# Kubernetes Test
a simple playground for playing around with kubernetes.
Testing with minikube and kubectl on one machine.
## Requirements
a machine with at least 2 cores and 2GB RAM. And docker or any other supported container system. Here I am using docker.
## Start minikube
```bash
minikube start --driver docker
# check if all is running
minikube status
```
## Working with pods
### start everything
```bash
kubectl apply -f mongo-config.yaml
kubectl apply -f mongo-secret.yaml
kubectl apply -f mongo.yaml
kubectl apply -f webapp.yaml
```
### check the status
```bash
kubectl get all
```
output:
```
NAME READY STATUS RESTARTS AGE
pod/mongo-deployment-564b4bdfdf-gt46p 1/1 Running 0 5m16s
pod/webapp-deployment-56dbf5d695-442sz 1/1 Running 0 4m26s
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/kubernetes ClusterIP 10.96.0.1 443/TCP 49m
service/mongo-service ClusterIP 10.104.152.87 27017/TCP 5m16s
service/webapp-service NodePort 10.109.83.118 3000:30100/TCP 4m26s
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/mongo-deployment 1/1 1 1 5m16s
deployment.apps/webapp-deployment 1/1 1 1 4m26s
NAME DESIRED CURRENT READY AGE
replicaset.apps/mongo-deployment-564b4bdfdf 1 1 1 5m16s
replicaset.apps/webapp-deployment-56dbf5d695 1 1 1 4m26s
```
### check secrets
```bash
kubectl get secret
```
output:
```
NAME TYPE DATA AGE
default-token-p4bqj kubernetes.io/service-account-token 3 51m
mongo-secret Opaque 2 8m22s
```
### get details for a service
here as example for service "webapp-service"
(all running services are visible for example in `kubectl get all`)
```bash
kubectl describe service webapp-service
```
the describe param can also show many other infos, eg about the pod:
```bash
kubectl describe pod some-pod-id
```
### get the logs of a pod
```bash
kubectl logs some-pod-id
```
this will return the last log entries. To get a live stream of logs, append `-f` th that command.
### get the IP
to get the public ip for the container by using minikube:
```bash
minikube ip
```
or with cubectl:
```bash
kubectl get note -o wide
```
output:
```
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
