One more simple doubt, when someone asks you below -- what should you write node . . .

One more simple doubt, when someone asks you below – what should you write node name or the what?
Question:

Get the list of nodes in JSON format and store it in a file at /opt/outputs/nodes-z3444kd9.json

My answer was, (which is wrong :stuck_out_tongue: )

kubectl get nodes -o=jsonpath='{.items[*].metadata.name}' > /opt/outputs/nodes-z3444kd9.json
#2

Fernando Jimenez:

kubectl get nodes -o json > /opt/outputs/nodes-z3444kd9.json
#3

SaidBen:
I would use this >> kubectl get nodes -o=jsonpath='{.items[*].*metadata.name*}' > /opt/outputs/nodes-z3444kd9.json

#4

Fernando Jimenez:
@SaidBen That’s assuming that what you are being asked is just the name of the nodes. I interpreted the question as it says. “Get the list of nodes …” How do you do that with the kubectl client?

kubectl get nodes

“… in json format …”

kubectl get nodes -o json

“… and store it in a file at /opt/outputs/nodes-z3444kd9.json”. Thus:

kubectl get nodes -o json > /opt/outputs/nodes-z3444kd9.json
