Kubernetes Minikube Docker trying and failing to pull image

Question

I have a docker image called docker-hello-world - all it does is print Hello World to the log using the JRE. When tested it works fine.

Then, I import an image into Kubernetes Docker and run – still no issues.

docker images -a
REPOSITORY                                             TAG                 IMAGE ID            CREATED             SIZE
docker-hello-world                                     latest              9a161d166742        20 hours ago        83.17 MB

When I try and deploy into Kubernetes with kubectl run docker-hello-world --image=docker-hello-world:latest something goes wrong here – I tried the image id as well but I can’t understand why it can’t find the image.

It says deployment created.

kubectl get deployments
NAME                 DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
docker-hello-world   1         1                1                   0           24s

kubectl get pods
NAME                                                READY     STATUS         RESTARTS   AGE
docker-hello-world-67c745cff4-sv77d   0/1       ErrImagePull   0          43s

Logs:

kubectl logs docker-hello-world-67c745cff4-sv77d
Error from server (BadRequest): container "docker-hello-world" in pod "docker-hello-world-67c745cff4-sv77d" is waiting to start: trying and failing to pull image

Im not sure why it can’t find the image.

But if I do from within Minikube:

docker build -t dummy:v1 ~/eclipse-workspace/HelloWorld/bin/

(I don’t really want do generate the image again)

docker images
REPOSITORY                                             TAG                 IMAGE ID            CREATED             SIZE
dummy                                                  v1                  beae3bfd2327        32 seconds ago      83.17 MB

kubectl run --image=dummy:v1 dummy
deployment "dummy” created

kubectl get deployments
NAME           DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
dummy          1                1           1                   0           11s

kubectl get pods
NAME                            READY     STATUS      RESTARTS   AGE
dummy-8496dd7d84-t4h66          0/1       Completed   4          1m

kubectl logs dummy-8496dd7d84-t4h66
Hello, World

It seems to work ok

Did the IP address of the machine change after you have installed minibuke? Was it working first time and started failing after IP change? — mon

The version tag of the image docker-hello-world:latest is latest, which indicates the default ImagePullPolicy is Always (see pkg/apis/core/v1/defaults.go for v1.9.x and after). It will try to pull image from the hub and not use the image already present.

One option is set a specific tag rather than latest.
