Normally, logrotate is run as a daily cron job. It will not modify a log
multiple times in one day unless the criterion for that log is based on
the log's size and logrotate is being run multiple times each day, or
unless the -f or --force option is used.
This cleans up tmp and logrotates /var/log every 12 hours.
Note that this janitor is separate from the box janitor because they
run as different users.
Fixes#503
There is a crash when:
* App is configured. So, oldConfig now has {loc, access, portb }
* Cloudron is restored. The restore code path accesses the oldConfig.manifest.addons.
oldConfig is basically a messaging passing thing. It's not really a
db field. With that spirit, we simply pass an empty message in setup_infra.sh
Docker generates an apparmor profile on the fly under /etc/apparmor.d/docker.
This profile gets overwritten on every docker daemon start.
This profile allows processes to ptrace themselves. This is required by
circus (python process manager) for reasons unknown to me. It floods the logs
with
audit[7623]: <audit-1400> apparmor="DENIED" operation="ptrace" profile="docker-default" pid=7623 comm="python3.4" requested_mask="trace" denied_mask="trace" peer="docker-default"
This is easily tested using:
docker run -it cloudron/base:0.3.3 /bin/bash
a) now do ps
b) journalctl should show error log as above
docker run --security-opt=apparmor:docker-cloudron-app -it cloudron/base:0.3.3 /bin/bash
a) now do ps
b) no error!
Note that despite this, the process may not have ability to ptrace since it does not
have CAP_PTRACE. Also, security-opt is the profile name (inside the apparmor config file)
and not the filename.

This is an infra update because we need to recreate containers to get the right profile.
Fixes#492
