Oracle has a free tier if you just want to experiment. With the 1 AMD CPU / 1GB RAM option you could try the docker solution mentioned by another user. For the quad core 24GB RAM Ampere instance I can recommend this script here, which will take care of the installation and auto updating for you. Looking at the script, there's no reason it shouldn't work on x86 instances also if for some reason you hate docker.
