Pull Image from Private Docker Registry in Kubernetes cluster | Demo
This video is a demo of deploying your application image from private docker registry hosted on AWS | Kubernetes pull image from private registry | Kubernetes Docker login
I answer the question of how to get your docker images in your kubernetes cluster from private docker registries?
For images like Mongodb, elastic, that are hosted on docker hub, it’s straightforward because they are hosted in a public repository and anyone can access them. But your own application lives in a private repository and needs explicit access from the cluster. So how do you pull the application images from your private docker repository on kubernetes cluster?
You do that using 2 steps:
1) you create a secret component that contains access token/credentials to your docker registry.
2) you configure your Deployment component to use that secret using a specific imagePullSecrets.
In the video I show you exactly this.

May 09, 2022 03:06 amI am getting an error in k8s cluster saying the "Container image "image/name:v1" already present on machine. How can I delete that image ?

May 09, 2022 03:06 amI am stucked at minute 7:26 when you run the docker login command from within Minikube (after you do minikube ssh). I am not using an AWS registry but rather a Nexus OSS in my host machine on port 8082. When I run the docker login command from within minikube as follows:
docker login host.minikube.internal:8082
hit enter and in the prompt for user name and password I enter those I get the following error:
Error response from daemon: Get "https://host.minikube.internal:8082/v2/": http server gave http response to HTTPS client.
I have tried starting my minikube with (and different version of that with http:// in front):
minikube start –driver=docker –insecure-registry=host.minikube.internal:8082
and I still get the same error. It is really frustrating.
Anyone know how do I get passed that?

can you pls support here

May 09, 2022 03:06 amAfter docker pull from a registry, how do we use the image on the local machine in k8s deployment file. IamgePullPolicy = never did not work
Adam Lang
May 09, 2022 03:06 amBig fan of your channel and I recommend it to everyone.
Your instructions for this are good, but how does this all change when not using Docker for the runtime (the supported containerd for example)? I've been having a heck of a time trying to find comparable instructions for ECR and containerd.

May 09, 2022 03:06 amMany Thanks for creating the video..though this is bit complicated. Still nice explanation.

May 09, 2022 03:06 amIs this somehow the command is changed. I couldn't find the "get-login" from ecr command, just get-login-password.
Ramesh Pattipaka
May 09, 2022 03:06 amThanks.. Clear explanation
Nish
May 09, 2022 03:06 aminstead of pull, can we make a push? basically automatic deployment on code push. is it good practice? if yes, then how to trigger k8 for pull?
My guess: runner script should login in k8 and perform apply command. Nana, what you think?
Bence Dergez
May 09, 2022 03:06 amthis is way more complex that I tought

May 09, 2022 03:06 amWhat about local docker registry on your local machine. I mean if you spin up a registry:2 container for example that will act as your private local registry. The same steps apply?
Thanks

May 09, 2022 03:06 amThe dockerconfigjson expires every 12 hours, how should we make changes in the secrets so that the we can create deployment without making any changes?

May 09, 2022 03:06 amHello Nana, How Kubernetes pull the images from private local docker registry. Could please comment on the same how can we achieve this using private local docker registry in Kubernetes cluster.
Link for setting up private registry: https://docs.docker.com/registry/
NOTE: Not on Mimikube

May 09, 2022 03:06 amHi Nana,
Excellent tutorials. Thank you.
I've created a Private Registry for my local development using Docker's Image :
"docker run -d -p 5000:5000 –restart=always –name registry registry:2"
I did not create TLS or UserName/Pwdd for this.
After creating an Image, I am able to push/pull from this Registry using cmd-line.
However, when trying using a Deployment.yaml into minikube, the Pods are not getting created.
and I get this error:
Failed to pull image "<image-name>": rpc error: code = Unknown desc = Error response from daemon: Get https://<my-registry>/v2/: http: server gave HTTP response to HTTPS client
Do I have to create TLC and Username/Pwd for this to work ?
Thanks.

Thank you

May 09, 2022 03:06 amThanks for the great video! This does seem like an overly complicated process in general. But thank you for making this.

May 09, 2022 03:06 amAnd with Podman?
Sami Khammar
May 09, 2022 03:06 ami did exactly the same and i'm getting this error when i describe the pod:
Failed to pull image "registry.gitlab.com/###/###:master": rpc error: code = Unknown desc = Error response from daemon: Get https://registry.gitlab.com/……" denied: access forbidden
i created a GitLab "Deploy token" then created a Secret using your 2nd method (one line way.) , when i use same token in simple Minkube's docker login , i m able to pull the image normally. but when i use kubectl, it's not able to pull it and getting "access forbidden" error.
Ps: everything in same namespace

May 09, 2022 03:06 amNana, just to let you know:
I was facing an issue when trying to pull a image from a private dockerhub repo. I did this in an Openshift 4.3 cluster (not mine, it is a private cluster from the company I work for) exactly how you showed in the video and it works fine! Fun fact: I found your video without even looking for it haha.
I'm already subscribed, I won't dare to miss a video from now on!
Amapramaadhy
May 09, 2022 03:06 amAmazing content as always. How do you deal with the case that the ECR logging typically expires after N hours. What’s the recommended practice in that case. Run a cron to update the configmap?
Paolo Polendey
May 09, 2022 03:06 amHello. How will I make Kubernetes automatically pull an image from the private repository if there has been a new image available? 😊 thanks in advance.
