# Build without internet connection

Use this workflow if the production host has no Internet access.

Build (or pull) the Docker image on a machine with Internet access. Then transfer it to the isolated host.

### What you need

* Docker installed on the build machine and the production host.
* An image already built locally.

### Save the image to a tar archive

```bash
docker save -o wsc_app.tar local/wsc_app
```

### Transfer the tar file to the production host

Use `scp` (or `rsync`) over SSH:

```bash
scp wsc_app.tar REMOTE_USER@xx.xx.xx.xx:/path/on/remote
```

### Load the image on the production host

```bash
docker load -i /path/on/remote/wsc_app.tar
```

### Run the container on the production host

Use `--env` flags.

This avoids rebuilding images for environment-specific values.

Runtime values also override values baked into the image during `docker build`.

{% tabs %}
{% tab title="WPR\_VIRTUAL\_DIR=wscservice" %}

```bash
docker run -d \
  -p 80:8080 \
  --env WPR_PROTOCOL=2 \
  --env WPR_WEB_PORT=80 \
  --env WPR_VIRTUAL_DIR=wscservice \
  local/wsc_app
```

{% endtab %}

{% tab title="WPR\_VIRTUAL\_DIR=/" %}

```bash
docker run -d \
  -p 80:8080 \
  --env WPR_PROTOCOL=2 \
  --env WPR_WEB_PORT=80 \
  --env WPR_VIRTUAL_DIR=/ \
  local/wsc_app
```

{% endtab %}
{% endtabs %}

The two common endpoints are:

{% tabs %}
{% tab title="WPR\_VIRTUAL\_DIR=wscservice" %}

* Version: `http(s)://<host>/wscservice/api?cmd=ver`
* Status: `http(s)://<host>/wscservice/api?cmd=status`
  {% endtab %}

{% tab title="WPR\_VIRTUAL\_DIR=/" %}

* Version: `http(s)://<host>/api?cmd=ver`
* Status: `http(s)://<host>/api?cmd=status`
  {% endtab %}
  {% endtabs %}
