Hello, Everytime I create multi container pod, I get below error. Can someone please help. I used --dry-run=client -o yaml to generate yaml for pod for single container , then edited for adding 2nd image.
controlplane $ cat multi.yaml
apiVersion: v1
kind: Pod
metadata:
name: multia
spec:
containers:

  • name: nginx
    image: nginx
  • name: redis
    image: redis
    controlplane $ kubectl create -f multi.yaml
    pod/multia created
    controlplane $ kubectl logs multia -f
    error: a container name must be specified for pod multia, choose one of: [nginx redis]
    controlplane $

Samuel Begin:
your pod has 2 containers. you must tell kubectl which container you want to see the logs of.

#3

Samuel Begin:
when your pod has a single container, it only has one to choose from, so it dosent ask you

#4

Samuel Begin:
kubectl logs multia -c nginx -f
or
kubectl logs multia -c redis -f
will yield what you want
