Chainguard Container for postgres-fips

Advanced object-relational database management system

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/postgres-fips:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Usage

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 cgr.dev/chainguard/postgres-fips:<version>

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 cgr.dev/chainguard/postgres-fips:<version>

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,
	email VARCHAR ( 255 ) UNIQUE NOT NULL,
	created_on TIMESTAMP NOT NULL,
	last_login TIMESTAMP
);

You could then insert data into the table:

INSERT INTO accounts (username, password, email, created_on, last_login)
VALUES (
'Inky',
'p@$$w0rD',
'inky@example.com',
'2017-07-23',
'2017-07-23'
);

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

\dt

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

Please refer to our guide on getting started with the PostgreSQL Chainguard Image for an in-depth walk-through of how you can use the PostgreSQL Image in practice. 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.

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
