After installation, found to add more space.

• Use fdisk -l to see the extra hard disk. Interesting that original hard drive is /dev/sdb while the new hard drive is /dev/sda.
• Create partition cfdisk /dev/sda to create /dev/sda1.
• Format the new disk: mkfs.ext4 /dev/sda1.
• Mount it to /disk_k8s: mkdir /disk_k8s; mount -t ext4 /dev/sda1 /disk_k8s.
• Use blkid /dev/sda1 to get this disk's UUID and use it in /etc/fstab file.

Now install docker.

• Create /disk_k8s/lib/docker and /disk_k8s/lib/containerd and soft link to /var/lib/docker and /var/lib/containerd respectively.
• Just follow the docker doc to install docker
• The above approach may be too old? do not work, but stach overflow provided solution. We need to sudo systemctl start docker to start docker service, and sudo build . -t [image_name] to build image.

Now Kubernetes.

• Remove swap permanantly: comment out swap line in /etc/fstab and reboot. To check it: free -h to see swap is zero.
• Check MAC address unique: ifconfig -a.
• Check product_uuid unique: sudo cat /sys/class/dmi/id/product_uuid.
• Install container runtime.
under cri-dockerd release list The package only exists for Buster 10, Bullseye 11, while I have Bookworm 12. Should I downgrade?
• Download Bullseye one: https://github.com/Mirantis/cri-dockerd/releases/download/v0.3.3/cri-dockerd_0.3.3.3-0.debian-bullseye_amd64.deb
• Install: sudo dpkg -i ./cri-dockerd_0.3.3.3-0.debian-bullseye_amd64.deb
• Continue using this version to see issues later.

Install Debian Linux under Oracle VM virtual box 7.0, then need to do the following:

• Use net-inst with ssh server and basic packages without X installed.
• Install net-tools apt install net-tools such that we will have ifconfig to see VM IP address.
• Install sudo apt install sudo then set existing use to it: usermod -aG sudo [user].
• VBoxLinuxAddtion
  1. Install linux header: sudo apt install linux-headers-$(uname -r).
  2. Mount CDROM: mount /media/cdrom.
  3. Install Addition: sh VBoxLinuxAttions.run.
• FVWM, Conky, and Xrdp
  1. Install basic packages: sudo apt install fvwm conky xrdp.
  2. For sound through xrdp, download: wget http://mxrepo.com/mx/testrepo/pool/test/p/pulseaudio-module-xrdp/pulseaudio-module-xrdp_0.4-0mx19_amd64.deb and install sudo dpkg -i Downloads/pulseaudio-module-xrdp_0.4-0mx19_amd64.deb
  3. FVWM with conky autorun:
     Get FVWM configuration file from system: cp /usr/share/fvwm2/default-config/config ~/.fvwm.
     Edit ~/.fvwm/config file add: + I Exec exec conky.
     Get Conky configuration file from system: cp /usr/share/doc/conky-std/conky.conf ~/.conkyrc.
     Edit ~/.conkyrc file add IP address as example: ${color grey}Networking: ${color red} ${exec hostname -I} $color.
     Sample [.conkyrc](sample_conf/dotconkyrc)
• Chinese terminal and inputs:
  1. RXVT terminal: apt install rxvt-unicode.
  2. Create ~/.Xresources file add configuration for RXVT: URxvt*font: xft:Monospace:size=12. Use this configuration without log-off/login: xrdb -merge ~/.Xresources.
  3. Install Chinese fonts: apt install fonts-arphic-ukai fonts-arphic-uming fonts-wqy-zenhei.
  4. Install Chinese input method: apt install fcitx.
  5. Found the reason fcitx didn't work. Need extra package: apt install fcitx-pinyin. 现在可以了。
• MultiMedia:
  1. Install them: apt install chromium dolphin mpv gwenview.
  2. Dolphin without folder icon: sudo apt install oxygen-icon-theme.
• Editor:
  1. Install VIM and Emacs: apt install vim emacs.
  2. Download VS code and install it: dpkg -i Downloads/code-[version].deb
• Samba:
  1. Install driver: apt install cifc-utils.
  2. Create mounting points: mkdir /mnt/data as example.
  3. Edit /etc/fstab to add line like //wdmycloud/data /mnt/data cifs guest,uid=1000,gid=1000,file_mode=0660,dir_mode=0770,iocharset=utf8 0 0. Here uid and gid with default 1000 for the first user and group. The file_mode and dir_mode is setting for writable. The guest option is used if Samba allow guest access.
  4. With configuration under /etc/fstab we can mount manually by mount /mnt/data or un-mount it umount /mnt/data, respectively.
• Mini Conda:
  Since Anaconda requires 3GB space, we like to install miniconda instead.
  1. Download Mini Conda.
  2. Install it: sudo sh Downloads/Miniconda3-latest-Linux-x86_64.sh and configure to under /opt
  3. Initialize it: /opt/miniconda3/bin/conda init to set base environment under ~/.bashrc file. The next time when you start with bash, we will have this environment.
  4. Resource: Conda cheat sheet.
• Chinese Input in Emacs
  Since fcitx failed to be loaded (not know why), try Chinese input from Emacs.
  1. Switch to Chinese input: Alt + x set-input-method with value chinese-py.这样就可以了
  2. Switch back to normal input: Alt + x toggle-input-method in case Ctrl + \ does not work.切换
• Add new user using existing group.
  Command: sudo adduser --home /home/username --ingroup group-name username.
