Docker is an open platform for developing, shipping, and running applications. This image is packaged based on the latest version of CentOS Stream 9 in UEFI mode, while the root volume is lvm partitioned.
Docker allows you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications.
By taking advantage of Docker's methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production.
FAQ
1. Unable to connect via SSH
Please make sure that the security group has released port 22 and the network is connected. The key (if you are using MAC or Linux system, you need to make sure that the key permission is set to 600), username are correct, and also upgrade the version of SSH connection tool (because of the algorithm update, the earlier software version may not be able to support).
2. How to extend the partition size
Under normal circumstances, images with standard partitions will automatically expand the root volume size, while images with LVM partitions need to do it manually. Assuming you want to extend the root volume of an LVM partition, the steps are as follows:
a. Retrieve the disk information
# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
nvme0n1 259:0 0 12G 0 disk
L nvme0n1p1 259:1 0 100M 0 part /boot/efi
L nvme0n1p2 259:2 0 1G 0 part /boot
L nvme0n1p3 259:3 0 6.9G 0 part
L cs-root 253:0 0 6.9G 0 lvm /
b.Expand the physical partition
# partprobe /dev/nvme0n1
# growpart /dev/nvme0n1 3
c. Expand logical volume
# lvextend -l +100%FREE /dev/mapper/cs-root
d. Expand the file system
# xfs_growfs /
