  10. update_dockerhub_readme: This job in the Docs stage updates the Docker Hub description with the latest README.md content.

Purpose of each job

Each job has its specific purpose and objective. Here are the detailed explanations:

  1. hadolint: This job is used to enforce Dockerfile best practices. It uses a Linting tool called Hadolint to analyze the Dockerfile and throw warnings/errors if there are any violations. The main command executed in this job is hadolint --ignore DL3008 Dockerfile, it runs the hadolint tool while ignoring the specific rule DL3008. This task helps maintain a standard of quality for Dockerfiles in the project.
cd $CI_PROJECT_DIR 
hadolint --ignore DL3008 Dockerfile
  1. chatgpt_analysis: This job uses the chat-gpt AI model to process detailed explanations of each job in the pipeline. This information is gathered from the .gitlab-ci.yml files and the latest commit. The resulting analysis is then converted to Markdown and HTML, and the HTML version is sent to a remote destination via scp.

  1. docker-hub-build-arm: This job fetches the Squid version, builds the Docker image using Dockerfile, and pushes it to Docker Hub for the ARM architecture. Here, the build process utilizes the cache from the last built image (via --build-arg and --pull options) to speed up the build process.
docker login -u "$DOCKER_HUB_USER" -p "$DOCKER_HUB_TOKEN" $DOCKER_HUB_REGISTRY
source variables.env
docker build -f Dockerfile --build-arg SQUID_VERSION=$SQUID_VERSION --pull -t $CONTAINER_BUILD_NOPROD_NAME_ARM .
docker push $CONTAINER_BUILD_NOPROD_NAME_ARM
  1. docker-hub-test-arm: This job performs a connectivity test of the internet through the built Docker image for the ARM architecture. It sets up a proxy and uses curl to fetch a webpage.
apt update && apt install -y curl
export https_proxy=http://$CONTAINER_TEST_NAME:3128 && curl -k https://www.google.fr
  1. push-docker-hub-arm: This job is responsible for pulling, tagging, and pushing the Docker image to Docker Hub.
docker login -u "$DOCKER_HUB_USER" -p "$DOCKER_HUB_TOKEN" $DOCKER_HUB_REGISTRY
source variables.env
docker pull $CONTAINER_BUILD_NOPROD_NAME_ARM
docker tag $CONTAINER_BUILD_NOPROD_NAME_ARM $HUB_REGISTRY_IMAGE:$SQUID_VERSION-arm 
docker push $HUB_REGISTRY_IMAGE:$SQUID_VERSION-arm
docker tag $CONTAINER_BUILD_NOPROD_NAME_ARM $HUB_REGISTRY_IMAGE:latest-arm 
docker push $HUB_REGISTRY_IMAGE:latest-arm
  1. docker-hub-build: Similar to docker-hub-build-arm, but this job builds the Docker image for AMD64 architectures.
docker login -u "$DOCKER_HUB_USER" -p "$DOCKER_HUB_TOKEN" $DOCKER_HUB_REGISTRY
source variables.env
docker build --build-arg SQUID_VERSION=$SQUID_VERSION --pull -t $CONTAINER_BUILD_NOPROD_NAME_AMD64 .
docker push $CONTAINER_BUILD_NOPROD_NAME_AMD64
  1. docker-hub-test: Similar to docker-hub-test-arm, but this job performs internet connectivity tests through the built Docker image for AMD64 architectures.
apt update && apt install -y curl
export https_proxy=http://$CONTAINER_TEST_NAME:3128 && curl -k https://www.google.fr
  1. push-docker-hub: Similar to push-docker-hub-arm, but this job tags and pushes Docker image to Docker Hub for AMD64 architectures.
docker login -u "$DOCKER_HUB_USER" -p "$DOCKER_HUB_TOKEN" $DOCKER_HUB_REGISTRY
source variables.env
docker pull $CONTAINER_BUILD_NOPROD_NAME_AMD64

  1. getsquid_vars: This job fetches the latest version of Squid from GitHub, saves it into a .env file, and updates the README.md file with the latest version information. If there is a version change, updates the known last version and pushes it to the according GitLab repository.
apt update && apt install git curl ca-certificates
export SQUID_VERSION=$(curl -LsXGET https://github.com/squid-cache/squid/releases/latest | grep -m 1 "Release" | cut -d " " -f4 |tr -d 'v')

echo $SQUID_VERSION
sed -i "s/{{SQUID_VERSION}}/$SQUID_VERSION/g" README_template.md
sed -i "s/{{DATE}}/$(date +%Y%m%d)/g" README_template.md
cp README_template.md README.md
mkdir -p ci || true
if [ -f ci/last_squid_version.txt ]; then LAST_KNOWN=$(cat ci/last_squid_version.txt); else LAST_KNOWN=""; fi

git commit -m "README Auto update and update last_squid_version [skip ci]" || true
git push https://$GITLAB_TOKEN@gitlab.com/fredbcode-images/squid.git HEAD:master || true
  1. update_dockerhub_readme: This job fetches the README.md content from the repository and uses it to update the Docker Hub repository description.
README_CONTENT=$(cat README.md)
PAYLOAD=$(jq -n --arg desc "$README_CONTENT" '{"full_description":$desc}')
TOKEN=$(curl -v -s -X POST -H "Content-Type:application/json" -d '{"username":"'"$DOCKER_HUB_USER"'","password":"'"$DOCKER_HUB_PASSWORD"'"}' https://hub.docker.com/v2/users/login/ | jq -r .token)
curl -X PATCH -H "Authorization:JWT $TOKEN" -H "Content-Type:application/json" -d "$PAYLOAD" https://hub.docker.com/v2/repositories/$HUB_REGISTRY_IMAGE

Parameters, environment variables, and file references

This CI/CD pipeline uses a number of parameters or environment variables and file references:

  1. variables: Variables in the CI/CD pipeline configuration (.gitlab-ci.yml) file are predefined environment variables that GitLab will use when executing jobs. Examples in this pipeline include GIT_CLONE_PATH, CONTAINER_CLIENT_IMAGE, CONTAINER_BUILD_NOPROD_NAME_ARM, CONTAINER_TEST_NAME, DOCKER_HUB_USER, DOCKER_HUB_TOKEN, DOCKER_HUB_REGISTRY, HUB_REGISTRY_IMAGE, SSH_NOSTROMO_KEY.

  2. Artifacts: Artifacts are file references that are produced by a job. These files are stored by GitLab on a successful job execution for later retrieval. For example, the “getsquid_vars” job creates an artifact variables.env containing environment variables.

  3. Files: The .gitlab-ci.yml file, being a file reference, specifies the configuration for the GitLab CI/CD pipeline. Other important files include Dockerfile (used for building Docker image), and ‘README.md’ (provides information about the project).

  4. Local scripts: Some jobs include shell commands directly in the script section. For example, “getsquid_vars” job.

  5. External scripts: Some jobs include shell commands indirectly by calling external scripts. For example, hadolint/hadolint:latest-debian tool is used to lint Dockerfile in “hadolint” job.

Dependencies between jobs or stages

In GitLab CI/CD, jobs typically can be dependent on each other with the help of “needs” and “before_script”. And often, if a previous job fails, the subsequent dependent jobs will not be triggered. - For example, the docker-hub-build-arm and docker-hub-build jobs need getsquid_vars job. It depends on getting the latest Squid version. - The docker-hub-test job needs the docker-hub-build job. Tests are run on the image built by docker-hub-build job. - The push-docker-hub job needs both docker-hub-test and getsquid_vars jobs. It requires the Docker image to be built and tested before it pushes the image to Docker Hub.

Expected outcomes or artifacts

For each job, various outcomes can be expected:

Latest Commit Explanation

The latest commit id: 1b3fce2 “README Auto update and update last_squid_version [skip ci]” is the last change to the repository. In this commit, the README was updated, and the last Squid version on GitLab was updated. This commit does not have any direct implications on the pipeline execution because of the [skip ci], which means CI/CD is going to skip pipeline creation for this commit.
