Upgrading the Wazuh Docker deployment

To upgrade your Wazuh deployment using Docker, update the image tags in the docker-compose.yml file to the target version (5.0.0) and redeploy the stack.

Follow these steps to upgrade your deployment using the default docker-compose.yml file:

Stop the current deployment

Stop and remove the running containers:
```
# docker compose down
```

Update the image tags

Edit the image tags of all the services in the docker-compose.yml file to your desired version tag:

Single-node deployment

Navigate to the wazuh-docker/single-node/ directory:
```
# cd wazuh-docker/single-node/
```

Edit the docker-compose.yml file and update the image field for all Wazuh services to the desired version.

services:
  wazuh.manager:
    image: wazuh/wazuh-manager:5.0.0-beta2-latest
    ...
  wazuh.indexer:
    image: wazuh/wazuh-indexer:5.0.0-beta2-latest
    ...
  wazuh.dashboard:
    image: wazuh/wazuh-dashboard:5.0.0-beta2-latest
    ...

Multi-node deployment

Navigate to the wazuh-docker/multi-node/ directory:
```
# cd wazuh-docker/multi-node/
```

Edit the docker-compose.yml file and update the image field for all Wazuh services to the desired version.

services:
  wazuh.master:
    image: wazuh/wazuh-manager:5.0.0-beta2-latest
    ...
  wazuh.worker:
    image: wazuh/wazuh-manager:5.0.0-beta2-latest
    ...
  wazuh1.indexer:
    image: wazuh/wazuh-indexer:5.0.0-beta2-latest
    ...
  wazuh2.indexer:
    image: wazuh/wazuh-indexer:5.0.0-beta2-latest
    ...
  wazuh3.indexer:
    image: wazuh/wazuh-indexer:5.0.0-beta2-latest
    ...
  wazuh.dashboard:
    image: wazuh/wazuh-dashboard:5.0.0-beta2-latest
    ...

Start the updated deployment

Start the upgraded Wazuh Docker environment using the docker compose command:
```
# docker compose up -d
```

Your data and certificates remain persistent because they are stored in mounted Docker volumes. This means upgrading the environment does not erase your existing configuration or indexed data.
