Linux Containers have become an incredibly popular method for running software. OliveTin supports every way of running Linux containers - spanning from homelabs up to enterprise environments. As a container, it can be used standalone using Podman/Docker, through to using docker-compose or even on Kubernetes.
However, a lot of OliveTin use cases, such as providing an interface to run scripts, rely on files on their local Linux filesystem - containers, by definition, have their own separate filesystem. It is of course possible to "bind mount" parts of your local filesystem into OliveTin, but sometimes this requires more effort, or introduces subtle problems that are more complicated to solve. If you have a good amount of experience with Linux containers, then this approach is absolutely fine - but if you are new to these types of problems - not seeing files you expect, file permissions errors, etc, then it might just be easier to install using a Linux package instead.
Sometimes you just want to (or have to) use containers, but also want to use these local resources as well. Instead of bind-mounting lots of stuff into the Linux container and creating a really complicated container definition (which is hard to scale), consider a simple alternative: SSH with OliveTin. This allows you to easily SSH back into the container host and keep your container definition really simple. This approach works great and is popular for a lot of users.
You’re new to Linux containers, or not very comfortable with them
Needs to use lots of different file paths on the host filesystem
Needs to control processes, like systemd services
