+# Kubelet ECR Credential Provider extension
+
+This extension provides the [ecr-credential-provider](https://github.com/kubernetes/cloud-provider-aws/tree/master/cmd/ecr-credential-provider) binary,
+which can be executed by Kubelet to provide a short-lived token for pulling container images
+from Amazon Web Services' Elastic Container Registry (ECR).
+
+## Installation
+
+See [Installing Extensions](https://github.com/siderolabs/extensions#installing-extensions).
+
+You also need to configure `ecr-credential-provider` as a Kubelet image
+credential provider. For this you'll need to add two Kubelet arguments:
+
+```yaml
+- op: add
+  path: /machine/kubelet/extraArgs
+  value:
+    image-credential-provider-bin-dir: "/usr/local/lib/kubelet/credentialproviders"
+    image-credential-provider-config: "/var/lib/kubelet/credentialproviderconfig.yaml"
+```
+
+You'll also need to mount the binary to the kubelet container:
+
+```yaml
+- op: add
+  path: /machine/kubelet/extraMounts
+  value:
+    - destination: /usr/local/lib/kubelet
+      type: bind
+      source: /usr/local/lib/kubelet
+      options: [bind, ro]
+```
+
+and then create the `CredentialProviderConfig`:
+
+```yaml
+- op: add
+  path: /machine/files
+  value:
+    - op: create
+      path: /var/lib/kubelet/credentialproviderconfig.yaml
+      content: |
+        apiVersion: kubelet.config.k8s.io/v1
+        kind: CredentialProviderConfig
+        providers:
+          - name: ecr-credential-provider
+            matchImages:
+              - "*.dkr.ecr.*.amazonaws.com"
+              - "*.dkr.ecr.*.amazonaws.com.cn"
+              - "*.dkr.ecr-fips.*.amazonaws.com"
+              - "*.dkr.ecr.us-iso-east-1.c2s.ic.gov"
+              - "*.dkr.ecr.us-isob-east-1.sc2s.sgov.gov"
+            defaultCacheDuration: "12h"
+            apiVersion: credentialprovider.kubelet.k8s.io/v1
+```
