This test uses a standard Docker MySQL image without tweaks, and an image with sysbench installed. Does It Really Work? I created a to check this. Things will get a lot faster when you type those few lines into your terminal: $ cd ~/Library/Containers//Data/database/ $ git reset -hard HEAD is now at cafabd0 Docker started $ cat 64-linux/disk/full-sync-on-flush true $ echo false > 64-linux/disk/full-sync-on-flush $ git add 64-linux/disk/full-sync-on-flush $ git commit -s -m 'Disable flushing' Disable flushing 1 file changed, 1 insertion(+), 1 deletion(-) Actually, someone even placed to make things easier. While reading about Docker issues on GitHub, I found a solution provided. In this case, you may decide to disable this. If you have a Macbook, even power loss isn’t a threat. Actually, this makes sense - if you decide to setup a database inside Docker for Mac on a production environment In most cases, though, you’ll be using your machine for dev purposes where you don’t care to recreate the database from fixtures. This will guarantee that during power loss or any unexpected event your data will be safe. Applications, such as databases, that require a strict ordering of writes should use F_FULLFSYNC to ensure that their data is written in the order they expect.” In short, to keep our data safe, every change made in the database needs to be stored on disk in an exact order. The F_FULLFSYNC fcntl asks the drive to flush all buffered data to permanent storage. At least, as long as you don’t try to do any heavy database work.ĭocker for Mac and Full Sync on Flush Issue First, let’s look at MacOS: “For applications that require tighter guarantees about the integrity of their data, Mac OS X provides the F_FULLFSYNC fcntl. If you are – for example – a Java developer who uses Docker to run compiled JAR, you may even not notice the difference. Things won’t be as close to bare metal as they are in Linux. Because of this, you need to allocate CPU cores and RAM for the VM. To make all this possible, a light Alpine Linux image is fired up underneath with xhyve MacOS native virtualization. It gives you the whole Docker API available from the terminal, even though Docker itself wasn’t created to work on Macs. Docker for Mac is a pretty smart invention. Have you heard how great Docker is and want to give it a? Did you think that you could just take your Docker Compose file, launch your project, and have everything work out for you? Are you a Linux user who switched to Mac when you saw that Docker is now available as a native Mac app? Best antivirus software for mac os x.
