[Help] Config and docker-compose about typeorm HOT 8 CLOSED

@jcloutz you can also load the .env file within docker-compose using env_file instead of enumerating each value:

version: '3.1'

services:
  pgsql:
    image: postgres:9
    ports:
      - ${TYPEORM_PORT}:5432
    env_file:
      - .env
    volumes:
      - pg_data:/var/lib/postgres/data

volumes:
  pg_data:

@otroboe another cool thing you can do with direnv is create shell scripts for a specific project and modify the path for the current working directory.

This works like a charm with typeorm, i got annoyed having to invoke ts-node everytime i wanted to create or run migrations.

#!/bin/bash
#/path/to/program/bin/typeorm

./node_modules/.bin/ts-node ./node_modules/.bin/typeorm $1 $2 $3 $4 $5

You don't need to do that with docker-compose, it loads the .env file automatically.

I'm closing it, it's not related to Nest, but TypeORM :-)

@otroboe Take a look at using a .env file for config. It has some limitations with typeorm if you want to use more than one database but it should get the job done in most cases

Docker Compose Environment Vars & Typeorm

If you couple with something like Direnv to parse the .env file when you enter the directory it should work out pretty good.

# .env
HOST=localhost
PORT=8000
NODE_ENV=development
LOG_LEVEL=debug

TYPEORM_CONNECTION=postgres
TYPEORM_HOST=localhost
TYPEORM_USERNAME=postgres
TYPEORM_PASSWORD=postgres
TYPEORM_DATABASE=project_database
TYPEORM_PORT=5432
TYPEORM_SYNCHRONIZE=false
TYPEORM_DROP_SCHEMA=false
TYPEORM_LOGGING=all
TYPEORM_ENTITIES=src/common/entity/**/*.ts
TYPEORM_MIGRATIONS=src/database/migrations/**/*.ts
TYPEORM_SUBSCRIBERS=src/database/subscribers/**/*.ts

# .envrc used for direnv to modify shell when entering directory

# add {project_dir}/bin to path for helpers
export PATH=$(PWD)/bin:$PATH

# parse .env file when entering project dir
export $(egrep -v '^#' .env | xargs)

version: '3.1'

services:
  pgsql:
    image: postgres:9
    ports:
      - ${TYPEORM_PORT}:5432
    environment:
      POSTGRES_PASSWORD: ${TYPEORM_PASSWORD}
      POSTGRES_DB: ${TYPEORM_DATABASE}
    volumes:
      - pg_data:/var/lib/postgres/data

Thank you ! I'll test your solution as soon as I can.

@otroboe That's convenient! I guess in my habit of being explicit with Docker, that nuance got lost on me.

You can still use the env_file option for files not called .env ;-)
Like if you need different env files for each container.
