How do you add local files to a Docker image?

The “docker build” command is used to package local files into an image.

Here is an example command:

docker build -t <镜像名称> <Dockerfile路径>

Where is the name of the image to be created, and is the path to the Dockerfile file containing the build instructions.

In a Dockerfile, you can use the COPY command to copy local files into the image. For example:

COPY ./local_file.txt /app/local_file.txt

The command above copies the file local_file.txt in the current directory to the /app directory in the image.

Next, run the ‘docker build’ command with the directory where the Dockerfile is located as the to build the image with local files.
