+# SUMMARY:
+#
+# Build and push an image using Docker Buildkit.
+#
+# DESCRIPTION:
+#
+# This does not need privileged access, unlike Docker in Docker (DIND). It has three stages:
+#
+# * clone the Git repository
+# * build the binary
+# * build and push the image containing the binary
+#
+# USAGE:
+#
+# Publishing images requires an access token. For github.com you can create one at https://github.com/settings/tokens
+# This needs to be mounted as `$DOCKER_CONFIG/config.json`. To do this, you'll need to create a secret as follows:
+#
+#    export DOCKER_USERNAME=******
+#    export DOCKER_TOKEN=******
+#    kubectl create secret generic docker-config --from-literal="config.json={\"auths\": {\"https://ghcr.io/\": {\"auth\": \"$(echo -n $DOCKER_USERNAME:$DOCKER_TOKEN|base64)\"}}}"
