To build:
docker build --tag localhost:32000/char .
To send to microk8s:
docker push localhost:32000/char
Run an ork:
docker run --env ENEMIES=127.0.0.1:8001 --env NAME=ork -p 8000:8080 --expose 8000 --rm -d char
Run an elf:
docker run --env ENEMIES=127.0.0.1:8000 --env NAME=elf -p 8001:8080 --expose 8001 --rm -d char
Then open the docs at 127.0.0.1:8001/docs and /attack the ork for 0 damage; watch the battle unfold.
Docker cleanup:
docker stop $(docker ps -a -q); docker rm $(docker ps -a -q)
docker images
docker rmi [ID of the old image]
Juju deploy:
if you have a char image called, say, char:latest in docker, do:
docker save char:latest | microk8s ctr image import -
now you can reference that image in microk8s; let's map it to char-image (or whatever you labelled your
image in metadata.yaml)
juju deploy --debug ./char-operator_ubuntu-20.04-amd64.charm --resource char-image=char:latest
