Image Build

1.1 Start Development Environment​

Create a non-INSPIR official container image via Dockerfile or by pulling an external image.
For example: docker pull nvcr.io/nvidia/pytorch:21.07-py3
image
Use this container image to create a development environment and log in to the Shell terminal.

1.2 Install Components​

This document provides instructions for installing Jupyter and SSH components in an Ubuntu 20.04 environment. Python version requirement: >3.0 JupyterLab version: 2.3.1 SSH version: OpenSSH_8.2p1

1.3 Install from Public Mirrors​

Note: JupyterLab must be installed before SSH; otherwise, the Jupyter page may fail to open.

1.3.1 Install Python​

Execute the installation command to update the apt package mirror and install Python 3.

apt-get update && apt-get install python3-pip

1.3.2 Install JupyterLab​

Execute the installation command to install Jupyter.

pip --no-cache-dir install jupyterlab==2.3.1 -i  https://pypi.tuna.tsinghua.edu.cn/simple

Download the Jupyter configuration file and place it in the /etc/jupyter/ directory.

mkdir /etc/jupyter/
wget –P /etc/jupyter/https://raw.githubusercontent.com/Winowang/jupyter_gpu/master/jupyter_notebook_config.py 
wget -P /etc/jupyter/ https://raw.githubusercontent.com/Winowang/jupyter_gpu/master/custom.js

1.3.3 Install SSH​

Install openssh-client and openssh-server, and create the /var/run/sshd directory.

apt-get install -y --no-install-recommends openssh-client openssh-server && mkdir -p /var/run/sshd

Modify the configuration to allow direct SSH login to the container.

cat /etc/ssh/ssh_config | grep -v StrictHostKeyChecking > /etc/ssh/ssh_config.new
echo "    StrictHostKeyChecking no" >> /etc/ssh/ssh_config.new
cat /etc/ssh/sshd_config | grep -v  PermitRootLogin> /etc/ssh/sshd_config.new
echo "PermitRootLogin yes" >> /etc/ssh/sshd_config.new
mv /etc/ssh/ssh_config.new /etc/ssh/ssh_config
mv /etc/ssh/sshd_config.new /etc/ssh/sshd_config
