Overview
Helm is a package manager for Kubernetes. Helm 3.x is compatible with Kubernetes versions n-3 where n is the Kubernetes version against which the Helm version has been compiled, while the Helm 2.x manager is only compatible with Kubernetes versions n-1.
LAB #1 - Working with Helm
Go to your Gateway VM. Start by checking the status of Minikube:
trainee@gateway:~$ minikube status minikube type: Control Plane host: Running kubelet: Running apiserver: Running kubeconfig: Configured
1.1 - Installing Helm
Install helm :
trainee@gateway:~$ su -
Password:
root@gateway:~# curl https://baltocdn.com/helm/signing.asc | gpg --dearmor | sudo tee /usr/share/keyrings/helm.gpg > /dev/null
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 1699 100 1699 0 0 17161 0 --:--:-- --:--:-- --:--:-- 17336
root@gateway:~# echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/helm.gpg] https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list
deb [arch=amd64 signed-by=/usr/share/keyrings/helm.gpg] https://baltocdn.com/helm/stable/debian/ all main
root@gateway:~# apt-get update
...
root@gateway:~# apt-get install helm
...
Then check the location of the binary and its version:
root@gateway:~# which helm
/usr/sbin/helm
root@gateway:~# helm version
version.BuildInfo{Version:“v3.16.3”, GitCommit:“cfd07493f46efc9debd9cc1b02a0961186df7fdf”, GitTreeState:“clean”, GoVersion:“go1.22.7”}
To enable command-line auto-completion with the helm command, similar to that under bash, run the following command as trainee:
root@gateway:~# exit logout trainee@gateway:~$ trainee@gateway:~$ source <(helm completion bash)
To view the environment variables for the helm command, run the helm env command:
trainee@gateway:~$ helm env HELM_BIN="helm HELM_BURST_LIMIT="100” HELM_CACHE_HOME="/home/trainee/.cache/helm” HELM_CONFIG_HOME="/home/trainee/.config/helm” HELM_DATA_HOME="/home/trainee/.local/share/helm” HELM_DEBUG="false” HELM_KUBEAPISERVER="” HELM_KUBEASGROUPS="” HELM_KUBEASUSER="” HELM_KUBECAFILE="” HELM_KUBECONTEXT="” HELM_KUBEINSECURE_SKIP_TLS_VERIFY="false” HELM_KUBETLS_SERVER_NAME="” HELM_KUBETOKEN="” HELM_MAX_HISTORY="10” HELM_NAMESPACE="default” HELM_PLUGINS="/home/trainee/.local/share/helm/plugins” HELM_QPS="0.00” HELM_REGISTRY_CONFIG="/home/trainee/.config/helm/registry/config.json” HELM_REPOSITORY_CACHE="/home/trainee/.cache/helm/repository” HELM_REPOSITORY_CONFIG="/home/trainee/.config/helm/repositories.yaml”
Important: Note that the value of the $HELM_NAMESPACE variable is default. To change the namespace used when using the helm command, you can either modify the value of this variable, or use the –namespace or -n option each time you run the command.
To view the kubectl command environment, run the kubectl config view command:
trainee@gateway:~$ kubectl config view

Powerful yet simple, everyone from students to global corporations use it to build beautiful, functional websites. [Overview of WordPress](http://www.wordpress.org) ## TL;DR console helm install my-release oci://registry-1.docker.io/bitnamicharts/wordpress ``` Looking to use WordPress in production? Try [VMware Tanzu Application Catalog](https://bitnami.com/enterprise), the commercial edition of the Bitnami catalog. ## Introduction This chart bootstraps a [WordPress](https://github.com/bitnami/containers/tree/main/bitnami/wordpress) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manag er. It also packages the [Bitnami MariaDB chart](https://github.com/bitnami/charts/tree/main/bitnami/mariadb) which is required for bootstrapping a MariaDB deployment for the database requirements of the WordPress application, and the [Bitnami Memcached chart](https://github.com/bitnami/charts/tree/main/bitnami/memcached) that can be used to cache database queries. Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters. ## Prerequisites - Kubernetes 1.23+ - Helm 3.8.0+ - PV provisioner support in the underlying infrastructure - ReadWriteMany volumes for deployment scaling ## Installing the Chart To install the chart with the release name `my-release`: ```console helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/wordpress ``` > Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_ NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`. The command deploys WordPress on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation. **Tip**: List all releases using `helm list` ## Configuration and installation details ### Resource requests and limits Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for produc tion workloads and these should be adapted to your specific use case. To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](h ttps://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcesPreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/). --More--

To connect to WordPress, follow the instructions in the NOTES section printed on the screen when running the helm install command:
trainee@gateway:~$ export NODE_PORT=$(kubectl get --namespace doe309 -o jsonpath=“{.spec.ports[0].nodePort}” services wordpress)
trainee@gateway:~$ export NODE_IP=$(kubectl get nodes --namespace doe309 -o jsonpath=“{.items[0].status.addresses[0].address}”)
trainee@gateway:~$ echo “WordPress URL: http://$NODE_IP:$NODE_PORT/”
WordPress URL: http://192.168.59.100:32236/
trainee@gateway:~$ echo “WordPress Admin URL: http://$NODE_IP:$NODE_PORT/admin”
WordPress Admin URL: http://192.168.59.100:32236/admin
If you forget the password for the WordPress installation administration interface, use the following command:
trainee@gateway:~$ echo Password: $(kubectl get secret --namespace doe309 wordpress -o jsonpath=“{.data.wordpress-password}” | base64 -d)
Password: my-pass
1.10 - The helm upgrade Command
Updating a Chart is done by modifying the values in the YAML file. In our case, the file is called wordpress-values.yaml. Modify this file to increase the number of Replicas to 2 and to decrease the processor's memory and millicores from their default values of 512Mi and 300m respectively:
To do: Copy the content from here and paste it into your file.
trainee@gateway:~$ vi wordpress-values.yaml
trainee@gateway:~$ cat wordpress-values.yaml
wordpressUsername: helm-user
wordpressPassword: my-pass
wordpressEmail: helm-user@ittraining.loc
wordpressFirstName: Helm
wordpressLastName: User
wordpressBlogName: Learn Helm!
service:
type: NodePort
replicaCount: 2
resources:
requests:
memory: 256Mi
cpu: 100m
Now use the helm upgrade command to update the :
trainee@gateway:~$ helm upgrade wordpress bitnami/wordpress --values wordpress-values.yaml -n doe309 --version 24.1.5
Release "wordpress" has been upgraded. Happy Helming!

1.12 - The helm rollback Command
To return to a previous revision, use the helm rollback command:
trainee@gateway:~$ helm rollback wordpress 3 -n doe309 Rollback was a success! Happy Helming!
Next, check that the current values are those of the targeted revision:
trainee@gateway:~$ helm get values wordpress -n doe309
USER-SUPPLIED VALUES:

service:
type: NodePort
wordpressBlogName: Learn Helm!
wordpressEmail: helm-user@ittraining.loc
wordpressFirstName: Helm
wordpressLastName: User
wordpressPassword: my-pass
wordpressUsername: helm-user
The rollback is clearly indicated in the output of the helm history command:
trainee@gateway:~$ helm history wordpress -n doe309 REVISION UPDATED STATUS CHART APP VERSION DESCRIPTION 1 Fri Dec 20 15:14:17 2024 superseded wordpress-24.1.5 6.7.1 Install complete 2 Fri Dec 20 15:33:45 2024 superseded wordpress-24.1.5 6.7.1 Upgrade complete 3 Fri Dec 20 15:44:46 2024 superseded wordpress-24.1.5 6.7.1 Upgrade complete 4 Fri Dec 20 15:57:01 2024 superseded wordpress-24.1.5 6.7.1 Upgrade complete 5 Fri Dec 20 16:09:02 2024 deployed wordpress-24.1.5 6.7.1 Rollback to 3
1.13 - The helm uninstall Command
Uninstall a Chart using the helm uninstall command. By default, this command also deletes the revision history unless the –keep-history option is specified on the command line. So delete the wordpress Chart as well as the revision history:
trainee@gateway:~$ helm uninstall wordpress -n doe309 release “wordpress” uninstalled
The helm list command demonstrates this deletion:
trainee@gateway:~$ helm list -n doe309 NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
as well as the output of the kubectl get deployments command:
trainee@gateway:~$ kubectl get deployments -l app=wordpress -n doe309 No resources found in doe309 namespace.
However, the helm unistall command does not delete the PersistentVolumeClaim created when the Chart was installed:
trainee@gateway:~$ kubectl get pvc -n doe309 NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS VOLUMEATTRIBUTESCLASS AGE data-wordpress-mariadb-0 Bound pvc-71bba44c-9af2-44c9-9e59-103efdf1b29b 8Gi RWO standard <unset> 56m
To delete the PersistentVolumeClaim, use the kubectl delete pvc command with the –field-selector option:
trainee@gateway:~$ kubectl delete pvc --field-selector metadata.name=data-wordpress-mariadb-0 -n doe309 persistentvolumeclaim “data-wordpress-mariadb-0” deleted
This deletes the PersistentVolumeClaim:
trainee@gateway:~$ kubectl get pvc -n doe309 No resources found in doe309 namespace
LAB #2 - Monitoring Kubernetes with the EFK Stack
2.1 - Overview
The EFK stack consists of three elements:
- Elasticsearch which provides:
- the storage of metrics and logs,
- Fluentd which provides:
- the collection of raw data from Kubernetes,
- sends metrics and logs to Elasticsearch,
- Kibana which enables:
- the visualization of the data stored in Elasticsearch.

2.2 - Installing the elasticsearch Chart
Start by installing the stable repository of https://charts.helm.sh :
trainee@gateway:~$ helm repo add stable https://charts.helm.sh/stable “stable” has been added to your repositories
Then install the Chart elasticsearch:
trainee@gateway:~$ helm install elasticsearch stable/elasticsearch
WARNING: This chart is deprecated
NAME: elasticsearch
LAST DEPLOYED: Sat Jul 16 11:27:22 2022
NAMESPACE: default
STATUS: deployed
REVISION: 1
NOTES:
This Helm chart is deprecated. Please use https://github.com/elastic/helm-charts/tree/master/elasticsearch instead.
---
The elasticsearch cluster has been installed.
Elasticsearch can be accessed:
* Within your cluster, at the following DNS name at port 9200:
elasticsearch-client.default.svc
* From outside the cluster, run these commands in the same shell:
export POD_NAME=$(kubectl get pods --namespace default -l "app=elasticsearch,component=client,release=elasticsearch" -o jsonpath="{.items[0].metadata.name}")
echo "Visit http://127.0.0.1:9200 to use Elasticsearch"
kubectl port-forward --namespace default $POD_NAME 9200:9200
Wait a few minutes until all Pods display a READY status:
trainee@gateway:~$ kubectl get pods NAME READY STATUS RESTARTS AGE elasticsearch-client-7869bf97bb-tb25p 1/1 Running 0 5m50s elasticsearch-client-7869bf97bb-zvl6h 1/1 Running 0 5m49s elasticsearch-data-0 1/1 Running 0 5m49s elasticsearch-data-1 1/1 Running 0 2m37s elasticsearch-master-0 1/1 Running 0 5m49s elasticsearch-master-1 1/1 Running 0 2m37s elasticsearch-master-2 1/1 Running 0 65s
Next, check for the presence of the elasticsearch-client and elasticsearch-discovery services:
trainee@gateway:~$ kubectl get services NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE elasticsearch-client ClusterIP 10.106.34.82 <none> 9200/TCP 8m23s elasticsearch-discovery ClusterIP None <none> 9300/TCP 8m23s kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 10m
2.3 - Installing fluentd-elasticsearch Chart
Install the Chart fluentd-elasticsearch from the stable repository:
trainee@gateway:~$ helm install fluentd stable/fluentd-elasticsearch --set elasticsearch.host=elasticsearch-client WARNING: This chart is deprecated W0716 12:20:08.692464 7135 warnings.go:70] spec.template.metadata.annotations[scheduler.alpha.kubernetes.io/critical-pod]: non-functional in v1.16+; use the "priorityClassName" field instead NAME: fluentd LAST DEPLOYED: Sat Jul 16 12:20:07 2022 NAMESPACE: default STATUS: deployed REVISION: 1 TEST SUITE: None NOTES: 1. To verify that Fluentd has started, run: kubectl --namespace=default get pods -l "app.kubernetes.io/name=fluentd-elasticsearch,app.kubernetes.io/instance=fluentd" THIS APPLICATION CAPTURES ALL CONSOLE OUTPUT AND FORWARDS IT TO elasticsearch . Anything that might be identifying, including things like IP addresses, container images, and object names will NOT be anonymized.
Important: Fluentd needs to know the location of the Elasticsearch host. In our case, the value is elasticsearch-client. Note therefore the use on the command line of the –set elasticsearch.host= option.
Wait a few seconds until the fluentd-fluentd-elasticsearch-xxxxx Pod displays a status of READY :
trainee@gateway:~$ kubectl get pods NAME READY STATUS RESTARTS AGE elasticsearch-client-7869bf97bb-tb25p 1/1 Running 0 10m elasticsearch-client-7869bf97bb-zvl6h 1/1 Running 0 10m elasticsearch-data-0 1/1 Running 0 10m elasticsearch-data-1 1/1 Running 0 6m51s elasticsearch-master-0 1/1 Running 0 10m elasticsearch-master-1 1/1 Running 0 6m51s elasticsearch-master-2 1/1 Running 0 5m19s fluentd-fluentd-elasticsearch-znvq5 1/1 Running 0 62s
Important: Note that when using minikube, we only have one node in the Kubernetes cluster. For this reason, we have installed only one Fluentd Pod with Helm, without using a DaemonSet.
2.4 - Installing the kibana Chart
Kibana also needs to know the location of the Elasticsearch host. This time, the value will be included in a values file. Create the file kibana-values.yaml:
To do: Copy the content from here and paste it into your file.
trainee@gateway:~$ vi kibana-values.yaml
trainee@gateway:~$ cat kibana-values.yaml
files:
kibana.yml:
## Default Kibana configuration from kibana-docker.
server.name: kibana
server.host: "0"
## For kibana < 6.6, use elasticsearch.url instead
elasticsearch.hosts: http://elasticsearch-client:9200
service:
type: NodePort
Important: Note the creation of a NodePort service. When using a DaemonSet, we would have created a ClusterIP* service of the type LoadBalancer.
Install the Chart kibana from the stable repository, referencing the values kibana-values.yaml file:
trainee@gateway:~$ helm install kibana stable/kibana -f kibana-values.yaml
WARNING: This chart is deprecated
NAME: kibana
LAST DEPLOYED: Sat Jul 16 12:22:57 2022
NAMESPACE: default
STATUS: deployed
REVISION: 1
NOTES:
THE CHART HAS BEEN DEPRECATED!
Find the new official version @ https://github.com/elastic/helm-charts/tree/master/kibana
To verify that kibana has started, run:
kubectl --namespace=default get pods -l "app=kibana"
Kibana can be accessed:
* From outside the cluster, run these commands in the same shell:
export NODE_PORT=$(kubectl get --namespace default -o jsonpath="{.spec.ports[0].nodePort}" services kibana)
export NODE_IP=$(kubectl get nodes --namespace default -o jsonpath="{.items[0].status.addresses[0].address}")
echo http://$NODE_IP:$NODE_PORT
Note the instructions at the end of the previous output which indicate how to reach Kibana from outside the cluster. Create the two variables NODE_PORT and NODE_IP and run the echo command to obtain the Kibana connection socket. Note this information:
trainee@gateway:~$ export NODE_PORT=$(kubectl get --namespace default -o jsonpath=“{.spec.ports[0].nodePort}” services kibana)
trainee@gateway:~$ export NODE_IP=$(kubectl get nodes --namespace default -o jsonpath=“{.items[0].status.addresses[0].address}”)
trainee@gateway:~$ echo http://$NODE_IP:$NODE_PORT
http://192.168.59.101:30812
Wait a few minutes until the Pod kibana-yyyyyyyy-xxxxx displays a status of READY :
trainee@gateway:~$ kubectl get pods NAME READY STATUS RESTARTS AGE elasticsearch-client-7869bf97bb-tb25p 1/1 Running 0 14m elasticsearch-client-7869bf97bb-zvl6h 1/1 Running 0 14m elasticsearch-data-0 1/1 Running 0 14m elasticsearch-data-1 1/1 Running 0 11m elasticsearch-master-0 1/1 Running 0 14m elasticsearch-master-1 1/1 Running 0 11m elasticsearch-master-2 1/1 Running 0 9m28s fluentd-fluentd-elasticsearch-znvq5 1/1 Running 0 5m11s kibana-74cd958bd4-qxmtc 1/1 Running 0 2m21s
Next, check for the presence of the NodePort service:
trainee@gateway:~$ kubectl get services NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE elasticsearch-client ClusterIP 10.106.34.82 <none> 9200/TCP 14m elasticsearch-discovery ClusterIP None <none> 9300/TCP 14m kibana NodePort 10.97.180.37 <none> 443:30812/TCP 2m49s kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 16m
2.5 - Generating Logs in Kubernetes
Now create a counter.yaml file to create a Pod that will generate continuous demo logs:
To do: Copy the content from here and paste it into your file.
trainee@gateway:~$ vi counter.yaml
trainee@gateway:~$ cat counter.yaml
## counter.yaml
apiVersion: v1
kind: Pod
metadata:
name: counter
spec:
containers:
- name: count
image: busybox
args: [/bin/sh, -c, 'i=0; while true; do echo "Demo log $i: $(date)"; i=$((i+1)); sleep 1; done']
Apply this file with the kubectl command:
trainee@gateway:~$ kubectl apply -f counter.yaml pod/counter created
Check that the counter Pod is in READY state:
trainee@gateway:~$ kubectl get pods NAME READY STATUS RESTARTS AGE counter 1/1 Running 0 17s elasticsearch-client-7869bf97bb-tb25p 1/1 Running 0 16m elasticsearch-client-7869bf97bb-zvl6h 1/1 Running 0 16m elasticsearch-data-0 1/1 Running 0 16m elasticsearch-data-1 1/1 Running 0 13m elasticsearch-master-0 1/1 Running 0 16m elasticsearch-master-1 1/1 Running 0 13m elasticsearch-master-2 1/1 Running 0 11m fluentd-fluentd-elasticsearch-znvq5 1/1 Running 0 7m15s kibana-74cd958bd4-qxmtc 1/1 Running 0 4m25s
2.6 - Visualizing Data with Kibana
Connect to your VM Gateway in VNC mode using Apache Guacamole or via an RDP connection.
Open the FireFox browser and enter the address you obtained by executing the echo command above.
Click on Explore on my own > Management > Index Patterns, then, in Create index pattern, enter the value logstash-* and click on the Next step button:
