Docker objects

Explanation:
When you use docker, you’re making and using pictures, containers, networks, volumes,
plugins, and alternative objects. This section could be a brief summary of some of those
objects.
IMAGESAn image is a read-only template with instructions for making a docker container.
Often, a picture relies on another image, with some further customization. for instance,
you’ll build a picture that relies on the ubuntu image, however installs the Apache internet
server and your application, still because the configuration details required to create your
application run.
You may produce your own pictures otherwise you might solely use those created by
others and printed in a registry. to create your own image, you produce a Dockerfile with a
simple syntax for defining the steps needed to make the image and run it. every instruction
in a Dockerfile creates a layer within the image. once you change the Dockerfile and
rebuild the image, solely those layers that have modified square measure remodeled. this
is often a part of what makes pictures therefore light-weight, small, and fast, when put next
to alternative virtualization technologies.
CONTAINERSA instrumentality could be a runnable instance of a picture. you’ll produce,
start, stop, move, or delete a instrumentality victimization the docker API or user interface.
you’ll connect a instrumentality to at least one or a lot of networks, attach storage to that, or
perhaps produce a brand new image supported its current state.
By default, a container is relatively well isolated from alternative containers and its host
machine. you’ll management however isolated a container’s network, storage, or
alternative underlying subsystems square measure from alternative containers or from the
host machine.
A instrumentality is outlined by its image still as any configuration choices you offer to that
once you produce or begin it. once a instrumentality is removed, any changes to its state
that aren’t hold on in persistent storage disappear.
Example docker run commandThe following command runs an ubuntu container, attaches
interactively to your native command-line session, and runs /bin/bash.
$ docker run -i -t ubuntu /bin/bash
When you run this command, the subsequent happens (assuming you’re victimization the
default written account configuration):
If you are doing not have the ubuntu image locally, docker pulls it from your
designed registry, like you had run docker pull ubuntu manually.
docker creates a new container, like you had run a docker container create
command manually.
docker allocates a read-write filesystem to the container, as its final layer. this
permits a running container to make or modify files and directories in its native
filesystem.
dock-walloper creates a network interface to attach the docker to the default
network, since you did not specify any networking choices. This includes assigning
an IP address to the instrumentality. By default, containers will connect with
external networks victimization the host machine’s network connection.
docker starts the container and executes /bin/bash. as a result of the container is
running interactively and connected to your terminal (due to the -i and -t flags),
you’ll offer input using your keyboard whereas the output is logged to your
terminal.
when you type exit to terminate the /bin/bash command, the container stops
however isn’t removed. you’ll begin it once more or take away it.
SERVICESServices permit you to scale containers across multiple docker daemons, that
all work along as a swarm with multiple managers and employees. every member of a
swarm could be a docker daemon, and every one the daemons communicate victimization
the docker API. A service permits you to outline the desired state, like the quantity of
replicas of the service that has to be offered at any given time. By default, the service is
load-balanced across all employee nodes. To the consumer, the docker API service seems
to be one application. docker Engine supports swarm mode in docker one.12 and better
