+# Chaincode job
+
+The k8s builder runs chaincode images using a long running [Kubernetes job](https://kubernetes.io/docs/concepts/workloads/controllers/job/). Using jobs instead of bare pods [enables Kubernetes to clean up chaincode pods automatically](https://kubernetes.io/docs/concepts/workloads/controllers/ttlafterfinished/).
+
+The k8s builder uses labels and annotations to help identify the Kubernetes objects it creates.
+
+## Labels
+
+Kubernetes objects created by the k8s builder have the following labels.
+
+app.kubernetes.io/name[^1]
+
+: The name of the application, `hyperledger-fabric`
+
+app.kubernetes.io/component[^1]
+
+: The application component, `chaincode`
+
+app.kubernetes.io/created-by[^1]
+
+: The tool that created the object, `fabric-builder-k8s`
+
+app.kubernetes.io/managed-by[^1]
+
+: The tool used to manage the application, `fabric-builder-k8s`
+
+fabric-builder-k8s-cclabel
+
+: The chaincode label, e.g. `mycc`
+
+fabric-builder-k8s-cchash
+
+: Base32 encoded chaincode hash, e.g. `U7FELJ6MQXY5RHEQLN3VSIBWD3IITI3E4EVJW3KVXJ24SZO522UQ`
+
+    The chaincode hash is base32 encoded so that it fits in the maximum number of characters allowed for a Kubernetes label value. For example, if you have the chaincode package ID, use the following commands to base32 encode the chaincode hash.
+
+    ```shell
+    echo $PACKAGE_ID | cut -d':' -f2 | xxd -r -p | base32 | tr -d '='
+    ```
+
+[^1]:
+    Kubernetes defines [recommended labels](https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/) to describe applications and instances of applications.
+
+## Annotations
+
+Kubernetes objects created by the k8s builder have the following annotations.
+
+fabric-builder-k8s-ccid
+
+: The full chaincode package ID, e.g. `mycc:a7ca45a7cc85f1d89c905b775920361ed089a364e12a9b6d55ba75c965ddd6a9`
+
+fabric-builder-k8s-mspid
+
+: The membership service provider ID, e.g. `DigiBank`
+
+fabric-builder-k8s-peeraddress
+
+: The peer address, e.g. `peer0.digibank.example.com`
+
+fabric-builder-k8s-peerid
+
+: The peer ID, e.g. `peer0`
+

+
+If you are only planning to use the k8s builder and do not need to fallback to the legacy Docker build process for any chaincode, check your `core.yaml` file for the `vm.endpoint` Docker endpoint configuration shown below and remove it if necessary.
+
+```yaml
+vm:
+  # Endpoint of the vm management system.  For docker can be one of the following in general
+  # unix:///var/run/docker.sock
+  # http://localhost:2375
+  # https://localhost:2376
+  # If you utilize external chaincode builders and don't need the default Docker chaincode builder,
+  # the endpoint should be unconfigured so that the peer's Docker health checker doesn't get registered.
+  endpoint: unix:///var/run/docker.sock
 ```
