Description

This project is a Go language learning project with simple RestFul services. It uses postgres db inside with docker-compose. You can compose with dockerfile or create your own postgres database without it.

For run docker-compose, you need to write following commands. In your project folder,

      cd docker
      docker-compose up

then PostgreSQL works on 32300 Port (32300 -> 5432). You can access with database IDE (DataGrip, Intellij etc.) with configure port 32300.

If you want to conncect from your host system type the following command to terminal.

      psql -h localhost -p 32300 -d docker -U docker --password

For more information about it,

Dockerize PostgreSQL

Database table configuration

      CREATE TABLE USERS (
        ID INT PRIMARY KEY,
        NAME TEXT NOT NULL,
        SURNAME TEXT NOT NULL,
        AGE INT NOT NULL
      );
      
      CREATE SEQUENCE public.users_id_seq NO MINVALUE NO MAXVALUE NO CYCLE;
      ALTER TABLE public.users ALTER COLUMN id SET DEFAULT nextval('public.users_id_seq');
      ALTER SEQUENCE public.users_id_seq OWNED BY public.users.id;

Database access configuration inside code

Under config/config.go directory in the project, you will find database access configuration. You can change it with your custom configuration.

      DB_USER     = "docker"
      DB_PASSWORD = "docker"
      DB_NAME     = "docker"
      PORT = "32770"

      go version go1.9.2 darwin/amd64

You need to following library for the postgres.
