Deploying PgAdmin4 and PostgreSQL with Docker

Setup for Databases and Administration

Docker is a powerful tool that can be used to easily deploy and manage applications in containers. In this article, we will walk you through the steps of installing PostgreSQL and pgAdmin 4 in a Docker environment.

Prerequisites

Before you begin, you will need to have Docker installed on your system. You can download Docker for free from the Docker website.

Step 1: Create a Docker Compose File

The first step is to create a Docker Compose file. This file will define the services that you want to run in your Docker environment. In this case, we will be running PostgreSQL and pgAdmin 4. Here is an example Docker Compose file: ```yaml version: "3.7" services: postgres: image: postgres:14 ports: - "5432:5432" environment: - POSTGRES_USER=postgres - POSTGRES_PASSWORD=mypassword - POSTGRES_DB=mydatabase pgadmin: image: dpage/pgadmin4 ports: - "8080:80" ```

Step 2: Build and Run the Docker Compose File

Once you have created a Docker Compose file, you can build and run the services defined in the file. To do this, run the following command: ```bash docker-compose up -d ``` This command will build and run the PostgreSQL and pgAdmin 4 services.

Step 3: Access PgAdmin4

Once the services are running, you can access pgAdmin 4 by visiting http://localhost:8080 in your web browser. You can log in to pgAdmin 4 using the username and password that you specified in the Docker Compose file.

Conclusion

In this article, we have shown you how to deploy PostgreSQL and pgAdmin 4 in a Docker environment. This is a quick and easy way to get started with these powerful tools.
