The list of jobs in this pipeline include: * hadolint:
This job analyses Dockerfile using the hadolint tool to
catch potential issues and best practices. *
chatgpt_analysis: This job creates an analysis of the other
jobs in the pipeline, using OpenAI’s ChatGPT AI model. *
docker-hub-build-arm, docker-hub-build: These
jobs build the Docker image on ARM and on AMD64 respectively. *
docker-hub-test-arm, docker-hub-test: These
jobs test the Docker image on ARM and on AMD64 respectively, by checking
that the internet is reachable when using the built Docker image as a
proxy. * dive-arm, dive: These jobs use the
dive tool to explore and analyse the layers in the Docker
image on ARM and AMD64 respectively. * push-docker-hub-arm,
push-docker-hub: These jobs push the Docker image to the
DockerHub registry on ARM and AMD64 respectively, both under the
latest and version-specific tags. *
SquidParseConfig: This job checks the syntax of the Squid
configuration file in a built Docker image.
Here is a summary of the purpose and detailed explanation of each job:
hadolint Dockerfile README.md docker-compose
gitlabci squid The purpose is to ensure the Dockerfile follows good
practices and does not contain any issue that can lead to errors.
Dockerfile README.md docker-compose gitlabci squid The command
hadolint --ignore DL3008 Dockerfile is used to run the
Hadolint Docker linting tool on the Dockerfile. The
--ignore DL3008 flag is used to ignore a specific rule
(DL3008: Pin versions in apt get install).
chatgpt_analysis Dockerfile README.md
docker-compose gitlabci squid The purpose is to provide a detailed
explanation of the jobs in the pipeline. Dockerfile README.md
docker-compose gitlabci squid The script first updates the system
packages, and installs necessary dependencies including curl, git, jq,
pandoc, and openssh-client. Dockerfile README.md docker-compose gitlabci
squid The Squid version is fetched by making a cURL request to the Squid
versions web page and parsing the response to find the current version.
This version is stored in the variable SQUID_VERSION.
Dockerfile README.md docker-compose gitlabci squid The content of the
.gitlab-ci.yml file and its included files is read and
stored in the JOBS_CONTENT variable. Dockerfile README.md
docker-compose gitlabci squid The latest commit is found using
git log -1 and stored in LAST_COMMIT.
Dockerfile README.md docker-compose gitlabci squid Using the variables
CONTENTS, LAST_COMMIT,
JOBS_CONTENT, etc., a string is constructed to be sent to
the ChatGPT API for creating a text explaining the jobs. Dockerfile
README.md docker-compose gitlabci squid The variables are formatted to
JSON and sent to the ChatGPT API. The response received from the API is
parsed and stored, and also printed out. Dockerfile README.md
docker-compose gitlabci squid The SSH key is added using
ssh-add <(echo "$SSH_NOSTROMO_KEY"). Dockerfile
README.md docker-compose gitlabci squid The API response is converted to
an HTML file using
pandoc -s --from=markdown+smart --to=html --metadata=encoding=UTF-8 -o chatgpt_analysis_$(date +%Y%m%d).html chatgpt_analysis_$(date +%Y%m%d).md.
Dockerfile README.md docker-compose gitlabci squid This HTML file is
transferred to a remote server using scp.
docker-hub-build-arm, docker-hub-build Dockerfile README.md docker-compose gitlabci squid These jobs build the Docker image for Squid from the Dockerfile. Dockerfile README.md docker-compose gitlabci squid Docker login is made using provided DockerHub username and token. Dockerfile README.md docker-compose gitlabci squid The script then navigates to the project directory, installs cURL, fetches the Squid version, builds and tags the Docker image, and pushes it to DockerHub.
docker-hub-test-arm,
docker-hub-test Dockerfile README.md docker-compose
gitlabci squid These jobs test the Docker image for Squid by running a
simple cURL command with the Squid server as the proxy. Dockerfile
README.md docker-compose gitlabci squid The current Docker image is used
as a service under the alias squid. Thus, the script
updates the system package listings, installs cURL, and uses cURL to
make a request to ‘https://www.google.fr’ using
https_proxy=http://$CONTAINER_TEST_NAME:3128.
dive-arm, dive Dockerfile
README.md docker-compose gitlabci squid These jobs run the
dive tool on the built Docker image, a tool to explore and
analyze the layers in the Docker image.
push-docker-hub-arm,
push-docker-hub Dockerfile README.md docker-compose
gitlabci squid These jobs push the Docker image to DockerHub under the
latest and version-specific tags. Dockerfile README.md
docker-compose gitlabci squid Docker login is made using the provided
DockerHub username and token. The current Docker image is pulled, the
Squid version is fetched again from Squid, the image is tagged with the
version-related and the latest tags, and pushed to DockerHub.
SquidParseConfig Dockerfile README.md
docker-compose gitlabci squid This job checks the Squid configuration
for syntax errors. It uses the Squid binary to parse the configuration
file and checks the output for the string ERROR to detect
any syntax errors.
In the GitLab CI/CD pipeline, artifacts are the files created by GitLab Runner during the execution of a job. They are stored and linked for browsing or downloading on GitLab server.
In this pipeline the following outcomes or artifacts are expected:
hadolint job’s log would contain the reported issues
found by the hadolint tool in Dockerfile.chatgpt_analysis job saves the explanation text from
ChatGPT as a markdown file and an HTML file. These files are saved as
artifacts and can be downloaded from the GitLab server.docker-hub-build* jobs’ logs would contain information
during the Docker build process.docker-hub-test* jobs’ logs would confirm whether Squid
is working as expected as a proxy.dive, dive-arm would provide analysis
information about Docker image layers.push-docker-hub* jobs’ logs would contain information
about Docker image being pushed to DockerHub under different tags.SquidParseConfig job’s log would show the output of the
Squid configuration check.In this pipeline, various environment variables are used, such as
CI_BUILDS_DIR and CI_PROJECT_NAME provided by
GitLab CI/CD, DOCKER_HUB_USER and
DOCKER_HUB_TOKEN for logging into DockerHub,
SQUID_VERSION for specifying the version of Squid to build,
and CHATGPT_API_KEY for making requests to the ChatGPT
API.
Various files are also referenced in the jobs, such as
.gitlab-ci.yml for the pipeline configuration,
Dockerfile for building the Docker image, and
chatgpt_analysis*.html for the output from the ChatGPT
analysis.
The pipeline has the following dependencies: *
docker-hub-test* jobs are dependent on
docker-hub-build* jobs. * push-docker-hub*
jobs are dependent on docker-hub-test* jobs.
This commit removes a markdown file from the website. It could potentially impact the pipeline if the removed file was previously used or referenced in any of the jobs.
