How to set up FreeIPA server running in Docker in DigitalOcean droplet

Question

I followed tutorial (https://www.digitalocean.com/community/tutorials/how-to-set-up-centralized-linux-authentication-with-freeipa-on-centos-7) and from FreeIPA repository (https://github.com/freeipa/freeipa-container) but I want to set up BIND name server handling my zone.

What I should do in control panel of DNS? I left only A and MX records.

But when I set up FreeIPA server, I get this.

Checking DNS domain odisharia.ru., please wait ...
DNS zone odisharia.ru. already exists in DNS and is handled by server(s): []
The ipa-server-install command failed. See /var/log/ipaserver-install.log for more information
Sending SIGTERM to remaining processes...
Sending SIGKILL to remaining processes...
All filesystems, swaps, loop devices, MD devices and DM devices detached.
Exiting container.

Also I don’t know should I changed my host’s /etc/host file and what should I do put to it?

Hi there,

To set up FreeIPA server running in Docker in DigitalOcean Droplet, you can follow these steps:

Create a new Droplet and select the “Docker” 1-Click App.
Once the droplet is created, SSH into it.
Pull the FreeIPA Docker image:

docker pull freeipa/freeipa-server

Create a new Docker network:

docker network create freeipa

Run the FreeIPA Docker container:

docksher run -d --network freeipa -p 8080:8080 -p 443:443 freeipa/freeipa-server

Configure the DNS for your domain. You can use a BIND name server or another DNS server.
Once the DNS is configured, you can create users and groups in FreeIPA.

To set up BIND name server handling your zone, you can follow these steps:

Create a new zone file for your domain. The zone file should contain the following records:

@ IN SOA ns1.example.com. admin.example.com. (
  2023091601 ; serial
  3600 ; refresh
  900 ; retry
  604800 ; expire
  86400 ; minimum
)

@ IN NS ns1.example.com.

ns1 IN A 192.168.1.1

Save the zone file and restart the BIND name server.
You should now be able to access FreeIPA using the domain name you specified.

To fix the error you are getting, you need to make sure that the DNS server you are using is configured to handle the odisharia.ru. zone. You can do this by adding the odisharia.ru. zone to the DNS server’s configuration file.

You should also make sure that the odisharia.ru. zone is pointed to the IP address of the FreeIPA server. You can do this by editing the /etc/hosts file on your host machine and adding the following line:
