It allows us to closely replicate the internal, automated testing, user acceptance testing and production platforms.

The performance of the file system when using volume mounts.

This article has been recently updated, please see the amendments at the bottom.

As developers we have been through a few different development environments in our time.

Moving from Vagrant to Docker was a blessing, although one thing that hit us hard was the performance of Docker on Mac, specifically the file system performance.

If you made a change in your IDE, it would be replicated into the container (somehow), and you could then serve the updated content through your application.

This meant that the host file system was the last to know about the changes, but this was a good thing (generally) as it meant your application would run fairly smoothly inside the container.

Now, IO peformance is not the only element of the overall app performance, but Ill take this performance improvement over delegated anyday.

Now he finds himself more working with the infrastructure of cloud computing specifically, AWS and Docker.

If you are a Mac user, you may experience that the connection to docker is extremely slow.

The slow performance sometimes cause connection timeout (mostly 30 seconds).

But I prefer another workaround which allow you to update the files directly read by docker container.

What I want to do is to change the path as a symbolic link which points the host path on your mac.
