Scenario: A developer, let’s call them Alex, is working on a project using the Docker Genai-Stack and encounters an issue. They notice that the application is not starting as expected, and they see an error message in the terminal.
To help Alex identify and resolve the issue, we will follow these steps:
Check the error message: The first step is to understand the error message. Alex should read the error message carefully and note any relevant details, such as the name of the container, the error code, and any specific error messages. For example, if the error message is related to a missing dependency, Alex should check the
requirements.txt
file in the project directory to ensure all required packages are installed.Check the logs: The next step is to check the container logs to get more information about the issue. Alex can use the
docker logs
command to view the logs for the container. For example, if the container name ismy-app
, Alex can rundocker logs my-app
. The logs may provide more context about the error, such as when it occurred and any related error messages.Check the Dockerfile: If the issue is related to the Dockerfile, Alex should check the file to ensure it is correct. They should verify that the base image is specified correctly, that all dependencies are installed, and that the application is correctly copied into the container. For example, if the issue is related to a missing dependency, Alex should check the
Dockerfile
to ensure it is installed using aRUN
command or added to therequirements.txt
file.Check the documentation: If Alex is unable to identify the issue based on the error message and logs, they should consult the documentation for the Docker Genai-Stack. The documentation may provide solutions to common issues or troubleshooting steps. For example, the Docker Genai-Stack documentation may provide instructions for troubleshooting container startup issues or configuring the environment.
Check the community: If Alex is unable to find a solution in the documentation, they should check the community for help. They can search for similar issues on forums or ask for help on relevant channels. For example, they can search for similar issues on the Docker Genai-Stack GitHub repository or ask for help on the Docker community forum.
Tests to verify the answer:
Check that the application starts after making the necessary changes: Once Alex has identified and resolved the issue, they should verify that the application starts correctly. They can do this by running the
docker start
command for the container and checking the logs for any error messages.Check that the application is functioning correctly: After the application has started, Alex should verify that it is functioning correctly. They can do this by accessing the application in a web browser or using other testing tools.
