AWS Elastic Kubernetes Service

Firstly Make sure you have the aws cli, eksctl & kubectl installed on local machine using the following guide

Also make sure you have setup aws configure with your AWS credentials.

To do this run run the following command in your aws terminal.

aws configure

When you type this command, the AWS CLI prompts you for four pieces of information: access key, secret access key, AWS Region, and output format. This information is stored in a profile named default. This profile is used when you run commands, unless you specify another one.

Update your config by running the following command. Replace <enter_region> and <enter_name> with your AWS cluster region and name.

aws eks --region <enter_region> update-kubeconfig --name <enter_name>

Check you can connect to your cluster by running the following command:

kubectl get svc

You will need an instance of kube-state-metrics running on your cluster before you install metricbeat.

Cloning the kube-state-metrics repository locally and applying the example is the easiest way to generate some metrics. You can tailor these to your needs at a later stage.

git clone https://github.com/kubernetes/kube-state-metrics.git

Change into the newly downloaded directory:

cd go/src/k8s.io/kube-state-metrics/

Then to deploy this project, you can simply run:

kubectl apply -f examples/standard

Metricbeat requires kube-state-metrics to be deployed and running to gather the cluster metrics. You can read more about kube state metrics on Github

You're going to need the metricbeat deployment manifest.

curl -L -O cdn.logit.io/metricbeat-kubernetes-7.10.0.yaml

Now you have the manifest we need to add your Stack Logstash endpoint details. Open the file in the terminal editor using the vim or nano command. Alternatively you can choose Open Editor from the console toolbar to make your changes.

vi metricbeat-kubernetes-7.10.0.yaml

or

nano metricbeat-kubernetes-7.10.0.yaml

Update the following lines in the yaml with your Stack Logstash endpoint and Beats-SSL port.

Note: The code snippet occurs two times in the yaml file and needs updating in both.

env:
- name: LOGSTASH_HOST
  value: "guid-ls.logit.io"
- name: BEATS_PORT
  value: "00000"

After updating the code should look as below.

env:
- name: LOGSTASH_HOST
  value: ["your-logstash-host"]
- name: BEATS_PORT
  value: ["your-ssl-port"]

Exit and save the file.

Now we're going to apply the file to the cluster.

kubectl apply -f metricbeat-kubernetes-7.10.0.yaml

If you need to apply further updates after running the apply command you may need to remove the yaml file, make your changes and then apply again.

Confirm your pod has deployed, you should see output similar to that below.

kubectl get po -A

or

kubectl logs ["podname"] --namespace=kube-system

Browse to Kibana and you should see Metrics arriving in your Stack.

Now you should view your data:

If you don't see logs take a look at How to diagnose no data in Stack below for how to diagnose common issues.

If you don't see data appearing in your Stack after following the steps, visit the Help Centre guide for steps to diagnose no data appearing in your Stack or Chat to support now.
