How to switch kubectl clusters between gcloud and minikube

I have Kubernetes working well in two different environments, namely in my local environment (MacBook running minikube) and as well as on Google's Container Engine (GCE, Kubernetes on Google Cloud). I use the MacBook/local environment to develop and test my YAML files and then, upon completion, try them on GCE. Currently I need to work with each environment individually: I need to edit the YAML files in my local environment and, when ready, (git) clone them to a GCE environment and then use/deploy them. This is a somewhat cumbersome process. Ideally, I would like to use kubectl from my Macbook

Kubernetes POD arguments are not passing to service, however Docker arguments are passing correctly

由 微笑、不失礼 提交于 2019-12-02 07:49:16
Problem Statement: I have a created a Docker image successfully from docker.io/joethecoder2/spring-boot-web . It has been tested with command line arguments, and those work correctly locally with Docker. I am trying to pass java arguments that are passed to Docker to a Kubernetes POD that is defined with a single image docker.io/joethecoder2/spring-boot-web The purpose of passing the arguments is to let the POD know what the IP address and port number are for the database service. Problem Definition: I have defined a Kubernetes POD here, however I believe the arguments are not passed correctly

How does one install the kube-dns addon for minikube?

Can someone please detail the steps necessary to install the kube-dns addon? I've downloaded the nearly 400MB git repo in the previous link and run make as instructed but get Nothing to be done for 'all'. The docs aren't clear what form add-ons exist in, and how to install them. The "Administrators guide" link there takes me to this unhelpful page. I've tried https://stackoverflow.com/a/42315074/4978821 , but got an error validating data message. Even if this worked, it seems like it'd be an unofficial and awkward solution. Answers like this are also too vague: https://stackoverflow.com/a

Routing an internal Kubernetes IP address to the host system

由 你离开我真会死。 提交于 2019-12-01 02:16:38
问题 While running Minikube, I want to connect to a server that has the annoying habit of announcing itself to a service registry with its internal IP address from inside its pod. However for legacy reasons I have to connect to this registry first and retrieve that server's ip address from it. The only way to access this server from my dev machine, it seems to me, is bridging to the internal network, so I can access the networking of the Minikube. Is there an easy way to do this? 回答1: You can add

Calling an external service from within Minikube

由 萝らか妹 提交于 2019-11-30 20:29:12
问题 I have a service (/deployment/pod) running in my Minikube (installed on my Mac) that needs to call an external http service that runs directly on my Mac (i.e. outside Minikube). The domain name of that external service is defined into my Mac /etc/hosts file. Yet, my service within Minikube cannot call that external service. Any idea what I need to configure where? Many thanks. C 回答1: Create Endpoints that will forward traffic to your desire external IP address (your local machine). You can
