===============================
|
||||
Docker image for Monasca Client
|
||||
===============================
|
||||
The Monasca Client 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 Client image
|
||||
=============================
|
||||
|
||||
Example:
|
||||
$ ./build_image.sh <repository_version> <upper_constains_branch> <common_version>
|
||||
|
||||
|
||||
Requirements from monasca-base image
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
health_check.py
|
||||
This file will be used for checking the status of the Monasca API
|
||||
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.
|
||||
|
||||
|
||||
Docker Compose
|
||||
~~~~~~~~~~~~~~
|
||||
When you want to use docker-compose add it as a new service and be sure that
|
||||
property 'tty' is set to true to avoid exiting of container after startup.
|
||||
Example:
|
||||
|
||||
* monasca-client:
|
||||
* image: monasca/client:master
|
||||
* tty: true
|
||||
|
||||
Running
|
||||
~~~~~~~
|
||||
If you don't want to use docker-compose mechanism, you can run container manually
|
||||
and connect it to existing docker Monasca network.
|
||||
Example:
|
||||
docker network --network=<network-name> <container_name>
|
||||
|
||||
You can also use docker run option to start a container and connect it to a network immediately:
|
||||
Example:
|
||||
docker run -itd --network=<network-name> <container-name>
|
||||
|
||||
Inside of container it is possible to run 'monasca' shell commands, e.g. to list all metrics.
|
||||
Example:
|
||||
monasca metric-list

#

# Everything after `./build_image.sh` is optional and by default configured

# $ ./build_image.sh stable/queens
|

|

# $ ./build_image.sh cb7f226
|

# $ ./build_image.sh 2.5.0

# $ ./build_image.sh refs/changes/51/558751/1 stable/queens
|

#
|
||||
# If you want to build image with custom monasca-common version you need

|

# $ ./build_image.sh master master refs/changes/19/595719/3
