Running the media service application

Before you start

• Install Docker and Docker Compose.
• Make sure the following ports are available: port 8080 for Nginx frontend and 16686 for Jaeger,4080 and 5563 for X-Trace.

Build modified containers

By default, the DeathStarBench pulls its containers from docker hub. We need to override these with our modified X-Trace containers. To do this, we will manually build the docker images for the modified components.

1. Build the base docker image that contains all the dependent libraries. We modified this to add X-Trace and protocol buffers.

cd docker/thrift-microservice-deps/cpp
docker build --no-cache -t yg397/thrift-microservice-deps .
cd ../../..

2. Build the nginx server image. We modified this to add X-Trace and protocol buffers

cd docker/openresty-thrift
docker build --no-cache -t yg397/openresty-thrift -f xenial/Dockerfile .
cd ../../../

3. Build the social network docker image

docker build -t yg397/media-microservices .

Start docker containers

Start docker containers by running docker-compose up -d. All images will be pulled from Docker Hub.
