I don’t have a docker app, so this may be needed, but I would assume a message would confirm this?
Can you post the contents of the Dockerfile?
unfortunately I do not have any.
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?
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.

Looks like that worked!
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.
ah, what is unique about this rails setup? It’s very typical, at least to my knowledge.
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.

Hello again,
I’ve decided to try and deploy the same app with Docker only, to better understand how that could simplify the deploy process. And while I can run the docker container in my local machine, I’ve hit a couple issues on fly.io . Let me know if you’d prefer me to open a new thread, but in the mean time, here are the problems:
curl https://polygon-lab-docker-test.fly.dev/
curl: (56) OpenSSL SSL_read: error:0A000126:SSL routines::unexpected eof while reading, errno 0
and the log is:
$ fly logs -a polygon-lab-docker-test
Waiting for logs...

I’m unfortunately not sure where to look to understand what Error 2011: App is unhealthy is referring to.
And here is the Dockerfile, which I’ve rewrote from scratch (it’s very likely I removed something I should not)
# syntax=docker/dockerfile:1
FROM ruby:3.1.2
RUN apt-get update -qq && apt-get install -y nodejs postgresql-client
WORKDIR /myapp
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN gem install bundler
RUN bundle install
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list
RUN apt update && apt install yarn
COPY . /myapp
RUN yarn install --ignore-engines --force
ENV RAILS_ENV=production
ENV SECRET_KEY_BASE=redacted
ENV RAILS_SERVE_STATIC_FILES=1
RUN bin/rails assets:precompile
COPY . /myapp
# Add a script to be executed every time the container starts.
COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 3000
# Configure the main process to run when running the image
# CMD ["rails", "server", "-b", "0.0.0.0"]
CMD ["bundle", "exec", "puma", "-C", "config/puma.rb"]
and entrypoint.sh:
#!/bin/bash
set -e
# Remove a potentially pre-existing server.pid for Rails.
rm -f /myapp/tmp/pids/server.pid
#!/bin/bash
# bundle install --jobs 20 --retry 5
# Then exec the container's main process (what's set as CMD in the Dockerfile).
exec "$@"
Is that enough information for you to help debugging this? Let me know if there is more I should share here.

I have similar problem. RUBY_VERSION is “3.1.2” and this is the error message I have when I run fly deploy:
Error failed to fetch an image or build from source: error building: executor failed running [/bin/bash -c bin/rails fly:build]: exit code: 1

Can you give us more information? Is this using a custom docker image or a buildpack?
Can you try Build images with nixpacks ?

Okay, let me try that and get back to you on this.

I got this error when I tried to build images with nitpicks
Error: Please install Docker to build the app https://docs.docker.com/engine/install/
Error failed to fetch an image or build from source: exit status 1
I’m using a Mac please.
