Docker For Mac Doesnt Work When Android Emulator Running

DOCKER DOESNT WORK WHEN ANDROID EMULATOR RUNNING INSTALL VIRTUALBOX AND

We have an aarch64 server (16 4 cores), with 18 emulator instances running.Unfortunately, this means Docker only runs on Linux. Well, I come back to this post with my results. Forums.docker.com/t/cant-using-docker-for-mac-with-android-emulator-haxm/8939Apart from that since emulator is backed by qemu there should be no additional challenges to run arm image on arm host (in comparison to run x86 image on x86 host). In Linux, these aren't VMs and are light weight user-land separations that use things like cgroups and lots of really special kernel modules for security.I kept getting this error when running Android Emulator in Android Studio. There's no issue with VirtualBox machines - they run fine, but Android emulator gives aforementioned errors 'emulator: Failed to sync vcpu reg emulator: Failed to sync HAX vcpu context' and does not start or stops or crashes, so you can't use Android Studio.Docker uses LXC containers. I have the same issue immediately after upgrade from 4.3.28 to 4.3.30.

It can't, even on Mac which has a (not really) *NIX-sh base. It's not actually running Docker natively. For this test, you can take advantage of the Android.Even with this update.you still need to run in a virtual machine. In Windows/Mac, you still need to run in a virtual machine.An instrumentation unit test is a unit test that is executed on an actual machine or emulator.

With Docker, each app should be its own container and you link the containers together using things like Docker compose or running them on CoreOS or Mesos.In my work with Docker, I'm not sure how I feel. With VMs, you'd typically want some type of configuration management (Puppet, Ansible, Chef, etc.) that sets up apps on each VM/server. Docker containers are meant to handle one application (that it runs as root within its container as the init process. I haven't tried it.So even in Windows/Mac, all your containers do run in one VM (where as with traditional stuff you mentioned, you'd need a VM for each thing). I'm not sure.I've only looked at the Readme. I _think_ FreeBSD has native Docker support with some custom kernel modules.

Writing one yourself with docker-py is horribly difficult because of image dependencies).Oh and images. A docker command to do this is still a Github issue. CoreOS prunes these at regular intervals. After a while you get a shit ton of images that just waste space you're not using. CoreOS is pretty neat and I wouldn't use docker in production without it or another container manager (the docker command by itself still cannot prune unused images. Right now, Docker doesn't have any blaring security holes and LXC has increased security quite a bit.

I think it's better to build packages (rpms, debs). I find it lazy in some ways. I think.I haven't looked into that yet).Docker is. It's actually kind of interesting and allows for base image updates to fix security issues (although you still need to rebuild your containers against the new images. That's a whole thing I don't want to go into, but look it up.

Dockerignore file and I can never really be sure from one build to the next that I haven't screwed it up somehow. We're all of us running around with our pants down because we think Docker is taking care of this stuff but it's merely a bunch of features that look like they should be fit for that purpose but aren't.And this is why I am stuck with a separate build and package phase, because I have to have that separation between the data available at build time and what ends up shipped, but even there I'm pretty sure I'm making mistakes, due to some of the design decisions Docker made thinking they were helping but actually made things worse.For instance, there's no really solid mechanism for guaranteeing that none of your secret files end up in your docker image, because they decided that symlinks were forbidden. O_oI think you just proved my point. I've only made fun of it in the past, but now I work for a shop that uses it in production. I'm trying to actually like Docker. You throw your containers on CoreOS/Mesos and use Consul for environment variables and you can have a pretty smooth system.I dunno.

I _think_ FreeBSD has native Docker support with some custom kernel modules. Not even Linux.special Docker Kernel Linux (all the features they need are in the stock Kernel tree, but it's still a lot of modules).Almost all modern distros have support for all of the modules required to run Docker.> In Linux, you can just go to localhost. LXC is not supported anymore and it was always a hacky execdriver.> In Linux, these aren't VMs and are light weight user-land separations that use things like cgroups and lots of really special kernel modules for security.They're kernel-space separations since the kernel understands namespaces (though it doesn't understand the concept of a container and some things aren't namespacrd).> Unfortunately, this means Docker only runs on Linux. It's a backlash waiting to happen.Nope, we've been using our own implementation of a container runtime for 2 years (libcontainer).

Right now, Docker doesn't have any blaring security holes and LXC has increased security quite a bit.Again: Docker doesn't and hasn't used LXC for quite a while. LXC containers have had a lot of security issues. It's discouraged for scalability reasons to stuff your database and front-end in the same container because then it's hard to spin up more than one front-end connected to the same backend.> In my work with Docker, I'm not sure how I feel. You can run a proper init inside your container (in fact it's recommended), and run many processes inside the same container. Cause wtf?).All machines have a single process running as root as the init. I haven't tried it.> So even in Windows/Mac, all your containers do run in one VM (where as with traditional stuff you mentioned, you'd need a VM for each thing).Actually, recent versions of Docker can run as a daemon on Windows using some proprietary features I don't care about.> Docker containers are meant to handle one application (that it runs as root within its container as the init process.

Docker uses images to build things up like building blocks. Besides, you should be using engine-api.> Oh and images. Writing one yourself with docker-py is horribly difficult because of image dependencies).Sure, it's not a single command but it isn't impossible to do and doesn't require docker-py. A docker command to do this is still a Github issue. CoreOS prunes these at regular intervals. There is a concern on the kernel side that they don't appear to care about going the Zones or Jails route: actually making the kernel aware about containers so that it can properly namespace things.> After a while you get a shit ton of images that just waste space you're not using.

Docker Doesnt Work When Android Emulator Running Install VirtualBox And

The filesystem sharing maps OSX volumes seamlessly into the Linux container and remaps MacOS X UIDs into Linux ones (no more permissions problems), and the networking publishes ports to either `docker.local` or `localhost` depending on the configuration.A lot of this only became possible in recent versions of OSX thanks to the Hypervisor.framework that has been bundled, and the hard work of mist64 who released xhyve (in turn based on bhyve in FreeBSD) that uses it. You just drag-and-drop the Mac application to /Applications, run it, and the Docker CLI just works. There would be a network endpoint on your Mac that pointed at the Linux VM, and the two worlds are quite separate.Docker for Mac is a native MacOS X application that embeds a hypervisor (based on xhyve), a Linux distribution and filesystem and network sharing that is much more Mac native. Previously in order to run Linux containers on a Mac, you needed to install VirtualBox and have an embedded Linux virtual machine that would run the Docker containers from the Mac CLI. I think.I haven't looked into that yet).There's also tools like zypper-docker to allow for hot-patching of images.Let me explain Docker for Mac in a little more detail. It's actually kind of interesting and allows for base image updates to fix security issues (although you still need to rebuild your containers against the new images.

Inside the application is also the latest greatest Docker engine, and autoupdates to make it easy to keep uptodate.Although the app only runs Linux containers at present, the Docker engine is gaining support for non-Linux containers, so expect to see updates in this space. We've also used some unikernel libaries from MirageOS to provide the filesystem and networking 'semantic translation' layers between OSX and Linux.
