-# Quick Guide
- Required: Domain, Email
-  - SSL and IDP configuration requires certificates. (If you already have certificates in use, substitute them into the nginx configuration values of the iam manager)
-
-1. Certificate Issuance (docker execution)
- Execution location: ./conf/docker
-```shell 
-sudo docker compose -f docker-compose.cert.yaml up
-```
-When issuance is successful, pem files are created in the folder with the corresponding domain name.
-ex)
- ./container-volume/mc-iam-manager/certs/live/<my domain>fullchain.pem
- ./container-volume/mc-iam-manager/certs/live/<my domain>/privkey.pem
-
-After domain issuance is complete, run docker down (to be used again for future renewals)
-```shell 
-sudo docker compose -f docker-compose.cert.yaml up
-```

-2. Execute nginx configuration script
- (If the owner of container-volume is root, change ownership to the appropriate user)
-```shell 
-  sudo chown -R ubuntu:ubuntu ./container-volume
-  cd mc-iam-manager
-  ./0_preset_create_nginx_conf.sh

- Creates files in container-volume/mc-iam-manager/nginx using template files and configuration information under the mc-iam-manager folder.
