Installation and used Fenics in docker

Hi,
I want to use Fenics-dolfinx with docker but I have a problem when I install it by using the following instructions :slight_smile: A Docker image with DOLFINx built nightly:

docker run -ti dolfinx/dolfinx:latest

To switch between real and complex builds of DOLFINx.

source /usr/local/bin/dolfinx-complex-mode
source /usr/local/bin/dolfinx-real-mode

A Jupyter Lab environment with DOLFINx built nightly:

docker run --init -ti -p 8888:8888 dolfinx/lab:latest # Access at http://localhost:8888

A development image with all of the dependencies required to build DOLFINx:

docker run -ti dolfinx/dev-env:latest

Can you please give me the steps to install it and start with an example?

Best regards.

Im not really sure what you are asking for here.
The instructions how you the different ways of accessing DOLFINx through docker.

What issue exactly are you having with these commands?
