Docker

Docker

Docker is an open-source project for automating the deployment of applications as portable, self-sufficient containers that can run on the cloud or on-premises.

Why we use it

We use docker as a way to have a portable, replicable environment to conduct development on the vision system without having physical access to the bike or any of its corresponding SoCs.

Docker on Linux

• To install:
  • For Ubuntu:
    • sudo apt-get install docker
  • For Red Hat:
    • sudo yum install docker
  • For Fedora:
    • sudo dnf install docker -y
  • For Arch:
    • sudo pacman -S docker

• Starting the docker daemon (on most distros):
  • sudo systemctl enable docker.service

Docker With Pain (Windows)

Use the “edge” version or else it won’t like the windows version

Docker on Mac

Pretty straightforward installation. There is a tutorial you can follow after installation.

Commands

• To run a docker image in a container/volume:
  • docker run -it --rm --mount source=SOURCE,destination=/DESTINATION IMAGE

• • For example, to run an image anything in a container autobike:
    • docker run -it --rm --mount source=autobike,destination=/autobike anything

• To create a new container:
  • docker create [OPTIONS] IMAGE [COMMAND] [ARG...]

• To name a docker image:
  • docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]

• To see your docker images:
  • docker image list

• To see docker volumes:
  • docker volume list

• To delete a docker image list:
  • docker image rm [OPTIONS] IMAGE [IMAGE...]

When using a container, remember to store the code inside the folder of the container so that changes will be saved.
