📖 Step By Step Guide

Local Docker Environment Setup:

sh docker-start.sh

• this script will build all spring boot docker images and start environment with your code changes

sh docker-restart.sh

• this script will restart all docker containers without rebuilding images

sh docker-app-restart.sh video

• this script will rebuild spring boot docker image for video application and restart application with rebuilt image
• replace video with the name of the application you want to rebuild and restart

sh docker-worker-restart.sh

• this script will rebuild spring boot docker image for worker application and restart application with rebuilt image
• worker uses custom Dockerfile image to pre-install FFmpeg Tool. Therefore, it should be rebuilt with custom script
• actual rebuild of worker docker image happens in docker-app-compose.yml file (see build: "./worker-service")

Local Docker Environment Acceptance Test:

1. run sh docker-start.sh

2. run commands in ./command.txt (Debezium Kafka PostgreSQL connectors)

3. open http://localhost:9000 in your Browser

• For authorized requests: click Authorize and use admin/admin or user/user for credentials (clientId should be video-app)

4. goto http://localhost:9000/webjars/swagger-ui/index.html#/storage-controller/upload and upload mp4 file (you can use test.mp4 in worker-service folder for testing)

5. goto http://localhost:9000/webjars/swagger-ui/index.html#/video-controller/create and create video with filename from step 4, please copy the video id from response

6. goto http://localhost:9000/webjars/swagger-ui/index.html#/video-controller/profile with video id and wait for the video status to become READY

7. use http://localhost:9000/video/api/video/{your_video_id}/index.m3u8 for any HLS player (alternatively, download links in m3u8 file and open them with any video player)

• Congratulations! You successfully tested Swagger UI Gateway and Video Streaming API!

Remote Debugging

Minio File Storage Server

• Minio File Storage Server should be available here: http://localhost:8086/

• If acceptance testing was successful, then stream and video Buckets should exist and contain video files

• You can download and browse video files using this console

Kafka UI

• Kafka UI should be available here: http://localhost:8070/
• You can browse topics, partitions, messages and other kafka resources using this console

Zipkin Server

• Zipkin Server for Distributed Tracing should be available here: http://localhost:9411/
