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
