Neste post, vamos configurar o docker-compose, para disponibilizar o PostgreSQL com PgAdmin, de maneira fácil e rápida.

Premissa: Espera-se que tenha instalado o Docker e Docker-Compose.

docker-compose.yml

version: '3'

services:
  teste-postgres-compose:
    image: postgres
    environment:
      POSTGRES_PASSWORD: "Postgres2021!"
    ports:
      - "15432:5432"
    volumes:
      - /home/fernando/data/postgres:/var/lib/postgresql/data 
    networks:
      - postgres-compose-network
      
  teste-pgadmin-compose:
    image: dpage/pgadmin4
    environment:
      PGADMIN_DEFAULT_EMAIL: "lfchaim@gmail.com"
      PGADMIN_DEFAULT_PASSWORD: "PgAdmin2021!"
    ports:
      - "16543:80"
    depends_on:
      - teste-postgres-compose
    networks:
      - postgres-compose-network

networks: 
  postgres-compose-network:
    driver: bridge

Subindo os conteiners

$ sudo docker-compose up -d

Ao final do processo, deve aparecer o log final

Status: Downloaded newer image for dpage/pgadmin4:latest
Creating postgres_teste-postgres-compose_1 ... done
Creating postgres_teste-pgadmin-compose_1  ... done

Pode-se verificar os conteiners rodando, com o comando

$ sudo docker ps

Deverá aparecer

CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                            NAMES
1fffaaa4887c        dpage/pgadmin4      "/entrypoint.sh"         About a minute ago   Up About a minute   443/tcp, 0.0.0.0:16543->80/tcp   postgres_teste-pgadmin-compose_1
63e1934f7cdb        postgres            "docker-entrypoint.s…"   About a minute ago   Up About a minute   0.0.0.0:15432->5432/tcp          postgres_teste-postgres-compose_1

Agora, vamos acessar o PgAdmin

Abra um navegador e digite: http://localhost:16543

Forneça o usuário e senha informados no docker-compose

Exemplo: lfchaim@gmail.com / PgAdmin2021!

Na tela do PgAdmin, clique em “Add New Server”

Dê um nome: teste-postgres-compose

Repita o nome em Host: teste-postgres-compose

Usuário: postgres

Senha: Postgres2021! (mesma do docker-compose)

Clicar em “Save”

Pronto! Seu ambiente está criado!
