<pre><code>~$ <span class="userinput">keep-web -h</span>
Usage of keep-web:
- -allow-anonymous
- Serve public data to anonymous clients. Try the token supplied in the ARVADOS_API_TOKEN environment variable when none of the tokens provided in an HTTP request succeed in reading the desired collection. (default false)
- -attachment-only-host string
- Accept credentials, and add "Content-Disposition: attachment" response headers, for requests at this hostname:port. Prohibiting inline display makes it possible to serve untrusted and non-public content from a single origin, i.e., without wildcard DNS or TLS.
- -listen string
- Address to listen on: "host:port", or ":port" to listen on all interfaces. (default ":80")
- -trust-all-content
- Serve non-public content from a single origin. Dangerous: read docs before using!
+ -config file
+ Site configuration file (default may be overridden by setting an ARVADOS_CONFIG environment variable) (default "/etc/arvados/config.yml")
+ -dump-config
+ write current configuration to stdout and exit
+[...]
+ -version
+ print version information and exit.

-If you intend to use Keep-web to serve public data to anonymous clients, configure it with an anonymous token. You can use the same one you used when you set up your Keepproxy server, or use the following command on the <strong>API server</strong> to create another. {% include 'install_rails_command' %}

-The basic command to start Keep-web in the service run script is:

- -attachment-only-host=<span class="userinput">download.uuid_prefix.your.domain</span> \
- -allow-anonymous \
- 2>&1
-</code></pre>
-</notextile>
-
-Omit the @-allow-anonymous@ argument if you do not want to serve public data.
-
-Set @ARVADOS_API_HOST_INSECURE=1@ if your API server's TLS certificate is not signed by a recognized CA.
-
h3. Set up a reverse proxy with TLS support
The Keep-web service will be accessible from anywhere on the internet, so we recommend using TLS for transport encryption.
If neither of the above wildcard options is feasible, you have two choices:
# Serve web content at @collections.uuid_prefix.your.domain@, but only for unauthenticated requests (public data and collection sharing links). Authenticated requests will always result in file downloads, using the @download@ name. For example, the Workbench "preview" button and the "view entire log file" link will invoke file downloads instead of displaying content in the browser window.
-# In the special case where you know you are immune to XSS exploits, you can enable the "trust all content" mode in Keep-web (with the @-trust-all-content@ command line flag) and Workbench (with the @trust_all_content@ item in @application.yml@). With both of these enabled, inline web content can be served from a single @collections@ host name; no wildcard DNS or certificate is needed. Do not do this without understanding the security implications described in the "Keep-web documentation":http://godoc.org/github.com/curoverse/arvados/services/keep-web.

Workbench has features like "download file from collection" and "show image" which work better if the content is served by Keep-web rather than Workbench itself. We recommend using the two different hostnames ("download" and "collections" above) for file downloads and inline content respectively.
-Add the following entry to your Workbench configuration file (@/etc/arvados/workbench/application.yml@). This URL will be used for file downloads.
+The following entry on your cluster configuration file (@/etc/arvados/config.yml@) details the URL that will be used for file downloads.
