My host machine application is trying to establish a SCTP connection at port 38412 to a docker container which is running SCTP server at port 38412. I am mapping and publishing the ports but getting an error. My host application is timing out at the following check:
if (connect(fd, (struct sockaddr*)&myaddr,sizeof(myaddr))== -1){
higLog("SCTP CLIENT connect failed, port %d, Error %s",
port, strerror(errno));
return -1;
}
Error Connection timed out
My DockerFile looks something like this.

And running this container using the following docker-run command:
docker run --name con1 --net Network1 --ip 10.0.0.21 -p 127.0.0.1:38412:38412/sctp sourav/image1:1.0.0
Can I get some ideas on how to solve it ?

When I am using the elasticsearch official docker image ELASTIC_PASSWORD env variable is working good
docker run -dti -e ELASTIC_PASSWORD=my_own_password -e discovery.type=single-node elasticsearch:7.8.0
But when I build my own customized docker image the ELASTIC_PASSWORD is not working can you please help me on this
Here is my Docker file

As I think in order to achieve this functionality (set ELASTIC_PASSWORD from command line and it works) for your own container you need to re-configure Elasticsearch startup script. It's not a trivial task.
For example here is docker-entrypoint.sh from official docker image.
https://github.com/elastic/elasticsearch/blob/master/distribution/docker/src/docker/bin/docker-entrypoint.sh
You can see that script do all 'hidden' work to allow us to run it by only command.

However when I try to run this on Ubuntu I get X11 errors from the Pycharm code:
Start Failed: Failed to initialize graphics environment
java.awt.AWTError: Can't connect to X11 window server using ':1' as
the value of the DISPLAY variable. at
java.desktop/sun.awt.X11GraphicsEnvironment.initDisplay(Native Method)
The command to invoke the container is:
docker run -it --rm -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=${DISPLAY} <<image_id>>
I have tried many variations on the DISPLAY var (eg unix$DISPLAY), but none have worked.
Update:
I ran:
docker run -it --rm -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=${DISPLAY} --entrypoint /bin/sh <<image_id>>
to get access into the container, and then ran:
$ ls -l /tmp
total 0
I am confused - I thought the X11 socket residing in my host machine would have been bound to the same location in the container. Is this a red-herring?
I am trying to run riofs inside a docker container, however when I try to run riofs I get the following error:

I needed to add the runtime privilege SYS_ADMIN because fuse needs permissions to mount/umount.
docker run -it --cap-add SYS_ADMIN --device /dev/fuse [IMAGE] bash
You can use EXPOSE in Docker for:
The EXPOSE instructions informs Docker that the container will listen
on the specified network ports at runtime.
Can I do the opposite? Can I expose port from my Ubuntu to the docker container?
Background: I'm trying to setup a simple php7-fpm as a docker image and I would like to expose port 3306 (MySQL service) to the docker container.

I am trying to build an nginx image for installing nginx with the Module ngx_http_auth_request_module.
this is my current docker file:
#ubuntu OS
FROM ubuntu:14.04
#update apt-get non interactive and install nginx
RUN \
sudo apt-get -q -y update; \
sudo apt-get -q -y install nginx
#copy all mapping configurations for all environments
COPY ./resources/routing-configs/* /routing-configs/
#expose port for nginx
EXPOSE 80
#run task to copy only relevant mapping configuration to nginx and reload nginx service
COPY ./resources/start.sh /opt/mysite/router/start.sh
RUN sudo chmod 766 /opt/mysite/router/start.sh
CMD sudo -E sh /opt/mysite/router/start.sh
typically i would have compiled the nginx files locally like this:
sudo ./configure --with-http_auth_request_module
and then install nginx
sudo make install
but how can i do this with docker file?
please help
