster vela system update
List installed workloads vela workloads
List installed traits vela traits

Deploy a simple application with

vela svc deploy back -t worker --image crccheck/hello-world --app lab1
vela svc deploy front -t webservice --image crccheck/hello-world --port 8000 --app lab1

Show application status vela app show lab1

Lab 2: Add and apply KubeWatch

Purpose: Showcase the steps to add and use capacity from community

Create a slack bot
Add a cap center vela cap center config mycap https://github.com/oam-dev/catalog/tree/master/registry
Check capabilities vela cap ls
Install the kubewatch capability vela cap add mycap/kubewatch
Create an application vela comp deploy mycomp -t webservice --image crccheck/hello-world --port 8000 --app lab2
Add kubewatch trait to the application vela kubewatch mycomp --app lab2 --webhook https://hooks.slack.com/<yourid>
Check the slack channel to verify the notifications

Lab 3: Manage cloud resource and applications in application centric way

Purpose: Showcase the application centric view of appfile

Install Crossplane (This lab uses crossplane version 0.13)

Also the examples are based on Alibaba Cloud settings

Create crossplane namespace: kubectl create ns crossplane-system
Install crossplane helm chart: helm install crossplane charts/crossplane/ --namespace crossplane-system
Install crossplane cli: curl -sL https://raw.githubusercontent.com/crossplane/crossplane/release-0.13/install.sh | sh
Add crossplane to PATH: sudo mv kubectl-crossplane /usr/local/bin
Configure cloud provider(Alibaba Cloud)
- Add cloud provider: kubectl crossplane install provider crossplane/provider-alibaba:v0.3.0
- Create provider secret: kubectl create secret generic alibaba-creds --from-literal=accessKeyId=<change here> --from-literal=accessKeySecret=<change here> -n crossplane-system
- Configure the provider: kubectl apply -f script/provider.yaml
Configure infrastructure: kubectl crossplane install configuration crossplane/getting-started-with-alibaba:v0.13

Import the database workload definition

First, register the db workload definition: kubectl apply -f script/def_db.yaml The webservice workload is customized a little. kubectl apply -f script/webservice.yaml Don't forget to update vela: vela system update

Apply the appfile

vela up

Access the web-ui

If you have a cluster supporting Ingress, the route trait will work. kubectl get ingress command will show the ip address of the web-ui. Copy that service and add the <ip address> kubevela.kubecon.demo record to your local machine's /etc/hosts. Then you may access the GUI from web browser.

If you don't have Ingress installed, the eaisest way to access the demo app is through port forwarding :kubectl port-forward <your webui pod name> 8080 and access it from browser using http://localhost:8080.
