Lab 5.1 unable to finish - kubernetes-admin no longer access to api ?

curl --cert client.pem --key client-key.pem --cacert ca.pem https://10.142.0.2:6443/api/v1/pods
work well.
But:
curl --cert client.pem --key client-key.pem --cacert ca.pem -XPOST -H 'Content-Type: application/json' [email protected] https://10.142.0.2:6443/api/v1/pods
give this output:
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {
},
"status": "Failure",
"message": "the server does not allow this method on the requested resource",
"reason": "MethodNotAllowed",
"details": {
},
"code": 405

I was able to finish lab 5.1 just now, mostly as written. In my case, the one exception was that since I'm using minikube on Linux, I just directly used the cert/key files as shown below:
$ curl --cert .minikube/client.crt --key .minikube/client.key --cacert .minikube/ca.crt https://192.168.99.100:8443/api/v1/namespaces/default/pods -XPOST -H'Content-Type: application/json' [email protected] { "kind": "Pod", "apiVersion": "v1", "metadata": { "name": "curlpod", "namespace": "default", "selfLink": "/api/v1/namespaces/default/pods/curlpod", "uid": "56353669-0c7e-11e9-8a4e-080027d81532", "resourceVersion": "19159", "creationTimestamp": "2018-12-30T22:00:36Z", "labels": { "name": "examplepod" } }, "spec": { "volumes": [ { "name": "default-token-wc2fg", "secret": { "secretName": "default-token-wc2fg", "defaultMode": 420 } } ], "containers": [ { "name": "nginx", "image": "nginx", "ports": [ { "containerPort": 80, "protocol": "TCP" } ], "resources": { }, "volumeMounts": [ { "name": "default-token-wc2fg", "readOnly": true, "mountPath": "/var/run/secrets/kubernetes.io/serviceaccount" } ], "terminationMessagePath": "/dev/termination-log", "terminationMessagePolicy": "File", "imagePullPolicy": "Always" } ], "restartPolicy": "Always", "terminationGracePeriodSeconds": 30, "dnsPolicy": "ClusterFirst", "serviceAccountName": "default", "serviceAccount": "default", "securityContext": { }, "schedulerName": "default-scheduler", "tolerations": [ { "key": "node.kubernetes.io/not-ready", "operator": "Exists", "effect": "NoExecute", "tolerationSeconds": 300 }, { "key": "node.kubernetes.io/unreachable", "operator": "Exists", "effect": "NoExecute", "tolerationSeconds": 300 } ], "priority": 0 }, "status": { "phase": "Pending", "qosClass": "BestEffort" } }
Here you can see that the pod was created:
$ kubectl get pods NAME READY STATUS RESTARTS AGE curlpod 1/1 Running 0 2m51s

Hi @traq ,
If step 7 worked ok for you, on step 9 did you attempt to curl to "https://10.142.0.2:6443/api/v1/namespaces/default/pods"?
That's the URL used in step 9 in the Lab manual, and it is different than the URL from step 7.
In step 7 you are just making an inquiry to the API server, to verify that you can connect via the ca, cert and key files.
In step 9 you are creating a pod, and that resource will be created and saved under ".../api/v1/namespaces/default/pods" directory.

This:
url --cert ./client.pem --key ./client-key.pem --cacert ./ca.pem -XPOST -H 'Content-Type: application/json' [email protected] https://10.142.0.2:6443/api/v1/namespaces/default/pods
work well, and
kubectl get pod
NAME READY STATUS RESTARTS AGE
busybox 0/1 Completed 0 3d22h
curlpod 1/1 Running 0 3sSo it's good be update Lab 5.1, because:
curl --cert ./client.pem --key ./client-key.pem --cacert ./ca.pem -XPOST -H 'Content-Type: application/json' [email protected] https://10.142.0.2:6443/api/v1/pods
not working any more0 -
@traq
That is the URL in Lab 5.1 step 9.
If the URL from step 7 (.../api/v1/pods) is used with the curl command in step 9, it will not work. So in order to get a successful output in step 9, the URL has to be used as it is provided in the Lab 5.1 in step 9 (.../api/v1/namespaces/default/pods).
