I have two containers (Nginx and Busybox) running in different pods in the same namespace. Whenever I try to get a ping or wget from busybox pod to Nginx I am unable to do that and I not able to understand why is this happening as I should be able to communicate from pod to another.
Ngnix Pod Description
apiVersion: v1
kind: Pod
metadata:
creationTimestamp: null
labels:
run: nginx
name: nginx
spec:
containers:
- image: nginx
name: nginx
ports:

resources: {}
dnsPolicy: ClusterFirst
restartPolicy: Never
status: {}BusyBox Pod Description
apiVersion: v1
kind: Pod

creationTimestamp: null
labels:
run: busybox
name: busybox
spec:
containers:
- image: busybox

wget -O- 172.XX.XX.XXX:XX
Connecting to 172.XX.XX.XXX:XX (172.XX.XX.XXX:XX)
wget: can't connect to remote host (172.XX.XX.XXX): Connection timed outOn loging I get this
2019/07/12 18:47:30 [error] 7#0: *1177 "/usr/local/nginx/html/nginx_status/index.html" is not found (2: No such file or directory), client: 127.0.0.1, server: localhost, request: "GET /nginx_status/ HTTP/1.1", host: "localhost"Looks like the 404 error in nginx logs mentioned by you comes from the nginx host as the client says localhost. It has nothing to do with your connection timeout error.
How did you find the cluster IP of the pod? Usually, you can get the ip address with the command:
kubectl get pods -o wideCheck if you are using the correct ip in the wget command.
