# GKE : use local domain
###### tags: `gke` `SSL`
Sometime you need to test SSL on localhost
I have a GKE cluster & I want to try ingress with a fake localhost dns like https://main.local
## set a local dns to your ingress external IP
/etc/hosts :
```
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost docker.for.mac.localhost
255.255.255.255 broadcasthost
::1 localhost
xx.xxx.xxx.xx santa.local
```
## Generate SSL cert with letsencrypt:
e.g : ssl for https://playmo.local
```
openssl req -x509 -out main.crt -keyout main.key \
-newkey rsa:2048 -nodes -sha256 \
-subj '/CN=main.local' -extensions EXT -config <( \
printf "[dn]\nCN=main.local\n[req]\ndistinguished_name = dn\n[EXT]\nsubjectAltName=DNS:main.local\nkeyUsage=digitalSignature\nextendedKeyUsage=serverAuth")
```
## Create Secret TLS on K8S
```
kubectl create secret tls tls-main --key main.key --cert main.crt
```
## Set cert trust on OSX
- Launch Application/Utilities/Keychain Access.app & upload your main.crt
- set trusted always
