+# Central Server Docker Image
+
+***The Central Server images are strictly meant for testing and development purposes. Do not use it in production environment!***
+
+The Docker image (`niis/xroad-central-server`) is published on [Docker Hub](https://hub.docker.com/r/niis/xroad-central-server/).
+
+The Central Server Docker image contains vanilla X-Road Central Server.
+All services and PostgreSQL database, are installed into the same container and run using [supervisord](https://docs.docker.com/engine/containers/multi-service_container/#use-a-process-manager).
+
+TEST-CA, TSA, OCSP have a separate [Dockerfile](./../testca/Dockerfile).
+
+The installed Central Server is in uninitialized state.
+
+Admin UI credentials: `xrd`/`secret`
+
+## Building the Central Server image
+Run `init_context.sh` script that will collect the necessary files for building the image to `build` folder. After that you can create the image inside the newly created `build` folder.
+
+```shell
+cd Docker/centralserver/
+./init_context.sh
+cd build/
+docker build --build-arg DIST=jammy-current -t centralserver -f ../Dockerfile .
+```
+
+Alternatively, it's possible to use the image (`niis/xroad-central-server`) available on [Docker Hub](https://hub.docker.com/r/niis/xroad-central-server/).
+
+## Container parameters
+
+| Port   | Description                                                                      |
+|--------|----------------------------------------------------------------------------------|
+| `80`   | Ports for outbound connections (from the Central Server to the external network) | 
+| `2222` | Management REST API endpoint                                                     | 
+| `4000` | Main UI                                                                          |
+
+## Running
+
+Publish the container ports (`4000`, `80` and `9998`) to localhost (loopback address).
+
+Running a locally built image:
+```shell
+docker run -p 4000:4000 -p 4001:80 -p 4002:9998 --name cs centralserver
+```
+
+Running an image available on [Docker Hub](https://hub.docker.com/r/niis/xroad-central-server/):
+```shell
+docker run -p 4000:4000 -p 4001:80 -p 4002:9998 --name cs niis/xroad-central-server:bionic-7.1.0
+```
+
+## Running multiple dockerized X-Road (Security/Central) Servers
+If you are running multiple (more than one) containers and map container ports to localhost, it is recommended that you use a separate loopback address for each container and create a X-Road specific network so that containers can communicate.
+Accessing admin-ui of a server from the same domain will break session on other servers. You can get over this by setting multiple mappings to localhost in hosts-file.
+
+```shell
+# Create a custom network for x-road containers
+docker network create -d bridge x-road-network
+
+# Create more than one Central Server containers and (optionally) assign them a network-alias for easier reference
+docker run -p 4000:4000 -p 4001:80 -p 4002:9998 --network x-road-network --name cs1 niis/xroad-central-server
+docker run -p 4100:4000 -p 4101:80 -p 4102:9998 --network x-road-network --name cs2 niis/xroad-central-server
+```
+
+## Initializing vanilla Central Server
+After creating a vanilla Central Server, you need to create certificates. [Test CA](./../testca/README.md) could be used for Signing certificates.
+
+### Autologin
+The `xroad-autologin` add-on is installed, but there is no default PIN set, so the following error at startup is normal:
+```text
+... INFO exited: xroad-autologin (exit status 0; not expected)
+... INFO gave up: xroad-autologin entered FATAL state, too many start retries too quickly
+```
+One can create the autologin file by hand after initializing the Central Server:
+
+```shell
+$ docker exec cs su -c 'echo 1234 >/etc/xroad/autologin' xroad
+$ docker exec cs supervisorctl start xroad-autologin
+```
