Containers

Containers are a way to separate and isolate processes or groups of processes in Linux distributions

Containers rely on two components of a Linux OS: Cgroups to offer CPU/RAM/Network etc. resources and Namespaces to offer process and network isolation

There are two types of containers:

• System Containers (LXC, older technology)

• Application Containers (Docker, brings many improvements)

Containers vs. Virtualization

Containers are often and wrongly named a form of virtualization:

• More like partitioning or isolation

• Lack of a hypervisor

• Separation is done through other means

• Common is the kernel version between the host and the guest

• Logged in with a bash process on a container, it looks like a VM

• From the Host it looks like a group of processes

The benefits of using containers

Agility

Ship apps

faster

Portability

Easily move

workloads

Rapid scale

Scale easily

to meet

demand

Density

Achieve

resource

efficiency

Docker Container Advantages

• Possibility to create once and run it anywhere

• A portable runtime environment

• No “traditional ”issues of dependencies or packages

• Each application runs in an isolated container

• Small footprint of a container compared to a traditional VM

• Easy consistent and repeatable Application Environment

• Eliminate environment inconsistencies between development, test, production

Dockerfile

• Scripts creation of Docker images
