Purpose of Each Job

Job: Quality

This job uses hadolint, a Dockerfile linter, to analyze the Dockerfile and ensure it follows best practices for Dockerfiles.

before_script:
 - cd $CI_PROJECT_DIR 
script:
 - hadolint --ignore DL3008 Dockerfile 

cd $CI_PROJECT_DIR changes the current working directory to the root project directory in CI build.

hadolint --ignore DL3008 Dockerfile runs hadolint on the Dockerfile, ignoring linting rule DL3008.

Job: Get-version

This job fetches the latest version of Squid from GitHub and updates the README file and an environment file (variables.env) with this version.

script:
 - apt update && apt install git curl ca-certificates -y --no-upgrade --no-install-recommends --no-install-suggests
 - export SQUID_VERSION=$(curl -LsXGET https://github.com/squid-cache/squid/releases/latest | grep -m 1 "Release" | cut -d " " -f4 |tr -d 'v')
 - echo "SQUID_VERSION=$SQUID_VERSION" > variables.env
 - echo $SQUID_VERSION
 - sed -i "s/{{SQUID_VERSION}}/$SQUID_VERSION/g" README_template.md
 - sed -i "s/{{DATE}}/$(date +%Y%m%d)/g" README_template.md
 - cp README_template.md README.md
 - git config user.email "fredbcode"
 - git config user.name "fredbcode"
 - git add README.md
 - git commit -m "README Auto update [skip ci]" || true
 - git push https://$GITLAB_TOKEN@gitlab.com/fredbcode-images/squid.git HEAD:master || true

In the script section, it updates the package list (apt update) and installs git, curl, and ca-certificates.

Then it fetches the latest release of Squid from its GitHub repository (curl -LsXGET...) and stores this version in the SQUID_VERSION environment variable for subsequent steps.

Next, it updates the variables.env file and the README_template.md file with the new Squid version. It also adds the current date to README_template.md before copying it to README.md.

Finally, it commits any changes made to README.md and pushes them to the repository using Git.

Job: Docker-hub-build

This job builds the Docker image using the Dockerfile provided in the project and the Squid version previously fetched. The name of the image includes the “build-noprod” tag and appropriate CPU architecture (AMD64 or ARM).

before_script:
 - docker login -u "$DOCKER_HUB_USER" -p "$DOCKER_HUB_TOKEN" $DOCKER_HUB_REGISTRY
script:
 - source variables.env
 - docker build --build-arg SQUID_VERSION=$SQUID_VERSION --pull -t $CONTAINER_BUILD_NOPROD_NAME .
 - docker push $CONTAINER_BUILD_NOPROD_NAME

In the before_script section, it logs into Docker Hub using a username and a password stored in secrets.

In the script section, it sources the variables.env file to use the Squid version inside this file. Then it builds the Docker image using this version with the docker build... command, and then pushes this image to Docker Hub.

Job: Docker-hub-test

This job tests the Docker image built in the previous step. It starts the Squid container and tries to use it as a proxy to make a web request.

before_script:
 - apt update && apt install -y curl --no-upgrade --no-install-recommends --no-install-suggests
script:
 - export https_proxy=http://$CONTAINER_TEST_NAME:3128 && curl -k https://www.google.fr

In the before_script section, it updates the package list (apt update) and installs curl for making web requests.

In the script section, it sets up the Squid proxy for curl (export https_proxy...) and makes a request to an external server (curl -k...).

Job: Docker-hub-pushtag

This job pushes the Docker image built and tested in the previous steps to Docker Hub. It tags the image with the Squid version and pushes these images to the registry.

before_script:
 - docker login -u "$DOCKER_HUB_USER" -p "$DOCKER_HUB_TOKEN" $DOCKER_HUB_REGISTRY
script:
 - source variables.env
 - docker pull $CONTAINER_BUILD_NOPROD_NAME
 - docker tag $CONTAINER_BUILD_NOPROD_NAME $HUB_REGISTRY_IMAGE:$SQUID_VERSION 
 - docker push $HUB_REGISTRY_IMAGE:$SQUID_VERSION

In the before_script section, it logs into Docker Hub using a username and a password stored in secrets.

In the script section, it sources the variables.env file to use the Squid version inside this file. It then pulls the Docker image from Docker Hub and names (tags) it with the Squid version. Finally, it pushes these tagged images to Docker Hub.

Job: Docker-hub-build-arm

Similar to Docker-hub-build, but the image is built for ARM architecture.

Job: Docker-hub-test-arm

Similar to Docker-hub-test, but the test is run on the ARM architecture image.

Job: Docker-hub-pushtag-arm

Similar to Docker-hub-pushtag, but the ARM architecture image is pushed to Docker Hub.

Job: test

This stage includes several jobs from CI templates like security static application testing (SAST). It analyzes the code for possible security vulnerabilities.

Job: Docs

This job uses chatgpt to analyze the jobs and update the README file with explanations of jobs. It also updates the README on Docker Hub.

script:
 ....
 - RESPONSE=$(curl -X POST https://api.openai.com/v1/chat/completions -H "Authorization:Bearer $CHATGPT_API_KEY" -H "Content-Type:application/json" -d "$JSON_CONTENT")
 ....

In the script section, it sends a POST request to the OpenAI API with the key and content as JSON. It gets the API’s response about the analysis of the job.

Dependencies Between Jobs or Stages

The jobs are connected and dependent on each other as follows:

1. Quality: Independent job.
2. Get-version: Independent job. It gets the version for subsequent jobs so runs first.
3. Docker-hub-build: Depends on Get-version for Squid version.
4. Docker-hub-test: Depends on Docker-hub-build as it tests the built image.
5. Docker-hub-pushtag: Depends on Docker-hub-test and Get-version. It pushes the image to the registry after it is built and tested successfully.
6. Docker-hub-build-arm: Depends on get-version for Squid version.
7. Docker-hub-test-arm: Depends on Docker-hub-build-arm as it tests the built image.
8. Docker-hub-pushtag-arm: Depends on Docker-hub-test-arm and get-version. It pushes the image to the registry after it is built and tested successfully.
9. test: Depends on all build and test jobs. It should test the final state of the code after all changes.
10. Docs: Depends on Get-version, Docker-hub-test, and Docker-hub-test-arm because it uses their results.

Expected Outcomes or Artifacts

• Quality: Linting errors from hadolint if any.
• Get-version: The latest Squid version saved in variables.env. README.md is also updated and committed to the repository with the latest version of Squid.
• Docker-hub-build: The Docker image built for the latest Squid version.
• Docker-hub-test: The result of the web request made using the Squid proxy. If the request is successful, the Docker image is deemed to have passed the test.
• Docker-hub-pushtag: The Docker image pushed to Docker Hub, tagged with the latest Squid version.
• Docker-hub-build-arm: Similar to Docker-hub-build but for the ARM architecture.
• Docker-hub-test-arm: Similar to Docker-hub-test but for the ARM architecture.
• Docker-hub-pushtag-arm: Similar to Docker-hub-pushtag but for the ARM architecture.
• test: Results of various tests like SAST.
• Docs: The chatgpt analysis result of the jobs, and the updated README in Docker Hub. The analysis result is also stored as a Markdown file as an artifact.

Latest Commit: 1a120b0 README Auto update [skip ci]

In this commit, the README file was updated (likely with a new Squid version) and the commit was made with the message “README Auto update [skip ci]”. The “[skip ci]” in the commit message tells GitLab CI/CD to skip running pipelines for this commit. The purpose of this is probably to avoid unnecessary pipeline runs for README updates. The impact of this commit is minimal on the pipeline as it only affects the README file and does not trigger a new pipeline run.
