Hello Prefect Team, I’m deploying a flow with the Docker infra using the

docker:dind

(docker -in-docker) image. The ideia is to run containers inside the flow using the

docker

sdk. Using the

/var/run/docker.sock

volume is not an alternative for my use case. It seems that the only thing stopping me at this point is that I cannot set the

privileged

flag in the

prefect.infrastructure.DockerContainer

abstraction. As shown in the docker-compose below, it is required for running the

docker:dind

container.

Copy code

services:
  dind:
    image: docker:dind
    privileged: true

Could this option be added to Prefect? Happy new year for everyone 😄

If I am not mistaken, prefect uses the method

create_container

docker.api.container.ContainerApiMixin

to create the containers. This method accepts the

host_config

argument, which can be set by using the method

create_host_config

of the same class, which accepts the

privileged

argument.

Hi! We’re waiting for a design to be proposed to expose host_config options: https://github.com/PrefectHQ/prefect/issues/7301

I had just create an issue for this topic, fell free to close it, since this other issue might include my request: https://github.com/PrefectHQ/prefect/issues/8019
