Question: If I have a Docker file that has at the end:

```
ENTRYPOINT /bin/bash

```

and run the container via `docker run` and type in the terminal

```
gulp

```

that gives me running gulp that I can easily terminate with `Ctrl+C`

but when I put `gulp` as default command to `Dockerfile` this way:

```
CMD ["/bin/bash", "-c", "gulp"]

```

or this:

```
ENTRYPOINT ["/bin/bash", "-c", "gulp"]

```

then when I run container via `docker run` the `gulp` is running but I can't terminate it via `Ctrl+C` hotkey.

The Dockerfile I used to build the image:

```
FROM node:8

RUN apt-get update \
    && apt-get upgrade -y \
    && apt-get install -y libltdl-dev

WORKDIR /home/workspace

RUN npm install gulp -g

#works but cant kill gulp with Ctrl+C
#CMD ["/bin/bash", "-c", "gulp"]

#works but cant kill gulp with Ctrl+C
#ENTRYPOINT ["/bin/bash", "-c", "gulp"]

# need to type command gulp in cli to run it
# but I'm able to terminate gulp with Ctrl+C
ENTRYPOINT /bin/bash

```

It makes sense to me I can't terminate the default command for the container that is defined in Dockerfile because there would be no other command that could run once I terminate the default.

How can I state in Dockerfile that I want to run `/bin/bash` as default and on top of that `gulp` so If I terminate `gulp` I'll be switched back to the `bash` command line prompt?

Answer: 
I use [tiles](https://bulma.io/documentation/layout/tiles/) when I do something similar.  

Not shorter, but you don't have to worry about `.columns`

You need to limit the horizontal size of the colum divs using modifiers. There are many ways to do so. Here is one:

```
<div class="container">
  <div class="columns is-tablet">
    <div class="column is-half">
      <span>adress</span>
    </div>
   <div class="column is-half">
      <span>city</span>
    </div>
  </div>
  <div class="columns is-tablet">
    <div class="column is-half">
      <span>phone</span>
    </div>
    <div class="column is-half">
      <span>email</span>
    </div>
  </div>
</div>

```
