Extremely terse instructions for setting up Workadventure on Kubernetes

Deploy workadventure with Kubernetes

Some slight adaptation of deeployer.libsonnet is necessary. My diff looks like this:

diff --git a/deeployer.libsonnet b/deeployer.libsonnet

Then, the following defines all the necessary resources to run it on a Digital Ocean Kubernetes cluster:

alias deeployer-k8s='docker run --rm -it -e "JSON_ENV=$(jq -n env)" -v $(pwd):/var/app thecodingmachine/deeployer:latest deeployer-k8s'
export ADMIN_API_TOKEN=veri_secret_api_token
export JITSI_ISS=
export JITSI_URL=meet.jit.si
export SECRET_JITSI_KEY=
kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v1.1.0/cert-manager.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.43.0/deploy/static/provider/do/deploy.yaml
deeployer-k8s show | kubectl apply -f -

Theoretically everything should be running by then. For me what still failed was DNS. Also the cert-manager loopback check was failing. So, there were two more steps in practice:

• Configure DNS to Load balancer IP for ingress
• Unfuck cert-manager loopback check by using quay.io/cfra/cert-manager-controller:v1.1.0
