MySQL
[MySQL]https://www.mysql.com/) is the database used in all our charts as a data store right now.
Chart Details
This chart is fully based on the Kubernetes Chart found.
It uses version 0.0.5 of our own docker image.
Get this Chart
Our central repository is located at: https://devopsku.be/charts, please configure this in your helm installation (via helm repo add). Then you can download and install this chart using the usual helm procedure (see Using Helm).
If you would like to contribute and/or like to make changes on this chart, please clone this repo via:
git clone https://github.com/devopskube/devopskube.git
Installing the chart
The installation-instructions can be found on the above mentioned Using Helm page.
Configuration
The following tables lists the configurable parameters of the SonarQuebe chart and their default values.
| Parameter | Description | Default |
|---|---|---|
cpu |
The CPU resource limit | 200m |
memory |
The RAM resource limit | 512Mi |
databaseName |
The name of the database | test |
databaseUser |
The user of the database | test |
databasePassword |
The password of the database user | test |
databaseCharset |
The Charset used in the database | utf8 |
databaseCollation |
The Collation used in the database | utf8_unicode_ci |
persistence.path |
The path where the data is stored | /data/mysql |
Specify each parameter using the --set key=value[,key=value] argument to helm install.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
$ helm install --name my-kube-lego -f values.private.yaml kube-lego-x.x.x.tgz
Tip: You can use the default values.yaml
Persistence
To be able to keep stateful data in the mysql kubernetes container, the following path is used:
/data/mysql
Tip: This path should be adopted for each database instance you set up (eg. for each application)
Right now, we do use HostPathes, which do not work in a real cluster environment (like AWS or GCE). Please adopt this one to your own needs.
Todo
- Right now SonarQube is using a MySQL version of 5.7 (this is a hardcoded requirement for MySQL), but for other Charts, we could use later versions (MariaDB)
- Use a HA/Cluster version of MariaDB/MySQL
