Thanks @genofire I think the issue with FreeBSD test has been fixed with https://github.com/CollaboraOnline/online/commit/b412d61ca862688c91ede459c80e98427002cac6 . Could you please rebase this PR?

@genofire I tried to reach the Collabora online on "http://chart-example.local:/" it leads me to default haproxy backend. am I doing anything wrong here...?

[genofire]

@lpranam i do not know, what do you mean - do you have your values.yml for me to understand?

PS: We use nginx, because we need multiple LBs / Ingress-Pods (and thats works with the constant hash / the annotation upstream-by-hash).

I believe you need a values.yaml like:

collabora:
  server_name: "your-collabora-comain"
  aliasgroups:
    - domain: "https://your-micro-cooloud-domain:443"
ingress:
  enabled: true
  annotations:
    haproxy.org/timeout-tunnel: "3600s"
    haproxy.org/backend-config-snippet: |
      mode http
      balance leastconn
      stick-table type string len 2048 size 1k store conn_cur
      http-request set-var(txn.wopisrcconns) url_param(WOPISrc),table_conn_cur()
      http-request track-sc1 url_param(WOPISrc)
      stick match url_param(WOPISrc) if { var(txn.wopisrcconns) -m int gt 0 }
      stick store-request url_param(WOPISrc)
  hosts:
    - host: "your-collabora-comain"
      paths:
        - path: /

[lpranam]

@genofire that sounds great. I'd be available throughout the week at whatever time is convenient for you. I have had a glance through the PR several times but couldn't review it thoroughly. Sorry for that.
