Build the New Docker Image
This topic shows you how to use Docker to build a custom image.
A new custom Docker image can be built on any host where Docker binaries are installed, source images are available, and OS repositories and other package repositories are available. To install these binaries, run the following command on the host where you want to build the new image:
docker build -t <image-name>:<tag> . -f Dockerfile
If your Dockerfile makes any outside connection (for example,
curl), you ust add the
--network=hostoption to the build command:
docker build --network=host -t <image-name>:<tag> . -f Dockerfile
