Quick and dirty script to check the number of images in ECR repositories and if there is an associated lifecycle policy

checkecr.sh

#!/bin/bash

RED='\033[0;31m'
GREEN='\033[0;32m'
NC='\033[0m' # No Color

REPOS=$(aws ecr describe-repositories --query 'repositories[*].repositoryName' | jq -r '.[]')

for r in $REPOS ; do 
    printf $r 

    COLOR=$GREEN
    IMAGES=$(aws ecr describe-images --repository-name $r --query 'imageDetails[*].imageDigest' | jq -r '.[]')
    IMAGES_COUNT=$(echo $IMAGES | wc -w)
    if [ $IMAGES_COUNT -gt 500 ] ; then
        COLOR=$RED
    fi

    printf " ${COLOR}$IMAGES_COUNT ${NC}"

    COLOR=$GREEN
    POLICY='policy'
    $(aws ecr get-lifecycle-policy --repository-name $r > /dev/null 2>&1)
    if [ $? != 0 ] ; then
        COLOR=$RED
        POLICY='no_policy'
    fi

    printf "${COLOR}$POLICY${NC}\n"
done
