Install Docker and pull image to local repository – Part 1


Docker, is an open-source lightweight virtualization tool designed to make it easier to create, deploy, and run applications by using containers.
Docker is a bit like a virtual machine. But it will not creating a whole virtual operating system, Docker allows applications to use the same Linux kernel as the system that they’re running on and only requires applications

In this section we will see how to install docker in CentOS-6.8 x86_64

Step 1: Install Prerequisites and docker package

[root@docker ~]# yum install epel-release

[root@docker ~]# yum install docker-io

Dependencies Resolved

================================================================================
Package Arch Version Repository
Size
================================================================================
Installing:
docker-io x86_64 1.7.1-2.el6 epel 4.6 M
Installing for dependencies:
bridge-utils x86_64 1.2-10.el6 base 30 k
libcgroup x86_64 0.40.rc1-23.el6 base 131 k

Transaction Summary
================================================================================
Install 10 Package(s)

Total download size: 5.6 M
Installed size: 22 M
Is this ok [y/N]: y

Installed:
docker-io.x86_64 0:1.7.1-2.el6

Dependency Installed:
bridge-utils.x86_64 0:1.2-10.el6
libcgroup.x86_64 0:0.40.rc1-23.el6
lua-alt-getopt.noarch 0:0.7.0-1.el6

xz.x86_64 0:4.999.9-0.5.beta.20091007git.el6

Complete!

Step 2: Start the docker service

[root@docker ~]# /etc/init.d/docker status
docker is stopped
[root@docker ~]# /etc/init.d/docker start
Starting cgconfig service: [ OK ]
Starting docker: [ OK ]
[root@docker ~]# chkconfig docker on

Step 3: Docker Check

Execute below command to see the version of installed docker application

[root@docker ~]# docker version
Client version: 1.7.1
Client API version: 1.19
Go version (client): go1.4.2
Git commit (client): 786b29d/1.7.1
OS/Arch (client): linux/amd64
Server version: 1.7.1
Server API version: 1.19
Go version (server): go1.4.2
Git commit (server): 786b29d/1.7.1
OS/Arch (server): linux/amd64

To see the basic information about the docker

[root@docker ~]# docker info
Containers: 0
Images: 0
Storage Driver: devicemapper
Pool Name: docker-253:0-5084-pool
Pool Blocksize: 65.54 kB
Backing Filesystem: extfs
Data file: /dev/loop0
Metadata file: /dev/loop1
Data Space Used: 305.7 MB
Data Space Total: 107.4 GB
Data Space Available: 7.027 GB
Metadata Space Used: 729.1 kB
Metadata Space Total: 2.147 GB
Metadata Space Available: 2.147 GB
Udev Sync Supported: true
Deferred Removal Enabled: false
Data loop file: /var/lib/docker/devicemapper/devicemapper/data
Metadata loop file: /var/lib/docker/devicemapper/devicemapper/metadata
Library Version: 1.02.117-RHEL6 (2016-04-01)
Execution Driver: native-0.2
Logging Driver: json-file
Kernel Version: 2.6.32-642.el6.x86_64
Operating System:
CPUs: 1
Total Memory: 1.826 GiB
Name: docker.devtcs.local
ID: DW2Z:OXCT:IJIK:X7DQ:5X4E:KNZN:RYQ6:GMGG:GRGS:M426:DEMZ:QKEE

Step 4: Search and Pull the docker registry for latest CentOS images

[root@docker ~]# docker search centos

where,

Name – Name of the Docker Image
STARS – Indicates the popularity of the Image. It’s good to go with the most STARS

Below command only pulls the docker image to your local repository and does not run it.

[root@docker ~]# docker pull centos
latest: Pulling from centos

d9cdac769794: Pull complete
8b7794bcb4f9: Pull complete
f3b88ddaed16: Pull complete
Digest: sha256:acb3b91e930743331be14cd3c8154da9967e2a2fca2aad0e1f27efce6deb2884
Status: Downloaded newer image for centos:latest

Check your local image repository by running the below command.

[root@docker ~]# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
centos latest f3b88ddaed16 4 weeks ago 192.5 MB

To check the status of your images

Install Openfiler as a Guest OS in VirtualBox


In my previous post we have seen the steps to install VirtualBox on CentOS. Here we are going to see the steps to install Openfiler as a guest os on VirtualBox.

After installing VirtualBox follow the steps below.

The term “Guest OS” refers to the operating system which is to be installed inside a VirtualBox.

Step1: Create a Virtual Machine

First job is to create a virtual machine, to do open VirtualBox and click “New” from the toolbar.

Select “New” from the toolbar to create a new Virtual Machine

Enter any name for your Virtual Machine and select the Operating System you are going to use as your GUEST OS. ie., Enter Openfiler in Name field

Select the OS you are going to use inside your Virtual Machine. ie., Select the type as Linux and Version is Linux 2.6 (64 bit)

Select the amount of RAM to be allocated to the Virtual Machine. ie., Minimum RAM should be 512MB

You need to create a Virtual Hard disk for your Virtual Machine. ie., Minimum 10GB Dynamic Partition

Step 2: Change the boot order of the VM

Right click the newly created Virtual machine and go to settings.

Go to the settings of your Virtual Machine

Select storage from the left side list, select the CD icon and from the right select “Choose a virtual CD/DVD disk file”, navigate to the Openfiler ISO image file of the OS on your computer. Now the OS image is mounted to your Virtual machine.

To change the boot device order of your virtual machine go to the “System” option from the left side list, select Hard Disk and click the up arrow to bring it to the top of the list. Make the CD/DVD-ROM the second device and uncheck the other devices.

Set the boot device priority for the virtual machine.

Step 3: Start the Virtual machine

To start the virtual machine double-click the VM, a window opens here you can press F12 if you want to select a device of your choice to boot.

Press F12 to select the boot device of your choice

To boot from the CD-ROM press c.

Press c to boot the VM from a CD image

Your VM will now boot from your Operating System image file and the OS installation will start as usual.

Step 4: Openfiler Installation

Use the below link to install and configure openfiler guest os.

Install Oracle VirtualBox on CentOS/RedHat 6/5


Oracle VirtualBox is a cross-platform virtualization application(windows/linux). It extends the capabilities of your existing operating system so that it can run multiple operating systems at the same time.

Here we are going to see how to install VirtualBox on CentOS/RHEL using repoistory.

Step 1: Required yum repositories

First we need to create VirtualBox yum repository on linux server.

[root@server.local ~]#cd /etc/yum.repos.d/
[root@server.local ~]#wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

Download and install CentOS/RHEL EPEL repository

CentOS/RHEL 6, 32 Bit (i386):
[root@server.local ~]#rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

CentOS/RHEL 6, 64 Bit x86_64):
[root@server.local ~]#rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

CentOS/RHEL 5, 32 Bit (i386):
[root@server.local ~]#rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

CentOS/RHEL 5, 64 Bit (x86_64):
[root@server.local ~]#rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

Step 2: Install dependency packages

Oracle VirtualBox requried some dependency packages to run virtualbox.

[root@server.local ~]#yum install gcc make patch dkms qt libgomp
[root@server.local ~]#yum install kernel-headers kernel-devel fontforge binutils glibc-headers glibc-devel

Step 3: Environment variable configuration

VirtualBox installation required kernel source code to install required modues, so we need to configure environment variable KERN_DIR.

[root@server.local ~]#KERN_DIR=/usr/src/kernels/2.6.32-220.2.1.el6.i686
[root@server.local ~]#export KERN_DIR

Step 4: Install VirtualBox

The below command is used to install Oracle VirtualBox

[root@server.local ~]#yum install VirtualBox-4.3

Finally re-run vboxdrv setup. This step may take a while to complete:

[root@server.local ~]#/etc/init.d/vboxdrv setup

Step 5: Start VirtualBox

Use following command to start VirtualBox from X windows. You can switch to GUI mode using init 5 or startx commands from terminal.

[root@server.local ~]# virtualbox &
