# **HHA504 || Deploying and Managing Containers with GCP Cloud Run and Azure Container Apps**
---

#### **🎯** This task is part of my assignment focused on deploying and managing containers using [GCP Cloud Run](https://github.com/raqssoriano/HHA504_assignment_containers/edit/main/README.md#-deploy-to-gcp-cloud-run) and [Azure Container Apps](https://github.com/raqssoriano/HHA504_assignment_containers/blob/main/README.md#-deployment-using-azure-container-apps). I am learning [how to containerize an application with Docker](https://github.com/raqssoriano/HHA504_assignment_containers/edit/main/README.md#-containerize-a-simple-application) and deploy it on both platforms.

#### **📌** My [Reflections on the deployment process and Final thoughts](https://github.com/raqssoriano/HHA504_assignment_containers/edit/main/README.md#-reflections-on-the-deployment-process) on both platforms.

---

docker run -p 5010:5000 **`hha504docker:v1`**

4. [Publish to Docker Hub](https://github.com/hantswilliams/HHA-504-2024/blob/main/other/module10/deployment_instructions.md#publish-to-docker-hub)

- (1) **`docker login -u raqssoriano`**
- (2) *command structure*:
- **`docker tag hha504docker:v1 raqssoriano/hha504docker:v1`**
- (3) *command to push structure*:
- **`docker push raqssoriano/hha504docker:v1`**

## ☞ *Create a Container for a Simple Application*
➤ **Creating a Docker Image:**
1. Using the **`Cloud Shell Editor`**, I created a new directory called "**`docker-hw`**" and created a file named "**`app.py`**". Inside this file, I created a simple flask application that I [copied from my professor](https://github.com/hantswilliams/HHA-504-2024/blob/main/other/module10/app.py) and modified to make it more personalized. See the python script/code below.

```python
from flask import Flask, render_template, render_template_string
import random

app = Flask(__name__)

#@app.route('/')
#def index():
# return "

Life is Beautiful!!! Sending a message from Raqs flask app in a Docker Container! :-)!

"

@app.route('/')
def index():
return render_template('index.html')

if __name__ == '__main__':
app.run(debug=True, host='0.0.0.0', port='5000')
```

2. I built the Docker image on my local machine and tested it to make sure it runs correctly. See the screenshots below how I accomplished this section.

.

4. Prior to creating a flask app, I signed up for a new account on **`Docker Hub`** by connecting my **GitHub** account, and created a directory named "**`raqssoriano`**". In this directory, I created a repository called "**`hha540docker`**". This was instrumental in successfully deploying the flask app I had previously created.

.

5. In the **`Cloud Shell Editor`**, I created a new file named "**`dockerfile`**" in the "**`docker-hw`**" directory, which contains instructions on how to create or build a _**Docker image**_. This is taken from [Professor Hants' HHA-504-2024 GitHub repository](https://github.com/hantswilliams/HHA-504-2024/blob/main/other/module10/Dockerfile).

```dockerfile
FROM python:3.11-alpine
WORKDIR /app
COPY . /app
RUN pip install -r requirements.txt
EXPOSE 5000
CMD ["python", "app.py"]
```

---
## ☞ *Deployment on GCP Cloud Run*

1. I deployed my Docker image to DockerHub.

.

2. I navigated to _**GCP**_ and searched for **`Cloud Run`** in the search bar, and clicked **`Deploy Container`** and **`Service`**.

3. I configured the deployment, including setting environment variables and scaling options according to the instructions.

.

.

.

4. I tested the deployed application to make sure it's running correctly.

---
---
## ☞ *Deployment Using Azure Container Apps*

1. I navigated to _**Azure**_ and searched for **`Container Apps`** in the search bar, and **created** a **Container App** named "**`raqs504flask`**." See the screenshots below.

2. Similar to GCP Cloud Run, I ensured that the configuration process was completed by creating a **resource group** called "**`my504dockerhw`**."

.

3. I deployed the containerized application using the Docker image that I initially pushed or deployed to **`Docker Hub`**.

4. Similar to GCP Cloud Run, I [tested the deployed application](https://raqs504flask.thankfulforest-d1c4952d.centralus.azurecontainerapps.io/) to make sure it's running correctly.

## ☞ *Reflections on the Deployment Process*

- 📌 **`GCP Cloud Run`**:
- I did not have any issues during the deployment process. It was pretty easy. I have to give credit to Professor Hants' zoom class video recording and the code/script examples in his GitHub repository.
- Although I wonder if I can do it on my own without guidance from my professor. I would probably have difficulty figuring out which code/script to use in Docker Hub and in attempting to deploy the Docker image to GCP Cloud Run. This might be challenging, but I might consider searching for the correct documentation. If I remember correctly from the recorded video, my professor also looked up the script to be used. This might work for me in the future.

- 📌 **`Azure Container App`**:
- In [step 3, where I attempted to deploy the Docker image from my Docker Hub](https://github.com/raqssoriano/HHA504_assignment_containers/blob/main/Azure%20Container%20App/4.png), this is the part that caused my deployment process to fail **multiple times**. In **Registry Login Server**, I initially clicked the *information icon* (the icon with an "i" that appears after the registry login server field) and followed the example by first typing my Docker Hub username. After watching the [YouTube video by Microsoft DevRadio](https://www.youtube.com/watch?v=y81Kpqaf9u0&t=31s), I left "**`docker.io`**" in the registry login server field as it is, then I successfully deployed the container app I created in Azure.
- I noticed that Azure _**automatically generates**_ a unique identifier for my newly created container app, [as seen in the highlighted application URL](https://github.com/raqssoriano/HHA504_assignment_containers/blob/main/Azure%20Container%20App/11.png), which includes the word "**`thankfulforest`**." As compared to GCP, I have the flexibility to create my own unique identifier, although I'm not quite sure if GCP has the same feature as Azure that automatically generates this.

- 📌 **`Final Thoughts`**:
- If I hadn't had issues with the registry login server field as previously mentioned, I can say that the deployment process was pretty much the same on both platforms, with the creation and deployment steps being easy to follow. With that being said, I like both GCP Cloud Run and Azure Container App. I find this assignment quite enjoyable and interesting because it seems that I can apply my creative side if I gain more experience in figuring out the code/script to use for images or perhaps videos that I want to upload and deploy to a certain portal. When I get more experience, I might apply everything I've learned in this assignment to create a personal or portfolio website to highlight my professional journey and showcase all my work or assignments/projects from grad school. This will provide an interesting way for potential employers to learn about my background and skills or expertise.🤓
