New to Docker
Background: I have written a docker-compose.yml which when run with docker-compose up will build and run nicely on my box. Note: my docker-compose.yml downloads the Postgres image.
version: '3'
services:
api:
image: conference_api
container_name: conference_api
build:
context: .
ports:
- 5000:80
environment:
ASPNETCORE_ENVIRONMENT: Production
depends_on:
- postgres
postgres:
image: postgres:9.6.3
container_name: conference_db
environment:
POSTGRES_DB: conference
POSTGRES_USER: conf_app
POSTGRES_PASSWORD: docker
ports:
- 5432:5432
volumes:
- ./db:/docker-entrypoint-initdb.d
I then publish my docker image to docker hub.
On a fresh machine I use docker pull to pull my image and then I run it.
I get errors saying bascially "I can't find the database". The Postgres Image was not also downloaded.
My Question: When I pull my image, how can I get the Postgres image to also download as it is a dependency of my Image.
