Dockerfiles for Hawk Container Edition

Hawk Container Edition provides Dockerfiles for installation of Hawk Container Edition components inside the Docker containers.

Dockerfile is a script, which consists of various commands to automatically perform actions on a base image to create a new one. Dockerfiles simplify the process of deployment. The default base image on the provided Dockerfiles is Debian Linux with OpenJDK 11.

Dockerfile Key Commands

The Dockerfiles begin with FROM command which specifies the image that starts the build process. The default base image on the provided Dockerfile is Debian Linux with OpenJDK 11. For example, 
FROM openjdk:11.0.1-jre-slim-stretch

After specifying the base image, define various other methods, commands and arguments (or conditions), in return, provide a new image which is to be used for creating Docker containers. The Dockerfile is then supplied to the Docker daemon to build an image.

Syntax of the Dockerfile command is: 
Command argument argument ...
For example, 
# Print "Hello docker!" 
RUN echo "Hello docker!"

For more details on each command of Dockerfile, refer to the Docker documentation at https://docs.docker.com/engine/reference/builder/.
