Create Development Environment with Kubernetes Clusters in your mac (with MySQL, ElasticSearch)

At First

I created development environment in minikube. I took some times to setup keep Volume in own machine.

Finally, I created NFS in my mac and k8s volume mount to it. This article only about macOSX. You have to create shared folder in your VM if you use windows.

Versions

Commands

Setup NetworkFileSystem

in macOS

$ sudo mkdir /Users/Shared/mysql
$ sudo chmod 777 /Users/Shared/mysql
$ sudo vi /etc/exports

# add following lines
/crm/mysql -maproot=root:mysql -network 192.168.99.0 -mask 255.255.255.0

$ sudo nfsd update
$ sudo showmount -e
Exports list on localhost:
/Users/Shared/mysql                 192.168.99.0
/Users/Shared/elasticsearch         192.168.99.0

192.168.99.1 is minikube’s IP address in MacOS. I added access permission from minikube.

start VM and minikube
$ minikube start --disk-size 20g
$ minikube status
minikube: Running
cluster: Running
kubectl: Correctly Configured: pointing to minikube-vm at 192.168.99.100
Create pods with skaffold
$ skaffold dev

check your pods’ status :

$ kubectl get po
NAME                         READY     STATUS    RESTARTS   AGE
api-http-779f4558cb-5zntl    3/3       Running   0          15m
api-mysql-86cf68bfdb-hltnn   1/1       Running   1          44m

or you can check on GUI : minikube dashboard

skaffold build containers when you changed project files. You should wait a second after saving file.

[api-http-779f4558cb-5zntl api] [09-May-2018 17:30:34] NOTICE: ready to handle connections

If you don’t wanna use skaffold

You can develop without skaffold to following steps :

$ cd /path/to/api-bizcrm
$ eval $(minikube docker-env)
$ export VERSION=<set your version>
$ docker build -f Dockerfile.minikube -t api-bizcrm:$VERSION .
$ kubectl set image deployment/api-http api=api-bizcrm:$VERSION
deployment.apps "api-http" image updated

but I think it’s too tedious process to develop.
