# MySQL installation with cinder volume plugin
|
||||
|
||||
Cinder is a Block Storage service for OpenStack. This example shows how it can be used as an attachment mounted to a pod in Kubernets.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
Start kubelet with cloud provider as openstack with a valid cloud config
|
||||
Sample cloud_config:
|
||||
|
||||
```
|
||||
[Global]
|
||||
auth-url=https://os-identity.vip.foo.bar.com:5443/v2.0
|
||||
username=user
|
||||
password=pass
|
||||
region=region1
|
||||
tenant-id=0c331a1df18571594d49fe68asa4e
|
||||
```
|
||||
|
||||
Currently the cinder volume plugin is designed to work only on linux hosts and offers ext4 and ext3 as supported fs types
|
||||
Make sure that kubelet host machine has the following executables
|
||||
|
||||
```
|
||||
/bin/lsblk -- To Find out the fstype of the volume
|
||||
/sbin/mkfs.ext3 and /sbin/mkfs.ext4 -- To format the volume if required
|
||||
/usr/bin/udevadm -- To probe the volume attached so that a symlink is created under /dev/disk/by-id/ with a virtio- prefix
|
||||
```
|
||||
|
||||
Ensure cinder is installed and configured properly in the region in which kubelet is spun up
|
||||
|
||||
### Example
|
||||
|
||||
Create a cinder volume Ex:
|
||||
|
||||
`cinder create --display-name=test-repo 2`
|
||||
|
||||
Use the id of the cinder volume created to create a pod [definition](mysql.yaml)
|
||||
Create a new pod with the definition
|
||||
|
||||
`cluster/kubectl.sh create -f examples/mysql-cinder-pd/mysql.yaml`
|
||||
|
||||
This should now
|
||||
|
||||
1. Attach the specified volume to the kubelet's host machine
|
||||
2. Format the volume if required (only if the volume specified is not already formatted to the fstype specified)
|
||||
3. Mount it on the kubelet's host machine
|
||||
4. Spin up a container with this volume mounted to the path specified in the pod definition
|
