Rolling upgrade on Kolla Openstack

Upgrade tvault-datamover-api package (trilio_datamover_api Container)

Container trilio_datamover_api needs to be redeployed. Follow below steps on all controller nodes :

  • Backup Existing conf files/folders

Copy folders /etc/kolla/nova-api & /etc/kolla/trilio-datamover-api/ to some local location.
Eg. cp -r /etc/kolla/nova-api $HOME/4.0-BK/

  • Stop and Remove existing container trilio_datamover_api

docker stop trilio_datamover_api
docker rm trilio_datamover_api

  • Pull trilio_datamover_api container image:

## Login to docker using credentials: triliodocker/triliopassword
docker login docker.io

## Pull Trilio Datamover Api container using following command. You need to edit OS_PLATFORM, TVAULT_VERSION,
 OPENSTACK_RELEASE_NAME.

<OS_PLATFORM> could be ubuntu/centos.
<OPENSTACK_RELEASE_NAME> could would be train
<TVAULT_VERSION>    : For exact GA build version check section 1. i) Plan for deployment

docker pull docker.io/trilio/<OS_PLATFORM>-source-trilio-datamover-api:<TVAULT_VERSION>-<OPENSTACK_RELEASE_NAME>

Example command for train openstack on ubuntu platform with triliovault 4.0 release:
docker pull docker.io/trilio/ubuntu-source-trilio-datamover-api:4.0.106-train

  • Run datamover api container.

You need to edit OS_PLATFORM, TVAULT_VERSION, OPENSTACK_RELEASE_NAME. 
<OS_PLATFORM> could be ubuntu/centos.
<OPENSTACK_RELEASE_NAME> would be train
<TVAULT_VERSION> : For exact TVAULT build version check section 1. i) Plan for deployment

docker run --network host --name trilio_datamover_api -d --restart always -v /etc/kolla/trilio-datamover-api/nova.conf:/etc/nova/nova.conf \
-v /etc/kolla/trilio-datamover-api/dmapi.conf:/etc/dmapi/dmapi.conf \

trilio/<OS_PLATFORM>-source-trilio-datamover-api:<TVAULT_VERSION>-<OPENSTACK_RELEASE_NAME> /var/lib/kolla/venv/bin/python /usr/bin/dmapi-api

  • Verify deployment

Make sure 'trilio_datamover_api' named container running well and not in 'restarting' state on all controller nodes. 
'docker ps' command can be used for the same.

# docker ps | grep trilio_datamover_api

Upgrade Horizon Plugin Package

  • Login to horizon container (on controller node)

docker exec -it horizon /bin/bash

  • Add gemfury repo on horizon to get updated packages.

    Create a file /etc/apt/sources.list.d/fury.list and add below line in it.

    deb [trusted=yes] https://apt.fury.io/triliodata-4-0/ /

    Use below commands to get list of updated packages available on repo's.

    apt-get update
apt list --upgradable

  • For Horizon plugin upgrade, following packages need to be upgraded.

python3-tvault-horizon-plugin python3-workloadmgrclient

Note: If your cloud does not use 'ceph' storage for nova/cinder, remove '/etc/ceph' volume mount option 
from below commands.

##If backup storage type is 'NFS'
docker run --privileged --network host --name trilio_datamover -d \
--restart always \
