Why Use Docker For On Mac Is Set

By default, Docker Desktop for Mac is set to use half the number of processors available on the host machine.

Consistency cache tuning in Docker follows a user-guided approach.

Historically, these components were installed on our machines using Homebrew, a virtual machine, or some other application like MAMP.

Weve also moved most of our pre-existing projects to a Dockerised setup too, meaning a developer can begin working on a project without having to install any prerequisites.

It gives the container a view of the hosts file system In literal terms, pointing a particular directory in the container to a directory on your Mac.

Any writes in either the host or container are then reflected vice-versa.

In contrast, there is a much bigger overhead on MacOS and other platforms in keeping the file system consistent which leads to a performance degradation.

This is a native MacOS application, which is bundled with an embedded hypervisor ( HyperKit ).

However, unlike Docker on Linux, any file system changes need to be passed between the host and container via Docker for Mac, which can soon add a lot of additional computational overhead.

Docker defaults to a consistent guarantee that the host and containers file system reflect each other.

Every time a write happens, the data is flushed to all participants of the mounts view.

There may be delays before writes on a host are available to the container.

However, certain workloads could require increased consistency.

I personally default to delegated, as generally our bind-mounted volumes contain source code.

Data is only changing when I hit save, and its already been replicated via delegated by the time Ive got a chance to react.

It has a good reason, which states that a system that was not consistent by default would behave in ways that were unpredictable and surprising.

Every time we start a Docker container, its a fresh instance of itself.

Docker would then pull Composer packages from an internal cache instead of the web.

Quite a simple performance tweak would be to increase the RAM limit available to Docker.

It wont hurt anything to give Docker Desktop an extra 2GB of RAM, which will greatly improve those memory intensive operations.

Docker will be synchronising a lot of file system events, and actions between host and container.
