# Services

The main services in Openstack that we use are:

1. Doni: enrolling workers
2. Blazar: reservations and enrolling network segments (SDRs, Adv routers, EP5G)
3. Zun: container orchestration service using k8s
4. Neutron: networking service
5. Horizon: the web interface

Check if the service's container is healthy

* Blazar:

  ```console
  (venv) expeca@controller-01:/opt/chi-in-a-box$ docker ps | grep "blazar"
  722d4ff498b5   samiemostafavi/ubuntu-source-blazar-manager:xena  ... 4 months ago   Up 3 days (healthy)   blazar_manager
  9b72ebaab4a6   samiemostafavi/ubuntu-source-blazar-api:xena      ... 4 months ago   Up 3 days (healthy)   blazar_api
  ```
* Zun:

  ```console
  (venv) expeca@controller-01:/opt/chi-in-a-box$ docker ps | grep "zun"
  e8f723aee767   samiemostafavi/ubuntu-source-zun-compute-k8s:xena  ... 2 days ago     Up 2 days (healthy)  zun_compute_k8s
  d18d7348b92d   samiemostafavi/ubuntu-source-zun-wsproxy:xena      ... 2 days ago     Up 2 days (healthy)  zun_wsproxy
  54f7dbf64c50   samiemostafavi/ubuntu-source-zun-api:xena          ... 2 days ago     Up 2 days (healthy)  zun_api
  ```

Check the service's internal logs (last 100 lines)

* Blazar:

  ```
  docker exec -it blazar_manager tail -100 /var/log/kolla/blazar/blazar-manager.log
  ```
* Zun k8s:

  ```
  docker exec -it zun_compute_k8s tail -100 /var/log/kolla/zun/zun-compute.log
  ```

If it is restarting, you can check the container logs

````
```
docker logs blazar_manager
docker logs zun_compute_k8s
```
````

Check the config files

* Blazar:

  ```
  docker exec -it blazar_manager cat /etc/blazar/blazar.conf
  ```
* Zun k8s:

  ```
  docker exec -it zun_compute_k8s cat /etc/zun/zun.conf
  ```

Restart a service

````
```
docker restart blazar_manager
docker restart zun_compute_k8s
```
````

Re-deploy a service, after some configurations were changed

````
```
./cc-ansible --site ../site-config/ deploy --tags blazar
./cc-ansible --site ../site-config/ deploy --tags zun
./cc-ansible --site ../site-config/ deploy --tags doni
```
````
