Hello,
I only have a server with 4 Core, 8GB RAM and 240GB SSD. Is it still possible to run Zammad with Elasticsearch or do I feel significant restrictions, when I not have the recommended RAM size of 10GB? Can I then not use Zammad properly and everything hangs?
In the first months there will be not so much traffic. Maybe 5-25 tickets a week.
Thank you for your help…
Hello Kulane,
this is possible but you have to limit elasticsearch not to fit more ram like
(your ram)/2 - 0,5GB (in your env.). Otherwise the OOM could become active.
You’re welcome!
Okay, I will do this. Thanks!
And there is no disadvantage if elasticsearch has less RAM than recommended? What can theoretically happen?
None at all. Maybe slighty slower reponse if you’re using rusty storage.
No Zammad instance really needs 50% of it’s memory allocated to Elasticsearch.
All right, thank you so much. I will be the only user in the first months and there will be just a few tickets. Maybe some days or weeks no tickets. Then it should be fine
Can’t wait to try Zammad! Thank you all.
Edit: And do you recommend to install Zammad with docker or manual with package manager? For me both its fine… but I am not the best linux admin, so maybe docker would be better? Are there any disadvantages if I use docker instead of installing it manually?
No. You can use docker or package-install. In docker maybe there is a little bit more ressource-consumption, cause of the docker-overhead, but this is mostly marginal.
