I'm experimenting with Podman on a Ubuntu 22.04 Vagrant box. I installed Podman and
its dependencies manually from GitHub releases rather than using the outdated version in
the Ubuntu repositories. This means I had to rely on web sources for my configuration
files, and I may have gotten something a bit wrong.
Here's the systemd service file:
[Unit]
Description=TileServer GL
After=network-online.target
Requires=network-online.target
[Service]
Restart=always
ExecStartPre=/usr/bin/podman pull maptiler/tileserver-gl:v3.1.1
ExecStart=/usr/bin/podman container run --rm \
--name tileserver -u www-data -p 8083:8080 \
-v /vagrant_data/resources/tiles:/data \
maptiler/tileserver-gl:v3.1.1 \
-c /etc/tileserver.json \
--public_url https://devserver.local/tiles
[Install]
WantedBy=default.target
/etc/containers/containers.conf:
[containers]
log_driver="journald"
tz="local"
[network]
network_backend="netavark"
registries.conf and policy.json are minimal and have nothing related to this issue.
When I run the service and do `journalctl -u tileserver`, this is what gets logged after
the container has been pulled and started:

So, everything that tileserver prints to stdout, podman repeats. If I run the container as
a simple terminal command outside systemd, everything is only printed out once.
Any ideas for a fix? I don't particularly care whether it's the
'tileserver' or 'podman' rows out of the duplicated ones that end up in
the logs, but I'd rather not have both logged.
