Why Docker is not native on Mac?
Docker can’t run natively since it uses linux kernel features not available on a mac. Apple would need to do a lot of work first to make it happen. If Docker for mac was running natively it would be more or less useless. Nobody deploys production code on MacOS hosts anymore.
Can Apple M1 run Docker?
You can download the Docker App for M1, which is in preview. As mentioned on the documentation page, there are some limitations currently related to HTTP proxy, VPN clients, and performance, but the Docker team is making progress fast.
What is the difference between bridge and host network in Docker?
Bridge networks are usually used when your applications run in standalone containers that need to communicate. See bridge networks. host : For standalone containers, remove network isolation between the container and the Docker host, and use the host’s networking directly.
What is Jenkins Docker plugin?

Network drivers. Docker’s networking subsystem is pluggable, using drivers. Several drivers exist by default, and provide core networking functionality: bridge : The default network driver. If you don’t specify a driver, this is the type of network you are creating.
Is Podman better than Docker?
Running containers with Podman is performed using the podman run command, which functions the same way as docker run . One of the main benefits of Podman compared to Docker is that Podman fully integrates with systemd by default. This enables Podman to run systemd within the container out of the box.
