issues with deployment.

[TwistingTwists]

after I do fly deploy

I get

Changed a few elixir and node versions

see : TwistingTwists@d2097ea

[dbernheisel]

I'll try bumping the Node and Elixir versions and see if I have an issue deploying. I have a github action to automatically deploy to fly, so I'll see the results there.

[dbernheisel]

It looks like the Dockerfile might have also changed:

Looking at this:

=> CACHED [builder  9/17] RUN mix deps.compile                                                                                         0.0s
 => CACHED [builder 10/17] COPY priv priv                                                                                               0.0s
 => CACHED [builder 11/17] COPY assets assets                                                                                           0.0s
 => [builder 12/17] RUN mix assets.deploy            

There should be a couple more steps after copying assets over before running mix assets.deploy, like running npm ci

Can you verify you didn't adjust the Dockerfile?

[dbernheisel]

Ah, I think Fly uses a default Dockerfile when one is not present, and it seems you renamed Dockerfile to Dockerfile.old. You'll need to keep the Dockerfile intact.

[TwistingTwists]

Ah. I thought I might need a new Dockerfile for deployment.

Thanks for pointing out!

[TwistingTwists]

for commit history see : https://github.com/TwistingTwists/til-phoenix-blog/commits/main

Mostly css changes. Nothing changed in deployment or assets/js

[TwistingTwists]

in runtime.exs

if config_env() == :prod do
  System.get_env("AUTH_USER") ||
    System.get_env("AUTH_PASS") ||
    raise "environment variable AUTH_USER and/or AUTH_PASS is missing."

which causes app to crash on fly

[TwistingTwists]

How do you set those variables on fly?

[TwistingTwists]

fly secrets set

done.

[TwistingTwists]

Wohoo! It is live at https://abhishek.fly.dev/

Thank you so much!
