Installing on Kolla Ussuri

1] Plan for Deployment
Please ensure that the TrilioVault Appliance has been updated to the latest hotfix before continuing the installation.
1.1] Select backup target type
Backup target storage is used to store backup images taken by TrilioVault and details needed for configuration: 
Following backup target types are supported by TrilioVault. Select one of them and get it ready before proceeding to the next step.
a) NFS
Need NFS share path 
b) Amazon S3
- S3 Access Key
- Secret Key
- Region
- Bucket name
c) Other S3 compatible  storage (Like, Ceph based S3)
- S3 Access Key
- Secret Key
- Region
- Endpoint URL (Valid for S3 other than Amazon S3)
- Bucket name

You will find the TrilioVault related parameters at the end of globals.yml file.
Details like TrilioVault build version, backup target type, backup target details, etc need to be filled out.
Following is the list of parameters that the usr needs to edit.
Parameter
Defaults/choices

Set to True when:
SSL enabled with self-signed certificates or issued by a private authority.
In the case of a different registry than docker hub, TrilioVault containers need to be pulled from docker.io and pushed to preferred registries. 
Following are the triliovault container image URLs. 
Replace kolla_base_distro and triliovault_tag variables with their values.
1
1. docker.io/trilio/{{ kolla_base_distro }}-binary-trilio-datamover-api:{{ triliovault_tag}}

5] Enable TrilioVault Snapshot mount feature
To enable TrilioVault's Snapshot mount feature it is necessary to make the TrilioVault Backup target available to the nova-compute and nova-libvirt containers.
Edit /usr/local/share/kolla-ansible/ansible/roles/nova-cell/defaults/main.yml and find nova_libvirt_default_volumes variable. Append the TrilioVault mount bind /var/trilio:/var/trilio:shared to the list of already existing volumes.
For a default Kolla installation, will the variable look as follows afterward:
1
nova_libvirt_default_volumes:
2
  - "{{ node_config_directory }}/nova-libvirt/:{{ container_config_directory }}/:ro"
3
  - "/etc/localtime:/etc/localtime:ro"
4
  - "{{ '/etc/timezone:/etc/timezone:ro' if ansible_os_family == 'Debian' else '' }}"
5
  - "/lib/modules:/lib/modules:ro"
6
  - "/run/:/run/:shared"
7
  - "/dev:/dev"
8
  - "/sys/fs/cgroup:/sys/fs/cgroup"
9
  - "kolla_logs:/var/log/kolla/"
10
  - "libvirtd:/var/lib/libvirt"
11
  - "{{ nova_instance_datadir_volume }}:/var/lib/nova/"
12
  - "{% if enable_shared_var_lib_nova_mnt | bool %}/var/lib/nova/mnt:/var/lib/nova/mnt:shared{% endif %}"
13
  - "nova_libvirt_qemu:/etc/libvirt/qemu"
14
  - "{{ kolla_dev_repos_directory ~ '/nova/nova:/var/lib/kolla/venv/lib/python' ~ distro_python_version ~ '/site-packages/nova' if nova_dev_mode | bool else '' }
15
  - "/var/trilio:/var/trilio:shared"
Copied!
Next, find the variable nova_compute_default_volumes in the same file and append the mount bind /var/trilio:/var/trilio:shared to the list.
After the change will the variable look for a default Kolla installation as follows:
1
nova_compute_default_volumes:
2
  - "{{ node_config_directory }}/nova-compute/:{{ container_config_directory }}/:ro"
3
  - "/etc/localtime:/etc/localtime:ro"
4
  - "{{ '/etc/timezone:/etc/timezone:ro' if ansible_os_family == 'Debian' else '' }}"
5
  - "/lib/modules:/lib/modules:ro"
6
  - "/run:/run:shared"
7
  - "/dev:/dev"
8
  - "kolla_logs:/var/log/kolla/"
9
  - "{% if enable_iscsid | bool %}iscsi_info:/etc/iscsi{% endif %}"
10
  - "libvirtd:/var/lib/libvirt"
11
  - "{{ nova_instance_datadir_volume }}:/var/lib/nova/"
12
  - "{% if enable_shared_var_lib_nova_mnt | bool %}/var/lib/nova/mnt:/var/lib/nova/mnt:shared{% endif %}"
13
  - "{{ kolla_dev_repos_directory ~ '/nova/nova:/var/lib/kolla/venv/lib/python' ~ distro_python_version ~ '/site-packages/nova' if nova_dev_mode | bool else '' }}"
14
  - "/var/trilio:/var/trilio:shared"
Copied!
In case of using Ironic compute nodes one more entry need to be adjusted in the same file.
Find the variable nova_compute_ironic_default_volumes and append trilio mount /var/trilio:/var/trilio:shared to the list.
After the changes the variable will looks like the following:
1
nova_compute_ironic_default_volumes:
2
  - "{{ node_config_directory }}/nova-compute-ironic/:{{ container_config_directory }}/:ro"
3
  - "/etc/localtime:/etc/localtime:ro"
4
  - "{{ '/etc/timezone:/etc/timezone:ro' if ansible_os_family == 'Debian' else '' }}"
5
  - "kolla_logs:/var/log/kolla/"
6
  - "{{ kolla_dev_repos_directory ~ '/nova/nova:/var/lib/kolla/venv/lib/python' ~ distro_python_version ~ '/site-packages/nova' if nova_dev_mode | bool else '' }}"
7
  - "/var/trilio:/var/trilio:shared"

6] Pull TrilioVault container images
Pull the TrilioVault container images from the dockerhub based on the existing inventory file. In the example is the inventory file named multinode.
1
kolla-ansible -i multinode pull --tags triliovault
Copied!
7] Deploy TrilioVault
All that is left, is to run the deploy command using the existing inventory file. In the example is the inventory file named 'multinode'.  
This is just an example command. You need to use your cloud deploy command.
1
kolla-ansible -i multinode deploy

8] Verify TrilioVault deployment
Verify on the nodes that are supposed to run the TrilioVault containers, that those are available and healthy.

9] Troubleshooting Tips
9.1 ] Check TrilioVault containers and their startup logs
To see all TriloVault containers running on a specific node use the docker ps command.
1
docker ps -a | grep trilio
Copied!
To check the startup logs use the docker logs <container name> command.
1
docker logs trilio_datamover_api
2
docker logs trilio_datamover
Copied!
9.2] TrilioVault Horizon tabs are not visible in Openstack
Verify that the TrilioVault Appliance is configured. The Horizon tabs are only shown, when a configured TrilioVault appliance is available.
Verify that the TrilioVault horizon container is installed and in a running state.
1
docker ps | grep horizon

 10. Change the nova user id on the TrilioVault Nodes
Note: This step needs to be done on TrilioVault Appliance node. Not on OpenStack node.
Pre-requisite:
 You should have already launched TrilioVault appliance VM
In Kolla openstack distribution, 'nova' user id on nova-compute docker container is set to '42436'. The 'nova' user id on the TrilioVault nodes need to be set the same. Do the following steps on all TrilioVault nodes:
1.
Download the shell script that will change the user id
2.
Assign executable permissions
3.
Execute the script
4.
Verify that 'nova' user and group id has changed to '42436'
5.
After this step, you can proceed to 'Configuring Triliovault' section. 
1
## Download the shell script
2
$ curl -O https://raw.githubusercontent.com/trilioData/triliovault-cfg-scripts/master/common/nova_userid.sh
3
​
4
## Assign executable permissions
5
$ chmod +x nova_userid.sh
6
​
7
## Execute the shell script to change 'nova' user and group id to '42436'
8
$ ./nova_userid.sh
9
​
10
## Ignore any errors and verify that 'nova' user and group id has changed to '42436'
11
$ id nova
12
   uid=42436(nova) gid=42436(nova) groups=42436(nova),990(libvirt),36(kvm)
