Docker Is Slow Code Into Containers

The fact of the matter is, Docker for Mac has terribly slow IO performance compared to on Linux machines.

Docker Is Slow Code Into Containers

Developing with docker under OSXWindows is a huge pain, since sharing your code into containers slows down the code-execution.

To show how to set up the docker-sync with our application lets take an example of a Rails application.

In my rails application I have a docker-compose.yml of the following configuration: First, you need to install the docker-sync gem: sudo gem install docker-sync Then you need to create docker-sync.yml.

If you want to start the sync process first and then start the containers separately you can do it with the following commands: docker-sync clean docker-sync start docker-compose up After setting up docker-sync you may face the issue that your main application container tries to get up and running before the database container spins up.

If this happens then your main application container will not get started.

To prevent this we can make the following change to your docker-compose.yml file.

This configuration is optional it all depends on how you set up your dependent containers in your docker-compose.yml file.

By using this configuration the main application container wont start unless the database container has started.

This setup is working pretty well for us and enables us to run Docker on a Mac like a charm Better Programming Advice for programmers.
