+# Vault na Kubernetes
+
+Znajdziesz tutaj komendy do uruchomienia Vault. 
+
+## 1. Instalacja Vault z Helm Chart
+
+```shell
+CHARTDIR=/tmp/vault-helm
+
+git clone https://github.com/hashicorp/vault-helm $CHARTDIR
+
+DNSDOMAIN="$(minikube ip).nip.io"
+
+helm install vault -f vault-values.yaml \
+    --set server.ingress.hosts[0].host=vault.${DNSDOMAIN} \
+    $CHARTDIR
+
+echo http://vault.${DNSDOMAIN}
+
+
+cat << EOF
+##################
+
+# Komenda do zalogowania na poda z vaultem
+
+kubectl exec -ti vault-0 sh
+
+# Inicjalizacja
+
+vault operator init
+
+# NIE ZAPOMNIJ zapisać informacji które powyższa komenda zwróci! 
+
+# Użyj 3 tokenów do "odpieczętowania" vaulta komendą
+
+vault operator unseal
+
+# Eksport zmiennych na twoim kliencie
+
+export VAULT_ADDR=http://vault.${DNSDOMAIN}
+export VAULT_TOKEN=<ROOT_TOKEN_GENERATED_DURING_INIT>
+
+EOF
+```
+
+## 2. Konfiguracja Vaulta
+
+*Oparte głównie na wpisie z oficjalnego bloga https://www.hashicorp.com/blog/injecting-vault-secrets-into-kubernetes-pods-via-a-sidecar*
+
+
+```shell
+## Część Kubernetesowa - wykonaj z poda vaulta
+
+## Potrzebujesz też tokenu root:
+## export VAULT_TOKEN=<ROOT_TOKEN>
+
+cat <<EOF > /home/vault/app-policy.hcl
+path "secret*" {
+  capabilities = ["read"]
+}
+EOF
+
+vault policy write app /home/vault/app-policy.hcl
+
+vault auth enable kubernetes
+
+vault write auth/kubernetes/config \
+   token_reviewer_jwt="$(cat /var/run/secrets/kubernetes.io/serviceaccount/token)" \
+   kubernetes_host=https://${KUBERNETES_PORT_443_TCP_ADDR}:443 \
+   kubernetes_ca_cert=@/var/run/secrets/kubernetes.io/serviceaccount/ca.crt
+
+
+# allow access from all namespaces with 'app' sa only
+vault write auth/kubernetes/role/myapp \
+   bound_service_account_names=app \
+   bound_service_account_namespaces='*' \
+   policies=app \
+   ttl=1h
+
+# not enabled by default?
+vault secrets enable -path=secret kv
+
+# create secret
+
+vault kv put secret/helloworld username=hellovault password=P@ssw0rd123
+```
+
+## 3. Instalacja aplikacji
+
+```shell
+kubectl apply -f krazy-cow.yaml
+```
+
+Weryfikacja - nie powinno być żadnych danych w `/vault/secrets`:
+
+```shell
+kubectl iexec krazy-cow -- ls -l /vault/secrets
+```
+
+Dodanie anotacji agenta vaulta do aplikacji:
+
+```shell
+kubectl patch deployment krazy-cow --patch "$(cat krazy-cow-patch.yaml)"
+```
+
+Ponowna weryfikacja
+
+```shell
+kubectl iexec krazy-cow -- ls -l /vault/secrets
+kubectl iexec krazy-cow -- cat /vault/secrets/helloworld
+```
+
+Zmiana szablonu dla wynikowego pliku:
+
+```shell
+kubectl patch deployment krazy-cow --patch "$(cat krazy-cow-patch2.yaml)"
+```
+
+## 4. Vault i dynamiczne poświadczenia (credentials) do bazy danych
+
+Instalacja bazy
+
+```shell
+helm install mydb \
+  --set postgresqlPassword=secretpassword,postgresqlDatabase=mydatabase \
+  --set service.type=NodePort,service.nodePort=32543 \
+    stable/postgresql
+```
+
+Włączenie silnika obsługi baz danych na vault
+
+```shell
+vault secrets enable database
+```
+
+
+Konfiguracja połączenia do bazy z vaulta
+
+```shell
+vault write database/config/postgresql \
+        plugin_name=postgresql-database-plugin \
+        allowed_roles=readonly \
+        connection_url=postgresql://postgres:secretpassword@$(minikube ip):32543/postgres?sslmode=disable
+```
+
+Utworzenie szablonu roli, którą będzie tworzył vault na bazie danych
+
+```shell
+cat << EOF > /tmp/vault-postgres.sql
+CREATE ROLE "{{name}}" WITH LOGIN PASSWORD '{{password}}' VALID UNTIL '{{expiration}}';
+GRANT SELECT ON ALL TABLES IN SCHEMA public TO "{{name}}";
+EOF
+
+vault write database/roles/readonly db_name=postgresql \
+        creation_statements=@/tmp/vault-postgres.sql \
+        default_ttl=30s max_ttl=60s
+```
+
+Utworzenie polityki zezwalającej na pobieranie danych logowania do bazy
+
+```shell
+cat << EOF > /tmp/postgres-policy.hcl
+path "database/creds/readonly" {
+  capabilities = [ "read" ]
+}
+EOF
+
+vault policy write dbapps /tmp/postgres-policy.hcl
+
+
+vault write auth/kubernetes/role/myapp \
+   bound_service_account_names=app \
+   bound_service_account_namespaces='*' \
+   policies=app,dbapps \
+   ttl=1h
+```
+
+### Weryfikacja
+
+Pobranie tokena
+
+```shell
+APP_TOKEN=$(vault token create -policy="dbapps" -field=token)
+VAULT_TOKEN="$APP_TOKEN" vault read database/creds/readonly
+```
+
+Uruchomienie testowego kontenera z postgresql
+
+```shell
+kubectl run -i --tty --rm debug --image=postgres:alpine --restart=Never -- sh
+```
+
+Dodanie aplikacji z konfiguracją
+
+```shell
+kubectl apply -f krazy-cow.yaml
+kubectl patch deployment krazy-cow --patch "$(cat krazy-cow-patch3.yaml)"
+```
+
+Dane do logowania powinny być w `/vault/secrets` wewnątrz poda.
