SSH & GUI with Docker for remote development
Preface
Docker is amazing.
This page gives a brief description on setting ssh in docker container for remote development and running gui apps in containers.
SSH into Docker Container for Remote Development
Just install openssh, config sshd_config and set envrionment variables, I did these works by running a script.
You may add this script to your dockerfile to produce image equipped with ssh service, for example:
FROM ubuntu:18.04
COPY ssh_for_remote_dev.sh /
RUN bash ssh_for_remote_dev.sh
...
Also, you may want to check my own dockerfile as here.
Notice: to make envrionment variables effective even if the bash is not running interactively, I add . ~/.bash_env in front of .bashrc, and I create a .bash_env file under $HOME. Just put your perosonal envrionment variables settings in .bash_env file.
Notice: run service ssh start everytime the container started, and set up the user for ssh, I use root by default.

CLion IDE does not resolve header files when use remote host
running GUI apps in container(macOS)
Actually, this way could be used widely only if your have browser and docker.
This is also quite easy by using novnc with docker compose, check here.
You can also copy following code and run a simple example.
# docker compose -f docker-compose.yml up -d
# open http://127.0.0.1:8080/vnc.html
# install and run gedit in your ubuntu container and you will see gedit in browser.
version: '3'

Just map X11 socket, I will record this later.
