Building a CI/CD Pipeline using Jenkins
This course covers CI (Continuous Integration) and CD (Continuous Deployment) pipelines, which are one of the four core elements (MSA, CI/CD, DevOps, Container) that make up cloud native applications. Through this course, you can understand and practice the processes needed to build and deploy your own automated pipeline in both local and cloud environments using Jenkins, a CI/CD tool.

Add Ubuntu DinD image for MacOS Apple chip
Hello, this is Lee Do-won.
In the lectures "Building a CI/CD Pipeline Using Jenkins" and "Docker Virtualization Technology for DevOps (Private Harbor Registry)", examples are run by building a practice environment using the DinD (Docker in Docker) method to ensure smooth execution of Docker containers.
However, the Windows and MacOS environments are different, and in the case of MacOS, the Docker image that needs to be configured is different depending on the Intel chip and Apple chip. The image is configured to have the SSH server and Docker engine installed, so that it is easy to use when multiple Docker containers are needed during practice, but it is true that it is difficult to produce it to fit all the students' environments. However, we are trying to update the Docker image so that practice can be done without difficulty in the most general environment.
Recently, when practicing using the docker-server:m1 image used on MacOS Apple chips, errors such as the following were found that prevented practice.
exec /docker-entrypoint.sh: invalid argumentI checked and fixed it through various routes, but it seems that the error occurred in the DinD method that installs the Docker engine in the Docker container and uses it on the arm64 architecture used in MacOS Apple chips. (It is difficult to find the cause because there is no error message or log.)
Example error: https://www.inflearn.com/community/questions/1401289/service-create-%EC%8B%9C%EC%97%90-%EC%97%90%EB%9F%AC-%EB%B0%9C%EC%83%9D
As it was determined that it was difficult to resolve with the image in question, we rebuilt and distributed a version that installed the SSH + Docker engine on the Ubuntu base as shown below.
https://hub.docker.com/repository/docker/edowon0623/docker-server/general
We have confirmed that all the problems that occurred above have been resolved. In Ubuntu, to start the Docker service, first run the command below and then practice.
service start dockerWe will continue to provide an updated practice environment as issues related to practice, such as DinD problems, are identified.
Next week is a holiday. 2024 was a year of many hardships for me personally, but I will start the new year with a new mindset. I will visit you often with better lectures this year. Happy New Year .
thank you
