openGauss, an enterprise relational database with PostgreSQL heritage, run as a single node you control.
openGauss is an enterprise grade open source relational database built on PostgreSQL foundations and hardened for demanding transactional workloads. It gives you standard SQL, ACID transactions, multi version concurrency control and the mature relational model teams already know, in a database designed for reliability and consistent performance under load.
This image runs the standalone single node configuration, so the database accepts connections shortly after the instance boots with nothing to assemble. It suits teams who want a capable PostgreSQL heritage engine on infrastructure they control, developers who need a familiar relational database for an application backend, and anyone evaluating openGauss for enterprise workloads without standing up a cluster.
cloudimg delivers openGauss fully installed from the official upstream release as a standalone single node engine, so it is ready to serve connections shortly after first boot. The image is secure by default: upstream seeds two built in superuser accounts, and rather than change them after the fact this image bootstraps the database with a password generated uniquely on each instance's first boot, so no fixed default credential ever exists on your instance, and first boot refuses to complete if any built in account still accepts a weak password. Each superuser receives its own distinct per instance secret, credentials are written to a root only file, and the database port is closed at the network layer by default. Database storage sits on a dedicated disk separate from the operating system, the base is fully patched with unattended security upgrades enabled, and every deployment is paired with a step by step deploy guide and backed by 24/7 cloudimg support.
