MySQL

Usage example

Example 
apiVersion: aiven.io/v1alpha1
kind: MySQL
metadata:
  name: my-mysql
spec:
  authSecretRef:
    name: aiven-token
    key: token

  connInfoSecretTarget:
    name: mysql-secret
    prefix: MY_SECRET_PREFIX_
    annotations:
      foo: bar
    labels:
      baz: egg

  project: my-aiven-project
  cloudName: google-europe-west1
  plan: business-4

  maintenanceWindowDow: sunday
  maintenanceWindowTime: 11:00:00

  userConfig:
    backup_hour: 17
    backup_minute: 11
    ip_filter:
      - network: 0.0.0.0
        description: whatever
      - network: 10.20.0.0/16

Info

To create this resource, a Secret containing Aiven token must be created first.

Apply the resource with:

kubectl apply -f example.yaml

Verify the newly created MySQL:

kubectl get mysqls my-mysql

The output is similar to the following: 

Name        Project             Region                 Plan          State      
my-mysql    my-aiven-project    google-europe-west1    business-4    RUNNING

To view the details of the Secret, use the following command: 

kubectl describe secret mysql-secret

You can use the jq to quickly decode the Secret:

kubectl get secret mysql-secret -o json | jq '.data | map_values(@base64d)'

The output is similar to the following:

{
    "MYSQL_HOST": "<secret>",
    "MYSQL_PORT": "<secret>",
    "MYSQL_DATABASE": "<secret>",
    "MYSQL_USER": "<secret>",
    "MYSQL_PASSWORD": "<secret>",
    "MYSQL_SSL_MODE": "<secret>",
    "MYSQL_URI": "<secret>",
    "MYSQL_REPLICA_URI": "<secret>",
    "MYSQL_CA_CERT": "<secret>",
}
