+# iconserver-deploy
+
+A playbook to deploy and manage [iconserver](https://github.com/mat/besticon).
+
+Includes two roles:
+* docker
+* iconserver
+
+## Docker
+Supported operating systems:
+* CentOS Stream 9, RHEL 9 and clones
+* Ubuntu 24
+* Debian 12
+
+Earlier versions and other debian-based distributions may not be compatible.
+(Please check [docker documentation](https://docs.docker.com/engine/install/).)
+
+## Iconserver
+The service is deployed via docker-compose config. Two services are deployed:
+* [iconserver](https://hub.docker.com/r/matthiasluedtke/iconserver)
+* [nginx](https://hub.docker.com/_/nginx)
+
+The service is deployed to be available via https using a self-signed certificate.
+Nginx configuration template can be edited in the role.
+
+## Deployment
+
+The project deployment has been developed and tested with `ansible-core 2.17.4`.
+If you run an earlier version your mileage may vary, but it should be compatible.
+
+To deploy the configuration the target servers have to be able to reach docker
+repos and docker hub via internet.
+
+Ansible config and inventory files are included. Update `inventory.yml` to match
+your setup.
+
+After that deploying the service is as simple as running:
+```bash
+ansible-playbook deploy.yml
+```
+(Add necessary options, like `-u` or `-K` etc.)
