Connect Tarantool Docker image to Postgres

Question

I'm trying to connect Tarantool Docker Image to local PostgreSQL, to replicate some test data, and ran into the following problems:

1. It seems there is no CL (except Tarantool console) to check which files are in place (exec bin/bash fails)
2. pg = require('pg') leads to an error: "init.lua:4: module 'pg.driver' not found", despite the presence of the pg module in the Docker description
3. I have doubts about how to replicate efficiently 4 tables, and relations between them, to the container from outside Postgres

Does anyone know sources to dig in and find solutions to those problems? Any direction would be greatly appreciated.

Answer 1

1. docker exec -ti tnt_container sh
2. the issue. You should find an older base image or build it yourself.
3. This is PostgreSQL-related doubts. You may pass batches of data to pg functions or use intermediate application to transfer data via COPY. It looks like tarantool's pg driver does not support COPY.
