Customize Hasura Docker Image - docker

Question

I have a need to install awscli and jq library in Hasura Docker Image. I tried to use yum, apt-get or apk commands to install the dependencies, but none of them worked.
Docker Image: https://hub.docker.com/r/hasura/graphql-engine/
how to install these dependencies in Hasura Docker Image? Any help is appreciated.
Dockerfile:
FROM hasura/graphql-engine:latest
COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh
CMD ["./entrypoint.sh"]
entrypoint.sh:
#!/bin/sh
set -o errexit -o nounset -o pipefail
DB_HOST=${DB_HOST:-postgres}
DB_PORT=${DB_PORT:-5432}
if [ -z "${DB_NAME}" ]; then
echo "Must provide DB_NAME environment variable. Exiting...."
exit 1
fi
if [ -z "${DB_USER}" ]; then
echo "Must provide DB_USER environment variable. Exiting...."
exit 1
fi
if [ -z "${DB_PASSWORD}" ]; then
echo "Must provide DB_PASSWORD environment variable. Exiting...."
exit 1
fi
export HASURA_GRAPHQL_DATABASE_URL=postgres://${DB_USER}:${DB_PASSWORD}#${DB_HOST}:${DB_PORT}/${DB_NAME}
/bin/graphql-engine serve
DB_PASSWORD is encrypted with KMS, so i want to use aws cli to decrypt the password in entrypoint.sh file before setting the Environment Variable: HASURA_GRAPHQL_DATABASE_URL

I was able to customize Hasura Docker Image with the help of Hasura Team support.
