Overview: postgres-fips Chainguard Image

Minimal PostgreSQL image.

Download this Image

The image is available on

docker pull


The only mandatory environment variable needed by the PostgreSQL Image is POSTGRES_PASSWORD.

You can test the PostgreSQL Image by running the following command:

docker run --rm -e POSTGRES_PASSWORD=password -ti --name postgres-test

This command will run the Image, but no data within the PostgreSQL database will persist after the Image stops running.

To persist PostgreSQL data you can mount a volume mapped to the data folder:

docker run --rm -v $PWD/data:/var/lib/postgresql/data -e POSTGRES_PASSWORD=password -ti --name postgres-test

In a new terminal, exec into the running container:

docker exec -ti postgres-test bash

Connect using the postgres user:

su postgres

Use the createdb wrapper to create a test database:

createdb test

Then use the PostgreSQL client to Connect to the new database:

psql test

From there you can interact with the database as you would with any other PostgreSQL database. For instance, you can create a sample table:

CREATE TABLE accounts (
	user_id serial PRIMARY KEY,
	username VARCHAR ( 50 ) UNIQUE NOT NULL,
	password VARCHAR ( 50 ) NOT NULL,
	last_login TIMESTAMP

You could then insert data into the table:

INSERT INTO accounts (username, password, email, created_on, last_login)

You can also use all of PostgreSQL’s internal meta-commands. For example, \dt will list all the tables stored within the database:

          List of relations
 Schema |   Name   | Type  |  Owner
 public | accounts | table | postgres
(1 row)

This getting started guide outlines how to set up and run a PHP application that stores its data in a PostgreSQL database running within a containerized environment.
