Description
The envsetup live group includes all the hosts that will process lives streams.
In a standard Ubicast case, the host is the same as the mediaserver.
In a HA Ubicast case, the live is usually a cluster of two dedicated servers behind a loadbalancer VIP setup in active/backup.
Prerequisites
The live group playbooks actions must be played after the mediaserver playbook actions otherwise the live playbook will throw an error when configuring nginx on the mediaserver hosts.
Usage
Description
You can setup a standard case by setting the ip_live value to 127.0.0.1 in your inventory (or leave it blank as it is the default value).
For a HA case, you will have to setup the live cluster VIP address in the ip_live variable.
Ansible
Inventory variables
| Name | Default | Description |
|---|---|---|
| ip_live | 127.0.0.1 | IP/DNS to reach the live server/cluster from the MediaServer point of view |
| live_domain | Domain name of the live cluster (only if distinct live server(s) from MediaServer) | |
| tmpfs_size | 2048m | Size of the tmpfs storing the live chunks (unit g or m and only if distinct live server(s) from MediaServer) |
Note: See the ubicast prerequisites for details on the tmpfs size (Although 2048m should cover most of the non-intensive cases)
Usage examples
Standard case
- To deploy the live cluster with a global deployment
cd <envsetup dir>/ansible
ansible-playbook -i inventory/<inventory name> playbooks/site.yml- To deploy only the live cluster and the Ubicast global tools
cd <envsetup dir>/ansible
ansible-playbook -i inventory/<inventory name> playbooks/live/deploy-standalone.yml- To deploy only the live cluster without the Ubicast global tools
cd <envsetup dir>/ansible
ansible-playbook -i inventory/<inventory name> playbooks/live/deploy-minimal.ymlHA case
