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
A reverse proxy publishes an application that already runs. The Nginx generator drafts a server block. It does not reload Nginx and it does not open a connection.
The backend is an address you administer. Do not proxy to a host you do not run, and do not point the proxy at a metadata address to see what happens. Do not disable TLS verification on the backend to silence an error.
One name, one backend. example.com is documentation. 192.0.2.10/24 and example.com are documentation. They stay in the note.
The change you can finish
Apply nothing while you are writing the note. When the lab window opens, it is one change on the host named in the ticket. Read the draft, then the host, then decide.
Rollback is the file, the package version, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.
- Name the public name and the backend.
- Confirm you run the backend.
- Draft the block.
- Reject a disabled TLS check.
- Do not reload during the reading.
- Stop.
Mistakes that outlive the command
Reverse Proxy Setup goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- A backend you do not run.
- TLS verification turned off.
- A metadata address used as a test.
- A reload during the reading.
- Two backends in one hour.
Decisions to write down
One decision for Reverse Proxy Setup: The backend is yours. TLS checks stay on. One name. No reload yet. And example.com is not the live name.
Checks before you call it done
Confirm this before you call the change done: The name is written. The backend is written. TLS verification was not disabled. No reload was done. And the host is yours. If one of those fails, stop.
# One backend you run.
# Do not disable TLS verification.
# Do not proxy to a host you do not administer.Before you leave the host
Reverse Proxy Setup ends when the hostname in the prompt matches the hostname in the ticket. If it does not, you are on the wrong host. Stop. A command that succeeded on the wrong host is not progress.
The draft stays a draft until a person has read the names in it. A generator does not log into the host and does not know which disk is empty. You delete a line that names a host, a path, or an account you did not write down.
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. They belong in the note. They are not values you leave on a host because a draft included them.
prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save in the ticket or in git. The real secret stays in the password store.
One change is the window. If two things move and the result is wrong, you will not know which one did it. The next change waits for its own page.
If the same step fails twice, stop for the day. The failure is the result. Adding a forum command beside a half-applied change produces a host nobody can rebuild. Restore the copy you took first.
A second person reads the hostname and the change aloud. If they cannot find them in the ticket, the note is not done. Silence is not agreement. Then leave the host alone.
This page is a planning guide. It is not a vendor manual, not an official standard, and not permission to touch a host you do not administer. You do not disable a firewall, AppArmor, or SELinux to make a check pass.
