Tips#
When use wc -> be careful the header, need total - 1#
Store temporary commands / note / result in a fixed location like /root/tmp#
Even in remote host; we use that fixed location to store our results then get back the result from it#
remote$ cat tmp
remote$ exit
remote$ exit
local$ ssh remote cat tmp
Do not use tmux#
hard to copy and paste and scroll
One question one yml#
Name with q<no>.yml like q10.yml is the yml of 10th question
Write all resources on same yml in same question#
Set .vimrc#
set sw=2 ts=2 et
set hidden
Use alias#
export do='--dry-run=client -o yaml'
export now='--sort-by="{.metadata.creationTimestamp}"'
Use variable in command#
n=namespace
nn=name
i=image
s=server
Then you will find that we can reuse many command history. like
Create po yml#
k run -n $n $nn --image $i $do
Get po#
k get po $nn -n $n
Test service account#
k auth can-i --as=system:serviceaccount:$n:$nn
When working on next question, start a new vim (kill the old session)#
Keep a single vim session in bash#
- back and fore from vim and bash many times is needed
- using multiple vim session are so confusing
- that also why working on single yaml per question is encouraged
Create (touch /opt/xxxxx/q11/answer) the answer file first#
- needed to submit anser to specfic file
- just touch the file -> open it with vim -> put it in background (c-z)
