"heroku container:release -a docker-nodejs-app web", instead of "heroku container:push web". -> for release part

"heroku container:push -a docker-nodejs-app web" works for me, instead of "heroku container:push web".

run "docker run -p 3000:3000 docker_nodejs_app" instead of "docker run -it docker_nodejs_app" solve my problem. :) also, "EXPOSE 3000:3000" in Dockerfile - didnt work, and should be just: "EXPOSE 3000"

run "docker run -it docker_nodejs_app" in terminal, but when going to http://localhost:3000/ from the browser, i got the error: "This site can't be reached" help?
