How to deploy?

[phortx]

I'm currently trying to deploy my Rails app with ember-cli-rails. I've got a frontend/ directory containing the ember app.

My deploy process before ember was:

• Run bundle exec rails assets:precompile RAILS_ENV=production locally
• Upload public/assets
• Update app on the server
• Restart server

That worked like a charm.

As far as I understood should rails assets:precompile precompile the ember assets too via ember build. But the compiled app will be put into the /tmp directory. Is that correct?

I've tried to move the files from tmp/ember-cli/apps/ to public/ but still getting the error EmberCLI failed to generate an index.html file on the server at the first request.

Can you help me?

Thanks for the fast response! I've updated the issue description.

Do you have any hint how to fix that issue?

The deployment process that ember-cli-rails works best with out of the box depends on the asset compilation happening on the server itself.

For instance, when deploying to Heroku, ember-cli-rails hooks into the rake assets:precompile task to generate its assets, so that they can be included in the slug that is deployed to the dynos.

The same is true for Capistrano, where the servers run rake assets:precompile locally.

If the EmberCLI asset compilation occurs locally on your development machine, you should consider other EmberCLI deployment strategies.

The EmberCLI Deploy project is a collection of such strategies.

The only deployment strategy that ember-cli-rails integrates at this time is the Redis-backed "Lightning" strategy. If you're interested in using this deployment strategy, check out the ember-cli-rails-deploy-redis gem.

If you decide to use another deployment strategy that isn't yet supported by ember-cli-rails, please open an issue, and we can decide how to proceed.

Alternatively, is it possible to move the asset compilation onto the servers themselves?

Thank you very much for you comprehensive answer! We had some troubles with compiling the assets on the server, however I'll try to get that running and tell you if it worked :)

[seanpdoyle]

I'll close this issue for now.

Have you had any success with incorporating the feedback in https://github.com/thoughtbot/ember-cli-rails/issues/505#issuecomment-267629756?

If not, please share some of your issues and I'll reopen this.

Sorry for the late response ... I was too busy lately to focus on our deployments.

I've tried to move the asset compilation to the server, that works.

Thank you very much, for your time and help! <3

However: Locally precompiling have to be possible soon, to reduce downtime while deploying and to enable the usage of a CDN and so on.
