4 years ago Just some term clarification:
- You do not download a container. Instead you are dowloading an image. In terms of Docker you are pulling an image.
- With
docker run IMAGENAMEyou are starting a container from an image. - A docker image can be seen as an immutable base. (Unless you change the Dockerfile and build the image again.)
- With
docker runyou are starting a container. The container contains the image; but all changes are done in a separate layer and do not touch the image itself.
Where I can watch downloaded containers through x11docker? Is there something like a docker ps -a ?
x11docker uses Docker and its commands docker pull and docker run. x11docker images are not different from Docker images, it is entirely the same.
- You can see local images with
docker images- You can see current active containers with
docker ps - x11docker always starts a fresh container from an image and discards it afterwards. It does not use the possibility to reuse an old container.
- You can see current active containers with
Is it possible to run image which was downloded by docker?
Yes.
Is it possible to create custom image for x11docker?
Yes. You can look at my repositories for some examples. Short example for a Dockerfile:
FROM debian:buster
RUN apt-get update
RUN apt-get install -y xterm
CMD xtermBuild:
docker build -t myxtermimage PATH/TO/DOCKERFILERun:
x11docker myxtermimageYou can look in image list:
docker images | grep xtermYou can look at containers while xterm is running:
docker ps What may need for this (it should be able to run OpenGL/Vulkan application)?
Probably it is enough to install the open source MESA drivers in image / in the Dockerfile and to run x11docker with option --gpu. Compare Dependencies in image for option --gpu.
RUN apt-get install -y mesa-utils mesa-utils-extra

Hello.
I have some questions about working with x11docker's images and containers:
docker ps -a?Thanks!
