Kubernetes solve this problem by allowing users to create and launch different Kubernetes configurations and pods.So the difference in purposes leads to dependency management problems because both the teams would be obviously using different libraries as the use case is different. But a company usually have multiple workflows for different purposes like data science pipelines, production applications etc.But there’s one drawback is that Apache airflow users must use the clients and frameworks provided by airflow worker when doing the execution.Apart from that the feature of its plug-in framework makes the extensibility very simple. It provides integration support for various services used by several cloud providers and other platforms like Spark. From the begining, Airflow is known for its flexibility.For more information on Airflow Operators please read this blog. Operators are kind of a placeholders in this case that help us to define what operations we want to perform. So to do actual operations we need operators. In practical, Airflow DAGs (Directed Acyclic Graph) only represent the workflow and won’t be doing any computations (or performing operations).Most popular and one of the best workflow management systems out there with great community support.Airflow is a free to use and open-source workflow orchestration framework developed by Apache that is used to manage workflows.When I do nslookup inside Minikube, it does resolve with following information: Minikube start -vm-driver="xhyve" -insecure-registry="$REG_IP":80 Then I searched around to see if anyone has faced similar issues and it turned out that some people have and they did resolve it by restarting minikube using some more flags which look like below: So I ran kubectl describe pod command on it and the results look like following:Įvents: Type Reason Age From Message - Normal Scheduled 8m default-scheduler Successfully assigned default/ngix-67c6755c86-qm5mv to minikube Warning Failed 8m kubelet, minikube Failed to pull image "nginx": rpc error: code = Unknown desc = Error response from daemon: Get : dial tcp: lookup on 192.168.64.1:53: read udp 192.168.64.2:52133->192.168.64.1:53: read: connection refused Normal Pulling 8m (x2 over 8m) kubelet, minikube Pulling image "nginx" Warning Failed 8m (x2 over 8m) kubelet, minikube Error: ErrImagePull Warning Failed 8m kubelet, minikube Failed to pull image "nginx": rpc error: code = Unknown desc = Error response from daemon: Get : dial tcp: lookup on 192.168.64.1:53: read udp 192.168.64.2:40073->192.168.64.1:53: read: connection refused Normal BackOff 8m (x3 over 8m) kubelet, minikube Back-off pulling image "nginx" Warning Failed 8m (x3 over 8m) kubelet, minikube Error: ImagePullBackOff Now, when I do that, it spins up the pod but the status is ImagePullBackOff. Kubectl run nginx -image=nginx (Please note I do not have this image anywhere on my machine and I am expecting k8 to fetch it for me) I started minikube and things look like they are up and running. Use Kube-ctl to spin up a docker image from docker hub.I am very new to Kuberetes and I have done some work with docker previously.
