+# Introduction to PostgreSQL
+
+This is part 1 of my series on learning PostgreSQL. <br/>
+The primary focus is getting PostgreSQL up and running and </br>
+taking a first look at the database. </br>
+
+PostgreSQL [Docker Image](https://hub.docker.com/_/postgres)
+
+## Run a simple PostgreSQL database (docker)
+
+```
+ docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -d postgres
+```
+
+## Run a simple PostgreSQL database (compose)
+
+```
+cd storage/databases/postgresql/1-introduction
+
+docker compose up
+```
+
+We can access our database from the adminer web page on `http://localhost8080` </br>
+
+
+When running containers, its always important to pull the image by tag </br>
+to ensure you always get the same container image, else it will pull latest. </br>
+We will do that in the next step. </br>
+
+## Persisting Data
+
+To persist data to PostgreSQL, we simply mount a docker volume. </br>
+This is the way to persist container data. </br>
+PostgreSQL stores its data by default under `/var/lib/postgresql/data` 
+Also take note we are running a specific version of PostgreSQL now:
+
+```
+docker run -it --rm --name postgres `
+  -e POSTGRES_PASSWORD=admin123 `
+  -v ${PWD}/pgdata:/var/lib/postgresql/data `
+  postgres:15.0
+```
+
+We can enter the container to connect to SQL:
+
+```
+# enter the container
+docker exec -it postgres bash
+
+# login to postgres
+psql -h localhost -U postgres
+
+#create a table
+CREATE TABLE customers (firstname text,lastname text, customer_id serial);
+
+#add record
+INSERT INTO customers (firstname, lastname) VALUES ( 'Bob', 'Smith');
+
+#show table
+\dt
+
+# get records
+SELECT * FROM customers;
+
+# quit 
+\q
+
+```
+
+Now we can see our data persisted by killing and removing the container:
+
+```
+docker rm -f postgres
+```
+
+Run it again with the above `docker run` command and list our record with the above commands we've learnt </br>
+
+## Networking
+
+PostgreSQL by default uses port `5432`. </br>
+Since we are running in Docker, we can bind a different port if we wish with Docker's `-p` flag. </br>
+For example, we can expose port `5000` outside the container :
+
+```
+docker run -it --rm --name postgres `
+  -e POSTGRES_PASSWORD=admin123 `
+  -v ${PWD}/pgdata:/var/lib/postgresql/data `
+  -p 5000:5432 `
+  postgres:15.0
+```
+Note that this does not change the port which PostgreSQL runs on. </br>
+To change that, we need to explore the configuration.
+
+## Configuration 
+
+PostgreSQL can be configured using environment variables as well as a config file. </br>
+
+PostgreSQL has a ton of configuration options. </br>
+In the next chapter, we will explore the configuration of PostgreSQL. </br>
+
+## Docker Compose
+
+Let's update our compose file to reflect our latest changes. </br>
+
+We need to update the docker image, the port we want to expose outside of the container as well as a volume mount for persistence. </br>
+
+```
+version: '3.1'
+services:
+  db:
+    image: postgres:15.0
+    restart: always
+    environment:
+      POSTGRES_PASSWORD: admin123
+    ports:
+    - 5000:5432
+    volumes:
+    - ./pgdata:/var/lib/postgresql/data
+  adminer:
+    image: adminer
+    restart: always
+    ports:
+      - 8080:8080
+```
+
+That's it for chapter one! </br>
+In [chapter 2](../2-configuration/README.md), we will take a look at Configuration and how to start our PostgreSQL instance with a custom configuration file. </br>
+We will also explore the customization options available. </br>
