-# MariaDB MaxScale Docker image
+# Real World Project CNE 370
 
-This Docker image runs the latest 2.4 version of MariaDB MaxScale.
 
--	[Travis CI:  
-	![build status badge](https://img.shields.io/travis/mariadb-corporation/maxscale-docker/master.svg)](https://travis-ci.org/mariadb-corporation/maxscale-docker/branches)
 
+## Overview
 
-## Building
+This project utilizes docker-compose containers running MaxScale to create a sharded SQL database containing zipcode information. A python script is then used to  connect, query, and demonstrate the merged database.
 
-Run the following command in this directory to build the image.
+## Configuration
+
+### docker-compose.yml
+
+This file is used as a blueprint to build your docker containers. You can specify how many and what type of containers you want to build.
+
+### maxscale.cnf
+
+This file configures your MaxScale instance. Docker-compose.yml calls upon this file to build the MaxScale container.
+
+### Shard_query.py
+
+This is the Python script. You can configure it to retrieve specific data from the database.
+
+## Building Container and Running Code
+
+Go into the /maxscale directory and run the following to build your containers
 
 ```
-make build-image
+sudo docker-compose up -d
 ```
 
-## Running
-To pull the latest MaxScale image from docker hub:
+Confirm that your containers have been successfully built. You should see the containers you've specified in docker-compose.yml.
 ```
-docker pull mariadb/maxscale:latest
+sudo docker-compose ps
 ```
 
-To run the MaxScale container overriding the container instance name to 'mxs':
+Install python3 and pymysql
+
 ```
-docker run -d --name mxs mariadb/maxscale:latest
+sudo apt-get install python3.6
+sudo apt-get install python3-pymysql
 ```
 
-Read on for details of how to configure the MaxScale container.
-
-## Configuration
-The default configuration for the container is fairly minimalist and can be found in [this configuration file](./maxscale.cnf). At a high level the following is enabled:
-- REST API with default user and password (admin / mariadb) listening to all hosts (0.0.0.0)
+Go into the /Real_world_project_CNE370 directory and run the following to execute the python script
 
-### Configure via REST API
-The REST API by default listens on port 8989. To interact with this from the docker host, requires a port mapping to specified on container startup. The example below shows listing the current services via curl:
 ```
-docker run -d -p 8989:8989 --name mxs mariadb/maxscale:latest
-curl -u admin:mariadb -H "Content-Type: application/json" http://localhost:8989/v1/services
-
+python3 zipcode.py 
 ```
-### Configure via maxscale.cnf File
-An alternative model is to provide an overlay maxscale.cnf file that provides additional configuration for the cluster to be managed. To do this, you must mount your configuration file into `/etc/maxscale.cnf.d/`. When running the container with docker directly pass this using the argument to the `-v` option:
+Results 
 
 ```
-docker run -d --name mxs -v $PWD/my-maxscale.cnf:/etc/maxscale.cnf.d/my-maxscale.cnf mariadb/maxscale:2.2

-## MaxScale docker-compose setup
 
-[The MaxScale docker-compose setup](./docker-compose.yml) contains MaxScale
-configured with a three node master-slave cluster. To start it, run the
-following commands in this directory.
 
-```
-docker-compose build
-docker-compose up -d
-```
 
-After MaxScale and the servers have started (takes a few minutes), you can find
-the readwritesplit router on port 4006 and the readconnroute on port 4008. The
-user `maxuser` with the password `maxpwd` can be used to test the cluster.
-Assuming the mariadb client is installed on the host machine:
-```
-$ mysql -umaxuser -pmaxpwd -h 127.0.0.1 -P 4006 test
-Welcome to the MariaDB monitor.  Commands end with ; or \g.
-Your MySQL connection id is 5
-Server version: 10.2.12 2.2.9-maxscale mariadb.org binary distribution
 
-Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
 
-Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
 
-MySQL [test]>
-```
-You can edit the [`maxscale.cnf.d/example.cnf`](./maxscale.cnf.d/example.cnf)
-file and recreate the MaxScale container to change the configuration.
 
-To stop the containers, execute the following command. Optionally, use the -v
-flag to also remove the volumes.
 
-To run maxctrl in the container to see the status of the cluster:
-```
-$ docker-compose exec maxscale maxctrl list servers
-┌─────────┬─────────┬──────┬─────────────┬─────────────────┬──────────┐
-│ Server  │ Address │ Port │ Connections │ State           │ GTID     │
-├─────────┼─────────┼──────┼─────────────┼─────────────────┼──────────┤
-│ server1 │ master  │ 3306 │ 0           │ Master, Running │ 0-3000-5 │

-└─────────┴─────────┴──────┴─────────────┴─────────────────┴──────────┘
 
-```
 
-The cluster is configured to utilize automatic failover. To illustrate this you can stop the master
-container and watch for maxscale to failover to one of the original slaves and then show it rejoining
-after recovery:
-```
-$ docker-compose stop master
-Stopping maxscaledocker_master_1 ... done
-$ docker-compose exec maxscale maxctrl list servers
-┌─────────┬─────────┬──────┬─────────────┬─────────────────┬─────────────┐

-└─────────┴─────────┴──────┴─────────────┴─────────────────┴─────────────┘
 
-```
 
-Once complete, to remove the cluster and maxscale containers:
 
-```
-docker-compose down -v
-```
