Dockerfile for the excellent nvchecker Python module.
This container works with dfupdate to check itself for updates every week, and new versions are built and pushed automatically.
This container is compliant with the official image specification and runs nvchecker as it's default entrypoint. To have nvchecker run against a project with an toml file in the current working directory, you can run:
docker run -it --rm --mount type=bind,source=${PWD},target=/data/ -w /data snw35/nvchecker:latest nvchecker -c nvchecker.toml
Where nvchecker.toml is the name of the nvchecker configuration file. The nvchecker documentation at https://nvchecker.readthedocs.io shows how to write an nvchecker.toml file for your application.
I use this as part of a workflow to automatically update my container images. It runs in tandem with dfupdate (Dockerfile Updater) to automatically detect when new versions of software packaged in a Dockerfile are available, and to write and commit the changes directly, triggering a new build and container push to Dockerhub. The base image is also updated automatically.
So yes, this nvchecker image updates itself :)
