Workbench Docker Containers

Alp-Glib

The dockerfile in the alp-glib contains the code to create a docker image that uses and installs linux/x86_64 alpine OS, and glib.

Java-mvn-git

The dockerfile in the java-mvn-git folder contains the code to create a docker image that uses and installs java version 8.131, mvn version 3.8.5, git, and clones Workbench.

Tools

Creating Docker Images

Open the terminal to location of a dockerfile

~/Desktop/WorkBench/Dockerfiles/java-mvn-git> docker build -t (docker username)/java-mvn-git .

That will build an image locally called (docker username)/java-mvn-git

Running a Docker Image

05/05/2022 At time of writing I am currently hosting a docker image on my personal github. We will be using this image as an example on running a docker image.

  • Using the terminal we will run this command:
docker pull ghcr.io/viaduct12/workbench-container:latest
  • Running the command your terminal will output:
~ > docker pull ghcr.io/viaduct12/workbench-container:latest
latest: Pulling from viaduct12/workbench-container
Digest: sha256:71390cc3bd65d065b5575536de309be68b7d9e1e36edfed5b1c64582c77da5e3
Status: Downloaded newer image for ghcr.io/viaduct12/workbench-container:latest
ghcr.io/viaduct12/workbench-container:latest
  • The id of the image is necessary. The command to get the id is docker image ls
~ > docker image ls
REPOSITORY                              TAG       IMAGE ID       CREATED       SIZE
ghcr.io/viaduct12/workbench-container   latest    d0919924e5ae   4 hours ago   424MB
  • To run the image the command is docker run -i -t d0919924e5ae. If your OS is not linux/amd64 you will receive a WARNING and the terminal will change to / #
4:17:51: law in ~ > docker run -i -t d0919924e5ae
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
/ #

After running docker run you'll be able to use terminal commands and because Workbench has already been cloned. You can follow the necessary steps from workbench_getting_started to compile the application

Extracting the JAR file and Resources

  • After building the JAR file, the container id is necessary and the command to get the id is docker container ls
~/Desktop> docker container ls
CONTAINER ID   IMAGE          COMMAND     CREATED          STATUS          PORTS     NAMES
c547ea86f492   d0919924e5ae   "/bin/sh"   24 minutes ago   Up 24 minutes             exciting_golick
  • With the container id, the next command to extract the necessary components are docker cp c547ea86f492:/WorkBench/WorkbenchProject/target (folder name). The folder created from extraction will be located in the directory where the command has been exectued. In the following example the folder will appear in the Desktop.
~/Desktop > docker cp c547ea86f492:/WorkBench/WorkbenchProject/target (folder name)
~/Desktop > ls
(folder name)

Adding Docker Images to Github (under construction)
