Getting Started

1. Install Docker CE
2. Build the Docker Image using build args

• See the Build an image section below.
• Once built, an image can be dispatched to N containers
• There is not hot loading set up. Any changes, force a container rebuild
  • To keep an old version of a container, increment the tag (currently 0.1)
• Builds and containers can get heavy
  • Remove old containers when they finish running
  • Remove old images that have been deprecated

3. Notes

• The host machine's localhost is normally 172.17.0.1 within a running container
• The docker IP is normally 172.17.0.2

Using Docker

Build an image:

docker build --build-arg MYBUILDARG="ABCDEF1234567890" -t myimage:0.1 .

Run interactive terminal in image

docker run -it myimage:0.1 bash

Note: Very helpful to prep unix os based builds

Run a solver given scenario_ids

• To run a container and remove it once it has completed its job:

docker run --rm myimage:0.1 python3 execute.py

• To save the container state after finishing its job:

docker run myimage:0.1 python3 execute.py

List Containers

docker ps -a

Remove Containers

docker rm <container hash>

Remove All Containers

docker rm $(docker ps -a -q)

List Images

docker images -a

Delete Image

docker rmi <name>:<tag>

docker rmi <image hash>

Delete All Images

docker system prune -a
