zabbix-kubernetes-monitoring is zabbix-agent script and template for zabbix server. It is used for Kubernetes monitoring by Zabbix. Easy to deploy and configure. Auto discovery of pods, deployments, services, etc.

1. Copy zabbix_check_kubernetes to /usr/lib/zabbix/externalscripts and k8s-stats.json to /etc/zabbix/ and fix file permissions

cp zabbix_check_kubernetes /usr/lib/zabbix/externalscripts/
cp k8s-stats.json /etc/zabbix/
chmod +x /usr/lib/zabbix/externalscripts/zabbix_check_kubernetes
chown zabbix. /etc/zabbix/k8s-stats.json
chmod 640 /etc/zabbix/k8s-stats.json

2. Import Zabbix template k8s-zabbix-template.xml to Zabbix server
3. Create zabbix user in Kubernetes (can use zabbix-user-example.yml) and set it's token and API server url in k8s-stats.json. The root item key names in JSON config refer to
4. Apply template to host {$K8S_CLUSTER_NAME} macro value in zabbix configuration, see step 5.
5. Update {$K8S_CLUSTER_NAME} macro value appropriately in host configuration. Example:

{
    "my-cloud-123": {
        "api_url": "https://my_cloud_address:6443",
        "access_token": "my_cloud_token"
    }
}

You then need to use {$K8S_CLUSTER_NAME} => my-cloud-123 on zabbix host you have attached the template to

Simply add more dicts to k8s_stats.json. Sample config file provided in repo has two clusters added.

$ kubectl apply -n kube-system -f zabbix-user-example.yml 
serviceaccount/zabbix-user created
clusterrole.rbac.authorization.k8s.io/zabbix-user created
clusterrolebinding.rbac.authorization.k8s.io/zabbix-user created

1. TOKEN:

$ TOKENNAME=$(kubectl get sa/zabbix-user -n kube-system -o jsonpath='{.secrets[0].name}')
$ TOKEN=$(kubectl -n kube-system get secret $TOKENNAME -o jsonpath='{.data.token}'| base64 --decode)
$ echo $TOKEN

2. API SERVER:

$ APISERVER=https://$(kubectl -n default get endpoints kubernetes --no-headers | awk '{ print $2 }')
$ echo $APISERVER
