[Discuss] Specifying CPU and Memory in Docker Cartridges
Hi Devs,
I have now implemented support to specify CPU (number of cores) and Memory
(in MB) in Docker Cartridges. These values will be passed to Kubernetes
when creating a Pod and Kubernetes will limit those resources to containers
accordingly.
If CPU and Memory should not be restricted, above parameter values can be
set to zero. Please find a sample cartridge definition below:
{
"type": "php",
"provider": "apache",
"category": "framework",
"host": "php.stratos.org",
"displayName": "php",
"description": "php Cartridge",
"version": "7",
"multiTenant": "false",
"loadBalancingIPType": "public",
"portMapping": [
{
"protocol": "http",
"port": "80",
"proxyPort": "8281"
}
],
"deployment": {
"baseDir": "/var/www"
},
"iaasProvider": [
{
"type": "kubernetes",
"imageId": "stratos/php:4.1.0-beta",
"networkInterfaces": [
],
"property": [
]
}
],
"property": [
{
"name": "KUBERNETES_CONTAINER_CPU",
"value": "1"
},
{
"name": "KUBERNETES_CONTAINER_MEMORY",
"value": "512"
}
]
}
Thanks

Thanks for the feedback Raj! I think you made a good point, the defaults
should be set to zero to make them none restricted.
What I observed is that when we set these values the containers get more
time to start.
Thanks

I went through the code and figured it out :-)
If we don't specify these parameters, the default values will be cpu -> 1
and ram-> 1024. I guess that should be the way to do it.
Thanks.

This is great Imesh!
If we don't specify these parameters, the CPU and Memory won't be
restricted right? Do we have to explicitly set these to 0?
Thanks.
