Configuring Azure log analytics - azure

Question

I am following this documentation https://learn.microsoft.com/en-us/azure/aks/tutorial-kubernetes-monitor to configure a monitoring solution on AKS with the following yaml file
apiVersion: extensions/v1beta1
kind: DaemonSet
metadata:
name: omsagent
spec:
template:
metadata:
labels:
app: omsagent
agentVersion: 1.4.0-12
dockerProviderVersion: 10.0.0-25
spec:
containers:
- name: omsagent
image: "microsoft/oms"
imagePullPolicy: Always
env:
- name: WSID
value: <WSID>
- name: KEY
value: <KEY>
securityContext:
privileged: true
ports:
- containerPort: 25225
protocol: TCP
- containerPort: 25224
protocol: UDP
volumeMounts:
- mountPath: /var/run/docker.sock
name: docker-sock
- mountPath: /var/opt/microsoft/omsagent/state/containerhostname
name: container-hostname
- mountPath: /var/log
name: host-log
- mountPath: /var/lib/docker/containers/
name: container-log
livenessProbe:
exec:
command:
- /bin/bash
- -c
- ps -ef | grep omsagent | grep -v "grep"
initialDelaySeconds: 60
periodSeconds: 60
nodeSelector:
beta.kubernetes.io/os: linux
# Tolerate a NoSchedule taint on master that ACS Engine sets.
tolerations:
- key: "node-role.kubernetes.io/master"
operator: "Equal"
value: "true"
effect: "NoSchedule"
volumes:
- name: docker-sock
hostPath:
path: /var/run/docker.sock
- name: container-hostname
hostPath:
path: /etc/hostname
- name: host-log
hostPath:
path: /var/log
- name: container-log
hostPath:
path: /var/lib/docker/containers/
This fails with an error
error: error converting YAML to JSON: yaml: line 65: mapping values are not allowed in this context
I've verified that the file is syntactically correct using a yaml validator, no sure whats wrong?
This is kubernetes version 1.7
This also happens with version 1.9

Answer 1

That yaml file works for me:
[root#jasoncli#jasonye aksoms]# vi oms-daemonset.yaml
[root#jasoncli#jasonye aksoms]# kubectl create -f oms-daemonset.yaml
daemonset "omsagent" created
[root#jasoncli#jasonye aksoms]# kubectl get daemonset
NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE
omsagent 1 1 0 1 0 beta.kubernetes.io/os=linux 1m
Please check your kubectl client version with this command kubectl version, here is my output:
[root#jasoncli#jasonye aksoms]# kubectl version
Client Version: version.Info{Major:"1", Minor:"8", GitVersion:"v1.8.5", GitCommit:"cce11c6a185279d037023e02ac5249e14daa22bf", GitTreeState:"clean", BuildDate:"2017-12-07T16:16:03Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"7", GitVersion:"v1.7.7", GitCommit:"8e1552342355496b62754e61ad5f802a0f3f1fa7", GitTreeState:"clean", BuildDate:"2017-09-28T23:56:03Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}
You can run the following command az aks install-cli to install kubectl client locally.
