Build multiple images from multiple dockerfile

Is there any way to build the multiple images by managing two different dockerfiles? In my case I want to keep two dockerfile suppose Dockerfile_app1 Dockerfile_app2 within the build context.

docker build -t <image_name> .

The above will pick the dockerfile named as Dockerfile

docker build -t <image_name> Dockerfile_app1

This is also not working for my case as It's expecting the file name as Dockerfile.

I have tried by docker-compose build also. However it din't work.

app1:
  build: Dockerfile_app1
  ports:
   - "80:80"
app2:
  build: Dockerfile_app2
  ports:
   - "80:80"

Just use the -f argument to docker build to specify the name of the Dockerfile to use:

$ docker build -t <image_name> -f Dockerfile_app1 .
...

Or in Compose you can use the dockerfile key from version 1.3 onwards:

app1:
  build: .
  dockerfile: Dockerfile_app1
  ports:
   - "80:80"
app2:
  build: .
  dockerfile: Dockerfile_app2
  ports:
   - "80:80"

Note that the build key is for the build context, not the name of the Dockerfile (so it looked for a directory called Dockerfile_app1 in your case).
