Bug or Misleading Docu: All docker images will be downloaded when the image tag is not specified #2545
Description
BUG
Setup: Python3.8: docker 4.2.0
When starting a clean postgres container using python docker sdk the docker sdk pulls all postgres images.
It would be helpful to update the docu mentioning that the version tag should be specified.
Or even more handy, introduce a default to the latest version?
Here is the code:
import docker
from docker.models.containers import Container
client = docker.from_env()
container: Container = client.containers.run(
image='postgres', remove=True, auto_remove=True, detach=True,
ports={'5432': '5432'},
environment=
[
'POSTGRES_PASSWORD=pwd',
'POSTGRES_USER=test',
'POSTGRES_DB=test'
])Bash output of 'docker images' before running the code:
REPOSITORY TAG IMAGE ID CREATED SIZEBash output of 'docker images' after running the code:
