OK two things:
first - when you run the container with the /bin/sh command in the end that's the command the container is running, not your web app.
See your used docker image dockerfile and ENTRYPOINT and CMD commands.
when you add the command in the end of the docker run command you override the preconfigured startup commands:
Usage: docker run [OPTIONS] IMAGE [COMMAND] [ARG...]
For that run docker run -dp 60:60 jenkins_php:latest
example with nginx:
when running like suggested in question:
docker run -itdp 80:80 nginx /bin/sh
We get trying to access through chrome:
when running "regularly" with:
docker run -dp 80:80 nginx
or even
docker run -itdp 80:80 nginx
We get trying to access through chrome:
and in either case when running docker ps it doesn't show the new command but the old entry-point script (just like in the question) even though it was overridden:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3fe92585a40c nginx "/docker-entrypoint.…" 3 seconds ago Up 2 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp adoring_heisenberg
second - it is also possible that after fixing that it wont work cause you also publish port 80/tcp and unless you specifically chose that it would make more sense to publish on 80 by default so I'd check that along the way.
for that run docker run -dp 80:80 jenkins_php:latest
if we try to replicate like in the previous misconfiguration we get the same error
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
