Do you know of a software which keeps idle some services on a server and only launch them when someone does a request to it?
I would like to host some services which can be accessed at some rare cases, but I would like to avoid them to use the server's resources when it is not needed.
Something which may feel like Heroku's free plan with its server idle, but with software.
@KillianKemps xinetd and systemd sockets come to mind. Is something like that that you are looking for? These days you could probably spin up a docker container to handle a request. And put a path based reverse proxy in front of you want to serve everything from the same domain.
@rmsilva Thank you for your answer, it seems to be what I was looking for! By searching with your keywords I could find this article from Atlassian which gave me even more information: https://developer.atlassian.com/blog/2015/03/docker-systemd-socket-activation/
I will see what I can do with this.
@KillianKemps @rmsilva Glad I could help, thanks for the pointer to the article. I might try that myself :-)
