If I have this Dockerfile.fedora ``` FROM fedora ``` This command will instead build an alpine image: ``` STEP 1: FROM alpine Completed short name "alpine" with unqualified-search registries (origin: /etc/containers/registries.conf) Getting image source signatures Docker builds images automatically by reading the instructions from a Dockerfile -- a text file that contains all commands, in order, needed to build a given image. Docker ARG command Example FROM openjdk:13-jdk-alpine ARG JAR_FILE=target/*.jar COPY $ {JAR_FILE} app.jar ENTRYPOINT ["java","-jar","/app.jar"] Variables set using ARG command will be available only till image is built. For me it was argument's order: docker build . -f somepath/to/Dockerfile --build-arg FOO=BAR did not work, but: docker build --build-arg FOO=BAR . Another thing to be careful about is that after every FROM statements all the ARG s get collected and are no longer available. Be careful with m Build the container. You set the values of available arguments via the --build-arg flag for docker build. Usage: RUN
