  .

docker buildx build --load \
  -t "${DOCKER_REPOSITORY_NAME}/${DOCKER_IMAGE_NAME}:${DOCKER_IMAGE_TAG}" \

  ENV_VARS+=" --env=TZ=$(cat /etc/timezone)"
}

prepare_docker_timezone

docker run --rm -it \
  --name "${DOCKER_IMAGE_NAME}" \
  ${ENV_VARS} \
  "${DOCKER_REPOSITORY_NAME}/${DOCKER_IMAGE_NAME}:${DOCKER_IMAGE_TAG}" "$@"

You can stop the running container like this:

#!/usr/bin/env bash

DOCKER_IMAGE_NAME="distroless-caddy"

docker stop  \
  "${DOCKER_IMAGE_NAME}"

Start

If you run the container without --rm you can start it again like this:

#!/usr/bin/env bash

DOCKER_IMAGE_NAME="distroless-caddy"

docker start \
  "${DOCKER_IMAGE_NAME}"
