docker compose for timescaledb and postgresql-adaptor

timescaledb-timescaledb-postgresql-adaptor-docker-compose.yml

I choosed host path mapping for postgresql data directory in a separate OS disk to be able to resize partition later.
You can use docker standart volumes too.

# mkdir -p /data/timescaledb

# cat docker-compose.yml 
version: '3'

services:
  timescaledb:
    image: timescale/timescaledb:latest-pg12
    restart: always
    ports:
      - 5432:5432
    environment:
      POSTGRES_USER: timescaledb
      POSTGRES_PASSWORD: password
    volumes:
      - /data/timescaledb:/var/lib/postgresql/data
