project metrics (resource quota details)

[dackmail]

is it possible to get project metrics (resource quota information) CPU / memory limits / requests?.
thanks

@dackmail You can use the oc_action() method to essentially call any command that is supported by oc...
There is an example here: oc_action.py
So, something like:

oc.oc_action(oc.cur_context(), "get", cmd_args=["resourcequotas", "-A"])

Should get you all the resourcequotas on the cluster.

... and to get warning events of projects
thanks too

... and to get warning events of projects

To get all the Warning events on the cluster:
oc.oc_action(oc.cur_context(), "get", cmd_args=["events", "-A", "--field-selector", "type==Warning"])

For a specific namespace, you can do either:
oc.oc_action(oc.cur_context(), "get", cmd_args=["events", "-n", "my-project", "--field-selector", "type==Warning"])
OR

with oc.project('my-project'):
     oc.oc_action(oc.cur_context(), "get", cmd_args=["events", "--field-selector", "type==Warning"])

I am new in python :) and have this message on last code:
<openshift.action.Action object at 0x000001C4c24B5640>

What you are seeing there is the address, in memory, of the "Action" object itself. You'll want to do something like this instead:

action = oc.oc_action(oc.cur_context(), "get", cmd_args=["events", "--field-selector", "type==Warning"])
print(action.out)

Personally, I would recommend starting with something like this and improving as necessary...
