Local Kafka setup

http://kafka.apache.org/quickstart contains details to setup and manage Kafka server, below provides details to setup Kafka server in Linux/Mac, Windows will use bat commands in bin/windows instead
download kafka at https://www.apache.org/dyn/closer.cgi?path=/kafka/1.1.0/kafka_2.11-1.1.0.tgz
extract out the downloaded tgz file
go to extracted directory kafka_2.11-0.11.0.1
start ZooKeeper server: bin/zookeeper-server-start.sh config/zookeeper.properties
use another terminal, go to same directory, start the Kafka server: bin/kafka-server-start.sh config/server.properties
note that the zookeeper server is at localhost:2181, and Kafka server is at localhost:9092
use another terminal, go to same directory, create the needed topics: bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic challenge.notification.update
verify that the topics are created: bin/kafka-topics.sh --list --zookeeper localhost:2181, it should list out the created topics
run the producer and then write some message into the console to send to the challenge.notification.update topic: bin/kafka-console-producer.sh --broker-list localhost:9092 --topic challenge.notification.update in the console, write message, one message per line: {"topic":"challenge.notification.update","originator":"topcoder-challenges-api","timestamp":"2019-05-14T00:00:00.000Z","mime-type":"application/json","payload":{"projectId":16640,"terms":[{"id":"317cd8f9-d66c-4f2a-8774-63c612d99cd4","roleId":"732339e7-8e30-49d7-9198-cccf9451e221"}],"task":{"isTask":true,"isAssigned":true,"memberId":"40029484"},"typeId":"ecd58c69-238f-43a4-a4bb-d172719b9f31","legacyId":30058134,"endDate":"2021-01-30T02:09:47.000Z","status":"Completed","trackId":"9b6fc876-f4d9-4ccb-9dfd-419247628825","created":"2021-01-28T02:09:48.677Z","updatedBy":"tcwebservice","createdBy":"jcori","name":"Test Task for Sync","timelineTemplateId":"53a307ce-b4b3-4d6f-b9a1-3741a58f77e6","groups":[],"descriptionFormat":"markdown","updated":"2021-01-28T02:10:55.674Z","phases":[{"phaseId":"6950164f-3c5e-4bdc-abc8-22aaf5a1bd49","duration":86400,"id":"af753aa9-ac3d-4321-b2a8-f183d48cacfe","name":"Submission","isOpen":false,"scheduledStartDate":"2021-01-29T02:09:47.000Z","scheduledEndDate":"2021-01-30T02:09:47.000Z","actualStartDate":"2021-01-29T02:09:47.000Z","actualEndDate":"2021-01-30T02:09:47.000Z"},{"phaseId":"003a4b14-de5d-43fc-9e35-835dbeb6af1f","duration":86400,"id":"bb743041-1226-4686-969e-69f90a01c7fa","name":"Iterative Review","isOpen":false,"predecessor":"af753aa9-ac3d-4321-b2a8-f183d48cacfe","scheduledStartDate":"2021-01-30T02:09:47.000Z","scheduledEndDate":"2021-01-31T02:09:47.000Z","actualStartDate":"2021-01-30T02:09:47.000Z","actualEndDate":"2021-01-31T02:09:47.000Z"},{"phaseId":"ad985cff-ad3e-44de-b54e-3992505ba0ae","duration":86400,"id":"30f0573f-9dc2-4117-825e-ebbf40b96852","name":"Approval","isOpen":false,"predecessor":"bb743041-1226-4686-969e-69f90a01c7fa","scheduledStartDate":"2021-01-31T02:09:47.000Z","scheduledEndDate":"2021-02-01T02:09:47.000Z","actualStartDate":"2021-01-31T02:09:47.000Z","actualEndDate":"2021-02-01T02:09:47.000Z"}],"prizeSets":[{"type":"copilot","prizes":[{"type":"USD","value":1}]},{"type":"placement","prizes":[{"type":"USD","value":10}]}],"startDate":"2021-01-29T02:09:47.000Z","legacy":{"track":"DEVELOP","subTrack":"FIRST_2_FINISH","reviewType":"INTERNAL","confidentialityType":"public","forumId":0,"directProjectId":23678,"isTask":true},"description":"Test","id":"77e031dd-bd35-45f3-bad8-4cc41dbc282f","tags":["Google"],"track":"Development","type":"Task"}}
optionally, use another terminal, go to same directory, start a consumer to view the messages: bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic challenge.notification.update --from-beginning

Local informix setup

Follow the below instructions to setup informix:

$ docker pull appiriodevops/informix
$ docker run --name tc-informix -p 2021:2021 -it appiriodevops/informix

After this go to the docker terminal by runing: docker exec -it tc-informix bash
Switch to informix user: sudo su - informix
Start the db ( https://i.imgur.com/oTeuhOJ.png ) by runing: ./start-informix.sh

Local deployment without Docker

Please make sure you installed and configured kafka and informix

Install all dependencies

Note: ifxnjs doesn't support macos, so it'll install fail. you can't deploy on macos without docker.

npm install

Run the lint

npm run lint

Set environment variables for M2M Token

export AUTH0_CLIENT_ID=jGIf2pd3f44B1jqvOai30BIKTZanYBfU
export AUTH0_CLIENT_SECRET=ldzqVaVEbqhwjM5KtZ79sG8djZpAVK8Z7qieVcC3vRjI4NirgcinKSBpPwk6mYYP

Run the application

npm start

Local Deployment with Docker

Make sure that Kafka in running as instructions above.
Go to docker folder
Create .env file And add below environment for the variables, Please see that 192.168.1.3 is the IP of host machine for docker where we run all the dependencie

AUTH0_CLIENT_ID=jGIf2pd3f44B1jqvOai30BIKTZanYBfU
AUTH0_CLIENT_SECRET=ldzqVaVEbqhwjM5KtZ79sG8djZpAVK8Z7qieVcC3vRjI4NirgcinKSBpPwk6mYYP
KAFKA_URL=192.168.1.3:9092
INFORMIX_HOST=192.168.1.3

If the above don't work, update these configs in config/default.js

Once that is done, go to run the following command

docker-compose up

When you are running the application for the first time, It will take some time initially to download the image and install the dependencies

Verification

Refer to the verification document Verification.md

Notes

you need to use correct createdBy of kafka message values for verification.
