--------------------------------------
Summary: Can't mount /dev/log
Key: MESOS-7223
URL: https://issues.apache.org/jira/browse/MESOS-7223
Project: Mesos
Issue Type: Bug
Components: containerization
Affects Versions: 1.1.0
Reporter: Haralds Ulmanis
I'm trying to mount /dev/log.
ls -l /dev/log
lrwxrwxrwx 1 root root 28 Mar 9 01:49 /dev/log -> /run/systemd/journal/dev-log
# ls -l /run/systemd/journal/dev-log
srw-rw-rw- 1 root root 0 Mar 9 01:49 /run/systemd/journal/dev-log
I have tried mounting /dev/log and /run/systemd/journal/dev-log, both produce
same errors:
from stdout:

This particular job i start from marathon and have the following definition
(if I change MESOS to DOCKER - it works):
"container": {
"type": "MESOS",
"volumes": [
{
"hostPath": "/run/systemd/journal/dev-log",
"containerPath": "/dev/log",
"mode": "RW"
}
],
"docker": {
"image": "xxxx",
"credential": null,
"forcePullImage": true
}
},
