I'm trying to use confluent helm chart following this link https://github.com/confluentinc/cp-helm-charts/tree/e17565cd5a6985a594155b12b08068cb5882e51f/charts/cp-kafka-connect but when I install it on minikube I got ImagePullBackOff

confluent-oss3-cp-control-center-5fc8c494c8-k25ps    0/1     ImagePullBackOff   0          76m
confluent-oss3-cp-kafka-0                            0/2     ImagePullBackOff   0          76m

confluent-oss3-cp-schema-registry-6b8d69887d-5cmvt   0/2     ErrImagePull       0          76m
confluent-oss3-cp-zookeeper-0                        0/2     ImagePullBackOff   0          76m

Is there any solution to fix this problem ?
