+# Docker Image Tags Documentation
+
+This document describes the tags generated by the `docker/metadata-action` in the GitHub Actions workflow for building Docker images.
+
+## Base Name
+
+The base name for the Docker images is derived from the repository:
+
+- `ghcr.io/yacy/yacy_search_server` (GitHub Container Registry)
+- `yacy/yacy_search_server` (Docker Hub)
+
+## Version Structure
+
+The tags are generated based on the following rules:
+
+### Default Tags
+
+- `latest`: Automatically assigned to the latest tagged release.
+
+### Semantic Versioning Tags
+
+For releases following semantic versioning (e.g., `1.2.3` or the `Release_1.2` format), the following tags are created:
+
+- `1.2.3`: Full version tag.
+- `1.2`: Major and minor version tag.
+- `1`: Major version tag.
+
+### Branch Tags
+
+- `<branch-name>`: For latest commit of branches (bleeding edge channel, e.g. `master`).
+
+### Pull Request Tags
+
+- `pr-<number>`: For latest commit of pull requests.
+
+## Image Variants
+
+The Docker images come in many flavors, each designed for a specific use case.
+
+### `yacy/yacy_search_server:<version>`
+
+This is the default image. If you are unsure about what your needs are, you probably want to use this one.
+
+### `yacy/yacy_search_server:<version>-alpine`
+
+This image is based on the popular Alpine Linux project. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
+
+## Examples
+
+- `ghcr.io/yacy/yacy_search_server:latest`
+- `ghcr.io/yacy/yacy_search_server:1.2.3`
+- `ghcr.io/yacy/yacy_search_server:1.2`
+- `ghcr.io/yacy/yacy_search_server:1`
+- `ghcr.io/yacy/yacy_search_server:master`
+- `ghcr.io/yacy/yacy_search_server:pr-42`
+- `ghcr.io/yacy/yacy_search_server:latest-alpine`
+- `ghcr.io/yacy/yacy_search_server:1.2.3-alpine`

+# Yacy Docker image from latest sources
+
+## Supported tags
+
+* `latest` (Latest stable release)
+* `latest-alpine` (Latest stable release based on Alpine Linux)
+* `<version>` (Lock on a specific/minor/major version, e.g., `1.2.3`, `1.2`, `1`)
+* `<version>-alpine` (e.g., `1.2.3-alpine`)
+* `<branch-name>` (e.g., `master` for the latest commit of branches)
+* `pr-<number>` (e.g., `pr-42` for pull requests)
+
+For a detailed explanation of supported tags, refer to [DockerImageTags.md](./DockerImageTags.md).
+
+## Getting built image from Docker Hub and GitHub Container Registry
+
+The repository URLs are:
+
+* Docker Hub: <https://hub.docker.com/r/yacy/yacy_search_server/>
+* GitHub Container Registry: `ghcr.io/yacy/yacy_search_server`
+
+Examples:
+
+* `docker pull yacy/yacy_search_server:latest`
+* `docker pull ghcr.io/yacy/yacy_search_server:latest`
+* `docker pull ghcr.io/yacy/yacy_search_server:latest-alpine`
+* `docker pull ghcr.io/yacy/yacy_search_server:1.2.3`
+* `docker pull ghcr.io/yacy/yacy_search_server:master`
+* `docker pull ghcr.io/yacy/yacy_search_server:pr-42`
+
+## Building image yourself
+
+Using files in 'yacy_search_server/docker/':
+
+```sh
+cd yacy_search_server/docker
+```
+
+Then according to the image type:
+
+* `yacy/yacy_search_server:latest`: This image is based on the latest stable official [Eclipse Temurin](https://hub.docker.com/_/eclipse-temurin) 21 release. It includes YaCy compiled from the latest git repository sources.
+* `yacy/yacy_search_server:latest-alpine`: This image is based on the latest stable [Eclipse Temurin](https://hub.docker.com/_/eclipse-temurin) 21 release with Alpine Linux as the base. It also includes YaCy compiled from the latest git repository sources.
+
+```sh
+docker build -t yacy/yacy_search_server:latest -f Dockerfile ../
+```
+
+## Usage
+
+### Run the Docker image directly
+
+You can run the YaCy Docker image directly using the following command:
+
+```sh
+docker run -d --name yacy -p 8090:8090 -p 8443:8443 -v yacy_data:/opt/yacy_search_server/DATA --log-opt max-size=200m --log-opt max-file=2 yacy/yacy_search_server:latest
+```
+
+### Using Docker Compose
+
+You can also use Docker Compose to run the YaCy container. Create a `docker-compose.yml` file with the following content:
+
+```yaml
+services:
+    yacy:
+        container_name: yacy
+        image: yacy/yacy_search_server:latest
+        restart: unless-stopped
+        ports:
+            - "8090:8090"
+            - "8443:8443"
+        volumes:
+            - yacy_data:/opt/yacy_search_server/DATA
+        logging:
+            options:
+                max-size: "200m"
+                max-file: "2"
+
+volumes:
+    yacy_data:
+```
+
+Then start the container with:
+
+```sh
+docker-compose up -d
+```
+
+YaCy web interface is then exposed at `http://[container_ip]:8090`  
+You can retrieve the container IP address with `docker inspect`.
+
+### Default admin account
+
+* login: admin
+* password: yacy
+
+You should modify this default password with page /ConfigAccounts_p.html when exposing publicly your YaCy container.
+
+### Handle persistent data volume
+
+As configured in the Dockerfile, by default YaCy data (in /opt/yacy_search_server/DATA) will persist after container stop or deletion, in a volume named "yacy_data".
+
+### HTTPS support
+
+This images are default configured with HTTPS enabled, and use a default certificate stored in defaults/freeworldKeystore. You should use your own certificate. In order to do it, you can proceed as follow.
+
+#### Self-signed certificate
+
+A self-signed certificate will provide encrypted communications with your YaCy server, but browsers will still complain about an invalid security certificate with the error "SEC_ERROR_UNKNOWN_ISSUER". If it is sufficient for you, you can permanently add an exception to your browser.
+
+This kind of certificate can be generated and added to your YaCy Docker container with the following:
+
+```sh
+keytool -keystore /var/lib/docker/volumes/[your_yacy_volume]/_data/SETTINGS/yacykeystore -genkey -keyalg RSA -alias yacycert
+```
+
+Then edit YaCy config file. For example, with the nano text editor:
+
+```sh
+nano /var/lib/docker/volumes/[your_yacy_volume]/_data/SETTINGS/yacy.conf
+```
+
+And configure the keyStoreXXXX properties accordingly:
+
+```sh
+keyStore=/opt/yacy_search_server/DATA/SETTINGS/yacykeystore
+keyStorePassword=yourpassword
+```
+
+#### Import an existing certificate
+
+Importing a certificate validated by a certification authority (CA) will ensure you have full HTTPS support with no security errors when accessing your YaCy peer. You can import an existing certificate in pkcs12 format.
+
+First copy it to the YaCy Docker container volume:
+
+```sh
+cp [yourStore].pkcs12 /var/lib/docker/volumes/[your_yacy_volume]/_data/SETTINGS/[yourStore].pkcs12
+```
+
+Then edit YaCy config file. For example, with the nano text editor:
+
+```sh
+nano /var/lib/docker/volumes/[your_yacy_volume]/_data/SETTINGS/yacy.conf
+```
+
+And configure the pkcs12XXX properties accordingly:
+
+```sh
+pkcs12ImportFile=/opt/yacy_search_server/DATA/SETTINGS/[yourStore].pkcs12
+pkcs12ImportPwd=yourpassword
+```
+
+### Next starts
+
+#### As attached process
+
+```sh
+docker start -a yacy
+```
+
+#### As background process
+
+```sh
+docker start yacy
+```
+
+### Shutdown
+
+* Use "Shutdown" button in administration web interface
+* OR run:
+
+```sh
+docker exec yacy /opt/yacy_search_server/stopYACY.sh
+```
+
+* OR run:
+
+```sh
+docker stop yacy
+```
+
+### Upgrade
+
+To upgrade your YaCy container, follow these steps:
+
+1. Pull the latest Docker image:
+
+    ```sh
+    docker pull yacy/yacy_search_server:latest
+    ```
+
+2. Stop and remove the old container:
+
+    ```sh
+    docker stop yacy
+    docker rm yacy
+    ```
+
+3. Run the new container using the same command as before:
+
+    ```sh
+    docker run -d --name yacy -p 8090:8090 -p 8443:8443 -v yacy_data:/opt/yacy_search_server/DATA --log-opt max-size=200m --log-opt max-file=2 yacy/yacy_search_server:latest
+    ```
+
+#### Update Docker Compose Images
+
+To update the images created with the Docker Compose file, you can use the following command:
+
+```sh
+docker-compose up -d --force-recreate --pull always
+```
+
+This command ensures that the latest images are pulled and the containers are recreated with the updated images.
