You can set image name when building a custom image  like this   docker build -t dude man v2     Will be named dude man v2   Is there a way to define the name of the image in Dockerfile  so I don t have to mention it in the docker build command

Tagging of the image isn t supported inside the Dockerfile  This needs to be done in your build command  As a workaround  you can do the build with a docker-compose yml that identifies the target image name and then run a docker-compose build  A sample docker-compose yml would look like  version   2   services    man      build        image  dude man v2   That said  there s a push against doing the build with compose since that doesn t work with swarm mode deploys  So you re back to running the command as you ve given in your question   docker build -t dude man v2     Personally  I tend to build with a small shell script in my folder  build sh  which passes any args and includes the name of the image there to save typing  And for production  the build is handled by a ci cd server that has the image name inside the pipeline script

Here is another version if you have to reference a specific docker file   version   3  services    nginx      container name  nginx     build        context              dockerfile    docker nginx Dockerfile     image  my nginx latest   Then you just run   docker-compose build
