+# Optional environment variables:
+#
+# - KANIKO_BUILD_IMAGENAME: Build/target image name.
+#   If empty, image URL will be the root of the gitlab project path, i.e.
+#     `open.greenhost.net:4567/GROUP/PROJECT:TAG
+#   Is set, images will be named like
+#     `open.greenhost.net:4567/GROUP/PROJECT/KANIKO_BUILD_IMAGENAME:TAG
+#
+# - KANIKO_CONTEXT: The subdir which holds the Dockerfile, leave unset if
+#                   the Dockerfile is located at root level of the project.
+#
+# - KANIKO_ADDITIONAL_ARGS: This variable allows you to pass in ARG values that
+#   are used at build time. Similarly to Docker you can specify multiple arguments
+#   using the format `--build-arg NAME=VALUE` as many times as you need.
+#
+# - KANIKO_TAG: Allows to override the name of the resulting image tag
