Great Session Sir g............. We have the option to install Docker on a Red Hat machine. Why did you choose to use an Ubuntu machine instead of RHEL?

Hello Sir !! Thanks for this enlightening and grateful session I forget to ask in session. There is also curl-based docker-script , mentioned in Docker website Is it also preferable way of Installation in Production Env ?? Thanks !!

@NehraClasses Ай бұрын

that is not the script, actually by running that command we made an entry in the file for enabling docker repository.

Cloning an entire operating system on a bare-metal production server is a critical task and must be handled carefully to avoid downtime or accidental data loss. It is possible to clone the OS without VMware, and there are several approaches you can use depending on your requirements and environment. Here's a guide: 1. Using dd Command The dd command can create a bit-by-bit copy of the disk. Steps: Boot into a live environment (USB or CD with Linux OS like AlmaLinux or CentOS). Identify the source disk and target disk using lsblk or fdisk -l. Example: /dev/sda (source), /dev/sdb (target). Clone the disk: dd if=/dev/sda of=/dev/sdb bs=64K conv=noerror,sync status=progress Verify the clone by mounting the target disk and ensuring data integrity. 2. Using Clonezilla Clonezilla is an open-source tool for disk imaging and cloning. Steps: Download the Clonezilla ISO and create a bootable USB. Boot your server into Clonezilla. Choose "Device-to-Device" cloning for a direct disk copy. Follow the on-screen instructions to clone your OS disk. 3. Using rsync If your goal is to replicate the file system without cloning the disk structure, rsync can be used. Steps: Boot into a live environment or use a backup server. Use the following command to copy all files: rsync -aAXv /* /path/to/backup --exclude={/dev,/proc,/sys,/tmp,/run,/mnt,/media,/lost+found} Reinstall the bootloader on the target disk: grub2-install /dev/sdb grub2-mkconfig -o /boot/grub2/grub.cfg 4. Using Logical Volume Snapshots If you are using LVM, you can create a snapshot and back it up. Steps: Create a snapshot of the logical volume: lvcreate --size 10G --snapshot --name root_snap /dev/VolGroup/root Mount the snapshot and back it up using tar or rsync. 5. Using fsarchiver fsarchiver is another tool to create a filesystem-level backup. Steps: Install fsarchiver on your live environment. Save the filesystem: fsarchiver savefs /path/to/backup/root.fsa /dev/sda1 Restore it on the target disk: fsarchiver restfs /path/to/backup/root.fsa id=0,dest=/dev/sdb1 Considerations for Production Servers Downtime: Cloning an active server may require downtime. Data Consistency: Use tools like LVM snapshots or create backups during low-usage hours. Storage Size: Ensure the target disk has equal or larger storage capacity. Testing: Clone and test the backup on a non-production server before applying it to production. Best Approach for Production Minimize Risk: Use a reliable cloning tool like Clonezilla or dd. Test the Clone: Restore and test the cloned OS on a different server or environment. Document the Process: Keep a detailed log of the commands and steps performed. Let me know if you need step-by-step guidance on any specific tool!
