Question: How do I install prometheus-podman-exporter for Ubuntu?

[ckhatton-pvfscaffolding]

I have:

• checked out v1.10.1 for Podman v4.
• Built from source.

It runs if I run the binary straight up, but if I setup a systemctl file or run the binary via another user (sudo -u someusername /usr/local/bin/prometheus-podman-exporter --web.listen-address=:9882 --collector.enable-all) it errors.

Could someone help me?

I am having to re-run it on each system boot.

Hi @ckhatton-pvfscaffolding

Have you tried the container image one available under quay.io ?

[ckhatton-pvfscaffolding]

Thank you. I try run it as a Podman container tied to the user that has the containers running to monitor, and I get this error:

❯ podman run --replace -d \
        --name prometheus-podman-exporter \
        -e CONTAINER_HOST=unix:///run/user/$UID/podman/podman.sock \
