First we go create account in docker-hub, when we have a account, login with this account in the computer

sudo docker login --username=your_user_name

create the repository

https://hub.docker.com/repository/create

mkdir -p ubuntu-ssh && cd ubuntu-ssh

add file to build image

touch Dockerfile

open file with your editor favorite, i use vim :)

vim Dockerfile

add this content

FROM ubuntu:18.04


# disable interactive functions
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update
RUN apt-get install -y software-properties-common
RUN apt-get install ssh -y


CMD ["bash"]

if you use vim, to save and exit press : and write wq and press ENTER

build the image local

sudo docker build . -t ubuntu-ssh

list images

sudo docker images

we create a tag of image

sudo docker tag e53082e90e87 your_user_name/ubuntu-ssh:latest

we push the image

sudo docker push your_user_name/ubuntu-ssh:latest

it is done, the image is ready in docker hub how this image https://hub.docker.com/r/cirelramos/ubuntu-ssh

spectacle -r -c -b

 sudo vim /etc/pulse/default.pa

you can append auto_switch=2 to load-module module-bluetooth-policy
