+# Introduction to Kubernetes: Secrets
+
+## Create a cluster with Kind
+
+```
+kind create cluster --name secrets --image kindest/node:v1.31.1
+```
+
+## Our Secret
+
+We have a secret under `kubernetes/secrets/secret.json`
+
+```
+cat kubernetes/secrets/secret.json
+```
+
+## Using our secret in a container
+
+As a file:
+```
+docker run -it -v $PWD/kubernetes/secrets/secret.json:/secrets/secret.json ubuntu:latest bash
+
+cat /secrets/secret.json
+```
+
+As environment variables:
+
+```
+api_key="somesecretgoeshere"
+docker run -it -e API_KEY=$api_key ubuntu:latest bash
+
+echo $API_KEY
+```

+
+## Create our secret
+
+There are two main ways we can create a Kubernetes secret. </br>
+Either by creating the secret object with `kubectl create secret` or apply\create it declaratively using YAML with `kubectl apply -f`
+
+`kubectl create secret`:
+
+```
+kubectl create secret generic mysecret --from-file kubernetes/secrets/secret.json
+```
+
+`kubectl apply -f` or `kubectl create -f` allows us to define things declaratively using YAML files:
+
+```
+kubectl apply -f kubernetes/secrets/secret.yaml
+```
+
+## Use our secret
+
+In order to use our secret we add a `volume` to our pod spec and then mount that using a `volumeMount` </br>
+We can also use a secret references as `env` variable </br>
+
+
+```
+kubectl apply -f kubernetes/secrets/pod.yaml
+```
