Can't pull fsLayers Error on 2.4.0

[foobar888]

When I run the command line below:
docker run --env-file=klar.env ############.dkr.ecr.us-east-1.amazonaws.com/klar:latest ${REGISTRY}/nifi:latest

I get the following errors:

clair timeout 1m0s
docker timeout: 1m0s
no whitelist file
Can't pull fsLayers

My klar Dockerfile is defined as follow:

FROM golang:1.8-alpine as builder

RUN apk --update add git;
RUN go get -d github.com/optiopay/klar
RUN go build ./src/github.com/optiopay/klar

FROM python:alpine

RUN apk -uv add --no-cache groff jq less ca-certificates && \
    pip install --no-cache-dir awscli

COPY --from=builder /go/klar /klar

RUN aws ecr get-authorization-token --region us-east-1 && \
        eval $(aws ecr get-login --no-include-email --region us-east-1)

My klar.env is defined as follow:

CLAIR_ADDR=###.##.###.##:6060
CLAIR_OUTPUT=High
CLAIR_THRESHOLD=10
DOCKER_LOGIN=`aws ecr get-login --no-include-email --region us-east-1`
PASSWORD=`echo $DOCKER_LOGIN | cut -d' ' -f6`
REGISTRY=`echo $DOCKER_LOGIN | cut -d' ' -f7 | sed "s/https:\/\///"`
KLARE_TRACE=true
DOCKER_USER=AWS

And the docker-compose.yml to run Clair/Postgres is defined as follow:

version: '2.1'
services:
  postgres:
    container_name: clair_postgres
    image: postgres:9.6
    restart: unless-stopped
    environment:
      - POSTGRES_USER=clair
      - POSTGRES_PASSWORD=clair
      - POSTGRES_DB=clair

  clair:
    container_name: clair_clair
    image: quay.io/coreos/clair:latest
    restart: unless-stopped
    depends_on:
      postgres:
        condition: service_started
    ports:
      - "6060-6061:6060-6061"
    links:
      - postgres
    volumes:
      - /tmp:/tmp
      - ./clair_config:/config
    command: [-config, /config/config.yaml]

NOTE:
1. If I docker pull the image I would like to scan, it works
docker pull ############.dkr.ecr.us-east-1.amazonaws.com/nifi

2.To test all, I'm running everything in the same AWS EC2.

I wonder if it is an issue with Klar and or Clair/Postgres?

I would be grateful if someone could help me.

Thank you!

Please update klar.env to contain KLAR_TRACE=true (without E), it seems that Klar can't connect do docker registry.

@hashmap
Thank you very much!
In my case it was my fault: there was no such tag in my docker repo :)
