I am trying to install Containerized Private Minion but facing error in below
Using a Dockerfile, while making a custom image that allows containers created from them to establish a SSL handshake with endpoints, The error appears as below.
Here I have added command to create /etc/certs since it is not pre existing. Also I am not sure if /opt/java/openjdk/lib/security/cacerts exists on container
FROM quay.io/newrelic/synthetics-minion:latest
RUN mkdir /etc/certs
COPY Cert.pem /etc/certs
RUN keytool -noprompt -import -alias proxy -file /etc/certs/Cert.pem -keystore /opt/java/openjdk/lib/security/cacerts -storepass changeit
I used docker build minionwithcert , but the image created had no repo name & was , I manually tagged the image with a name. It looks like to me the custom image was not properly created, & either the Dockerfile is wrong or a mistake in docker run command.
Error:
Failed to pull image "minionwithcert:3.0.65": rpc error: code = Unknown desc = Error response from daemon: pull access denied for minionwithcert, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

If you want to test an image locally, use its IMAGE ID. Example:
If your image is:
docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
<none> <none> a1510947ccde 2 minutes ago 436 MB
You can run it using:
docker run a1510947ccde
Once you tag it, docker tries to download it from a registry.

Learning docker following a course in udemy. i have all the prerequisites like docker desktop and switched to windows container. While trying to run a container using
docker container run docker4dotnet/nanoserver hostname
getting error like below

unable to figure it out. can some one help on this
NOTE : tried to switch the container to linux but it says

docker: image operating system "windows" cannot be used on this platform.
NOTE 2 : Even tried
docker run -d -p 8090:80 docker/getting-started it says below even though windows container is selected
PS C:\WINDOWS\system32> docker run -d -p 8090:80 docker/getting-started
docker: Error response from daemon: operating system on which parent image was created is not Windows.
use this lines in cmd:
docker pull mcr.microsoft.com/windows/nanoserver:20H2
docker container run mcr.microsoft.com/windows/nanoserver:20H2 hostname
I have logged in to the Docker hub using the CLI command: docker login. Entered username and password and I can pull and push images to Docker hub.
However, my K8S can't. I am trying to apply a deployment that should pull those images into its pods but I got the following error when running kubectl describe pod POD_NAME:
Warning Failed 9s kubelet Failed to pull image "myprivate/repo:tag": rpc error: code = Unknown desc = Error response from daemon: pull access denied for myprivate/repo, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
How to make the docker run in the pods to also be logged to the docker hub as well as doing it from my terminal?
Create "image pull secret" and define on your deployment. Here is how you can do https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/
I am pulling image from my local docker registry provider by nexus 3 in kubernetes cluster, but throw this error:
Failed to pull image "192.168.31.2:8080/goharbor/harbor-portal:v2.0.1": rpc error: code = Unknown desc = error pulling image configuration: unknown blob
when I execute this command using docker in k8sslave3 host machine:

I am read the question and tell me the docker image does not exists. But when I execute pull in 192.168.31.2, the output like this:
[dolphin#localhost docker]$ sudo docker pull 192.168.31.2:8080/goharbor/harbor-portal:v2.0.1
[sudo] password for dolphin:

so now I am confusing, what should I do to fix this problem? this is the docker image in nexus repository:

That is rather expected that it works if you pull the image from the host that hosts the registry.
As you created the tag from that host, the Docker client doesn't need to pull anything from the private registry, it returns directly the image from the local Docker registry of the host.
Look at the message :
Status: Image is up to date for
192.168.31.2:8080/goharbor/harbor-portal:v2.0.1
Your image configuration/data is very probably corrupted in the registry.
Try to reupload it and check also that its size is not too big (several GBs may be too much sometimes) because it may create some troubles in registry uploading/storing.

Any advice on how to proceed?
Your docker engine is trying to contact the registry and having some sort of CDN, firewall, or corporate proxy issue trying to have a proper "conversation" with the registry. It's pretty similar to being on hotel or public WiFi that has a "walled garden" that hasn't been processed through yet.
Unless you have a persistent network issue, it could be temporal, and as someone else suggested a docker pull hello-world:latest may work. If you have a corporate proxy, you may have to make sure the Docker toolbox/Docker for Windows configuration has this proxy configured properly to have network access.
