问题
I've build docker image locally:
docker build -t backend -f backend.docker
Now I want to create deployment with it:
apiVersion: apps/v1
kind: Deployment
metadata:
name: backend-deployment
spec:
selector:
matchLabels:
tier: backend
replicas: 2
template:
metadata:
labels:
tier: backend
spec:
containers:
- name: backend
image: backend
imagePullPolicy: IfNotPresent # This should be by default so
ports:
- containerPort: 80
kubectl apply -f file_provided_above.yaml
works, but then I have following pods statuses:
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
backend-deployment-66cff7d4c6-gwbzf 0/1 ImagePullBackOff 0 18s
Before that it was ErrImagePull
. So, my question is, how to tell it to use local docker images? Somewhere on the internet I read that I need to build images using microk8s.docker
but it seems to be removed.
回答1:
Found docs on how to use private registry: https://microk8s.io/docs/working
First it needs to be enabled:
microk8s.enable registry
Then images pushed to registry:
docker tag backend localhost:32000/backend
docker push localhost:32000/backend
And then in above config image: backend
needs to be replaced with image: localhost:32000/backend
