# FuLink Worker Update

The FuLink worker node need to be updated when a new version is released.The update procedure could be different for the docker environment and local environment.

**Make sure putting a small amount of native token(WSOL) to the worker account for sending one confirmation transaction.**

### Update in docker environment <a href="#update-in-docker-environment" id="update-in-docker-environment"></a>

Make sure you still hold your staking account and worker account. The update in docker is simple: stop the node, pull the latest image and restart the node.

1. Stop the running node in Docker:

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

   Delete the container:

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

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

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