How to build and test normal docker without a compose file. I’m getting too used to compose and should be more flexible with base docker.
Build
docker buildx build . I started trying the simple simple docker build (with buildx for good measure, the one that compose uses)
docker buildx build -t <image_name>:<image_tag> . Now with a name so it’s not a horrible hash
docker buildx build --target <stage_name> -t <image_name>:<image_tag> . with target I can stop build in a certain stage of the dockerfile
Run
docker run -it <image_name>:<image_tag> <some_command> I can not use the command and it will run the default CMD line written in the Dockerfile
--rm removes the container once it stops
-p <local_port>:<container_port> exposes a port from the container
-v <local_folder/named_volume>:<container_folder> creates a bind mount or a volume
