cockpit-ws - Cockpit web service


cockpit-ws [--help] [--port PORT] [--no-tls] [--local-ssh] [--address ADDRESS]


The cockpit-ws program is the web service component used for communication between the browser application and various configuration tools and services like cockpit-bridge(8). Users or administrators should never need to start this program as it automatically started by systemd(1) on bootup.


To specify the TLS certificate the web service should use, simply drop a file with the extension .cert in the /etc/cockpit/ws-certs.d directory. If there are multiple files in this directory, then the highest priority one is chosen after sorting. The .cert file should contain at least two OpenSSL style PEM blocks. First one or more BEGIN CERTIFICATE blocks for the server certificate and intermediate certificate authorities and a last one containing a BEGIN PRIVATE KEY or similar. The key may not be encrypted. If there is no TLS certificate, a self-signed certificate is automatically generated using openssl and stored in the 0-self-signed.cert file. To check which certificate cockpit-ws will use run the following command. $ sudo remotectl certificate If using certmonger to manage certificates, following command can be used to automatically prepare concatenated .cert file: CERT_FILE=/etc/pki/tls/certs/$(hostname).pem KEY_FILE=/etc/pki/tls/private/$(hostname).key getcert request -f ${CERT_FILE} -k ${KEY_FILE} -D $(hostname --fqdn) -C "sed -n w/etc/coc ↲ kpit/ws-certs.d/50-from-certmonger.cert ${CERT_FILE} ${KEY_FILE}"


When started via systemd(1) then cockpit-ws will exit after 90 seconds if nobody logs in, or after the last user is disconnected.


--help Show help options. --local-ssh Normally cockpit-ws uses cockpit-session and PAM to authenticate the user and start a user session. With this option enabled, it will instead authenticate via SSH at port 22. --port PORT Serve HTTP requests PORT instead of port 9090. Usually Cockpit is started on demand by systemd socket activation, and this option has no effect. Update the ListenStream directive cockpit.socket file in the usual systemd manner. --address ADDRESS Bind to address ADDRESS instead of binding to all available addresses. Usually Cockpit is started on demand by systemd socket activation, and this option has no effect. In that case, update the ListenStream directive in the cockpit.socket file in the usual systemd manner. --no-tls Don't use TLS.


The cockpit-ws process will use the XDG_CONFIG_DIRS environment variable from the XDG basedir spec[1] to find its cockpit.conf(5) configuration file. In addition the XDG_DATA_DIRS environment variable from the XDG basedir spec[1] can be used to override the location to serve static files from. These are the files that are served to a non-logged in user.
