问题
I few days ago I was trying to deploy a docker image of a spring boot app into heroku.
I have the following docker file:
FROM openjdk:8-jdk-alpine
LABEL maintainer="gabigarciagar@gmail.com"
VOLUME /tmp
COPY ./target/*.jar PetApp_Auth.jar
CMD [ "java","-Xmx300m","-Xss512k","-XX:CICompilerCount=2","-Dfile.encoding=UTF-8","-Dspring.profiles.active=heroku","-Djava.security.egd=file:/dev/./urandom","-jar","/PetApp_Auth.jar" ]
also in my application.properties for a heroku profile i have:
spring.profiles.active=heroku
server.port=${PORT}
server.servlet.context-path=/
then i execute the following commands and everithig looks nice:
$ heroku container:push petapp-authserver -a petapp-authserver
Your image has been successfully pushed. You can now release it with the 'container:release' command.
$ heroku container:release petapp-authserver -a petapp-authserver
Releasing images petapp-authserver to petapp-authserver... done
Also the heroku log show that the app is up and also heroku ps the database connection is perfect also
$ heroku ps -a petapp-authserver
=== petapp-authserver (Free): java -Xmx300m -Xss512k -XX:CICompilerCount\=2 -Dfile.encoding\=UTF-8 -Dspring.profiles.active\=heroku -Djava.security.egd\=file:/dev/./urandom -jar /PetApp_Auth.jar (1)
petapp-authserver.1: up 2020/03/06 21:09:51 +0100 (~ 1m ago)
Then when i try to see swagger-ui o /actuator/health i get the following:

as heroku web said https://devcenter.heroku.com/articles/error-codes#h14-no-web-dynos-running
i execute:
heroku ps:scale petapp-authserver=1 -a petapp-authserver
Scaling dynos... done, now running petapp-authserver at 1:Free
And same error
What I am doing wrong??
I was able to deploy the jar directly and it works
heroku deploy:jar PetApp_AuthServer-V-0.0.0.jar -a petapp-authserver

Why it perfecty works with jar deploy and not with docker??
I have also tried:
Gabi@MSI MINGW64 /d/Proyectos/PetApp/Back/PetApp_AuthServer (develop)
$ heroku container:release web petapp-authserver -a petapp-authserver
! Expected response to be successful, got 404
Gabi@MSI MINGW64 /d/Proyectos/PetApp/Back/PetApp_AuthServer (develop)
$ heroku container:release web petapp-authserver -a petapp-authserver
! Expected response to be successful, got 404
Gabi@MSI MINGW64 /d/Proyectos/PetApp/Back/PetApp_AuthServer (develop)
$ heroku container:release petapp-authserver -a petapp-authserver
Releasing images petapp-authserver to petapp-authserver... done
Thanks in advance
回答1:
Finally I solved the question. The point is that the image in heroku must be named same as the process type, in this case web!
so there are two options. Build and pushing the image by using:
heroku container:push web -a petapp-authserver
or create the image locally and the tag it as registry.heroku.com/petapp-authserver/web
docker tag petapp-authserver registry.heroku.com/petapp-authserver/web
docker push registry.heroku.com/petapp-authserver/web
The push refers to repository [registry.heroku.com/petapp-authserver/web]

heroku container:release web -a petapp-authserver

Now my containers are perfectly running in docker!!
Thank you all

In your Procfile or your heroku.yml you have not specified a web worker.
2020-03-06T20:12:23.878827+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=GET path="/favicon.ico" host=petapp-authserver.herokuapp.com request_id=f83acdef-840a-4e2e-824c-183cfdc50273 fwd="79.147.107.220" dyno= connect= service= status=503 bytes= protocol=http
For containers you should use heroku.yml. Procfile might even be ignored.
https://devcenter.heroku.com/articles/build-docker-images-heroku-yml
Doing this will get rid of your current H14 errors.

Key point is the process type.
For example, when you deploy the jar and runs it, you can see at your logs:
remote: -----> Discovering process types
remote: Procfile declares types -> web
But you don't see it when using release because you haven't specified a process type. Can you try to run the release command like this and see if it works?
heroku container:release web petapp-authserver -a petapp-authserver
web is the process type!
