I created a transaction processor using javascript sawtooth-sdk. When i run it locally, it works successfully and it gives me this message when running locally (By locally means running the javascript file using node index.js).
Connecting to Sawtooth validator at tcp://localhost:4004
Connected to tcp://localhost:4004
Registration of [myTP 1.0] succeeded
Then i dockerized it and when i start the container, it doesn't connect. It only has
Connecting to Sawtooth validator at tcp://localhost:4004
message. When i check the Sawtooth docker logs, there were no logs
My docker base image is FROM ubuntu:bionic and i expose EXPOSE 4004/tcp like this. What might be the problem? I know its coming from validator and what i cant understand is that this work locally and doesn't work in the docker file.
Looks like the application container and docker-compose containers are residing in 2 different networks.
Find your network (probably this will be the name of the project directory)
docker network ls
Then connect the application container to the same network used by the compose
docker network connect <network> <app container>
If you need to do this in the start up of the app container,
docker run -itd --network=<network name> <app image>
Then, form the application, you can call the validator container name and connect,
tcp://sawtooth-validator-default:4004
