About the Project
The aim of my project was to tackle the challenges and intricacies that users frequently encounter when configuring Jenkins with Docker. The current process comprises numerous daunting steps associated with security risks. My objective was to resolve this issue using Docker Compose by crafting a Docker Compose file and conducting regular testing. Furthermore, the project included the creation of user-friendly documentation, tutorials, and a streamlined Gitpod setup accessible with just one click.
What will change in Jenkins after this project:
Previously, users had to follow six intimidating steps to install Jenkins with Docker, which appear as follows:
![Creating docker in docker container]()
![Building dockerfile]()
![Creating container from previous image]()
After this project, users will only need two commands:
git clone URLanddocker-compose up -d.This also applies to tutorials that utilize the same Docker setup as mentioned above. After cloning the repository, users will only need to execute
docker-compose up -d <keyword>.Additionally, users can take advantage of a one-click setup using Gitpod to easily experience Jenkins.
Currently, these Docker Compose files undergo regular testing via GitHub Actions. We plan to transition this process to Jenkins in the near future.
Phase 1
During Phase 1, we aimed to accomplish this objective using scripts.
We developed jenkins_init.sh and jenkins_teardown.sh scripts to initiate and stop the containers.
Additionally, we crafted scripts for SSH key generation and the cloning/forking of repositories.
Throughout Phase 1, I gained insights into:
Optimal Git and GitHub practices
Effective conflict resolution in merging
The structure of the Jenkins file system
Creation and utilization of Docker Compose files
Crafting of shell scripts
Building Dockerfiles
Understanding of SSH key mechanisms
Navigating the functionality of Gitpod
Composing technical documentation

Phase 2
In Phase 2, our focus shifted towards integrating Windows as well, given that the shell scripts from Phase 1 were incompatible without Windows Subsystem for Linux (WSL). During this phase, we uncovered the utility of Docker Compose profiles, which turned out to be an excellent solution. These profiles allowed the tutorials to function similarly to our previous scripts, employing designated keywords.
A crucial aspect of the project was automated testing, which introduced me to GitHub Actions, a tool I hadn’t previously experienced. GitHub Actions were employed to test the functionality of Docker Compose files, facilitate the uploading of Docker images to Docker Hub, perform plugin updates, and manage other various tasks.
During Phase 2, my learning encompassed:
Docker Compose files
GitHub Actions
The Jenkins Remote Access API
Next Steps
The upcoming steps for the project involve:
Full integration into jenkins.io.
Transitioning from GitHub Actions to jenkins.ci.
Incorporating the repository into Hacktoberfest with "good first issues" to engage beginner contributors.
As a stretch goal, expanding the project with additional tutorials.

Conclusion
In conclusion, participating in GSoC 2023 was an incredible experience that allowed me to learn new skills and contribute to an open-source project. I am grateful for the opportunity and would like to thank my mentors and the Jenkins community for their support and guidance. I look forward to continuing to contribute.
