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
Blue/Green vs Canary vs Rolling Deployments names the service you administer and the shape you use today. You do not shift traffic. You do not delete the previous version until a later ticket says a person has a way back.
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 service you administer.
- Name the current shape.
- Mark the others as unread.
- Do not shift traffic.
- Stop.
Mistakes that outlive the statement
Blue/Green vs Canary vs Rolling Deployments goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- Traffic shifted during the reading.
- The previous version deleted with no way back.
- Two shapes started at once.
- A service you do not administer.
Decisions to write down
One decision for Blue/Green vs Canary vs Rolling Deployments: The service is yours. Nothing is shifted. A way back is written before any later cut. One shape is the window. And unread stays labelled.
Checks before you call it done
Confirm this before you call the change done: The service is written. Nothing was shifted. The current shape is named. The way back is a sentence or marked missing. And a second person can say the shape. If one of those fails, stop.
# Release-shape note. Do not shift traffic during the reading.
Before you leave the account
Blue/Green vs Canary vs Rolling Deployments 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.
