* Darren ran with Python3.9

* Docker (containerization) Definition

** Containerization is a technology that allows developers to package and run applications along with all their dependencies in isolated environments called containers. This ensures that the application runs consistently across different computing environments, from a developer's laptop to testing, staging, and production.

** Docker is a popular platform that simplifies containerization. It provides tools to create, deploy, and manage containers. With Docker, developers can write code locally, share their work with colleagues, and deploy to production in a seamless and efficient manner. Docker containers are lightweight, fast, and portable, making them ideal for modern software development and deployment.

h4. Setting Up Jupyter Notebooks in Docker

# Create a directory to store, build, and run Docker container

	<pre><code class="bash">

cd /path/to/directory

mkdir beamtest_dir

cd beamtest_dir

</code></pre>

# Once in the new directory, create a Dockerfile

	<pre><code class="bash">

touch Dockerfile

</code></pre>

# Using the text editor (e.g., vim, gedit, or emacs) of your choice, edit the Dockerfile with the following information

	<pre><code class="bash">

# Use the official Python 3.9 image as the base image

FROM python:3.9

# Install Jupyter Notebook and other dependencies

RUN pip install --no-cache-dir jupyter

# Create a working directory

WORKDIR /workspace

# Expose the Jupyter Notebook port

EXPOSE 8888

# Set the default command to start Jupyter Notebook

CMD ["jupyter", "notebook", "--ip=0.0.0.0", "--port=8888", "--no-browser", "--allow-root"]

</code></pre>

# Build the Docker image (e.g., helloworld)

	<pre><code class="bash">

docker build -t helloworld .

</code></pre>

# Run the Docker container

</code></pre>

	<pre><code class="bash">

docker run -p 8888:8888 helloworld

</code></pre>

# Jupyter Notebook is now running. Navigate to a browser and type in either

* The custom token authorization screen</code></pre>

	<pre><code class="bash">

http://localhost:8888

</code></pre>

* To bypass the token screen, copy/paste the URL that splashes in the terminal into your browser

h4. Near-term Goals

# Try and get the "python tutorial":https://github.com/trottar/UVA_summer_students Jupyter notebooks working in a container.

h4. Setting Up Bash Script for Running Docker

# Create a bash script

	<pre><code class="bash">

touch run_docker.sh

</code></pre>

# Using the text editor (e.g., vim, gedit, or emacs) of your choice, edit run_docker.sh

	<pre><code class="bash">

#!/bin/bash

# Build docker image ($1 is the first bash script argument)

docker build -t $1 .

# Run the docker container (renaming it with the '_container' string)

docker run -p 8888:8888 --name "${1}_container" $1

</code></pre>

# Adjust permissions with "chmod":https://www.theserverside.com/blog/Coffee-Talk-Java-News-Stories-and-Opinions/how-permissions-chmod-with-numbers-command-explained-777-rwx-unix to allow script execution

	<pre><code class="bash">

chmod 755 run_docker.sh

</code></pre>

# Execute run_docker.sh with container name (e.g., helloworld)

	<pre><code class="bash">

./run_docker.sh helloworld

</code></pre>

The docker image should be properly built and the container should be running. Follow instructions from "yesterday":https://redmine.jlab.org/projects/uva-phys-zheng/wiki/ML_beam_test_PID_Meetings#May-29th-2024 to continue.

h4. Setting Up Bash Script for committing Docker container

This should be done while a docker container is running and performed in another terminal.

# Create a bash script

	<pre><code class="bash">

touch commit_docker.sh

</code></pre>

# Using the text editor (e.g., vim, gedit, or emacs) of your choice, edit commit_docker.sh

	<pre><code class="bash">

#!/bin/bash

# Create a formatted string with date to organize committed containers

# - `date` is a command that prints or sets the system date and time.

# - `+%H` extracts the hour in 24-hour format.

# - `+%M` extracts the minute.

# - `+%S` extracts the second.

# - `+%Y` extracts the year.

# - `+%m` extracts the month.

# - `%d` extracts the day.

f_date=$(date +%Y-%m-%d_h%Hm%Ms%S)

# While a docker container is running (with root name given as first argument), 

# commit to a dated container so that changes in the container are saved

docker commit "${1}_container" "${1}_${f_date}"

</code></pre>

# Adjust permissions with "chmod":https://www.theserverside.com/blog/Coffee-Talk-Java-News-Stories-and-Opinions/how-permissions-chmod-with-numbers-command-explained-777-rwx-unix to allow script execution

	<pre><code class="bash">

chmod 755 commit_docker.sh

</code></pre>

# Execute run_docker.sh with container name (e.g., helloworld)

	<pre><code class="bash">

./commit_docker.sh helloworld

</code></pre>

h4. Useful Docker Commands

* To see all docker images

	<pre><code class="bash">

docker images

</code></pre>

* To see all docker containers running

	<pre><code class="bash">

docker ps

</code></pre>

* To end specific docker container

	<pre><code class="bash">

docker stop <container_id>

</code></pre>

* To end all docker container

	<pre><code class="bash">

docker stop $(docker ps -q)

</code></pre>

h4. Near-term Goals

# Try and get the "python tutorial":https://github.com/trottar/UVA_summer_students Jupyter notebooks working in a container.

# Take a look at the "GitHub ML Beam Test Repository":https://github.com/JeffersonLab/solid_beamtest_hallc_2022/tree/main/aiml

* In particular, look at the script "solid_beamtest_hallc_2022/aiml/Pencil_Beam/Pencil_Cher_ML.ipynb":https://github.com/JeffersonLab/solid_beamtest_hallc_2022/blob/main/aiml/Pencil_Beam/Pencil_Cher_ML.ipynb

** Try to get this notebook working in a container by creating a requirements.txt file (use this "site as a general guide":https://www.docker.com/blog/containerized-python-development-part-1/)

** We will cover this in detail tomorrow

# Using the text editor (e.g., vim, gedit, or emacs) of your choice, edit the Dockerfile with the following information (the python tutorial GitHub repo is used as an example)

	<pre><code class="bash">

# Use the official Python 3.9 image as the base image

FROM python:3.9

# Install Jupyter Notebook and other dependencies

RUN pip install --no-cache-dir jupyter

# Create a working directory

WORKDIR /workspace

# Clone GitHub repo

RUN git clone https://github.com/trottar/UVA_summer_students.git
