Docker

week 4 of Applaudo Studios Program

Description

Develop a docker container of a web server and publish it into a public registry, providing both CI / CD for the image and the repository.

Note you can run the necessary commands to run the container by using the script.sh file: ./script.sh

Requirements

• Create a docker container of a web server
• Publish the image into a public registry
• Provide CI / CD for the image and the repository

Image creation process

1. Create a file and name it Dockerfile in your local directory
2. Build the image with the following command:

docker build -t website .

3. Run the image with the following command:

docker run -d --name website -p 5000:4000 waltergsteven/website

The name of the container is website and the port is 5000

4. Check the container is running with the following command:

docker ps

5. Open your browser and go to http://localhost:5000 the website will look like this:

6. Push the image to Docker Hub with the following command:

docker push waltergsteven/website

7. Go to Docker Hub and check the image is there:

Run the image in your local machine

1. Pull the image from Docker Hub with the following command:

docker pull waltergsteven/website:latest

You can also find the image in the Docker Hub

2. Run the image with the following command:

docker run -d --name website -p 5000:4000 waltergsteven/website

The name of the container is website and the port is 5000 use http://localhost:5000 to see the website in your browser

CI/CD

The CI/CD is done using GitHub Actions, the workflow is the following:

1. When a pull request from the release branch to the develop branch is created, the branch workflow is triggered.
2. The branch workflow will delete the release branch once the pull request is merged.
3. When a push is made to the develop branch, the pr workflow is triggered.
4. The pr workflow will create a pull request from the develop branch to the release branch.
5. Once the pull request is merged, the docker-image workflow is triggered.
6. The docker-image workflow will build the image and push it to Docker Hub.
