Memory: By default, Docker for Mac is set to use 2 GB runtime memory, allocated from the total available memory on your Mac. To increase RAM, set this to a higher number; to decrease it, lower the number. Swap: Configure swap file size as needed. The default is 1 GB. Docker is an open-source project to easily create lightweight, portable, self-sufficient containers from any application. The same container that a developer builds and tests on a laptop can run at scale, in production, on VMs, bare metal, OpenStack clusters, public clouds and more.

• Binaries: • Source code: 2.0 Website Docker is a that performs, also known as 'containerization'. It was first released in 2013 and is developed by Docker is used to run software packages called '. Containers are isolated from each other and bundle their own application, tools, and configuration files; they can communicate with each other through well-defined channels.

All containers are run by a single and are thus more lightweight than. Containers are created from 'images' that specify their precise contents. Images are often created by combining and modifying standard images downloaded from public repositories.

Also became involved as an independent collaborator. [ ] Docker represents an evolution of dotCloud's proprietary technology, which is itself built on earlier open-source projects such as. [ ] [ ] The software debuted to the public in Santa Clara at in 2013. Docker was released as open source in March 2013.

On March 13, 2014, with the release of version 0.9, Docker dropped LXC as the default execution environment and replaced it with its own libcontainer library written in the programming language. Adoption [ ] • On September 19, 2013, and Docker announced a collaboration around,,. • In November 2014 Docker container services were announced for the (EC2).

• On November 10, 2014, Docker announced a partnership with. • On December 4, 2014, announced a strategic partnership with Docker that enables Docker to integrate more closely with the IBM Cloud. • On June 22, 2015, Docker and several other companies announced that they are working on a new vendor and operating-system-independent standard for software containers. • As of October 24, 2015, the project had over 25,600 stars (making it the 20th most-starred GitHub project), over 6,800 forks, and nearly 1,100 contributors. • In April 2016, Windocks, an independent ISV released a port of Docker's open source project to Windows, supporting Windows Server 2012 R2 and Server 2016, with all editions of SQL Server 2008 onward. • A May 2016 analysis showed the following organizations as main contributors to Docker: The Docker team,,,,,,. • On October 4, 2016, Solomon Hykes announced as a new self-healing container infrastructure effort for Docker container environments.

• A January 2017 analysis of profile mentions showed Docker presence grew by 160% in 2016. The software has been downloaded more than 13 billion times as of 2017. Technology [ ]. Docker can use different interfaces to access virtualization features of the Linux kernel. Docker is developed primarily for, where it uses the resource isolation features of the such as and kernel, and a such as and others to allow independent 'containers' to run within a single Linux instance, avoiding the overhead of starting and maintaining (VMs).

Make sure you don't have any formatting going down those columns (e.g., cell borders applied to an entire column). Right-click the row header area and click Delete. Select the bottom row (1048579, I believe) and a bunch above it, about 20-30, whatever is visible on the screen. Grab the scroll bar and drag it all the way to the bottom. How to delete multiple rows in excel.

The Linux kernel's support for namespaces mostly isolates an application's view of the operating environment, including process trees, network, user IDs and mounted file systems, while the kernel's cgroups provide resource limiting for memory and CPU. Since version 0.9, Docker includes the libcontainer as its own way to directly use virtualization facilities provided by the Linux kernel, in addition to using abstracted virtualization interfaces via,. Building on top of facilities provided by the (primarily cgroups and namespaces), a Docker container, unlike a virtual machine, does not require or include a separate operating system. Instead, it relies on the kernel's functionality and uses resource isolation for CPU and memory, and to isolate the application's view of the operating system. Docker accesses the Linux kernel's virtualization features either directly using the libcontainer library, which is available as of Docker 0.9, or indirectly via, (Linux Containers).
