brucemack / hello-docker

A simple project to illustrate the mechanics of a Python FastAPI server deployed using Docker

Docker Commands Used

Context control:

    docker context ls
    docker context create --docker host=tcp://192.168.8.102:2375 pi4
    docker context use pi4

Build Container image into local registry:

    docker build -t myimage .
    docker image ls

Run container from local registry:

    docker run -d --name mycontainer --restart=unless-stopped -p 8080:80 myimage

Listing running containers:

    docker container ls

Stop container:

    docker container stop mycontainer

Tag the container, uplaod it, and run it from Dockerhub:

    docker login
    docker tag myimage:latest brucemack/myimage:1.0
    docker push brucemack/myimage:1.0
    docker run -d --name mycontainer -v myvol:/app -p 8080:80 brucemack/myimage:1.0

Remove container and force a stop:

    docker container ls
    docker container rm -f mycontainer

Cleanup:

    docker system prune

Create a volume and start a container with it.

    docker volume create myvol
    docker volume inspect myvol
    docker run -d --name mycontainer -v myvol:/app -p 8080:80 myimage

Looking at the volume using a special-purpose container:

    docker run --rm -i -v=myvol:/app busybox ls /app        
    docker run --rm -i -v=myvol:/app busybox cat /app/data.txt
