As such, cached typically improves the performance of read-heavy workloads, at the cost of some temporary inconsistency between the host and the container. The cached configuration provides all the guarantees of the delegated configuration, and some additional guarantees around the visibility of writes performed by containers. In situations such as NFS asynchronous mode, if a running container with a delegated bind mount crashes, then writes may be lost.
For directories mounted with delegated the container’s view of the file system is authoritative, and writes performed by containers may not be immediately reflected on the host file system. The delegated configuration provides the weakest set of guarantees. According to official Docker documentation (April 2020): Delegated These two methods are “cached” and “delegated”. The problem is, that in default configuration, volumes always ensure data consistency between host and containers: if you save something on host or container, changes are immediately reflected on second side, it also protects against data loss.ĭocker provides two methods for caching and speed up: both doesn’t provide such consistency but can improve performance a lot.

It means, it’s also performance degradation, especially on Windows and Mac (it can work much better on Linux with native kernel and many system files). But, it’s I/O, sometimes light, sometimes heavy and intensive. There are plenty of use cases for volumes. We use a lot of volumes typically – to share config, to share code, to provide backups, to link some resources. If you use Docker and you have ever experienced any performance issues, you probably know, what is volumes caching.
This post is about volumes cachings methods – we can use them to speed up Docker in any platform and should be used, if we can do this. It’s ok and necessary, but always causes some performance degradation, especially on networking and any I/O operations. Docker for Mac and Docker of Windows uses small virtual machine in the middle, between your host and your containers. From my perspective, the biggest is performance. Unfortunately, I use it on Mac, and it has some big drawbacks. It has a lot of advantages and I have been using it very actively for some time. Let’s assume that we have the user ubuntu with the id 1001 (which you can find using the command id).Docker is amazing tool and can make developer work simpler, faster and more efficient.

This is far from ideal as with every git update you have permission issues and need to fix them again. To overcome deployment issues, thaJeztah explains that you would need to set the correct permissions every time on Linux. This is by design as explained by thaJeztah. File system permissions are not automatically resolved. Permission issues are resolved automatically. In both MacOS and Windows, Docker runs as a virtual machine with Linux. So far, all is good with MacOS and Windows (if you use the latest version). We recommend updating to the newer applications, if possible. Docker Toolbox is for older Mac and Windows systems that do not meet the requirements of Docker Desktop for Mac and Docker Desktop for Windows. Therefore, updating to Docker Desktop is recommended to prevent weird issues like not seeing shared volumes. The reason why I mention this, is because Toolbox does not have proper support for sharing volumes. Because it was Windows 7, for some reason Docker Desktop did not install.

However, one of our customers used Windows 7 ( which is EOL…) and used Docker toolbox. When you use the Docker Desktop version, it is most likely that you won’t run into issues. Good to know: Docker uses Hyperkit to create a virtual machine on your Mac. There are no permissions errors nor modifications required to a regular docker file or the docker-compose file. performance issues when sharing volumes), it does work. While it certainly has its challenges (e.g. I develop using Docker containers on MacOS. The example files for making your docker-compose.yml cross-platform compatible are hosted on Github.

In this blog, I will explain our experience of how to make your docker-compose cross-platform compatible on MacOS, Windows and Linux. In practice, Docker is not that easy when you use it cross-platform. You can use the containers everywhere, so it should be cross-platform. Docker is supposed to be a cross-platform tool.
