how can i have both http and https ?

How can i have both HTTP and HTTPS / force user using gitlab as HTTPS and can get rawdata of public projects as HTTP content ?

This is my gtlab with loadbalacner:

docker run --restart=always --name gitlab -d --link gitlab-postgresql:postgresql --link gitlab-redis:redisio --publish 10022:22 --publish 10081:80 \
  --env 'GITLAB_SSH_PORT=10022' --env 'GITLAB_HOST=git.example.com' --env 'GITLAB_PORT=10443' --env 'GITLAB_HTTPS=true' --env 'SSL_SELF_SIGNED=true' \
  --env 'GITLAB_SECRETS_DB_KEY_BASE=123123123' --env 'GITLAB_EMAIL_DISPLAY_NAME=Main Git Repository' \
  --env 'SMTP_USER=a11111@gmail.com' --env 'SMTP_PASS=1111' --env 'GITLAB_TIMEZONE=Europe/Berlin' \
  --env 'DB_NAME=gitlabhq_production' --env 'DB_USER=gitlab' --env 'GITLAB_ROOT_PASSWORD=123123123' \
  --env 'DB_PASS=234234234' \
  --volume $(pwd)/storage/data:/home/git/data sameersbn/gitlab:8.8.2
docker run --restart=always --name nginx-loadbalancer -d \
  --volume $(pwd)/config:/config \
  --publish 10443:443 --publish 10080:80 nginx-loadbalancer entrypoint

But during get data from raw content switch to https port. how can i solve this issue ?

Start with the two docker run commands and compare the GitLab HTTPS settings with the nginx-loadbalancer port mappings. Trace how raw public-project URLs are generated and whether they preserve the external HTTP or HTTPS scheme. Done means raw content uses the intended protocol while normal GitLab access remains HTTPS.
