icap-service

icap-service

This is the service of this repo that at like middleware between icap-server and processing service

Steps of processing

When it starts

• Listens on the queue
• Get the file from the queue
• upload it to minio bucket
• Push the file details to the queue

Configuration

• This pod need to mount the share storage mounted on icap server and that is how they will share the file together
• It's possible to have multiple replica of this service running. Only one will get the file and process it

Docker build

• To build the docker image

git clone https://github.com/k8-proxy/go-k8s-srv.git
cd k8-proxy/go-k8s-srv
docker build -t <docker_image_name> .

build

• First make sure that you have rabbitmq and minio running.
• For quick start using docker to run containers for RabbitMQ and MinIO.
• Run Standalone MinIO on Docker.

docker run -e "MINIO_ROOT_USER=<minio_root_user_name>" \
-e "MINIO_ROOT_PASSWORD=<minio_root_password>" \
-d -p 9000:9000 minio/minio server /data

• Run RabbitMQ on Docker.

docker run -d --hostname <host_name> --name <container_name> -p 15672:15672 -p 5672:5672 rabbitmq:3-management

• To run the container

docker run -e ADAPTATION_REQUEST_QUEUE_HOSTNAME='<rabbit-host>' \
-e ADAPTATION_REQUEST_QUEUE_PORT='<rabbit-port>' \
-e MESSAGE_BROKER_USER='<rabbit-user>' \
-e MESSAGE_BROKER_PASSWORD='<rabbit-password>' \
-e MINIO_ENDPOINT='<minio-endpoint>' \
-e MINIO_ACCESS_KEY='<minio-access>' \
-e MINIO_SECRET_KEY='<minio-secret>' \
-e MINIO_SOURCE_BUCKET='<bucket-to-upload-file>' \
-e MINIO_CLEAN_BUCKET='<bucket-to-upload-file>' \
-e TRANSACTION_STORE_PATH='<path-to-report-file>' \
--name <docker_container_name> <docker_image_name>

• Please note that in the previous command:

  • To get the variable <rabbit-host> run:

  docker inspect <rabbitmq_container_name>
  

  • It will be the value of key: IPAddress

  • the same as for Minio

  • To get the variable <minio-endpoint> run:

  docker inspect <minio_container_name>
  

  • It will be the value of key: IPAddress

Testing steps

• Run the containers as mentionned above
• Be sure that there is a bucket with the same name you entered for <bucket-to-upload-file> among MinIO buckets.
• Publish data reference to rabbitMq on queue name : adaptation-request-queue with the following data(table):

• file-id : An ID for the file
• source-file-location : The full path to the file
• rebuilt-file-location : A full path representing the location where the rebuilt file will go to

• Check your container logs to see the processing

docker logs <container name>
