Docker Setup Part 2: Create Docker Containers

Run each executable JAR file built in Part 1

List of executable JAR files:

• Parity System
• Parity Client
• MySQL
• LMA (Local Market Agent and Local Market Manager)
• TEUA (Transactive Energy User Agent)

Overview

1. Create Dockerfile for each application
2. Create required config files
3. Build docker images
4. Run Docker images

Required config and docker file for each application:

System:

In one directory, store these files: Parity System JAR, config file for Parity System, and the Dockerfile for System.

• Example: This directory, which uses the sample configuration file "system0620.conf".

Parity System Config File

market-data {
  session             = parity
  multicast-interface = 192.168.1.50
  multicast-group     = 224.0.0.1
  multicast-port      = 5000
  request-address     = 192.168.1.50
  request-port        = 5001
}

market-report {
  session             = parity
  multicast-interface = 192.168.1.50
  multicast-group     = 224.0.0.1
  multicast-port      = 6000
  request-address     = 192.168.1.50
  request-port        = 6001
}

order-entry {
  address = 192.168.1.50
  port    = 4000
}
...

Parity System Docker File

FROM java:8
WORKDIR <PATH TO JAR & CONF FILE>
ADD parity-system.jar parity-system.jar
ADD system0620.conf system0620.conf
EXPOSE 4000
CMD java -jar parity-system.jar system0620.conf

Parity Client:

In one directory, store these files: Parity Client JAR, config file for Parity Client, and the Dockerfile for Client.

• Example: This directory, which uses the sample configuration file "client0620.conf".

Parity Client Config File

order-entry {
  address  = 192.168.1.50
  port     = 4000
  username = parity
  password = parity
}
...

Parity Client Docker File

FROM java:8
WORKDIR <PATH TO JAR & CONF FILE>
ADD parity-client.jar parity-client.jar
ADD client0620.conf client0620.conf
EXPOSE 39401
EXPOSE 39402
CMD java -jar parity-client.jar 192.168.1.54 client0620.conf

MySQL

In one directory, store these files: SQL file to create the database, and the Dockerfile for MySQL

SQL file

CREATE DATABASE IF NOT EXISTS nist_cts_eml;
USE nist_cts_eml;

DROP TABLE IF EXISTS `hibernate_sequence`;
CREATE TABLE `hibernate_sequence` (
  `next_val` bigint DEFAULT NULL
);

DROP TABLE IF EXISTS `position`;
CREATE TABLE `position` (
  `counter_id` bigint NOT NULL,
  `end_time` datetime NOT NULL,
  `position_party` bigint DEFAULT NULL,
  `quantity` bigint DEFAULT NULL,
  `start_time` datetime NOT NULL,
  `transaction_id` bigint DEFAULT NULL,
  PRIMARY KEY (`counter_id`)
);


LOCK TABLES `hibernate_sequence` WRITE;
INSERT INTO `hibernate_sequence` VALUES (1);
UNLOCK TABLES;

MySQL Dockerfile

FROM mysql:latest

ENV MYSQL_ROOT_PASSWORD capstone@123
ENV MYSQL_DATABASE nist_cts_eml
ENV MYSQL_USER eml
ENV MYSQL_PASSWORD capstone@123
ADD <SQL file name>.sql /docker-entrypoint-initdb.d/<SQL file name>.sql
RUN chmod -R 775 /docker-entrypoint-initdb.d

LMA

In one directory, keep all these files: LMA jar & DockerFile for LMA

LMA Dockerfile

FROM java:8
WORKDIR <PATH TO JAR FILE>
ADD lmma.jar lmma.jar
EXPOSE 8080
EXPOSE 39401
EXPOSE 39402
CMD java -jar lmma.jar

TEUA

In one directory, keep all these files: TEUA jar & DockerFile for TEUA

TEUA Dockerfile

FROM java:8
WORKDIR <PATH TO JAR FILE>
ADD teua.jar teua.jar
EXPOSE 8080
CMD java -jar teua.jar

Setup

1. Create docker images

Parity System:

• For Windows - docker build -t system:1.0 <PATH TO SYSTEM DOCKER FILE>
• For Mac - docker build --tag system:1.0 <PATH TO SYSTEM DOCKER FILE>

Parity Client:

• For Windows - docker build -t client:1.0 <PATH TO CLIENT DOCKER FILE>
• For Mac - docker build --tag client:1.0 <PATH TO CLIENT DOCKER FILE>

LMA:

• For Windows - docker build -t lma:1.0 <PATH TO LMA DOCKER FILE>
• For Mac - docker build --tag lma:1.0 <PATH TO LMA DOCKER FILE>

TEUA:

• For Windows - docker build -t teua:1.0 <PATH TO TEUA DOCKER FILE>
• For Mac - docker build --tag teua:1.0 <PATH TO TEUA DOCKER FILE>

2. Create a docker network to run the container in with this command: docker network create --subnet=192.168.1.1/24 ctsnet

3. Run the newly created System Docker image inside a container using the specified IP with this command: docker run --net ctsnet --ip 192.168.1.50 --name systemcontainer1 system:1.0

4. Run the newly created Client Docker image inside a container using the specified IP with this command: docker run --net ctsnet --ip 192.168.1.51 -i -t --name clientcontainer1 client:1.0

5. Run MySQL:

   1. Approach 1: using mysql image and set up

      • Pull mysql docker image: docker pull mysql
      • Run the newly created MySQL Docker image inside a container using the specified IP with this command: docker run --net ctsnet --ip 192.168.1.53 --name mysqlctsnet -p 3306:3306 -e MYSQL_ROOT_PASSWORD=capstone@123 mysql
      • Open MySQL console in docker using this command: docker exec -it mysqlctsnet bash
      • Enter credentials in MySQL console using this command: mysql -u root -pcapstone@123
      • Create/setup database and user using following command:
        • To create database: create database nist_cts_eml;
        • To create user: create user eml@192.168.1.54 identified by "";
        • To grant full access of database to user: grant all on nist_cts_eml.* to eml@192.168.1.54;
        • To set password for user: SET PASSWORD FOR 'eml'@'192.168.1.54' = 'capstone@123';

   2. Approach 2: using docker file of MySQL:

      • Build Docker image: docker build --tag mysql:1.0 <PATH TO MYSQL DOCKER FILE>
      • Run MYSQL from docker image: docker run --net ctsnet --ip 192.168.1.53 --rm --name eml-mysql -p 3306:3306 mysql:1.0
      • Note: In case of error (Bind: Address already in use), run sudo service mysql stop then run MYSQL from docker image again.

6. Run the newly created LMA Docker image inside a container using the specified IP with this command: docker run --net ctsnet --ip 192.168.1.54 --name lmmacontainer1 lma:1.0

7. Run the newly created TEUA Docker image inside a container using the specified IP with this command: docker run --net ctsnet --ip 192.168.1.55 -p 8080:8080 --name teuacontainer1 teua:1.0
