the latest superchanged changed the meaning of 'error'. Previously,
error implied a network error. With the latest superagent, error means
a REST api error i.e 4xx, 5xx are flagged as errors.
error && !error.response means network error
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
We explicitly mark /tmp, /run and /var/log as writable volumes.
Docker creates such volumes in it's own volumes directory. Note
that these volumes are separate from host binds (/app/data).
When removing the container the docker created volumes are
removed (but not host binds).
Fixes#196
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.
