Build the New Image
A new custom Docker image can be built on any host where Docker binaries are installed.
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 must add the
--network=hostoption to the build command:
docker build --network=host -t <image-name>:<tag> . -f Dockerfile
