# Container Scanner

Similarly to the Dockerized Client, the [Container Scanner](/containers-support/container-scanner.md) needs to be manually configured to ensure the scan runs for you dedicated instance. Prior to invocation ensure you set the following environment variables as such

<table><thead><tr><th width="225">Name</th><th>Description</th></tr></thead><tbody><tr><td>METERIAN_ENV</td><td>Set this variable to target the right subdomain of the site where your instance runs</td></tr><tr><td>METERIAN_PROTO</td><td>Set this variable to target the right HTTP protocol of the site where your instance runs</td></tr><tr><td>METERIAN_DOMAIN</td><td>Set this variable to target the right domain of the site where your instance runs</td></tr></tbody></table>

You can check that your client is correctly connecting to the dedicated instance executing the client with "--help", which will display the instance and the account it is connecting to.

```
$ export METERIAN_ENV=acme
$ export METERIAN_DOMAIN=meterian.uk
$ docker-scan --help
