# NuLink Worker Update

The NuLink worker node need to be updated when a new version is released. The update in docker is simple: stop the node, pull the latest image and restart the node.

1. Stop the running node in Docker:

   ```shell
   docker kill <container ID>
   ```

   Delete the container:

   ```shell
   docker rm <container ID>
   ```
2. Pull the latest NuLink image.

   ```shell
   docker pull nulink/nulink:latest
   ```
3. Re-launch the worker node.

   ```shell
   docker run --restart on-failure -d \
   --name ursula \
   -p 9151:9151 \
   -v /root/nulink:/code \
   -v /root/nulink:/home/circleci/.local/share/nulink \
   -e NULINK_KEYSTORE_PASSWORD \
   -e NULINK_OPERATOR_ETH_PASSWORD \
   nulink/nulink nulink ursula run --no-block-until-ready
   ```
