# Postgres + PgAdmin

### **Optional**:
- If you want to remove all containers before starting, run the following command:
```shell
docker system prune -a
```

### Create a network 
In my case, I named as ***web-network*** 
```shell
docker network create --driver bridge web-network
```

### Install PostgreSQL
Run the following command to download and install Postgres with the most recent version.
In my case, I named the Postgres image as ***web-postgres***. You also may change the default user and password.
```shell
docker run --name web-postgres --network=web-network -p 5432:5432 -e POSTGRES_PASSWORD=root -e POSTGRES_USER=root -d postgres
```

### Install PgAdmin
Before running the following command, you can make several changes, such as:
- *Image name:* web-pgadmin
- *External port:* 8887
- *Default email:* email@email.com
- *Default password:* root
- *Network name:* web-network
```shell
docker run --name web-pgadmin --network=web-network -p 8887:80 -e PGADMIN_DEFAULT_EMAIL=email@email.com -e PGADMIN_DEFAULT_PASSWORD=root -d dpage/pgadmin4
```

After the installation process, you can access PgAdmin application through your browser with the 
url: ***http://localhost:8887*** or another port that you configured in the previous steps.

While you are registering the database settings, make sure to add in the field *Connection - Host name/address* 
the same name of your Postgres container. In my case, ***web-postgres***.
