I'm trying to access a MySQL database hosted inside a docker container on localhost from inside a minikube pod with little success. I tried the solution described Minikube expose MySQL running on localhost as service but to no effect. I have modelled my solution on the service we use on AWS but it does not appear to work with minikube. My service reads as follows
apiVersion: v1
kind: Service
metadata:
name: mysql-db-svc
namespace: external
spec:
type: ExternalName
ExternalName: 172.17.0.2
...where I try to connect to my database from inside a pod using "mysql-db-svc" on port 3306 but to no avail. If I try and CURL the address "mysql-db-svc" from inside a pod it cannot resolve the host name.
Can anybody please advise a frustrated novice?
I'm using ubuntu with Minikube and my database runs outside of minikube inside a docker container and can be accessed from localhost @ 172.17.0.2. My Kubernetes service for my external mysql container reads as follows:
kind: Service
apiVersion: v1
metadata:
name: mysql-db-svc
namespace: external
spec:
type: ExternalName
externalName: 10.0.2.2
Then inside my .env for a project my DB_HOST is defined as
mysql-db-svc.external.svc
... the name of the service "mysql-db-svc" followed by its namespace "external" with "svc"
Hope that makes sense.
