+======================================
+Docker base image for Monasca services
+======================================
+
+This image is used as a starting point for images of all Monasca services.
+
+
+Building monasca-base
+=====================
+
+You need to have Docker installed (minimum supported version is ``17.09``).
+Then you could build image inside of this folder:
+
+``docker build --no-cache -t monasca-base:1.0.0 .``
+
+
+Building child image
+--------------------
+
+In the ``example`` folder you could file sample of how to start building
+new child image using ``monasca-base`` as start.
+
+Requirements
+~~~~~~~~~~~~
+
+Every child image need to provide two files:
+
+start.sh
+  In this starting script provide all steps that direct to proper service
+  start. Including usage of wait scripts and templating of configuration files.
+  You also could provide ability to allow running container after service died
+  for easier debugging.
+
+health_check.py
+  This file will be used for checking status of application running in the
+  container. It will be useful for programs like Kubernetes or Docker Swarm
+  to properly handle services that are still running but stopped being
+  responsive. Avoid using `curl` directly and instead use `health_check.py`
+  written with specific service in mind. It will provide more flexibility
+  like when creating JSON request body.
+
+
+Wait scripts
+------------
+
+Some Python libraries are already preinstalled: `pykafka` and `PyMySQL`.
+They are used by wait scripts and in the process of creating child image
+`pip3` will reinstall them to proper versions confronting to upper constraints
+file.
+
+This wait scripts will be available in every child image and could be used in
+`start.sh` to avoid unnecessary errors and restarts of containers when they
+are started.
+
+::
+
+    python3 /kafka_wait_for_topics.py || exit 1
+    python3 /mysql_check.py || exit 1
+    /wait_for.sh 192.168.10.6:5000 || exit 1
+
+Please, check content of every of this files for documentation of what
+environment variables are used and more usage examples.
+
+
+Useful commands
+---------------
+
+List all labels on image (you need to have ``jq`` installed):
+
+``docker inspect monasca-api:master | jq .[].Config.Labels``
+
+Get all steps from what Docker image was build:
+
+::
+
+    docker history --no-trunc <IMAGE_ID>
+    docker history --no-trunc monasca-base:1.0.0
