Dinghy-http-proxy works great with Docker for Mac, and because DFM exposes ports to the host, you don't need to know the VM IP, just use the linux instructions to. Docker Desktop is an application for MacOS and Windows machines for the building and sharing of containerized applications and microservices. Docker Desktop delivers the speed, choice, and security you need for designing and delivering these containerized applications on your desktop.

DinghyDocker on OS X with batteries included, aimed at making a more pleasant local development experience.Runs on top of. Faster volume sharing using NFS rather than built-in virtualbox/vmware file shares. A medium-sized Rails app boots in 5 seconds, rather than 30 seconds using vmware file sharing, or 90 seconds using virtualbox file sharing. Filesystem events work on mounted volumes. Edit files on your host, and see guard/webpack/etc pick up the changes immediately. Easy access to running containers using built-in DNS and HTTP proxy.Dinghy creates its own VM using docker-machine, it will not modify your existing docker-machine VMs.Dinghy runs as a wrapper around docker-machine, shelling out to create the VMand using daemons to start the various services such as NFS and DNS.
PROJECT STATUSTL;DR I am still actively maintaining Dinghy, making small improvements and fixing issues. But it's unlikely that there will be any large new development efforts unless somebody else wants to step up and take them on. Docker for Mac is a great option for most, if not all, people.When we started the Dinghy project, Docker for Mac did not exist and there wasn't a great option for using Docker on MacOS easily with high-performance file sharing.These days, Dinghy still has a performance advantage over Docker for Mac in some use cases where you are sharing lots of files from a host volume.
But for the most part, you are fine just using Docker for Mac, you don't necessarily need Dinghy. There is a lot of discussion around the pros and cons in.Dinghy also includes a HTTP(S) proxy and DNS server that can make developing web apps easier, especially if you switch between projects frequently. This proxy can now be used without Dinghy on top of Docker for Mac, see.
FAQ and solutions to common problemsBefore filing an issue, see the. Upgrading from vagrantIf you previously used a version of Dinghy that ran on top of Vagrant,. InstallFirst the prerequisites:.
OS X Yosemite (10.10) or higher. Docker and Docker Machine. These can either be installed with Homebrew ( brew install docker docker-machine), or using a package such as the Docker Toolbox. A Virtual Machine provider for Docker Machine.
Currently supported options are:. installed with.
This is the recommended option, it is simpler to setup and appears to be more stable overall. Version 5.0+ is strongly recommended. installed with.Then: $ brew tap codekitchen/dinghy$ brew install dinghyYou will need to install docker and docker-machine as well, either via Homebrew or the official Docker package downloads. To install with Homebrew: $ brew install docker docker-machineYou can specify provider ( xhyve, virtualbox, vmware or parallels), memory and CPU options when creating the VM. See available options: $ dinghy help createThen create the VM and start services with: $ dinghy create -provider xhyveOnce the VM is up, you'll get instructions to add some Docker-relatedenvironment variables, so that your Docker client can contact the Dockerserver inside the VM. I'd suggest adding these to your.bashrc orequivalent.Sanity check!
$ docker run -rm hello-worldCLI Usage. $ dinghy halt$ export DINGHYHOSTMOUNTDIR=/code/projects$ export DINGHYGUESTMOUNTDIR=/code/projects$ dinghy upThere is an open issue for persisting this in the /.dinghy/preferences.yml file, and allowing multiple dirs to be exported: Custom certficate directoryYou can change the default certificates directory /.dinghy/certs by setting the DINGHYCERTPATH environment variable before starting the dinghy VM. This is useful if you have a custom NFS Mount location and your home directory is no more shared, in bash. $ dinghy halt$ export DINGHYCERTPATH=/code/projects/certs$ dinghy up UpgradingIf you didn't originally install Dinghy as a tap, you'll need to switch to thetap to pull in the latest release: $ brew tap codekitchen/dinghyTo update Dinghy itself, run: $ dinghy halt$ brew upgrade dinghy unfs3$ dinghy upTo update the Docker VM, run: $ dinghy upgradeThis will run docker-machine upgrade and then restart the dinghy services.
PrereleasesYou can install Dinghy's master branch with: $ dinghy halt$ brew reinstall -HEAD dinghy$ dinghy upThis branch may be less stable, so this isn't recommended in general. Built on.
Docker on Linux runs a separate userland on the same main kernel. Docker on Mac has to run a separate kernel using virtualization. The virtualization coming with Docker for Mac is not optimized (yet?). You can use Virtual Box, VM Ware or Parallels as an alternative (although the last two cost some money). All of them integrate well with Docker machine.I am using Docker with Parallels. It's running really fast for my use cases, with no issues reading disc IO and network IO.
But you should benchmark your workload, before buying anything. I'm afraid I haven't been able to get my point across.Docker for Mac (after some optimization) is probably usable. VM Ware, VirtualBox etc. All do a pretty good job nowadays.Docker (on Linux) is different because it uses container-virtualization. This isn't really a new concept (greetings to the freeBSD people). Docker just made it user-friendly and created an ecosystem around it.My point is, that Docker is built around the idea of using containers.
Docker on Mac can't use containers.It might still have it's use cases since you're still able to use the Docker ecosystem, but as long as it has to use this additional layer, it is really more like all the other virtualization solutions out there and not like Docker.If you are experiencing a faster execution than on bare metal, that's some interesting anecdotal evidence. But usually there is a performance loss when running your program inside a virtual environment.It's like I'm saying a car is faster than a bicycle and you're saying that a bike can be faster than a car under certain conditions and that any place you're going to is close by so it doesn't make a difference anyways. You're not wrong. We're just talking about different things.
In most productive scenarios you will be running containers inside a VM. Just think of AWS. The key is running multiple containers in the same VM.Usually the penalty you pay for the VM is a few percent performance (low single digit number). This it's easily offset by other factories: RAM, disc IO, latency, cache usage, available CPU cores, etc.Some hypervisors provide RAM compression (instead of swapping) and duplication. Linux usually doesn't provide this.
This can lead to more available RAM and less swapping inside the VM, leading to faster response times or more parallel sessions. Our in other words: more performance. You could do the same with a specially patched kernel.This it's only one example, where VM features can lead to better KPIs regarding things usually attributed as 'performance'. In most productive scenarios you will be running containers inside a VM.
Just think of AWS. The key is running multiple containers in the same VM.absolutely. In a huge environment like this. But that's not really a usecase for 'Docker on Mac'Some hypervisors provide RAM compression (instead of swapping) and duplication. Linux usually doesn't provide this.again: I'm not trying to say that you should avoid virtualization or even that the loss in performance is particularly relevant for some local test environment running on a laptop. I just wanted to say that on a Mac, performance is not so much a matter of 'when will Docker further optimize it?'
A 'real' Docker for Mac will ppl take a few years. I don't know how much involvement apple has had with libcontainer and what plans they have for their kernel. Docker for Mac is helping people getting started. It's not for production yet and probably never will be. It's probably not even fit for development.It's good practice to mimic your production as closely as possible in your development environment. When you are running Docker on CoreOS inside a VM in production, it's a good idea to do the same in development.
If your network has a certain bandwidth and a certain latency in production, it's a good idea to configure the network conditioner on the hypervisor on your development machine with the same conditions.Docker for Mac cannot do this now. I doubt that it will ever be able to do this. It's for small experiments and to play around with Docker a little bit.
I don't see any serious effort to get it to same level as Parallels or VM Ware Fusion. It would be much more economical to add the missing features to Virtual Box.But hey, if would be very glad to be wrong with that!
This would be a very pleasant surprise.
