## Prerequisites
- Kubernetes 1.6+ with Beta APIs enabled
- PV provisioner support in the underlying infrastructure
## Installing the Chart
By default a random password will be generated for the root user. If you'd like to set your own password change the mysqlRootPassword
in the values.yaml.
You can retrieve your root password by running the following command. Make sure to replace [YOUR_RELEASE_NAME]:
printf $(printf '\%o' `kubectl get secret [YOUR_RELEASE_NAME]-mysql -o jsonpath="{.data.mysql-root-password[*]}"`)
> **Tip**: List all releases using `helm list`
## Configuration
The following table lists the configurable parameters of the MySQL chart and their default values.
| Parameter | Description | Default |
| ------------------------------------ | ----------------------------------------- | ---------------------------------------------------- |
| `imageTag` | `mysql` image tag. | Most recent release |
| `imagePullPolicy` | Image pull policy | `IfNotPresent` |
| `mysqlRootPassword` | Password for the `root` user. | `nil` |
| `mysqlUser` | Username of new user to create. | `nil` |
| `mysqlPassword` | Password for the new user. | `nil` |
| `mysqlDatabase` | Name for new database to create. | `nil` |
| `livenessProbe.initialDelaySeconds` | Delay before liveness probe is initiated | 30 |
| `livenessProbe.periodSeconds` | How often to perform the probe | 10 |
| `livenessProbe.timeoutSeconds` | When the probe times out | 5 |
| `livenessProbe.successThreshold` | Minimum consecutive successes for the probe to be considered successful after having failed. | 1 |
| `livenessProbe.failureThreshold` | Minimum consecutive failures for the probe to be considered failed after having succeeded. | 3 |
| `readinessProbe.initialDelaySeconds` | Delay before readiness probe is initiated | 5 |
| `readinessProbe.periodSeconds` | How often to perform the probe | 10 |
| `readinessProbe.timeoutSeconds` | When the probe times out | 1 |
| `readinessProbe.successThreshold` | Minimum consecutive successes for the probe to be considered successful after having failed. | 1 |
| `readinessProbe.failureThreshold` | Minimum consecutive failures for the probe to be considered failed after having succeeded. | 3 |
| `persistence.enabled` | Create a volume to store data | true |
| `persistence.size` | Size of persistent volume claim | 8Gi RW |
| `nodeSelector` | Node labels for pod assignment | {} |
| `persistence.storageClass` | Type of persistent volume claim | nil (uses alpha storage class annotation) |
| `persistence.accessMode` | ReadWriteOnce or ReadOnly | ReadWriteOnce |
| `persistence.existingClaim` | Name of existing persistent volume | `nil` |
| `persistence.subPath` | Subdirectory of the volume to mount | `nil` |
| `resources` | CPU/Memory resource requests/limits | Memory: `256Mi`, CPU: `100m` |
| `configurationFiles` | List of mysql configuration files | `nil` |
Some of the parameters above map to the env variables defined in the [MySQL DockerHub image](https://hub.docker.com/_/mysql/).
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```bash
$ helm install --name my-release \
--set mysqlRootPassword=secretpassword,mysqlUser=my-user,mysqlPassword=my-password,mysqlDatabase=my-database \
stable/mysql
```
The above command sets the MySQL `root` account password to `secretpassword`. Additionally it creates a standard database user named `my-user`, with the password `my-password`, who has access to a database named `my-database`.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```bash
$ helm install --name my-release -f values.yaml stable/mysql
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Persistence
The [MySQL](https://hub.docker.com/_/mysql/) image stores the MySQL data and configurations at the `/var/lib/mysql` path of the container.
By default a PersistentVolumeClaim is created and mounted into that directory. In order to disable this functionality
you can change the values.yaml to disable persistence and use an emptyDir instead.
> *"An emptyDir volume is first created when a Pod is assigned to a Node, and exists as long as that Pod is running on that node. When a Pod is removed from a node for any reason, the data in the emptyDir is deleted forever."*
## Custom MySQL configuration files
The [MySQL](https://hub.docker.com/_/mysql/) image accepts custom configuration files at the path `/etc/mysql/conf.d`. If you want to use a customized MySQL configuration, you can create your alternative configuration files by passing the file contents on the `configurationFiles` attribute. Note that according to the MySQL documentation only files ending with `.cnf` are loaded.
```yaml
configurationFiles:
mysql.cnf: |-
[mysqld]
skip-host-cache
skip-name-resolve
sql-mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
mysql_custom.cnf: |-
[mysqld]
```

# MySQL
[MySQL](https://MySQL.org) is one of the most popular database servers in the world. Notable users include Wikipedia, Facebook and Google.
## Introduction
This chart bootstraps a single node MySQL deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

MySQL can be accessed via port 3306 on the following DNS name from within your cluster:
{{ template "mysql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
To get your root password run:
MYSQL_ROOT_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mysql.fullname" . }} -o jsonpath="{.data.mysql-root-password}" | base64 --decode; echo)
To connect to your database:
1. Run an Ubuntu pod that you can use as a client:
kubectl run -i --tty ubuntu --image=ubuntu:16.04 --restart=Never -- bash -il
2. Install the mysql client:
$ apt-get update && apt-get install mysql-client -y
3. Connect using the mysql cli, then provide your password:
$ mysql -h {{ template "mysql.fullname" . }} -p
To connect to your database directly from outside the K8s cluster:
{{- if contains "NodePort" .Values.service.type }}
MYSQL_HOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath='{.items[0].status.addresses[0].address}')
MYSQL_PORT=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "mysql.fullname" . }} -o jsonpath='{.spec.ports[0].nodePort}')
{{- else if contains "ClusterIP" .Values.service.type }}
MYSQL_HOST=127.0.0.1
MYSQL_PORT={{ default "3306" .Values.service.port }}
# Execute the following commands to route the connection:
export POD_NAME=$(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "mysql.fullname" . }}" -o jsonpath="{.items[0].metadata.name}")
kubectl port-forward $POD_NAME {{ default "3306" .Values.service.port }}:{{ default "3306" .Values.service.port }}
{{- end }}
mysql -h ${MYSQL_HOST} -P${MYSQL_PORT} -u root -p${MYSQL_ROOT_PASSWORD}
