# Kubernetes Mutating Webhook for ImagePullSecret injection in ServiceAccounts
The responsibility of this webhook is to patch all newly created/updated service account and make sure they all contained proper imagepullsecret configuration.
## Helm description
The helm chart consists of 2 parts: the certificate generator and the webhook configuration itself.
Certificate generation part periodically generates certificates signed by kubernetes' CA and passes them to the webhook where they are used as server-side certificates. The flow works roughly like this:
1. We generate a CSR using openssl and tie the certificate to the webhook's service DNS.
1. We create a k8s CertificateSigningRequest from the openssl CSR.
1. We approve this request using our special ServiceAccount with approve permissions. This makes kubernetes issue the certificate
1. We fetch the certificate from the k8s CSR (at `.status.certificate`) and create a secret from it
1. We also create a CronJob that does this periodically as k8s only issues certificates for 1 year
The main part is the deployment and the web hook configuration. The flow is as follows
1. The MutatingWebhookConfiguration we create instructs k8s to pass all requests for creating/updating all ServiceAccounts to our webhook before finishing the request
1. We check whether the SA has the correctly defined imagepullsecret configuration. if not, we create a patch for the resource
1. We also check whether we have the secret we are using in the imagepullsecret in the SA's namespace. If not, we create it based on our source secret
1. We return the patch to k8s, which applies the changes
Of note is also a fact that the chart runs a lookup to the connected cluster to fetch the CA bundle for the MutatingWebhook. This means `helm template` won't work.
## Running locally
```bash
kubectl create ns imagepullsecret-injector
kubectl create secret -n imagepullsecret-injector \
generic my-cool-secret-source \
--from-literal=.dockerconfigjson='<your .dockerconfigjson configuration file>'
make build-image
helm upgrade -i imagepullsecret-injector \
--create-namespace -n imagepullsecret-injector \
helm/imagepullsecret-injector
```
To test whether everything works, you can run
```bash
kubectl create ns yolo
kubectl get sa -n yolo default -ojsonpath='{.imagePullSecrets}'
```
The get command should display _some_ non-empty result.

description: A Helm chart for Kubernetes
# A chart can be either an 'application' or a 'library' chart.
#
# Application charts are a collection of templates that can be packaged into versioned archives
# to be deployed.
#
# Library charts provide useful utilities or functions for the chart developer. They're included as
# a dependency of application charts to inject those utilities and functions into the rendering
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
type: application
# This is the chart version. This version number should be incremented each time you make changes
# to the chart and its templates, including the app version.
# Versions are expected to follow Semantic Versioning (https://semver.org/)
version: 0.0.1
# This is the version number of the application being deployed. This version number should be
# incremented each time you make changes to the application. Versions are not expected to
# follow Semantic Versioning. They should reflect the version the application is using.
