Yes it is. The problem is that you can get a 250+ MiB container just to deliver a couple hundred KiB of python and a systemd unit. What I propose in bullet point 4 below could still be a system container, it just squats on the hosts software. Whether or not this is "good practice" or not is up for debate. >> * have some small agents that need to run as a daemon on the host >> some solutions: >> ^ build own ostree - more maintenance >> ^ package layer - requires reboot >> ^ run in container - large containers for small agents >> ^ run as container that acutally bind mounts in host directories >> ` very small container with just the agent >> ` when container runs it bind mounts in software from the >> host. i.e. using the hosts python stack.
