josegonzalez opened a new issue #206:
URL: https://github.com/apache/couchdb-docker/issues/206
## Expected Behavior
I expect to be able to set a username via the `COUCHDB_USER` environment
variable with a length of 1 character.
## Current Behavior
Previous versions of the docker image did not have any validation on service
start. The current versions fails if the specified `COUCHDB_USER` is a single
character.
You'll see the following message on container start with a single-character
username:
```
*************************************************************
ERROR: CouchDB 3.0+ will no longer run in "Admin Party"
mode. You *MUST* specify an admin user and
password, either via your own .ini file mapped
into the container at /opt/couchdb/etc/local.ini
or inside /opt/couchdb/etc/local.d, or with
"-e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password"
to set it via "docker run".
*************************************************************
```
I believe the cause is the `\w+` in the regex check
[here](https://github.com/apache/couchdb-docker/blob/main/3.1.1/docker-entrypoint.sh#L85)
## Possible Solution
I think changing the `\w+` to `\w*` will allow the previous behavior.
## Steps to Reproduce (for bugs)
```shell
docker run -e COUCHDB_USER=l -e COUCHDB_PASSWORD=password -d couchdb
```
Here is an example of downstream usage of the image where it just constantly
restarts the container (though the error message isn't surfaced as I don't
surface that in the tests):

## Context
This breaks my tests, which I try to sync between all datastore plugins.
Fixing it just means increasing the username length, but its annoying since now
I can't easily copy the files over as tests change.
That said, its not a super-critical bug, just an annoying one.
