* 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

h4. Clone a git repository into the Docker container by adding a line to the Dockerfile

* 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

# 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>

h4. Quick requirements.txt introduction

* requirements.txt is a way to easily install many python packages by recursively reading through a text file

* This text file can either be generated...

** Manually, by writing the required python packages into the text file.

*** Note: it is good practice to specify the version of the package. Such as...

	<pre><code class="bash">

matplotlib==3.3.4

</code></pre>

** Automatically, by running the following command

	<pre><code class="bash">

pip freeze > requirements.txt

</code></pre>

*** *Note:* This command will include all packages installed.

* A Docker container can install all these packages upon building its image by adding a few lines to the Dockerfile

* 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

# Use the most up-to-date version of pip3.9

RUN pip install --upgrade pip

# Install git and ssh

RUN apt-get update && apt-get install -y git openssh-client

# Create a working directory

WORKDIR /workspace

# Clone GitHub

RUN git clone https://github.com/trottar/solid_beamtest_hallc_2022.git

# copy the dependencies file to the working directory

COPY requirements.txt .

# install dependencies

RUN pip install -r requirements.txt

# 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>

* *Note:* I also made some other adjustments such as...

** Moved the pip installation of jupyter directly into the requirements.txt

** Added an installation for git and ssh to avoid completely clean image creations. 

** Added a pip install --upgrade pip to assure pip is the latest version for python3.9

h4. Useful Docker Commands

* Remove all stopped containers (use with caution)

	<pre><code class="bash">

docker system prune -a

</code></pre>

h4. Near-term Goals

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