Collabora is not available

[ScharfViktor]

Step:

• start ocis with wopi using https://github.com/owncloud/ocis/blob/master/deployments/examples/ocis_wopi/docker-compose.yml or https://github.com/owncloud/web/blob/master/docker-compose.yml
• check if collabora is working

Actual:

app-provider-collabora log:

The collabora discovery endpoint is not reachable from the ocis-appprovider-collabora docker container

~ $ curl --show-error --fail http://collabora/hosting/discovery -vk
* Host collabora:80 was resolved.
* IPv6: (none)
* IPv4: 172.26.0.5
*   Trying 172.26.0.5:80...
* connect to 172.26.0.5 port 80 from 172.26.0.7 port 49054 failed: Connection refused
* Failed to connect to collabora port 80 after 3 ms: Couldn't connect to server
* Closing connection
curl: (7) Failed to connect to collabora port 80 after 3 ms: Couldn't connect to server

But on the host machine is works well curl -vk https://collabora.owncloud.test/hosting/discovery

This is a race condition when the app provider can't talk to nats and can't restart properly.

In case the app provider cannot read the discovery endpoint the process will terminate and restart - see this log:

Unless I miss anything in the next startup cycle reading the discovery url is successful and everything should work as design - but it doesn't .... why?

Please keep open, the mentioned PR should be reverted, we cannot use user:0 in any ocis container.

I tried to play around with a wait-for-it container - but this did not yet work out ... https://github.com/owncloud/ocis/compare/feat/docker-wait-for?expand=1
