deployment within apache as reverse proxy

hey man, just a quick information, maybe it’s useful for someone else. I run an Apache https webserver as reverseproxy and had some difficulties with the connection upgrade to websockets - but now it’s running correct with the following config:

activate needed apache modules: a2enmod proxy proxy_http proxy_html proxy_wstunnel filter rewrite substitute

# webssh.conf
#
# https://mydomain.org/ssh 
# Config for WebSSH Portal
##

<Location /ssh >
	ProxyPass  http://127.0.0.1:8888
       	ProxyPassReverse http://127.0.0.1:8888

# for websocket stuff
	RewriteEngine On
	RewriteCond %{HTTP:Upgrade}  ^WebSocket$ [NC, OR]
        RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC, OR]
        RewriteRule .*  ws://localhost:8888/ws$1 [P,L]

# rewrite response html to fix paths
       	AddOutputFilterByType SUBSTITUTE text/html
       	Substitute "s|static/js/|/ssh/static/js/|i"
       	Substitute "s|static/css/|/ssh/static/css/|i"
       	Substitute "s|static/img/|/ssh/static/img/|i"
</Location>

Also i created a systemd service to ensure webssh is running vi /etc/systemd/system/webssh.service with following content:

[Unit]
Description=Python WebSSH 
After=syslog.target network.target
StartLimitBurst=5, StartLimitIntervalSec=10

[Service]
ExecStart=/path/to/webssh_env/bin/wssh --address=127.0.0.1 --origin=https://mydomain.org  --port=8888 --log-file-prefix=/var/log/webssh.log 
ExecReload=/bin/kill -HUP $MAINPID
Type=simple
PIDFile=/var/run/webssh.pid
Restart=on-failure
RestartSec=1

[Install]
WantedBy=multi-user.target

systemctl daemon-reload && systemctl enable webssh.service && systemctl start webssh.service

regards!

Yet another working example as a virtual host:

<IfModule mod_ssl.c>
<VirtualHost *:443>
        ServerName  <hostname>

        ProxyPass / http://<ip-address>:8888/
        ProxyPassReverse / http://<ip-address>:8888/

        RewriteEngine On
        RewriteCond %{HTTP:Upgrade} websocket [NC]
        RewriteCond %{HTTP:Connection} upgrade [NC]
        RewriteRule ^/?(.*) "ws://<ip-address>:8888/$1" [P,L]

        ErrorLog ${APACHE_LOG_DIR}/<hostname>.error.log
        CustomLog ${APACHE_LOG_DIR}/<hostname>.access.log combined

SSLCertificateFile /etc/letsencrypt/live/<hostname>/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/<hostname>/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
</IfModule>

If you get an error about Cross origin not being allowed, add ProxyPreserveHost On to your config.
