Upgrades NodeBB's version to the one specified in environment.
For example, if your forum was created with NodeBB v1.12.1, you can use command like:
NODEBB_VERSION=latest nobbic upgrade my-new-forum
It will create a backup, stop current pod, remove it, restore from backup but using new version of NodeBB, and start it (including runnig NodeBB's upgrade procedure).
You can also override NODE_VERSION
, APP_USE_FQDN
(if you want to change also domain name), and/or any other options available for start
action.
