"Execute Commands in Docker Containers: Using the CMD Instruction in Dockerfile"

To execute a command in a Docker container using a Dockerfile, you can use the `CMD` instruction. Here's an example: ``` FROM ubuntu:latest RUN apt-get update && apt-get install -y <package-name> CMD ["<command>", "<arguments>"] ``` In the above example, replace `<package-name>` with the name of the package you want to install, and `<command>` with the actual command you want to execute inside the container. You can also provide `<arguments>` if required. Save the Dockerfile and then build an image using the `docker build` command. When you run a container from this image, it will execute the specified command as its main process. ######[AI写代码神器 | 643点数解答 | 2023-12-26 14:08:42]
