Docker image for Monasca Log API
|
||||
================================
|
||||
The Monasca log API image is based on the monasca-base image.
|
||||
|
||||
|
||||
Building monasca-base image
|
||||
===========================
|
||||
See https://github.com/openstack/monasca-common/tree/master/docker/README.rst
|
||||
|
||||
|
||||
Building Monasca log API image
|
||||
==============================
|
||||
|
||||
Example:
|
||||
$ ./build_image.sh <repository_version> <upper_constains_branch> <common_version>
|
||||
|
||||
|
||||
Requirements from monasca-base image
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
health_check.py

|
||||
application.
|
||||
|
||||
|
||||
Scripts
|
||||
~~~~~~~
|
||||
start.sh
|
||||
In this starting script provide all steps that lead to the proper service
|
||||
start. Including usage of wait scripts and templating of configuration
|
||||
files. You also could provide the ability to allow running container after
|
||||
service died for easier debugging.
|
||||
|
||||
build_image.sh
|
||||
Please read detailed build description inside the script.
