Complete Application Deployment using Kubernetes Components | Kubernetes Tutorial 20

Do we need to remember the complete syntax for deployment, secret, service, etc the CKAD exam?

Thanks for good video. I am newbie on Kubernetes and I have some curious. When I create Pod without Deployment so I need to manually mange Pod, right? If Pod die then I need to restart it manually, right? Because K8S does not automatically create Deployment for me, right?

hello @TechWorldwithNana can i add this as a project in my Resume

Hello Dear, may god bless you and reward you for all the help you are providing. you deserve the best

I have followed all the steps as is, changes are mongo image instead of mongodb and mongo container is working but mongo-express is failing to connect and getting error with credentials as invalid. Can you recheck once.

I got this error "Because you are using a Docker driver on windows, the terminal needs to be open to run it." I am using Docker Desktop and only Nginx service is deployed. could you please advise me how to get it fixed ?

This session helped me a lot. Understood the E2E (basic) deployment in K8S. Thanks Nana!!

Just had a doubt. Why dont we use mongodb with statefull set but a deployment? Is it a best practice? I know stateful sets should be prevented but it is a db application right so had a little doubt there.....Thank You

how is base64 secure as a password, it can be easily converted back to ascii.

Hi Nana or someone from the comments list,
I m using docker desktop instead of minikube, can you please tell me how to run the last step(mongo express service) where you provided minikube service command, what is the command to run for the docker. Can you please let me know.

Hi, the 'containerPort' is just for documentation right? It doesn't actually expose the port? Similar to EXPOSE in dockerfile.

Oh my god that is some useful tutorials you're making!
It's just a highly-concentrated theory with an immediate practise...
Love it

Any reason why you are deploying the mongodb as a deployment instead of a statefulset?

Why is base64 considered anymore "secret" than plaintext..?

Love your videos!

I am new to K8s. Why do we need services in front of pods, can’t we specify access ports within the pod config? Is that the convention to use service in front of any pod to access it???

Im fan

Thanks a lot Nana your videos are well organized and to the point.

Hi Nada, Thanks for this wonderful video. Actually I'm using normal k8s cluster one master and two worker nodes. My loadbalancer's external IP is pending. can you pls let me know how can I fix it? Pls respond with solution.

Hi @TechWorldwithNana,
I am trying in AWS EKS cluster, could you please help me that how to connect Mongo Express through brower?

I have a yellow wave underline with VScode. Why do I get this warning all the time. Its really annoying

is anyone facing an error while applying secrets to kubectl "error when creating "mongo-secret.yaml":Secret in version "v1"cannot be handled as a Secret: illegal base64 data at input byte 13.
PS -- I am a windows user

Excellent video Nana. Thank you for posting. Super relevant and super helpful.

I tried and get a Pulling image "mongo" followed by a Warning "Back-off restarting failed container" what I'm missing?
describe gets something like terminate exit 132 - maybe a hw limitation.
What I really dislike in all the stuff is that output, logging and errors are really annoying for beginners.
often you dont understand whats wrong... Ill try to set the version to an erlier one as suggested by some thread out there. :)

=> Solution for others having this issue...using as container image "mongo:4.2.10" worked.
as also "mongo-express:0.54.0"

Very nicely explained. Thank you

Hi Nana - Great tutorial - All is working fine but I cannot get my external ip address for mongo-express-service. It continue to stay as <pending>. I don't have minikube used to install my kubernetes cluster but KubeADM... How can I get it working? thanks!

I'm unable to launch mongo-express container getting error with DB connect. Could you help me ?

Ultimate.. On point, accurate.

Except for a few typos on my part, (I like typing my files in rather than downloading, I feel more connected) this video went great. Nana, just out of curiosity (my computer isn't real stable, I'm running Folding-at-home and it crashes from time to time) if my computer crashes while all the pods and services and containers are running, as it would be at the end of this video, is there an easy way to restart everything when my computer reboots? (Besides the obvious, running all the kubectl apply commands in sequence)

Thanks a Ton!

Simply superb with great explanation.

Seriously this was of the best tutorials i have ever seen. Thank you so much Nana!

Thanks for sharing

Awesome thanks a lot

hi, I unable to pull mango and mango-express image to spin up pod. can you please share link docker hub image link on suggest if we can use other image.

You are the best!!

This video was great. Although I'm still confused on how to write to the mongodb database. I can connect to the database via web browser, but writing to it via pymongo both locally and within minikube don't work. I've been playing around with ip's and ports but still no luck

Hi Nina. At the end of the video, you first deleted the deployment and then the service. Doesn't the service depend on the deployment? Shouldn't the service be deleted first?

It's really a detailed and comprehensive video, i have followed the same steps , except creating mongo express Instead i am using mongodb compass to connect , but env var username and password not getting set . I am able to connect without credentials. can you please help here

I think you have created kubernetics and Docker .

Hi Mongo express is not coming up. can you pls suggest anything . throwing Back-off restarting failed container

pleas can you help me... how can I connect my kubernetes cluster and gitlab-aget

from my testing with Kubernetes in Docker Desktop it seems that the nodePort parameter gets ignored and the LoadBalancer service is accessible by the internal port instead (it didn't connect at all on port 30000).. I'm not sure if I did something wrong

I love your tutorials!!

I have only one question:

How to get External IP on Kubernetes Clusters installed on-premise? Do I need an external DHCP server?

Thanks,
Marco

hello nana, i followed your tutorial and everything was fine. in my case am deploying laravel with postgres database. just modifed the yaml which you have shown as er my requirement. now my problem is external ip is not generating and when i give minkube service command it shows nothing. what i have to do. please guide me

best and easy way to gain knowledge on deploying the app, thanks for the video Nana
