While Docker can run natively on Linux hosts, a small Linux VM is necessary to provide the virtualization services on Mac OS and Windows systems.

Docker ( ) is an open source project that provides tools to setup and deploy Linux software containers. Linux has supported OS-level virtualization for several years. In addition, multiple containers share a single OS kernel, thus saving considerable resources over multiple VMs.
Containers differ from traditional virtual machines (VMs) in that the resources of the operating system (OS), and not the hardware, are virtualized. The host service is accessed and authenticated through the HTTP/HTTPS port, greatly simplifying the configuration necessary to support cloud-based platforms.Ī software container packages an application with everything it needs to run, including supporting libraries and system resources. With a browser-based solution, we also have access to web-based authentication protocols such as Oauth2 , which allows for authentication using an email account. Most importantly, GUIdock-VNC also facilitates the deployment of Docker applications on the cloud. This is a major advantage as the users of bioinformatics workflows are not necessarily technically trained in configuring computer systems.
#Tigervnc docker install
The browser transparently downloads the noVNC client from the container and becomes the terminal, thus eliminating the need for the user to configure and install separate software. Modern browsers can use the HTML5-based noVNC client to display the screen locally. noVNC is a browser-based VNC client implemented using HTML5 Canvas and WebSockets . This can actually be less chatty than the X11 methodology, which is constantly sending display commands. Bandwidth requirements are minimized by only transferring the differences between the current screen and the last screen. Instead of transferring commands and allowing a local client to render the graphics, VNC transfers a pre-rendered screen. GUIdock-VNC uses the Virtual Network Computing (VNC) protocol to render the graphics. Here we describe GUIdock-VNC, which implements an improved browser-based solution that does not require the user to map ports, configure firewalls, or install any additional specialized software. In addition, on systems such as Windows, where there is no native X11 support, additional client software must be installed by the user to render the X11 graphics locally. While the X11-based display method can be conveniently deployed in the local environment by exposing a file socket from a container, deploying the image on a cloud and accessing it remotely is non-trivial. We have previously described and implemented GUIdock-X11 , an X11-based methodology for portably supporting GUI applications in containers on different platforms. Many bioinformatics pipelines have a component that requires a graphical user interface (GUI) that can potentially limit the portability of the Dockerized workflows as different platforms use different methodologies to render the GUI. For example, BioShadock , BioDocker and Bioboxes are two frameworks aimed at reproducibly deploying bioinformatics workflows using Docker containers. Software container technology such as Docker ( ) package the dependencies with the software and provide a method to reproduce these complex pipelines on multiple hardware and cloud platforms. Modern workflows in computational fields such as bioinformatics consist of multiple software implementations, each with their own set of dependencies. We benchmarked our container implementation on various operating systems and showed that our solution creates minimal overhead. Conclusions: As a proof-of-concept, we demonstrated the utility of GUIdock-noVNC in gene network inference. In addition, GUIdock-VNC uses the Oauth2 authentication protocols when deployed on the cloud.
We also present a minimal image builder that can add our proposed graphical desktop sharing system to any Docker packages, with the end result that any Docker packages can be run using a graphical desktop within a browser. GUIdock-VNC uses the Virtual Network Computing protocol to render the graphics within most commonly used browsers. Results: We present a container tool called GUIdock-VNC that uses a graphical desktop sharing system to provide a browser-based interface for containerized software. However, Docker is a command line–based tool, and many bioinformatics pipelines consist of components that require a graphical user interface. Background: Software container technology such as Docker can be used to package and distribute bioinformatics workflows consisting of multiple software implementations and dependencies.
