Automatisierung eines Podman-basierten CI-Workflows mit Python ⇐ Linux

[Anonymous]

Ich möchte ein Python3 -Skript schreiben, das ein unberührtes System einstellt (z. B. "Fedora: 42"), einen lokalen Klon eines Git -Repositorys kopieren und seine Tests ausführen. Für kontinuierliche Integration. Ich würde es wirklich vorziehen, Dockerfiles zu vermeiden. Ein ähnlicher Code in Perl ist https://github.com/thewml/website-meta- ... -ci-run.pl. (Beachten Sie, dass es Podman auf Fedora verwendet.) Ich möchte die Python3 -Äquivalente der Methoden unter https://metacpan.org/pod/docker::cli::w ... :Container. Kann jemand helfen? Holen Sie sich .exec_run () zum Arbeiten? Ich möchte in der Lage sein, Bash -Codes im Container auszuführen, ihre Stdout/Stderr anzusehen und darauf zu warten, dass sie fertig sind. Synchron. < /P>
Ich bin auf Fedora 42 x86-64 Podman.
