The
.dockerignorefile tells Docker which files and directories to exclude from the build context. This helps speed up the build process, reduces image size, and avoids copying unnecessary files (e.g.,.git,node_modules, temporary logs) into the image. It functions similarly to.gitignore, optimizing Docker builds by excluding irrelevant or sensitive content.
