What this hour is for
How to Self-Host n8n with Docker Compose drafts a Compose file for a lab n8n. Replace the sample password. Do not publish the admin port to the internet. Do not mount the Docker socket into the container.
The volume is a copy, not the only copy of the data. You do not run compose up during the reading.
The browser tool drafts text. It does not start the stack.
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.
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 account, project, or repository, and confirm you administer it.
- Save the current file or export before any draft is applied.
- Read the draft and delete every line this ticket did not name.
- Replace account IDs, images, example.com, and any sample password.
- Apply nothing during the reading.
- Read the names back and compare them with the ticket.
- Stop. The next change is a different page.
Mistakes that outlive the statement
n8n compose goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- Applying a draft you did not read.
- The wrong account.
- A secret, an access key, or a kubeconfig in git.
- Two changes in one window.
- No copy saved before the change.
- A documentation address or example.com left in a file you apply.
- An ingress from 0.0.0.0/0 left in the file.
- Calling the generator output a finished production change.
- The admin port published to every address.
- The Docker socket mounted into the container.
- compose up during the reading.
- The only copy of the data used as the volume.
Decisions to write down
One decision for n8n compose: The host is a lab host you administer. The stack is only n8n. The sample password was replaced. The admin port is not published to every address. And nothing was started during the reading.
Checks before you call it done
Confirm this before you call the change done: The host is written. The file was read. No sample password remains. The Docker socket is not mounted. Nothing was started. And a copy of the data exists before any later start. If one of those fails, stop.
# Compose lab for n8n.
# Replace the sample password. Do not publish the admin port.
# Do not mount the Docker socket. Do not run compose up during the reading.
# 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.Before you leave the account
How to Self-Host n8n with Docker Compose 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.
