How to Test Manually
$ minikube start- In the Vault folder,
$ make dev XC_ARCH=amd64 XC_OS=linux XC_OSARCH=linux/amd64
- Create a file called
vault-test.yaml with the following contents:
apiVersion: v1
kind: Pod
metadata:
name: vault
spec:
containers:
- name: nginx
image: nginx
command: [ "sh", "-c"]
args:
- while true; do
echo -en '\n';
printenv VAULT_K8S_POD_NAME VAULT_K8S_NAMESPACE;
sleep 10;
done;
env:
- name: VAULT_K8S_POD_NAME
valueFrom:
fieldRef:
fieldPath: metadata.name
- name: VAULT_K8S_NAMESPACE
valueFrom:
fieldRef:
fieldPath: metadata.namespace
restartPolicy: Never
- Create the pod:
$ kubectl apply -f vault-test.yaml
- View the full initial state of the pod:
$ kubectl get pod vault -o=yaml > initialstate.txt
- Drop the Vault binary into the pod:
$ kubectl cp bin/vault /vault:/
- Drop to the shell within the pod:
$ kubectl exec -it vault -- /bin/bash
- Install a text editor:
$ apt-get update, $ apt-get install nano
- Write a test Vault config to
vault.config like:
storage "inmem" {}
service_registration "kubernetes" {}
disable_mlock = true
ui = true
api_addr = "http://127.0.0.1:8200"
log_level = "debug"
- Run Vault:
$ ./vault server -config=vault.config -dev -dev-root-token-id=root
- If 403's are received, you may need to grant RBAC, example here: https://github.com/fabric8io/fabric8/issues/6840#issuecomment-307560275
- In a separate window outside the pod, view the resulting state of the pod:
$ kubectl get pod vault -o=yaml > currentstate.txt
- View the differences:
$ diff initialstate.txt currentstate.txt
