# Updating Nodes

## Docker Installation

The following instructions assume your docker install followed [these](/tbtc-signer-nodes/tbtc-v2-node-setup/installation/docker-installation.md) installation instructions. 

{% tabs %}
{% tab title="Docker Install" %}
To update a tBTC node:

Pull the new image

```bash
docker pull keepnetwork/keep-client:latest
```

Restart the tBTC service

```bash
sudo systemctl restart tbtcv2
```

To free system resources, run

```bash
sudo docker container prune
```

```bash
sudo docker image prune
```

Examine logs to ensure the node started correctly. Find Docker instance identification; it'll be a random combination of words, e.g. `stinky_brownie`:

```bash
sudo docker ps
```

Use specific identification and substitute accordingly; specify a path and file name for the log file:

```bash
sudo docker logs stinky_brownie >& /path/to/output/file
```

Display the log file 

```bash
cat /path/to/output/file
```

Look for the following and take note of the version:

Alternatively, verify your client updated by visiting your status page:

```
http://111.222.333.444:9601/metrics
```

Compare the displayed version number to the version number you are expecting, i.e.:

```
client_info{version="vX.X.X-XX"}
```
