How to Build and Deploy an app on Kubernetes by GitLab ci cd pipeline

[@imCroozen]

I've been watching ALOT of devops videos for my job this week, and this is BY FAR the most hands on devops pipeline tutorial I have found. Thank you.

[@be-devops]

Thank You

[@bothorsen4292]

Thank you for this, it was exactly what I needed. If only the gitlab documentation was as good as this video :)

[@be-devops]

Thanks

[@muhammadrehan5722]

The most underrated channel for devops i guess. This is all we need i guess simple and clear

You are the best teacher. I took so many courses, but the way you teach goes straight to my head. 🎉🎉🎉🎉

[@be-devops]

Thank you, today I started my day with your energetic sentence.

[@hajermakina7474]

This is such a structured video for those who want to build a complete cicd pipeline. and explanation was really crystal clear ! you are such a gem trainer :) you have really done a fantastic job creating this video, I hope we could get more such end to end project to grind our skills !! Thank you

[@be-devops]

You built my day with your full energetic sentences

solid video. would be even greatet with time sections since it offers so much valuable instructions.

[@rikitikitaki5919]

Good video, but you didnt mention about runner. I think it was full cicd process if you showed installing runner

[@be-devops]

Thank you for your comment Here we more focus on CICD. But i had another video about using gitlab runner: kzbin.info/www/bejne/bHPPpH6inbSbeqc

[@rikitikitaki5919]

​@be-devops Could you explain me, please. In stage deploy, do we need to use kubernetes runner? Or it is enought that we have agent. Because when i am starting my pipeline it gives me error, that here we dont have runner to deploy. Maybe i have a mistake.

[@be-devops]

@@rikitikitaki5919 no need something like you say kubernetes runner. we do not have such thing. Only agent is ok you can contact me by email and send me the issue logs and we can solve it quickly

[@ceasarpalache1045]

Make sure your k8s-connection is in the same group as the project you're trying to deploy. If it's not, the deployment step will fail trying to set kubectl contexts.

awesome video

[@hwy9nightkid]

at about 29:26 you're showing the building of the image with a public gitlab provided runner.. is the agent also capabale of building or how should one go about supporting not just operations but build steps in our private k8s? seems I need more runner types installed?

[@be-devops]

Hello, I did not get your question would you please send me more details in my email [e-mail]

[@hwy9nightkid]

I'd rather not reveal my email.. but I think I understand.. you built the docker image using gitlabs free runners... I wanted to see if you could build docker images within the k3s cluster.. but very good video thanks ! @@be-devops

[@be-devops]

@@hwy9nightkid Good Hint. I will check K3S and will try to do. Thanks

[@nikitamathur6720]

Thanks for the detailed Video. Help me alot !!! Want to ask you that when i run 'kubectl get node -o wide' and take the internal ip of the node-cluster, i am not able to connect to my app on browser. I have installed docker for windows on my windows machine. Then minicube for Kubernetes. Should i install anything else.

[@be-devops]

Please check your firewall on windows and maybe blocked it but as i described I am using Rancher Desktop and really is amazing for its installation you can check my other video: kzbin.info/www/bejne/f2q8pYWehbeAp8U

Hi Thankyou so much for your video I have made a similar lab for testing CICD Gitlab I am facing issues whule pusing the code in gitlab container I would appreciate your help

[@be-devops]

Thanks

[@eliaspereira777]

Hello, great explanation!!! I have a gitlab-ci.yml identical to yours, but in the build stage, I set the tags: build, only. The deploy is identical. When I push, the stage build completes successfully, but the stage deploy is waiting for a runner. I believe that with the gitlab agent, there is no need for a runner, correct?

[@be-devops]

yes deploy also need gitlab runner, because you are using an image to run kubectl command check yr deploy config. or send me by email to check it for you [e-mail]

[@elchinefa9524]

First of all thnaks a lot for this video. I am fasinf agent connection issue. I'm using our company gitlab server and Connect a Kubernetes cluster return an error: Gitlab Failed to register an agent GRPC::Unimplemented . By the way my kubernetes running in Proxmox and it is kubeadm cluster.

As you have created two repositories in your gitlab account, one for k8s connection and another one for source code. So, my question is, can we create only one repository for both work (connection to k8s and for source code) ?

[@be-devops]

Hi Yes you can , but for clear the result i used 2 repo

[@serokanikani]

thanks for the tutorial, I have a problem if I update coding and push to gitlab, build image and deploy successfully. but it seems like the pod or service or image in microk8s is not updated and if I delete the service and pod first then push to gitlab, its work. my gitlab ci yaml is same with tutorial

[@danishkhalid9193]

I followed your step when deploying application manually in k8s cluster , i did the same thing but i am unable to access the application using internal IP of the cluster but i am able to access it through localhost:nodeport . What might haves caused this problem or is it not a problem at all ? Thanks

[@be-devops]

[@HxHsoulseeking]

Thank you.

[@Freeline95]

Nice video! Could you give me advice by best practices. In your case you store k8s yaml files in your project repo. But i am developing microservices architecture and my files are storing in separated repo "infrastructure". How to get files from there? Git clone my private repo during the build?

[@be-devops]

Hi Friend, You can find your answer here in this video: kzbin.info/www/bejne/hafKiah9qNCXea8 I described there how to clone other repo in CICD

Thank you ! But i have never connected status !! and i have a "Failed to register agent pod. " problem ! Can you help please !?

[@be-devops]

Thank you for your comment. To make connection I would check cluster side. I suggest you when in gitlab side you create a connection, copy helm codes and past them in Cluster side. After please check if everything in cluster side working well: 1) kubectl get ns you will see the name spaces and also the one for gitlab 2) kubectl -n get pods ex: kubectl -n gitlab-agent-k8s-connection get pods the result will show you the pods should be in running status. If pods be in Running status but still you have no connection in gitlab, check your firewall You can reach me by Email.

When the Docker image has already been built in the gitlab registry. Why do we need to push it again? Won't the image be there already?

[@be-devops]

When it had been built by CICD , it is located on gitlab runner and when the job done by gitlab runner it will gone because it is a container so we need to push it on gitlab repository that be useable
