| kata-irc-bot | <longkb> Hi everyone, I am new in Kata containers :slightly_smiling_face: Could you help me to figure out where should I deploy Kata on? VMs or Bare Metal? | 07:16 |
|---|---|---|
| kata-irc-bot | <johnnyjacob> @longkb I found this guide helpful to start of - https://github.com/kata-containers/documentation/blob/master/install/docker/ubuntu-docker-install.md | 07:36 |
| kata-irc-bot | <longkb> @johnnyjacob Yeah. Thanks for your guide. Actually, I am studying Kata for Multi-tenancy concept. And we have two option for Kata deployments. So I wonder where should we deploy Kata on for better performance | 07:40 |

| kata-irc-bot | <caoruidong> Bare Metal offers better performance | 09:06 |

| kata-irc-bot | <longkb> Thanks @caoruidong. I think so | 10:03 |

| kata-irc-bot | <razvan.rosca> Hey. I just (re)discovered Kata and it sounds very interesting! Supposing that I don't need Pods, only CTs (docker or kube), can I: 1) limit the vCPU numbers per CT? 2) limit the amount of RAM allocated per CT? 3) limit the IO speed per CT? 4) create internal networks between CTs? | 21:56 |
| kata-irc-bot | <razvan.rosca> Basically I want to know if Kata can be used as an alternative to OpenVZ or LXC. | 21:59 |
| kata-irc-bot | <eric.ernst> WHen you say CT, you mean containers, right ? :slightly_smiling_face: | 22:17 |
| kata-irc-bot | <eric.ernst> cgroups allow you to throttle IO, though TBH I haven't personally experimented with this. | 22:18 |
| kata-irc-bot | <eric.ernst> The rest I use every day with Kata. | 22:18 |
| kata-irc-bot | <eric.ernst> You can do this easily with docker, if you want to test it out. | 22:19 |

| kata-irc-bot | <raravena80> yes cgroups will allow you to throttle the CPU: `--cpu-shares=0`, `--cpu-period`,` --cpu-quota` in Docker. CPU Request and Limit in a pod in k8s. Keep in mind that, you have to make sure that your VM in Kata has enough resources for whatever you are trying to accomplish. | 23:37 |
