This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.
What this hour is for
Sizing Kubernetes Nodes writes the cluster, the current size, and the candidate. Requests in the note are samples until you replace them. You do not scale a production pool, and you do not kubectl apply.
Write the account, project, or repository you administer, the name of this change, and the time. A second change waits until this line has been read back.
The browser tool drafts text or reads a paste you already hold. It does not log in, it does not scan, and it does not apply.
192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced.
The change you can finish
Apply nothing while you are writing the note. When the lab window opens, it is one change on the account named in the ticket. Read the draft, then the account, then decide.
Rollback is the previous file, the previous plan, or the lab resource you can delete because it was only a lab.
- Write the cluster you administer.
- Write the current size.
- Write one candidate.
- Do not scale.
- Stop.
Mistakes that outlive the statement
Sizing Kubernetes Nodes goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- A pool scaled during the reading.
- A candidate applied as a manifest.
- A cluster you do not administer.
- No current size written.
Decisions to write down
One decision for Sizing Kubernetes Nodes: The cluster is yours. Nothing is scaled. Nothing is applied. The current size is written. And one pool is the window.
Checks before you call it done
Confirm this before you call the change done: The cluster is written. Nothing was scaled. The current size is in the note. Nothing was applied. And a second person can say the candidate. If one of those fails, stop.
# Node-size note. Do not scale during the reading.
Before you leave the account
Sizing Kubernetes Nodes ends when the account in the note is the account in the ticket. If it is not, stop.
The draft stays a draft until a person has read the names in it. A generator does not log in, does not apply, and does not scan.
192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced. It is not a password you keep. 10.0.0.0/16 is a sample prefix, not a network you publish unless you already use it.
prompt-for-this is a reminder that a secret is missing. It is not an access key, a token, or a password you save. An Azure secret draft may contain a sample password. Replace it. Do not file it.
One change is the window. If two things move and the result is wrong, you will not know which one did it.
If the same step fails twice, stop for the day. Restore the copy you took first.
A second person reads the account and the change aloud. If they cannot find them in the ticket, the note is not done.
This page is a planning guide. It is not a vendor manual, not an official standard, not legal advice, and not an audit opinion. You do not apply it against an account you do not administer.
