# Docker standalone

First we need to create a Docker volume so we can make the configuration file, database and logs persistent.

```bash
docker volume create trulyp_data
```

Via this method it can be as easy as running the following command

```bash
docker run -it --pull always \
    -v trulyp_data:/app_data \
    -p 8899:8080 \
    --name trulyp \
    -e TRULYP_URL=http://localhost:8899 \
    ghcr.io/appsfortableau/trulyp:latest
```

> Don't forget to change the `TRULYP_URL` to a proper external domain. Current given domain is a example. Be sure it is a proper URL including schema (e.g. https\://), not just the hostname.

```bash
# --pull always will download latest image of `appsfortableau/trulyp:latest`
# -d to detatch command to back, run command in the background.
```

Change `latest` into one of the following to get more control over the version: e.g. `4` or `4.1` or full version `4.2.1`

{% hint style="info" %}
Check out our GitHub [package](https://github.com/orgs/appsfortableau/packages/container/package/writeback-extreme) to find the latest version.
{% endhint %}

Once the container is running, open the URL (e.g. above: `http://localhost:8899`) in your browser and click on "Go to the backend."

### After stopping the container

(Re)Start the container after closing the command can done via:

```bash
# start previous ran docker container:
docker start trulyp
```

{% hint style="info" %}
Note: the `docker start` command only works with named (via `--name` in the `docker run` command) containers, otherwise you have to look up the container ID with `docker containers` command.
{% endhint %}

#### Changing accessible port

By default port `8090` is exposed. In certain scenario's port `8090` is not available, the port can be change via the `docker run` command by adding `-p {port}:8090`. Where in port 8090 is the internal application port. Replace `{port}` with the desire port.

{% hint style="info" %}
Read more about port forwarding for Docker containers [here](https://docs.docker.com/reference/cli/docker/container/run/#publish).
{% endhint %}

### Update Trulyp container with a new version

If a new version is available, run the following commands to update:

<pre class="language-bash"><code class="lang-bash"><strong>docker pull ghcr.io/appsfortableau/trulyp:latest
</strong># or when having a targetted version to only fetch patches
docker pull ghcr.io/appsfortableau/trulyp:4.2
# Stop docker container from running
docker stop trulyp
# start docker container
docker start trulyp
</code></pre>

{% hint style="info" %}
All available image versions can be found [here](https://github.com/appsfortableau/writeback-extreme/pkgs/container/writeback-extreme).
{% endhint %}

### Other environment variables

| WBE\_NUM\_WORKERS | Normally, the number of workers is equal to the number of CPU's. Some environments cannot detect this properly. Then you need to set this manually. |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.infotopics.com/trulyp/getting-started/trulyp-installation/on-premises-installation/containerization/docker-standalone.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
