Infrastructure

Common issues with deploying infrastructure services required by OpenStack are documented in the OpenStack Troubleshooting Guide.

Optional: In order to reduce the active observation time for the deployment of the components, the container images for the following services can be downloaded in advance with the argument -a pull.
```
osism apply -a pull common
osism apply -a pull loadbalancer
osism apply -a pull redis
osism apply -a pull memcached
osism apply -a pull rabbitmq
osism apply -a pull mariadb
```
Cron, Fluentd & Kolla Toolbox

The common role of Kolla is used to manage the services cron, fluentd and kolla-toolbox.

It is important to do this deployment before any other deployements in the Kolla environment, as parts of the other deployments depend on the kolla-toolbox service.
```
osism apply common
```
Loadbalancer

Have a look to the loadbalancer documentation and configure it before deploying the service.
```
osism apply loadbalancer
```
It is important to do this deployment before any other deployements in the Kolla environment, as parts of the other deployments depend on the loadbalancer service.

osism apply redis
```
Memcached
```
osism apply memcached
