The CI failure is due to Docker Hub service unavailability (503 error), not related to the PR changes. The checks should pass once Docker Hub services are restored.

Also I noticed that the page uses the older docker-compose CLI. The newer one uses docker compose (without the hyphen).

@TheRootDaemon thanks for pointing out this issue of newer version.
My bad still on my system i uses older version.

Managor · 2025-10-21T10:39:57Z

Is the new version identical in its syntax?

TheRootDaemon · 2025-10-21T11:02:18Z

Is the new version identical in its syntax?

The hyphen is the only thing that changes. So no syntax changes.

TheRootDaemon

I am not sure what to use for a generic placeholder.
Whether to use {{N}} or {{line_count}} or just {{count}}.

But 100 won't generic, What do you think @anishk85 ?

TheRootDaemon · 2025-10-21T11:03:41Z

pages/common/docker-compose-logs.md

+
+- View only the last N lines of logs for each container:
+
+`docker compose logs {{[-n|--tail]}} {{100}}`


Suggested change

`docker compose logs {{[-n|--tail]}} {{100}}`

`docker compose logs {{[-n|--tail]}} {{line_count}}`

All are valid. Depends on what you want to do.
Do you want to describe the purpose of said number with words? Use {{line_number}}
Want to demonstrate with an example what the argument should look like? Use {{2474627}}
Want to keep it super simple with a one-letter variable? Use {{n}}

I initially used {{100}} as an example value to show a realistic usage(showing the last 100 lines), which is a common option in Docker and Unix commands (--tail 100, similar to tail -n 100).

Since I agree with you to use a generic placeholder it's better for new users.

As of now for new users I think we should use line_count only

I just want a generic placeholder like {{N}}.

We use lowercase {{n}} for consistency.

Have you tested that these commands work?
