PostgreSQL 10 and pgAdmin4 with Crunchy Data

Docker Compose configuration to setup an instance of PostgreSQL 10 and a PgAdmin4 web interface. This is based on the next web post by Crunchy Data: https://info.crunchydata.com/blog/easy-postgresql-10-and-pgadmin-4-setup-with-docker. Personally, I didn't like the manual execution of steps described. So, I am working in a more automated procedure to use the tools.

Settings

It's highly suggested that you change the default login values in the next files pg.env and pgadmin.env.

Which details are specified in those files? They are storing environment variables that are used while Docker is creating the containers. Please refer to:

File: pg.env

Setting Meaning
PG_MODE A parameter just for crunchy-postgres that determines how to setup this PostgreSQL instance. Other options include "replica" for creating a read-only instance, as well as "set" for creating a StatefulSet in a Kubernetes cluster
PG_PRIMARY_USER Sets the username of the superuser for your database instance.
PG_PRIMARY_PASSWORD The password for the PG_PRIMARY_USER in your database instance.
PG_DATABASE The name of the default database to create in the database instance.
PG_USER The username of the default user in the database instance. This user will have access to PG_DATABASE
PG_PASSWORD The password for PG_USER
PG_ROOT_PASSWORD The password for the "postgres" user in your database instance, which is the root user.
PG_PRIMARY_PORT The database port that PostgreSQL will run on. The default PostgreSQL port is 5432.

File: pgadmin.env

Setting Meaning
PGADMIN_SETUP_EMAIL The email address used to log into pgAdmin 4
PGADMIN_SETUP_PASSWORD The password used to log into pgAdmin 4
SERVER_PORT The port to run pgAdmin 4 on.

Usage

After configution, execute:

Linux/OSX:

$ cd crunchypg_with_pg4admin
$ docker-compose up -d

Windows:

To be defined.

First configuration:

  • After setup, go to http://localhost:5050/ and login with your established credentials for pgAdmin4.
  • Once logged, select "Object" menu, then hover "Create" and "Server..."
  • A pop-up window will appear. For the "General" tab write a meaningful name.
  • Select "Connection" tab and only write postgres for hostname/address
  • Write your credentials specified in pg.env file
  • Someday, this will be solved or automated. Track the issue at issues
