Docker image is broken if container runtime is Containerd

[youngwookim]

Affected Version

Druid version <= 0.20.2

Description

Current docker image created a symlink for the home directory /opt/druid This causes CrashLoopBackOff on kubernetes cluster that has the Containerd as a container runtime. Got error messages from pod:

(snip)

mkdir: cannot create directory ‘var/tmp’: Permission denied
mkdir: cannot create directory ‘var/druid’: Permission denied
mkdir: cannot create directory ‘var/druid’: Permission denied
mkdir: cannot create directory ‘var/druid’: Permission denied
mkdir: cannot create directory ‘var/druid’: Permission denied
mkdir: cannot create directory ‘var/druid’: Permission denied

I've tested with GKE, kubernetes 1.18 + Containerd as a container runtime.
