Pinned Package Updater

Pinned Package Updater (PPU) is a tool for managing pinned packages installed with package managers in a Dockerfile manifest. The goal of this tool is to reduce the administrative burden of keeping packages up to date with upstream security releases by offering an automatic mechanism for checking for new security releases and patching the existing Dockerfile manifest with those new versions.

The integration into the CI/CD is left up to the user, but can be as simple as committing the changes and opening an MR.

Usage

Standalone Usage

The default behavior for the tool is to operate in a standalone mode. In this mode the tool is responsible for parsing the Dockerfile, fetching the upstream package manager resources, identifying the upgrades available, and applying those upgrades. An alternative distributed mode is available to remove the upstream package resource caching and version upgrade determination logic.

pinned-package-updater check
pinned-package-updater update

Distributed Usage

In distributed mode the tool relies on an external deployment of PPU that is running in serve mode pinned-package-updater serve. To cache the upstream package manager resources and handle the upgrade check logic. In this mode much of the work can be cached between requests and the overhead of checking for pinned version updates is significantly reduced.

The tool running in this mode will revert to standalone mode if the upstream service is unavailable.

pinned-package-updater --remote <address of the upstream service> check
pinned-package-updater --remote <address of the upstream service> update

Building

To build pinned-package-updater, run go build
