Error at container startup sed: couldn't open temporary file /home/git/gitlab/config...

When I start this container I have an error that disappear at restart

gitlab_1_dabd7146875a | sed: couldn't open temporary file /home/git/gitlab/config/sednyAaZK: Permission denied

Can you give me some advice on how to fix it ?

I read its becouse i not have
USERMAP_UID AND USERMAP_GID
but after change this from default 1000 to 1010 i have not URL to go and not work all time.

This is my config yml:

gitlab:
  environment:
    DEBUG: 'false'
    GITLAB_PORT: 10083
    GITLAB_SECRETS_DB_KEY_BASE: qcs-gitlab-app
    GITLAB_SECRETS_OTP_KEY_BASE: qcs-gitlab-app
    GITLAB_SECRETS_SECRET_KEY_BASE: qcs-gitlab-app
    GITLAB_SSH_PORT: 10022

  - redis:redisio
  - postgresql:postgresql
  ports:

  - '10022:22'
  restart: always
postgresql:
  environment:
    DB_EXTENSION: pg_trgm
    DB_NAME: gitlabhq_production
    DB_PASS: password
    DB_USER: gitlab

redis:

  restart: always

Start with the container startup log and the supplied config.yml, focusing on the /home/git/gitlab/config path and the USERMAP_UID and USERMAP_GID settings. Reproduce the startup sequence and determine why sed cannot create its temporary file; done means the container starts reliably without the permission error and remains reachable at the configured URL.
