Hello,
I’m using selenoid and selenoid-ui on my Rocky Linux 9 server, everything looks OK, docker logs of selenoid, selenoid ui, selenoid/chrome container when started but when I create selenoid/chrome session it takes several minutes to display the session UI on selenoid UI
Basically, vnc inside docker container is on the 100% even if I maxed it out with resources, and question is - are there any privileges/firewall configuration/security configuration I should set in order to speed up vnc connecting?
and after that, after 3-5 minutes, session UI is displayed.
While waiting for the VNC connection, I inspected selenoid/chrome container and the CPU usage was on 100% by the x11vnc:
As soon as session UI is displayed, CPU usage drops to the normal (not 100%)
This is the case on Rocky Linux 9 server but not on Ubuntu, tried different selenoid configurations but wasn’t successful…
Configuration I’m using now:
{
"chrome": {
"default": "127.0",
"versions": {
"127.0": {
"image": "selenoid/chrome:127.0",
"port": "4444",
"path": "/",
"tmpfs": {
"/tmp": "size=512m"
},
"env": ["ENABLE_VNC=true", "SCREEN_WIDTH=1920", "SCREEN_HEIGHT=1080", "SCREEN_DEPTH=24"],
"shmSize" : 268435456,
"mem": "512m",
"cpu": "4.0"
}
}
}
}
