# Kubernetes
382+
383+
Install helm:
384+
`brew install kubernetes-helm` - see [installation guide](https://docs.helm.sh/using_helm/#installing-helm)
385+
386+
Install helm client with `helm init`
387+
388+
To get Helm support in PhpStorm make sure to get v2018.3+
389+
390+
## Manual steps (workarounds)
391+
1. `sudo chmod a+w .` needed to allow write permissions over NFS since users are different on the guest and host
392+
2. `chmod a+x magento/bin/magento`

# Magento Kubernetes components

3+
Install minikube.
4+
5+
Start minikube. And use docker env.
6+
7+
```bash
8+
minikube start
9+
eval $(minikube docker-env)
10+
```
11+
12+
Install helm (cluster should be run to set tiller). [Install guide](https://docs.helm.sh/using_helm/#installing-helm)
13+
14+
15+
## NFS server (optional)
16+
17+
Configure your sources directory as export (/etc/exports) in the NFS server that runs on your host machine. This way containers can mount source code. This is a lot faster than a default VirtualBox shared folder mount. You only have to do this once, the NFS service will load /etc/exports at (re)boot.
18+
19+
NOTE: The Minikube IP can be different after a minikube delete and minikube start command. Make sure that your NFS export contains the correct Minikube IP again.
20+
21+
[More info](http://pietervogelaar.nl/minikube-nfs-mounts)
22+
23+
### Mac OS X
24+
If you do not have python, install it using brew:
25+
```bash
26+
brew install python
27+
```
28+
echo "$(python -c 'import os,sys;print(os.path.realpath(".")')/sources -alldirs -mapall="$(id -u)":"$(id -g))" $(minikube ip)" | sudo tee -a /etc/exports && sudo nfsd restart
29+
Check if the entry is active by executing on your host machine:
30+
31+
```bash
32+
showmount -e 127.0.0.1
33+
```
34+
35+
This should output something like:
36+
37+
```bash
38+
Exports list on 127.0.0.1:
39+
/Absolute/path/to/magento 192.168.99.100
40+
```
41+
42+
There is also variable in values.yml which should be enabled
43+
44+
## Run deployments
45+
46+
Configuration values located in values.yaml
47+
48+
To run all charts execute next command:
49+
50+
```bash
51+
helm install --values values.yaml .
52+
```
53+
54+
(temporary) Magento sources should be cloned to source path in current chart and in checkout subchart as well.
55+
56+
DB password autogenerated in container, to check it list pods:
57+
```bash
58+
kubectl get pods
59+
```
60+
61+
choose one of mysql pods end run bash in it:
62+
63+
```bash
64+
kubectl exec -it release-1-some-mysql-pod bash
65+
```
66+
67+
Observe env variables with prefix MYSQL_
68+
69+
## Clean
70+
71+
To delete releases run:
72+
```
73+
helm delete $(helm list -q)
74+
```
