Error trying to set up db-less kong using docker-compose - docker

Question

I am trying to set up kong db-less
I have created a docker file as below:
FROM kong
USER 0
RUN mkdir -p /kong/declarative/
COPY kong.yml /usr/local/etc/kong/kong.yml
USER kong
and a docker-compose file
version: "3.8"
networks:
kong-net:
services:
kong:
container_name: kong-dbless
build:
context: .
dockerfile: Dockerfile
restart: unless-stopped
networks:
- kong-net
environment:
- KONG_DATABASE=off
- KONG_ADMIN_LISTEN=0.0.0.0:8001, 0.0.0.0:8444 ssl
- KONG_PROXY_ACCESS_LOG=/dev/stdout
- KONG_ADMIN_ACCESS_LOG=/dev/stdout
- KONG_PROXY_ERROR_LOG=/dev/stderr
- KONG_ADMIN_ERROR_LOG=/dev/stderr
- KONG_DECLARATIVE_CONFIG=/usr/local/etc/kong/kong.yml
ports:
- "8001:8001"
- "8444:8444"
- "80:8000"
- "443:8443"
and kong.yaml is as below
_format_version: "1.1"
_transform: true
services:
- host: mockbin.org
name: example_service
port: 80
protocol: http
routes:
- name: example_route
paths:
- /mock
strip_path: true
I run docker-compose up but I errors in the log

Does anybody know what the problem is and how should I fix it?
Also I tried this but did not work:
Dockerfile
FROM kong
COPY kong.yml /
RUN cp /etc/kong/kong.conf.default /etc/kong/kong.conf
docker-compose
version: "3.8"
networks:
kong-net:
services:
kong:
container_name: kong-dbless
build:
context: .
dockerfile: Dockerfile
# restart: unless-stopped
networks:
- kong-net
healthcheck:
test: [ “CMD”, “curl”, “-f”, “http://kong:8000” ]
interval: 5s
timeout: 2s

environment:

- KONG_ADMIN_LISTEN=0.0.0.0:8001, 0.0.0.0:8444 ssl
