-The arvados-ws server provides event notifications to websocket clients. It can be installed anywhere with access to Postgres database and the Arvados API server, typically behind a web proxy that provides SSL support.

-By convention, we use the following hostname for the websocket service.

-The above hostname should resolve from anywhere on the internet.
-
-h2. Install arvados-ws
-
-Typically arvados-ws runs on the same host as the API server.
-
-On Debian-based systems:
-
-
-~$ sudo apt-get install arvados-ws
-
-
+# "Update config.yml":#update-config
+# "Update nginx configuration":#update-nginx
+# "Install arvados-ws package":#install-packages
+# "Start the service":#start-service
+# "Restart the API server and controller":#restart-api
+# "Confirm working installation":#confirm-working
-On Red Hat-based systems:
-
-
-~$ sudo yum install arvados-ws
-
-
+h2(#configure). Update config.yml
-Verify that @arvados-ws@ is functional:
+Edit the cluster config at @config.yml@ and set @Services.Websocket.ExternalURL@ and @Services.Websocket.InternalURLs@. Replace @zzzzz@ with your cluster id.
-~$ arvados-ws -h
-Usage of arvados-ws:
- -config path
- path to config file (default "/etc/arvados/ws/ws.yml")
- -dump-config
- show current configuration and exit
-
+ Services:
+ Websocket:
+ InternalURLs:
+ "http://localhost:8005": {}
+ ExternalURL: wss://ws.ClusterID.example.com/websocket

-h3. Create a configuration file
-
-Create @/etc/arvados/ws/ws.yml@ using the following template. Replace @xxxxxxxx@ with the "password you generated during database setup":install-postgresql.html#api.

-h3. Set up a reverse proxy with SSL support
+h2(#update-nginx). Update Nginx configuration
The arvados-ws service will be accessible from anywhere on the internet, so we recommend using SSL for transport encryption.
-This is best achieved by putting a reverse proxy with SSL support in front of arvados-ws, running on port 443 and passing requests to arvados-ws on port 9003 (or whatever port you chose in your configuration file).
-
-For example, using Nginx:
+Use a text editor to create a new file @/etc/nginx/conf.d/arvados-ws.conf@ with the following configuration. Options that need attention are marked in red.
upstream arvados-ws {
- server 127.0.0.1:9003;
+ server 127.0.0.1:8005;
}
server {
- listen [your public IP address]:443 ssl;
- server_name ws.uuid_prefix.your.domain;
+ listen *:443 ssl;
+ server_name ws.ClusterID.example.com;
proxy_connect_timeout 90s;
proxy_read_timeout 300s;
ssl on;
- ssl_certificate YOUR/PATH/TO/cert.pem;
- ssl_certificate_key YOUR/PATH/TO/cert.key;
+ ssl_certificate /YOUR/PATH/TO/cert.pem;
+ ssl_certificate_key /YOUR/PATH/TO/cert.key;

-If you are upgrading a cluster where Nginx is configured to proxy @ws@ requests to puma, change the @server_name@ value in the old configuration block so it doesn't conflict. When the new configuration is working, delete the old Nginx configuration sections (i.e., the "upstream websockets" block, and the "server" block that references @http://websockets@), and disable/remove the runit or systemd files for the puma server.
