Run in kubernetes as pod

Deploy with kubectl config

⚠️ Attention! ⚠️

This is an example to demonstrate how it works. Don’t do that in a production environment, don’t store your token in kubernetes secret!

Create secret kubeconfig with kubernetes config in default namespace

kubectl create secret generic kubeconfig --from-file=$HOME/.kube/config

Apply pod in default namespace

kubectl apply -f deploy/pod-kubeconfig.yaml

Deploy with serviceaccount and volume

⚠️ Attention! ⚠️

This is an example to demonstrate how it works. Do not do this in a production environment, the example below uses the cluster view role cluster-role-view.yaml, you have enough view permissions to dump the data.

Configure your role correctly according to your needs. You can find configuration examples in the /deploy directory.

Apply cluster admin sericeaccount, pvc, pod in kube-dump namespace:

kubectl create ns kube-dump
kubectl apply -n kube-dump -f deploy/cluster-role-view.yaml
kubectl apply -n kube-dump -f deploy/pvc.yaml
kubectl apply -n kube-dump -f deploy/pod-kubeconfig.yaml

Deploy with serviceaccount, ssh key and volume

Create an SSH key if you don’t have one or want to use a separate key

mkdir -p ./.ssh
chmod 0700 ./.ssh
ssh-keygen -t ed25519 -C "kube-dump" -f ./.ssh/kube-dump

You must add this key to your github / gitlab profile

cat ./.ssh/kube-dump.pub

Create namespace kube-dump and deploy secret, role, pvc and pod

kubectl create ns kube-dump
kubectl -n kube-dump create secret generic kube-dump-key \
  --from-file=./.ssh/kube-dump \
  --from-file=./.ssh/kube-dump.pub
kubectl apply -n kube-dump -f deploy/cluster-role-view.yaml
kubectl apply -n kube-dump -f deploy/pvc.yaml
kubectl apply -n kube-dump -f deploy/pod-sa-git-key.yaml

Execute your dump task

Execute dump in pod for all namespaces (if you can list namespaces)

kubectl exec -ti kube-dump -- /kube-dump ns

Or try dump self kube-dump namespace

kubectl exec -ti -n kube-dump kube-dump -- /kube-dump ns -n kube-dump
