MySQL
Component format
To setup MySQL state store create a component of type state.mysql. See this guide on how to create and apply a state store configuration.
apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
name: <NAME>
namespace: <NAMESPACE>
spec:
type: state.mysql
version: v1
metadata:
- name: connectionString
value: "<CONNECTION STRING>"
- name: schemaName
value: "<SCHEMA NAME>"
- name: tableName
value: "<TABLE NAME>"
- name: pemPath
value: "<PEM PATH>"
Warning
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here.If you wish to use MySQL as an actor store, append the following to the yaml.
- name: actorStateStore
value: "true"
Spec metadata fields
| Field | Required | Details | Example |
|---|---|---|---|
| connectionString | Y | The connection string to connect to MySQL. Do not add the schema to the connection string | Non SSL connection: "<user>:<password>@tcp(<server>:3306)/?allowNativePasswords=true", Enforced SSL Connection: "<user>:<password>@tcp(<server>:3306)/?allowNativePasswords=true&tls=custom" |
| schemaName | N | The schema name to use. Will be created if schema does not exist. Defaults to "dapr_state_store" | "custom_schema", "dapr_schema" |
| tableName | N | The table name to use. Will be created if table does not exist. Defaults to "state" | "table_name", "dapr_state" |
| pemPath | N | Full path to the PEM file to use for enforced SSL Connection | "/path/to/file.pem", "C:\path\to\file.pem" |
Setup MySQL
Dapr can use any MySQL instance - containerized, running on your local dev machine, or a managed cloud service.
Run an instance of MySQL. You can run a local instance of MySQL in Docker CE with the following command:
This example does not describe a production configuration because it sets the password in plain text and the user name is left as the MySQL default of “root”.
docker run --name dapr-mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:latest
We can use Helm to quickly create a MySQL instance in our Kubernetes cluster. This approach requires Installing Helm.
Install MySQL into your cluster.
helm repo add bitnami https://charts.bitnami.com/bitnami helm install dapr-mysql bitnami/mysqlRun
kubectl get podsto see the MySQL containers now running in your cluster.Next, we’ll get our password, which is slightly different depending on the OS we’re using:
Windows: Run
[System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($(kubectl get secret --namespace default dapr-mysql -o jsonpath="{.data.mysql-root-password}")))and copy the outputted password.Linux/MacOS: Run
kubectl get secret --namespace default dapr-mysql -o jsonpath="{.data.mysql-root-password}" | base64 --decodeand copy the outputted password.
With the password you can construct your connection string.
If you are using MySQL on Azure see the Azure documentation on SSL database connections, for information on how to download the required certificate.
Non SSL connection
Replace the <CONNECTION STRING> value with your connection string. The connection string is a standard MySQL connection string. For example, "<user>:<password>@tcp(<server>:3306)/?allowNativePasswords=true".
Enforced SSL connection
If your server requires SSL your connection string must end with &tls=custom for example, "<user>:<password>@tcp(<server>:3306)/?allowNativePasswords=true&tls=custom". You must replace the <PEM PATH> with a full path to the PEM file. The connection to MySQL will require a minimum TLS version of 1.2.
