I have a dockerfile look like this
FROM ubuntu
MAINTAINER abc <abc.yur#gmail.com>
RUN apt-get update
RUN apt-get install nano
RUN apt-get install -y software-properties-common python-software-properties
RUN add-apt-repository ppa:longsleep/golang-backports
RUN apt-get update
RUN apt-get -y install golang-go git
RUN mkdir /work
ENV GOPATH=/work
RUN go get github.com/abc/golang
RUN go build github.com/abc/golang
CMD /golang -addr $ADDR -workers $WORKERS
So I want to build and run container but after the building (docker build .) I can not run this container. So when I am running docker ps -a or docker ps there is not container to run
docker build .
This creates the image and not a container. You need to use
docker images
To get the list of images.
docker ps will show when you run a container using something like below
docker run -d <image>

Hello I created a base image; however, whenever I run the docker build ., I don't see the successfully built
My docker file

ARG home=/home/$user
RUN yum update -y
RUN yum install openssh-server -y
RUN yum install openssh-clients -y

Your container includes systemd which will not run under this circumstances.

EXPOSE 8080
RUN /usr/local/tomcat/apache-tomcat-8.5.61/bin/catlina.sh run
Created Docker image for the respective docker file using:
docker build -t [filename] .

I had created the Docker container for RabbitMQ using the Following Docker File, But not able to run the Container, It's automatically stops.
Docker File
FROM centos:centos7
RUN yum -y update
RUN yum -y install wget
RUN wget https://www.rabbitmq.com/releases/erlang/erlang-18.2-1.el6.x86_64.rpm
RUN yum -y install erlang-18.2-1.el6.x86_64.rpm
RUN wget https://www.rabbitmq.com/releases/rabbitmq-server/v3.6.9/rabbitmq-server-3.6.9-1.el7.noarch.rpm
RUN yum -y install rabbitmq-server-3.6.9-1.el7.noarch.rpm
EXPOSE 15672
EXPOSE 5672
RUN rabbitmq-plugins enable rabbitmq_management
CMD /usr/sbin/rabbitmq-server -detached
Docker build Command
docker build -t rabbit .
Docker run command
docker run -d -p 15672:15672 rabbit
Container starts but's its exit's after a second
Thanks in advance
If I run my Dockerfile with the following command, the docker container starts running and all is well.
docker run --name test1 -i -t 660c93c32a
However, if I run this command without the -it, the container does not appear to be running as docker ps returns nothing:
docker run -d --name test1 660c93c32a
.
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS
PORTS NAMES
All I'm trying to do is run the container and then be able to attach and/or open a shell in the container later.
Not sure if the issue is in my dockerfile or not, so have pasted the dockerfile below.

When you run your container, command after CMD or ENTRYPOINT becomes $1 process of you container. If this process doesn't run well, your container will die.
So, check container logs using: docker logs <container id>
and recheck your command in CMD django-admin startproject $PROJECTNAME
I'm trying to create a VM with docker and boot2docker. I've made the following Dockerfile, which I'm trying to run through the command line
docker run Dockerfile
Immidiatly it says exactly this:

I am in the directory where the Dockerfile is, when trying to run this command.
Ignore the zip part, as that's for later use
You should run docker build first (which actually uses your Dockerfile):
docker build --tag=imagename .
Or
docker build --tag=imagename -f yourDockerfile .
Then you would use that image tag to docker run it:
docker run imagename
There are tools that can provide this type of feature.
We have achieved using docker compose, though you have to go through
(https://docs.docker.com/compose/overview/)
docker-compose up
but you can also do as work around
$ docker build -t foo . && docker run foo.
