Erase the rw & write the iso image via command line in linux

Howto: Linux write (burn) data to DVD or DVD/RW

In order to write DVD/DVD-RW from shell prompt you need to install a package called dvd+rw-tools.

DVD is another good option for backup, archiving, data exchange etc. You can install dvd+rw-tools with following commands. Also note that this package works under *BSD, HP-UX, Solaris and other UNIX like operating systems.

Debian installation:
# apt-get install 'dvd+rw-tools'

Fedora Core Linux installation:
# yum install 'dvd+rw-tools'

RedHat Enterprise Linux installation:
# up2date 'dvd+rw-tools'

In order to write DVD you need to install cdrecord tools.

How do I write DVD?

You need to use growisofs command, which combined mkisofs frontend/DVD recording program. From growisofs man page, "growisofs was originally designed as a frontend to mkisofs to facilitate appending of data to ISO9660 volumes residing on random-access media such as DVD+RW, DVD-RAM, plain files, hard disk partitions. In the course of development general purpose DVD recording support was implemented, and as of now growisofs supports not only random-access media, but even mastering of multiession DVD media such as DVD+R and DVD-R/-RW. In addition growisofs supports first-/single-session recording of arbitrary pre-mastered image (formatted as UDF, ISO9660 or any other file system, if formatted at all) to all supported DVD media types."

First create the ISO image
# mkisofs -r -o /tmp/var-www-disk1.iso /var/www

Now use the growisofs command to write the ISO onto the DVD:
# growisofs -Z /dev/dvd=/tmp/var-www-disk1.iso

To append more data for same DVD:
# growisofs -M /dev/dvd /tmp/file.1

To format (erase) a DVD:
# dvd+rw-format -force /dev/dvd
OR
# dvd+rw-format -force=full /dev/dvd

The dvd+rw-format command formats dvd disk in the specified dvd drive.

To display information about dvd drive and disk using dvd+rw-mediainfo command:
# dvd+rw-mediainfo /dev/dvd

Docker Container Management from Cockpit

Cockpit can manage containers via docker. This functionality is present in the Cockpit docker package. Cockpit communicates with docker via its API via the /var/run/docker.sock unix socket. The docker API is root equivalent, and on a properly configured system, only root can access the docker API. If the currently logged in user is not root then Cockpit will try to escalate the user’s privileges via Polkit or sudo before connecting to the socket. Alternatively, we can create a docker Unix group. Anyone in that docker group can then access the docker API, and gain root privileges on the system. [root@rhel8 ~] #  yum install cockpit-docker    -y  Once the package installed then "containers" section would be added in the dashboard and we can manage the containers and images from the console. We can search or pull an image from docker hub just by searching with the keyword like nginx centos.   Once the Image download...
