我从docker（https://hub.docker.com/_/couchdb）处获取了沙发床图像，然后运行以下命令：
docker run -p 5984:5984 -d --name my-couchdb2 couchdb:latest
docker commit 1d329ef7c516 registry.heroku.com/coucherte/web
docker tag my-couchdb2 registry.heroku.com/coucherte/web
docker push registry.heroku.com/coucherte/web
heroku container:release web --app coucherte
在此之后，dyno崩溃了，并显示“ heroku logs --app coucherte”：

我做错了什么？我该如何更改Heroku的端口？使用Heroku时是否需要更改沙发床设置才能使用HTTPS？
更新
我现在发现根目录下的映像中有一个名为docker-entrypoint.sh的文件。在此文件中有以下行：
find /opt/couchdb \! \( -user couchdb -group couchdb \) -exec chown -f couchdb:couchdb '{}' +
所以在这一行上，我认为它在heroku中崩溃了。因此，用户ouchdb存在问题。它在本地有效，我可以通过以下方式找到用户：
cut -d: -f1 /etc/passwd
但是在heroku上，该用户不存在或找不到。为什么？
