Docker Storage Install Docker On

Stale issues will be closed after an additional 30d of inactivity.

And just like k7 said, encode the X-Amz-Credential parameter can fix this.

It might also be an issue in github.comdockerdistribution it is not clear.

Requests to the S3 instance are missing encoded in X-Ams-Credential query parameter, and fails authentication.

Let me know if you need an account to test against our repo.

If the problem lies elsewhere then docker for mac, please advise.

To check this, run the following command in your terminal: docker-machine --help Now you know how everything works, its time to set everything up.

Although I try to cover all steps in detail, it does help if you have experience with Linux, VirtualBox and Docker.

Background Some services might run more efficient in docker depending on the storage driver.

Docker has a pluggable system that allows various storage drivers to be used.

Because of this some storage drivers perform a bit better than others.

Performance bottlenecks or incompatibility for your service might be caused by your current storage driver.

Its also possible that your storage driver is incompatible or less efficient because of the backing file system.

When docker was first created, it was running on Ubuntu using AUFS as its storage backend.

Growing at a fast pace, docker began gaining interest from other companies that wanted to use it.

Many of these companies were using Red Hat Enterprise Linux (RHEL), but because AUFS was not part of the upstream mainline linux kernel, RHEL did not include this either.

After some research by the brilliant people behind RHEL, they decided to not include the AUFS file system into RHEL, yet they decided to develop their own storage backend based on the existing Device Mapper technology.

Docker on OSX Because of the namespace and cgroup technology leveraged by Docker, Docker is not natively supported by OSX.

Namespacing and cgroups are Linux kernel features, OSX however is based on the unix kernel.

To allow Docker to work on non-linux operating systems, docker uses a virtual machine (VM) based on Linux.

The docker CLI tool on OSX executes all commands inside this VM.

Docker Storage Install Docker On

When you install Docker on OSX, Docker manages the installation of a VM within VirtualBox.

This VM runs the boot2docker operating system which is a minimal Linux distro specially crafted for docker.

Throughout this tutorial, Im going to refer to these external VMs running the Docker Engine, Docker Machines.

Using the device mapper storage driver So now that you have some background information on what storage drivers are and how docker works on OSX, lets get into the device mapper storage backend.

Like explained earlier, the device mapper storage driver is a additional storage backend developed by the RHEL developers.

And included in Ubuntu 12.04, Ubuntu 14.04, and Debian.

It was however not included in the boot2docker distro, which is used as default by Docker on both OSX and Windows.

So to use the storage driver, were going to setup a separate Docker Machine that runs CentOS, and connect this to your host OS.

To setup and control different Docker Machines either locally on VMs or externally through the cloud docker created a extra tool called Docker Machine.
