4. Docker-hub-test stage

• docker-hub-test: This job tests the Docker image built in the previous stage on an x86_64 architecture.
• docker-hub-test-arm: This job tests the Docker image built in the previous stage on an ARM architecture.
• SquidParseConfig: This job checks the syntax of the Squid configuration file.
• dive: This job performs an in-depth analysis of the Docker image layers.
• dive-arm: Similar to above, but for the ARM architecture.

5. Docker-hub-pushtag stage

• push-docker-hub: This job tags and pushes the Docker image to Docker Hub for the x86_64 architecture.
• push-docker-hub-arm: Similar to above, but for the ARM architecture.

6. Docs stage

• chatgpt_analysis: This job uses the OpenAI ChatGPT to generate an analysis report.
• update_dockerhub_readme: This job updates the README on Docker Hub with the latest version information.

Job Explanations:

1) hadolint

Purpose: Dockerfiles require a specific format and set of instructions, and it’s easy to make mistakes. hadolint is a tool that applies a Dockerfile linting ruleset to a Dockerfile, ensuring it meets best practices.

Commands: - hadolint --ignore DL3008 Dockerfile: This command runs the Hadolint linter on the Dockerfile, but with rule DL3008 (Ensure apt-get install is not followed by additional apt-get install) is ignored.

2) getsquid_vars

Purpose: This job obtains the version information for Squid from git. It saves the version information as environment variables, which is then used in the subsequent stages.

Commands:

• curl -LsXGET https://github.com/squid-cache/squid/releases/latest: This command gets the most recent release from GitHub.
• export SQUID_VERSION=$(curl-... | cut | tr): This sets the SQUID_VERSION environment variable from the above command.
• echo "SQUID_VERSION=$SQUID_VERSION" > variables.env: This command writes the variable along with its value to the variables.env file.

3) docker-hub-build

Purpose: To build a Docker image for Squid, where the version is retrieved from previous getsquid_vars job.

Commands:

• docker build --build-arg SQUID_VERSION=$SQUID_VERSION --pull -t $CONTAINER_BUILD_NOPROD_NAME_AMD64 .: This builds the Docker image. The Dockerfile defined build argument SQUID_VERSION is set to the actual version retrieved earlier.

4) docker-hub-test

Purpose: To run tests on the Docker image built in the previous stage. It does this by setting the required environment variables and running a basic curl command via Squid.

Commands:

• export https_proxy=http://$CONTAINER_TEST_NAME:3128 && curl -k https://www.google.fr: This command ensures the Squid proxy is functional by setting the https_proxy environment variable and then using curl to send a request.

5) push-docker-hub

Purpose: Tags and pushes the Docker image to the Docker Hub repository. This includes both the specific Squid version and the latest tag.

Commands:

• docker login -u "$DOCKER_HUB_USER" -p "$DOCKER_HUB_TOKEN" $DOCKER_HUB_REGISTRY: This authenticates the Docker Hub repository.
• docker pull $CONTAINER_BUILD_NOPROD_NAME_AMD64: This pulls the built Docker image.
• docker tag $CONTAINER_BUILD_NOPROD_NAME_AMD64 $HUB_REGISTRY_IMAGE:$SQUID_VERSION-amd64: This tags the Docker image with the Squid version and architecture.
• docker push $HUB_REGISTRY_IMAGE:$SQUID_VERSION-amd64: This pushes the tagged Docker image to Docker Hub.

6) chatgpt_analysis

Purpose: It performs analysis using ChatGPT. Analysis includes version changes, dependencies, expected outcomes, and more. Resulting analysis reports are placed in the project’s artifacts.

Commands:

• The script: section contains a series of commands executing a request to the OpenAI API for in-depth ChatGPT analysis. The output is written to text and HTML files.

7) update_dockerhub_readme

Purpose: It updates the README on Docker Hub with the latest version information. The job fetches the latest README file from the git repository and updates it on Docker Hub.

Commands:

• README_CONTENT=$(cat README.md): Fetches the current README content.
• PAYLOAD=$(jq -n --arg desc "$README_CONTENT" '{"full_description":$desc}'): Formats the README content as a JSON payload to the Docker Hub API.
• TOKEN=$(curl -v -s -X POST -H...): Authenticates with the Docker Hub API to get a token.
• curl -X PATCH -H "Authorization:JWT $TOKEN"..: Updates the Docker Hub repository description with the latest README content.

Every commit affects the whole pipeline, but with the commit: 06179e2 Merge branch 'feature/ci-skip-chatgpt-if-no-version-change' into 'master' [iafred-bot] ci: only run ChatGPT analysis when SQUID_VERSION changed, only jobs that required version check getsquid_vars will run when a SQUID version changes. This efficient approach saves pipeline execution time, and resources when the SQUID_VERSION remains unchanged.
