Heroku deployment #180

Closed bitcoinminersuk closed 4 years ago

I am trying to deploy a Cryogen site to heroku and I am getting the following errors in the logs

loading module: Markdown parser 2019-05-07T01:12:11.270230+00:00 heroku[web.1]: State changed from starting to crashed 2019-05-07T01:12:11.168013+00:00 app[web.1]: compiling assets... 2019-05-07T01:12:11.168505+00:00 app[web.1]: Error: Not a file: jar:file:/app/target/cryogen-standalone.jar!/templates/config.edn 2019-05-07T01:12:11.168863+00:00 app[web.1]: "Elapsed time: 0.990418 msecs" 2019-05-07T01:12:11.250187+00:00 heroku[web.1]: Process exited with status 0 2019-05-07T01:12:27.364291+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=jimmymothy.herokuapp.com request_id=09602c38-9626-4270-9368-b14266d5973c fwd="82.102.19.198" dyno= connect= service= status=503 bytes= protocol=https

The project.clj is as follows:

`(defproject cryogen "0.1.0" :description "Simple static site generator" :url "https://github.com/lacarmen/cryogen" :license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} :dependencies [[org.clojure/clojure "1.10.0"] [ring/ring-devel "1.7.1"] [compojure "1.6.1"] [ring-server "0.5.0"] [cryogen-markdown "0.1.9"] [cryogen-core "0.1.67"]] :plugins [[lein-ring "0.12.5"]]

:min-lein-version "2.0.0"

:uberjar-name "cryogen-standalone.jar"

:main cryogen.core :ring {:init cryogen.server/init :handler cryogen.server/handler})`

and I have the procfile as I was advised (I have tried a few variations but still get the same error):

web: java $JVM_OPTS -cp target/cryogen-standalone.jar clojure.main -m cryogen.core

I would be grateful for any help and once I have it working I should be able to help put a small guide for others that wish to use heroku.

Cheers

Jim

Are you trying to run the actual cryogen project on Heroku or just deploy the static content?

Apologies for the delayed reply, I am trying to run it on heroku

If you are running the project from a jar then it won't be able to read the config file. This error comes from this function when it's called by read-config.

io/resource returns a URL, and when running with lein the URL happens to be a file:// URL so io/file can accept it. However, once the resource is in a jar that is no longer the case.

You might be able to get it to work by removing the call to io/file from that function but find-assets also uses get-resource and I don't know if that will cause issues. If you're looking to host your site it's much better to generate the assets and host the statically rather than keeping the project running.
