this is what it looks like now :
# run with: docker-compose -f /etc/egroupware-collabora-key/docker-compose up -d
version: '2'
services:
collabora-key:
#image: "quay.io/egroupware/collabora-key:stable"
#image: "collabora/code:latest"
#volumes:
#- /var/lib/egroupware/default/loolwsd:/etc/loolwsd
# support for Collabora/CODE 21.11+
#- /var/lib/egroupware/default/loolwsd:/etc/coolwsd
# dont try to regenerate the (not used certificate) as volume is readonly
#environment:
#- DONT_GEN_SSL_CERT=1
#ports:
#- "127.0.0.1:9980:9980"
#restart: always
#container_name: collabora-key
# set the ip-address of your docker host AND your official DNS name so Collabora
# can access EGroupware without the need to go over your firewall
#extra_hosts:
#- "my.host.name:172.17.0.1"
logging:
options:
max-size: "1m"
max-file: "5"
[some watchtower settings below but the docker-compose.yml had it commented out anyway]
[i noticed why the error might ahve been… the file is really whitespace sensitive, i had not enough spaces in front of the options]
[ i also went to the egroupware-docker directory and amended the docker-compose.override and latest-docker-compose.override to the same effect - but the log file from collabora is still growing.]
result of docker-compose restart is success, but df -h still shows the file not deleted. although it has the log timestamp of the restart. the log ends with
