我目前正在将我的 Discourse 论坛从一台服务器迁移到另一台服务器。两台服务器都运行 Linux CentOS 7.9。
我已按照使用 ./launcher bootstrap app 来引导应用程序的步骤进行操作，但遇到了以下错误：
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'
...
看起来 Docker Manager 插件和 handlebars 模板存在问题。我不确定如何继续并解决此错误。有人能指导我如何修复吗？
与此同时，我决定将 local_discourse/app 镜像从原始服务器复制到新服务器。我使用了 ./launcher start app 来启动应用程序，但遇到了另一个错误：
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) }
...
看起来 Pups 配置与 env_template、env、labels 和 params 键有关。此错误阻止应用程序正常启动。
我感到很卡住，不知道如何继续。如果有人在 Discourse 迁移或应用程序启动过程中遇到类似问题，我将非常感谢您的帮助。如果您有任何建议或解决方案，请告诉我。
提前感谢您的帮助！
