CIPRTrainer GUI application using Docker Sample Clauses

CIPRTrainer GUI application using Docker. The second approach to install the CIPRTrainer is using Docker. It enables the user “to pack- age an application with all of its dependencies into a standardized unit for software develop- ment”6. Filesystem, system libraries, and tools are provided by the Docker container. The specific dependencies (libs/bins) for the application can be pulled from DockerHub, a public repository. These dependencies have to be defined into the Dockerfile. The file (plain text file) contains all necessary configurations and dependencies for installing and running the CIPRTrainer: # Dockerfile.txt FROM node:4 # loads node dependencies from DockerHub (node dependen- cies) RUN useradd -ms /bin/bash node # create user, create home directory, use bash ADD . /home/node/ciprtrainer # copy src to new directory RUN chown -R node:node /home/node # asign user to src # load npm, xxxxx and gulp RUN npm install -g npm RUN npm install -g xxxxx gulp RUN apt-get update USER node # set the user node when running the image EXPOSE 3005 # inform Docker container to listen on a specified network port at runtime WORKDIR /home/node/ciprtrainer # change work directory # install ciprtrainer RUN npm install RUN gulp build CMD node app.js # run ciprtrainer 6 xxxxx://xxx.xxxxxx.xxx/what-docker To run Docker, Docker7 needs to be installed. Docker provides a specific terminal for Win- dows machines. The user has to launch the Docker terminal. It starts with a configuration pro- cess, which assigns an NAT-IP address to the Docker Engine. Then, the user has to enter the following instructions: # navigate to git project ciprnet $ cd src/ciprtrainer # contains Dockerfile $ docker build -t ciprtrainer . $ docker run -p 80:3005 –t ciprtrainer The first instruction navigates to the source files of the CIPRTrainer. The second instruction builds a Docker image, which contains execution parameters within a container runtime. The last command creates the Docker container, which is a runtime instance of the Docker image. The tag -p maps the exposed port of the container to the port on the Docker Engine. The CIPRTrainer is now accessible on the NAT-IP address of the Docker Engine on port 80.
