I’m dockerizing the app I’ve been working on, but there’s something I’ve been scratching my head trying out to figure out the reason why.
After the database is successfully created with
docker-compose run web rake db:create
Created database 'db_dev' Created database 'db_test'
When I try to run the migration command
docker-compose run web rake db:migrate
database "db_dev" does not exist
If the command is executed again, the migration will be performed.
What could be the reason?
Here is my docker-compose.yml config
version: "3.8" services: db: image: postgres:12.7 volumes: - data:/var/lib/postgresql/data environment: - POSTGRES_HOST_AUTH_METHOD=password - POSTGRES_USER=postgres - POSTGRES_PASSWORD=the_password ports: - "5432:5432" networks: - the_net web: tty: true stdin_open: true build: . image: the_app:latest command: bundle exec rails s -p 3001 -b '0.0.0.0' environment: - DB_HOST=db - DB_USER=postgres - DB_PASSWORD=the_password env_file: - .env volumes: - .:/myapp ports: - "3001:3001" depends_on: - db networks: - the_net volumes: data: networks: the_net: external: true name: the_net
Thanks in advance
