dpage/pgadmin4 container failed in rancher/kubernetes , but works directly from dockerd

Hello to everyone ,

my environment:
Ubuntu 16.04.6 LTS 4.4.0-154-generic #181-Ubuntu SMP Tue Jun 25 05:29:03
UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Docker version 18.09.7, build 2d0083d
rancher v2.2.4

if I start container as :
docker run -p 8000:80 -e "PGADMIN_DEFAULT_EMAIL=mymail" -e
"PGADMIN_DEFAULT_PASSWORD=secret" -d dpage/pgadmin4

it works just fine
But if I try to deploy workload from rancher/kubernets , it continuously
restarts with errors, logs are below.
How could I fix it ?

docker logs df2537dfb02d
