I don’t have a docker app, so this may be needed, but I would assume a message would confirm this?
Curious to see if anybody has some thoughts on this.

joshua · May 10, 2022, 11:06am

Can you post the contents of the Dockerfile?

polygonjs · May 10, 2022, 11:50am

unfortunately I do not have any.
Should I then understand that this is a requirement?

joshua · May 10, 2022, 11:51am

It’s not a requirement, but if flyctl launch detects a Dockerfile (as you can see in the command output), it will deploy using that file. What does the output of ls look like in your lab/site directory?

polygonjs · May 10, 2022, 11:54am

I see. Looks like flyctl created it then. Here is the ls output:

OK, we’re getting further now! The first issue was an intermittent network error connecting to your remote builder VM.

Now you got connected, but the default version of Ruby is set to 2.7.3. To make it match your Gemfile, add this to your fly.toml:

[env]
   RUBY_VERSION = "3.0.3"

Then try fly deploy --remote-only. This is the command you’d use to deploy, normally. fly launch is just for the first time you setup an app.

Thank you. Although I seem to still have that same error. Here are the output as well as the content of the fly.toml.

the output:

Oops, my mistake! I need to document this

fly.toml should be:

[build]
  [build.args]
    RUBY_VERSION = "3.0.3"

polygonjs · May 10, 2022, 5:17pm

Looks like that worked!
Thanks a lot for your help.

I’ll now move to the next steps of my migration to fly.io and report back if I hit other issues.

Thanks a lot again

Great! I don’t think many people have used this Rails setup yet, so I’d love to hear how it goes. You can also configure your Node version, as you can see in the Dockerfile, in the same way.

polygonjs · May 10, 2022, 5:19pm

ah, what is unique about this rails setup? It’s very typical, at least to my knowledge.
Are there other best practices that you would recommend?

joshua · May 10, 2022, 5:34pm

By ‘setup’, I mean using a Dockerfile like this one to deploy. A lot of platforms will use the Ruby buildpack to deploy. This is fine, but we’ve found that it can be pretty bulky. A Dockerfile gives you some more control at the cost of being a bit more complex up front.

For I don’t recommend anything else specific. Just post here if you have any more issues.
