Public Postgres Image vs. Minimus Hardened Postgres Image

Postgres Image Overview

The Postgres image is a containerized version of the PostgreSQL database, an open-source relational database management system. It is widely used for handling structured data and supports a variety of use cases such as web applications, data warehousing, and analytics. Known for its strong performance, scalability, and flexibility, the Postgres image is suitable for both small-scale applications and complex enterprise-level deployments.

Minimus Postgres Image

Frequently Asked Questions

Postgres Container Image FAQ

Answers to common questions about Postgres and the Minimus Hardened Postgres Image
What is the default username and password when using the Postgres image?
The default username is typically set to 'postgres'. The password can be configured using the POSTGRES_PASSWORD environment variable when launching the container. If the password isn't explicitly set, some images may refuse to start for security reasons.
How can I persist data in a Postgres container to avoid losing it after container restarts?
To persist data, you can mount a volume or bind a host directory to the container's data directory, usually located at /var/lib/postgresql/data. This ensures data is stored outside of the container's ephemeral storage.
How do I connect to the Postgres server running in a container from my host machine?
You can connect using a PostgreSQL client by specifying the host as 'localhost' (or the appropriate IP), the port (default is 5432), and the correct username and password. Make sure to publish the container's port to the host using the -p flag when starting the container.
Can I replace my Postgres image with the Minimus Hardened Postgres Image?
Yes. The Minimus Postgres image contains everything you need to run Postgres successfully.
Does Minimus offer FIPS 140-3 images?
Yes, Minimus images are hardened to CIS and NIST standards, with FIPS 140-3 and STIG ready variants available.
