# 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.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
- Kubernetes 1.10+ with Beta APIs enabled
|
||||||
|
- PV provisioner support in the underlying infrastructure
|
||||||
|
|
||||||
|
## Installing the Chart
|
||||||
|
|
||||||
|
To install the chart with the release name `my-release`:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm install --name my-release stable/mysql
|
||||||
|
```
|
||||||
|
|
||||||
|
The command deploys MySQL on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
|
||||||
|
|
||||||
|
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`
|
||||||
|
|
||||||
|
## Uninstalling the Chart
|
||||||
|
|
||||||
|
To uninstall/delete the `my-release` deployment:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm delete --purge my-release
|
||||||
|
```
|
||||||
|
|
||||||
|
The command removes all the Kubernetes components associated with the chart and deletes the release completely.
|
||||||
|
|
||||||
|
## Configuration
|
||||||

|
||||||
|
The following table lists the configurable parameters of the MySQL chart and their default values.

|
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."*
|
||||||
|
|
||||||
|
**Notice**: You may need to increase the value of `livenessProbe.initialDelaySeconds` when enabling persistence by using PersistentVolumeClaim from PersistentVolume with varying properties. Since its IO performance has impact on the database initialization performance. The default limit for database initialization is `60` seconds (`livenessProbe.initialDelaySeconds` + `livenessProbe.periodSeconds` * `livenessProbe.failureThreshold`). Once such initialization process takes more time than this limit, kubelet will restart the database container, which will interrupt database initialization then causing persisent data in an unusable state.
|
||||||
|
|
||||||
|
## 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 initialization files
|
||||||
|
|
||||||
|
The [MySQL](https://hub.docker.com/_/mysql/) image accepts *.sh, *.sql and *.sql.gz files at the path `/docker-entrypoint-initdb.d`.
|
||||||
|
These files are being run exactly once for container initialization and ignored on following container restarts.
|
||||||
|
If you want to use initialization scripts, you can create initialization files by passing the file contents on the `initializationFiles` attribute.
|
||||||
|
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
initializationFiles:
|
||||||
|
first-db.sql: |-
|
||||||
|
CREATE DATABASE IF NOT EXISTS first DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
|
||||||
|
second-db.sql: |-
|
||||||
|
CREATE DATABASE IF NOT EXISTS second DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
|
||||||
|
```
|
||||||
|
|
||||||
|
## SSL
|
||||||
|
|
||||||
|
This chart supports configuring MySQL to use [encrypted connections](https://dev.mysql.com/doc/refman/5.7/en/encrypted-connections.html) with TLS/SSL certificates provided by the user. This is accomplished by storing the required Certificate Authority file, the server public key certificate, and the server private key as a Kubernetes secret. The SSL options for this chart support the following use cases:
|
||||||
|
|
||||||
|
* Manage certificate secrets with helm
|
||||||
|
* Manage certificate secrets outside of helm
|
||||||
|
|
||||||
|
## Manage certificate secrets with helm
|
||||||
|
|
||||||
|
Include your certificate data in the `ssl.certificates` section. For example:
|
||||||
|
|
||||||
|
```
|
||||||
|
ssl:
|
||||||
|
enabled: false
|
||||||
|
secret: mysql-ssl-certs
|
||||||
|
certificates:
|
||||||
|
- name: mysql-ssl-certs
|
||||||
|
ca: |-
|
||||||
|
-----BEGIN CERTIFICATE-----
|
||||||
|
...
|
||||||
|
-----END CERTIFICATE-----
|
||||||
|
cert: |-
|
||||||
|
-----BEGIN CERTIFICATE-----
|
||||||
|
...
|
||||||
|
-----END CERTIFICATE-----
|
||||||
|
key: |-
|
||||||
|
-----BEGIN RSA PRIVATE KEY-----
|
||||||
|
...
|
||||||
|
-----END RSA PRIVATE KEY-----
|
||||||
|
```
|
||||||
|
|
||||||
|
> **Note**: Make sure your certificate data has the correct formatting in the values file.
|
||||||
|
|
||||||
|
## Manage certificate secrets outside of helm
|
||||||
|
|
||||||
|
1. Ensure the certificate secret exist before installation of this chart.
|
||||||
|
2. Set the name of the certificate secret in `ssl.secret`.
|
||||||
|
3. Make sure there are no entries underneath `ssl.certificates`.
|
||||||
|
|
||||||
|
To manually create the certificate secret from local files you can execute:
|
||||||
|
```
|
||||||
|
kubectl create secret generic mysql-ssl-certs \
|
||||||
|
--from-file=ca.pem=./ssl/certificate-authority.pem \
|
||||||
|
--from-file=server-cert.pem=./ssl/server-public-key.pem \
|
||||||
|
--from-file=server-key.pem=./ssl/server-private-key.pem
|
||||||
|
```
|
||||||
|
> **Note**: `ca.pem`, `server-cert.pem`, and `server-key.pem` **must** be used as the key names in this generic secret.
|
||||||
|
|
||||||
|
If you are using a certificate your configurationFiles must include the three ssl lines under [mysqld]
|
||||||
|
|
||||||
|
```
|
||||||
|
[mysqld]
|
||||||
|
ssl-ca=/ssl/ca.pem
|
||||||
|
ssl-cert=/ssl/server-cert.pem
|
||||||
|
ssl-key=/ssl/server-key.pem
|
||||||
|
```

MySQL can be accessed via port 3306 on the following DNS name from within your cluster:
|
||||||
|
{{ template "mysql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
|
||||||
|
|
