I’m currently in the process of migrating my Discourse forum from one server to another. Both servers are running Linux CentOS 7.9.
I have followed the steps to bootstrap the app using ./launcher bootstrap app, but I encountered the following error:
I, [2023-06-17T17:15:58.122571 #1] INFO -- : > cd /var/www/discourse && su discourse -c 'LOAD_PLUGINS=0 bundle exec rake plugin:pull_compatible_all'
I, [2023-06-17T17:16:00.306019 #1] INFO -- : docker_manager is already at latest compatible version
I, [2023-06-17T17:16:00.307142 #1] INFO -- : > cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate'
rake aborted!
[docker_manager] Handlebars templates can no longer be included via `register_asset`.
Any hbs files under `assets/javascripts` will be automatically compiled and included."
/var/www/discourse/lib/plugin/instance.rb:638:in `register_asset'
...
It seems that there is an issue with the Docker Manager plugin and the handlebars templates. I’m not sure how to proceed and resolve this error. Could someone please guide me on how to fix this?
In the meantime, I decided to copy the local_discourse/app image from the original server to the new server. I used ./launcher start app to start the application, but I encountered another error:
I, [2023-06-18T11:24:51.537970 #1] INFO -- : Reading from stdin
/usr/local/lib/ruby/gems/3.2.0/gems/pups-1.1.1/lib/pups/config.rb:14:in `block in initialize': undefined method `has_key?' for nil:NilClass (NoMethodError)
['env_template', 'env', 'labels', 'params'].each { |key| @config[key] = {} unless @config.has_key?(key) }
...
It seems that there is an issue with the Pups configuration related to the env_template, env, labels, and params keys. This error is preventing the app from starting properly.
I’m feeling stuck and unsure about how to proceed. If anyone has encountered similar issues during Discourse migration or app startup, I would greatly appreciate your assistance. Please let me know if you have any suggestions or solutions.
