The following sections will be moved to https://docs.akash.network eventually.

Troubleshooting

To troubleshoot you'll need to know the following.

• We run an ingress-nginx pod on every Kubernetes worker node
• This ingress-nginx pod binds all of the ports listed above to 0.0.0.0 on every Kubernetes worker node
• The DNS A record config above should therefore include all Kubernetes worker nodes so that connections are balanced
• Similarly the firewall ports need to be opened to all Kubernetes worker nodes
• There are Kubernetes Ingress resources (kubectl get ingresses -A) that map the DNS CNAMES to backend services
• Therefore connections from outside can hit ANY Kubernetes worker node and ingress-nginx will proxy to the correct service
• Services (kubectl get services -A) are creates in the akash-services namespace pointing to the pods. These map the Ingress to the Pods.
• The pods in the akash-services namespace created by the Helm charts can run on any Kubernetes worker node and are found by the service by label

For troubleshooting the pods in the akash-services namespace you can tail the logs with kubectl logs -n akash-services <pod name>. For the Akash Node and Akash Provider Helm charts you can add --set debug=true which will add a long sleep to any failing containers. You can then exec into the pod using kubectl exec -ti -n akash-services <pod name> -- bash to debug.

Setting up Kubernetes on your laptop to test

You can try a lightweight Kubernetes k3s, it brings you a fully fledged Kubernetes in under 30 seconds! Quick hint on k3s to save your time: install k3s using curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="--disable=traefik" sh -s - command OR delete traefik LoadBalancer after k3s installation with kubectl -n kube-system delete svc traefik command so to not interfere with ingress-nginx-controller used for Akash deployments.

After installing k3s you will want configure the client:

mkdir ~/.kube
sudo cat /etc/rancher/k3s/k3s.yaml | tee ~/.kube/config >/dev/null

kubectl get nodes

Then, you need a funded wallet on the network that you would like to setup. In this documentation we'll use the mainnet which is the default in the chart. But you can override values to point to any other net.

Setting up Kubernetes on Bare Metal

We recommend using Kubespray or Rancher Kubernetes Engine when deploying to bare metal.
