Knative
Kubernetes 上に構築できる、サーバーレスの基盤。
code:install.sh
# /var/snap/microk8s/common/addons/community/addons/knative/enable を編集
Enable metalb addon to get a loadbalancer for Knative Serving, for example microk8s enable metallb:xx.xx.xx.xx-yy.yy.yy.yy
Configure the domain for Knative services using:
kubectl get svc -n knative-serving kourier
kubectl patch configmap -n knative-serving config-domain -p '{data: {EXTERNAL-IP.sslip.io: }}'
To be able to use 'microk8s kn <plugin>' such as 'func' add to env PATH the value /var/snap/microk8s/common/plugins

type: LoadBalancer だが、これを type: Ingress に変更する
...と思ったけど、LoadBalancer のままでも Ingress と接続できるから問題ないかも
