Michael, thank you so much! You showed us very useful architecural approach: "setup once, run everywhere". With this approach we don't need to be bothering with logging in our microservices at all, because ELK ingests the console output stictly to Elastic DB. It took me some time to get this runned with few corrections of your original files (i.e. "ssl_certificate_verification => false" was required to get logstash being able to connect Elastic and now Elastic requires https connection) + it was needed to bootstrap Elastic's password. Besides it, I was able to get this working and adsorb the logs of all of my microservices in ALL namespaces, despite on ELK lives in its own namespace. Keep it up, nice work!
You seem to be a bit confused about how one deploys a Helm chart. The values.yaml is not "what allows us to override the templates", those are the default values to be overridden using the -f option of helm install. You don't clone the chart to install it
Great video! Thank you I wonder if you could review the repo and update the version of the services. It seems not to be working if I try to update the service version
Thank you very much, you help me a lot. How should work to have the logs of the others containers? I just seen the ELK Stack, but a application with logs is not showing
Thanks for sharing, very good explanation. would you please also share what is the log retention policy? like for how many days it will preserve the logs and then purge them?
how do i configure my filebeat to get 100's of my pod logs. 100 pod logs -> file beat-> logstash-> elasticsearch. we have nearly 100 pods running in our kubernetes namespace
Nice Tutorial , It's helping a lot ! Just to ask , When deploying elastic search using helm chart it automatically creates pv,pvc and storageclass but when actually deployed it only created pvc the pv and storageclass is missing .. which eventually resulted into error "pod has unbound immediate PersistentVolumeClaims. preemption: 0/3 nodes are available: 3 Preemption is not helpful for scheduling.." how to resolve this issue ..
Hi Michael, firstly thank u for such a concise lecture but there is one problem that I am facing is that elasticsearch is by default configured to take data at https port while we are making logstash send data on http port, so how do I configure elasticsearch to accept data on its http port as because of this no data is being sent to it. Please help with it as I have checked multiple resources but no one has got a solution to it. It would be great if you'd throw some light on it.
couldn't able to run kibana like you did, the current chart of kibana has pre and post actions and it is causing all the problem while installing and uninstalling the chart.
while installing logstack iam getting error Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: resource mapping not found for name: "logstash-logstash-pdb" namespace: "" from "": no matches for kind "PodDisruptionBudget" in version "policy/v1beta1" ensure CRDs are installed first
Finally I made it to connect to the kibana UI, but only using the forward button in Lens. I still cannot access the UI using my regular kubernetes IP. And I don't understand how you made it to configure the nginx. I would appreciate if you would spend more time for the next tutorial, because it was way to fast for me.
Thanks for the video. Can you please help me understand.. 1. How did you setup external-ip to Kibana Pod? 2. Can I implement this solution in AKS? I lokk forward to your response..
@mguay * Ingress.extensions "kibana-kibana" is invalid: spec.rules[0].http.paths[0].pathType: Required value: pathType must be specified having this error while installing kibana, could you please help with solution..?
hi @demotest-vr4uh, I got the same issue as well, and its simple to fix it. Basically it omit the "pathtype" inside the value.yaml of kibana ingress section, checkout the other folder (firebase, elasticsearch they all have the "pathtype" in their ingress section), hope this could help you out!
Great video! I was wondering if someone has a similar issue I'm having, the pre installation test for kibana is failing for me. I think the kibana pod is unable to locate the elasticsearch tls certificate on startup which is giving me the Error: connect ECONNREFUSED. anyone had this issue ?
Hello Michael, thanks for the video , I got stucked at min 14:19, cause as i run in the current directory logstash , it outputs this error: Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: resource mapping not found for name: "logstash-logstash-pdb" namespace: "" from "": no matches for kind "PodDisruptionBudget" in version "policy/v1beta1" ensure CRDs are installed first
@Michael Thanks nice video and explanation.. i would like to impersonate roles and permissions in ELK Stack.. like want use the ELK security feature.. to create different logins for dev_user, dashboard_only_user..etc.. segregating app1, app2..with data1, data2.. etc
This is a useful video. At the end I noticed your message property was a json string. Have you looked into parsing that with Logstash, so each property displays nicely in elastic? Also is there a reason you download the helm charts locally and modify the default values.yaml, rather than just providing your own override file during the install?
Thanks! I agree with your good suggestion to parse the JSON. Additionally, I choose to override the templates directly for simplicity - but I agree with you it makes more sense to override in a values.yaml
2024 For those who are getting: "Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: resource mapping not found for name: "logstash-logstash-pdb" namespace: "" from "": no matches for kind "PodDisruptionBudget" in version "policy/v1beta1" ensure CRDs are installed first" you have to replace "policy/v1beta1" with "policy/v1" (in two different files)
Outdated video Elastic and KIbana not working !! Elastic is never getting ready in single node cluster ie: minikube, Kibana throwing weird error that i cant even understand. Pls make a new one or delete this as this video is does not work as of 2023

You are awesome. Everything worked for me and now I have a complete ELK cluster. Thanks. :-)

Thanks Michael ,
whats the cost of running elk stack vs Prometheus within k8 cluster ..which is more recommended?
Good video idea!
i tried it with a simple aks cluster (1 node B2ms), but no success. elastic search says insufficient cpu, kibana gives an ingess issue. any idea?
yes, i had the same issue. Any solution?
Learnt a lot with your video. Thanks for sharing.
nice and precise tutorial, wanted to know some changes we might have to do when the container runtime is "containerd" like in my case i am using k3s
Thanks! The setup should be quite similar, you just might have a different path to your container logs.
couldn't able to run kibana like you did, the current chart of kibana has pre and post actions and it is causing all the problem while installing and uninstalling the chart.
same problem

Basically it omit the "pathtype" inside the value.yaml of kibana ingress section, checkout the other folder (firebase, elasticsearch they all have the "pathtype" in their ingress section), hope this could help you out!
And kibana is prompting me for a user account. I don't understand which user to take. So I'm unable to get to the Kibana dashboard
elastic search not accepting the empty password connection, have you done any changes in the value file for the auth?
did you got what the password is?
Thanks, this was very helpful for me

HOw can i fix it !! maybe there is some error in the helm file, and i have already cloned the repo.
you need to change policy/v1beta1 to policy/v1 in logstash/poddisruptionbudget.yml
Same for elasticsearch@@ervispojana118
@@ervispojana118 remove beta1 just keep it has "policy/v1" in all yaml files
"policy/v1"
@Michael Thanks nice video and explanation.. i would like to impersonate roles and permissions in ELK Stack.. like want use the ELK security feature.. to create different logins for dev_user, dashboard_only_user..etc.. segregating app1, app2..with data1, data2.. etc
buddy you know that you can select multiple files and hit delete once right !! but other than that huge stuff goog work
Thanks dude, this helped a lot !
Great Video, but im getting logstash Permission denied - /var/log/containers/ any fix for this?
Which path do we need to provide in filebeat log path?
This is a useful video. At the end I noticed your message property was a json string. Have you looked into parsing that with Logstash, so each property displays nicely in elastic?

you make this look so easy!! great thanks!!
Excellent Video.
Great video! Thanks
can we use this is in kubernetes production ?
I am trying to deploy on AKS (azure kubernetes service) and getting below error:
Good one
Outdated video
Elastic and KIbana not working !! Elastic is never getting ready in single node cluster ie: minikube, Kibana throwing weird error that i cant even understand.
Pls make a new one or delete this as this video is does not work as of 2023
yeah same fpr me! old tech videos that doesnt adjust to changes can be such a time waster.
@mguay

could u please help with the issue?
try like this "policy/v1"
