Load Postgres dump after docker-compose up

Question

I have a dump.sql file that I would like to load with docker-compose. docker-compose.yml: services: postgres: environment: POSTGRES_DB: my_db_name POSTGRES_USER: my_name POSTGRES_PASSWORD: my_password build: context: . dockerfile: ./devops/db/Dockerfile.db My Dockerfile.db is really simple at the moment: FROM postgres MAINTAINER me COPY ./devops/db ./devops/db WORKDIR ./devops/db I would like to run a command like psql my_db_name < dump.sql at some point. If I run a script like this from the Dockerfile.db, the issue is that the script is run after build but before docker-compose up, and the database is not running yet. Any idea how to do this? Select the correct answer from above options

Answer 1

After going through the documentation https://hub.docker.com/_/postgres/ It explains that any .sql in /docker-entrypoint-initdb.d will be executed after build. For this, you just need to make small changes in Dockerfile.db FROM postgres ADD ./devops/db/dummy_dump.sql /docker-entrypoint-initdb.d This will work for your query.
