How to upgrade the OSM Platform

Upgrading the OSM platform

Due to the new architecture and dockerized components introduced from OSM Release FOUR, OSM platform upgrade is easier than ever. Upgrading to the latest minor version is as simple as running again the installer:

wget https://osm-download.etsi.org/ftp/osm-5.0-five/install_osm.sh
chmod +x install_osm.sh
./install_osm.sh

You will be asked if you want to proceed with the installation and configuration of LXD, juju, docker CE and the initialization of a local docker swarm, as pre-requirements. Please answer "y".

Then, some dialog messages related to LXD configuration will be shown. This is what you have to answer:

• Do you want to configure the LXD bridge? Yes
• Do you want to setup an IPv4 subnet? Yes
• << Default values apply for next questions >>
• Do you want to setup an IPv6 subnet? No

That's all. You will have the newest OSM version installed.

Upgrading the OSM platform from docker images using the latest daily docker image or a specific tag

Upgrading to the latest daily docker image might lead to potential issues. Moreover, every new re-deployment of the stack will involve a download of a new docker daily image if it exists. Unless you are really sure about what you are doing, please use this procedure with caution.

You can use option -t in the installer to specify a specific docker tag to be used by the installer.

To install the latest daily images:

./install_osm.sh -t releasefive-daily

To install a previous version e.g. v5.0.3:

./install_osm.sh -t v5.0.3

The previous commands will do the installation and deployment o the stack, but will not make it persistent after re-deployments of the stack. In order to make it persisten, you will have to update the file "docker-compose.yaml". Below an example to update it to use releasefive-daily tag:

sudo sed -i "s/ro\:\${TAG\:-latest}/ro\:\${TAG\:-releasefive-daily}/" /etc/osm/docker/docker-compose.yaml
sudo sed -i "s/lcm\:\${TAG\:-latest}/lcm\:\${TAG\:-releasefive-daily}/" /etc/osm/docker/docker-compose.yaml
sudo sed -i "s/mon\:\${TAG\:-latest}/mon\:\${TAG\:-releasefive-daily}/" /etc/osm/docker/docker-compose.yaml
sudo sed -i "s/pol\:\${TAG\:-latest}/pol\:\${TAG\:-releasefive-daily}/" /etc/osm/docker/docker-compose.yaml
sudo sed -i "s/nbi\:\${TAG\:-latest}/nbi\:\${TAG\:-releasefive-daily}/" /etc/osm/docker/docker-compose.yaml
sudo sed -i "s/light-ui\:\${TAG\:-latest}/light-ui\:\${TAG\:-releasefive-daily}/" /etc/osm/docker/docker-compose.yaml
sudo sed -i "s/keystone\:\${TAG\:-latest}/keystone\:\${TAG\:-releasefive-daily}/" /etc/osm/docker/docker-compose.yaml
docker stack rm osm && sleep 20
docker stack deploy -c /etc/osm/docker/docker-compose.yaml osm

The osmclient will have to be updated independently. In order to use the latest "testing" osmclient, you will have to update the debian repo to use the testing repo, remove the previous debian package and install the one from the new repo as follows:

sudo apt-get remove python-osmclient
sudo add-apt-repository -y "deb [arch=amd64] https://osm-download.etsi.org/repository/osm/debian/ReleaseFIVE-daily testing osmclient"
sudo apt-get update
sudo apt-get install python-osmclient
dpkg -l |grep python-osmclient   #to check the installed version

Upgrading a specific component to use your own cloned repo (e.g. for developing purposes)

Upgrading a specific OSM component without upgrading the others accordingly may lead to potential inconsistencies. Unless you are really sure about what you are doing, please use this procedure with caution.

For RO (ro and ro-db):

docker pull mysql:5

docker service update osm_ro --force --image opensourcemano/ro:develop
# In order to make this change persistent after reboots or restart of the docker stack
# you will have to update the file /etc/osm/docker/docker-compose.yaml to reflect the change
# in the docker image, for instance:
# sudo sed -i "s/ro\:\${TAG\:-latest}/ro\:\${TAG\:-develop}/" /etc/osm/docker/docker-compose.yaml

(OLD, CURRENTLY NOT WORKING) Upgrading only a specific component from source code to use the master branch or an old version (advanced users)

Upgrading a specific OSM component without upgrading the others accordingly may lead to potential inconsistencies. Unless you are really sure about what you are doing, please use this procedure with caution.

You can use options -b and -m in the installer:

./install_osm.sh --help
usage: ./install_osm.sh [OPTIONS]
Install OSM from binaries or source code (by default, from binaries)
 OPTIONS
...
    -b <refspec>:   install OSM from source code using a specific branch (master, v2.0, ...) or tag
                    -b master          (main dev branch)
                    -b v2.0            (v2.0 branch)
                    -b tags/v1.1.0     (a specific tag)
                    ...
    -m <MODULE>:    install OSM but only rebuild the specified docker images (RO, LCM, NBI, LW-UI, MON, KAFKA, MONGO, NONE)

Or to use master branch in LCM:

./install_osm.sh -m LCM -b master

Or to use an old version of MON:

./install_osm.sh -m MON -b tags/v5.0.2
