How can you retrieve logs from a Docker container?

• A. By using the command `docker fetch logs`
• B. By using the command `docker see logs [container_id]`
• C. By using the command `docker logs [container_id]`
• D. By using the command `docker show logs [container_id]`

Answer: (C)

The correct method to retrieve logs from a Docker container is by using the command `docker logs [container_id]`. This command allows users to access the standard output and standard error streams from the specified container, providing insights into the running processes within that container. When you execute this command, Docker interacts with the container's logging driver, which is responsible for capturing logs generated by applications running inside the container. This way, developers and system administrators can diagnose issues, monitor application behavior, and ensure that services are functioning as intended. In contrast, the other options provided do not correspond to valid Docker commands for fetching logs. They do not exist in Docker’s command-line interface, which can lead to confusion for users who may be familiar with other command syntax but need to be directed correctly for Docker-specific tasks. This reinforces the importance of understanding the correct commands to use in Docker for effective container management.
