Getting error at the time of run .sh script from DockerFile - bash

Question

My DockerFile is :
FROM postgres:latest
VOLUME /var/lib/postgresql/data
ARG PG_POSTGRES_PWD=123qwe
ARG DBUSER=postgres
ARG DBUSER_PWD=123qwe
ARG DBNAME=docker_pg_sh
ARG DB_DUMP_FILE=gtma_latest.sql
ENV POSTGRES_DB docker_pg_sh
ENV POSTGRES_USER postgres
ENV POSTGRES_PASSWORD ${PG_POSTGRES_PWD}
ENV PGDATA /pgdata
COPY wait-for-pg-isready.sh /tmp/wait-for-pg-isready.sh
COPY ${DB_DUMP_FILE} /gtma_latest.sql
RUN set -e && \
nohup bash -c "docker-entrypoint.sh postgres & " && \
/tmp/wait-for-pg-isready.sh && \
psql -U postgres -c "CREATE USER ${DBUSER} WITH SUPERUSER CREATEDB CREATEROLE ENCRYPTED PASSWORD '${DBUSER_PWD}';" && \
psql -U ${DBUSER} -d ${POSTGRES_DB} -c "CREATE DATABASE ${DBNAME} TEMPLATE template0;" && \
pg_restore -v --no-owner --role=${DBUSER} --exit-on-error -U ${DBUSER} -d ${DBNAME} </gtma_latest.sql && \
psql -U postgres -c "ALTER USER ${DBUSER} WITH NOSUPERUSER;" && \
rm -rf /gtma_latest.sql
HEALTHCHECK --interval=30s --timeout=30s --start-period=5s --retries=3 \
CMD pg_isready -U postgres -d docker_pg_sh
and wait-for-pg-isready.sh file is :
#!/bin/bash
set -e
get_non_lo_ip() {
local _ip _non_lo_ip _line _nl=$'\n'
while IFS=$': \t' read -a _line ;do
[ -z "${_line%inet}" ] &&
_ip=${_line[${#_line[1]}>4?1:2]} &&
[ "${_ip#127.0.0.1}" ] && _non_lo_ip=$_ip
done< <(LANG=C /sbin/ifconfig)
printf ${1+-v} $1 "%s${_nl:0:$[${#1}>0?0:1]}" $_non_lo_ip
}
get_non_lo_ip NON_LO_IP
until pg_isready -h $NON_LO_IP -U "postgres" -d "docker_pg_sh"; do
>&2 echo "Postgres is not ready - sleeping..."
sleep 4
done
>&2 echo "Postgres is up - you can execute commands now"
Both file are in same folder.
But when I run the command docker build -t gmta-test-sh-vol:1.0.0 . , I am getting error
like this :
Step 14/15 : RUN set -e && nohup bash -c "docker-entrypoint.sh postgres & " && /tmp/wait-for-pg-isready.sh && psql -U postgres -c "CREATE USER ${DBUSER} WITH SUPERUSER CREATEDB CREATEROLE ENCRYPTED PASSWORD '${DBUSER_PWD}';" && psql -U ${DBUSER} -d ${POSTGRES_DB} -c "CREATE DATABASE ${DBNAME} TEMPLATE template0;" && pg_restore -v --no-owner --role=${DBUSER} --exit-on-error -U ${DBUSER} -d ${DBNAME} </gtma_latest.sql && psql -U postgres -c "ALTER USER ${DBUSER} WITH NOSUPERUSER;" && rm -rf /gtma_latest.sql

The command '/bin/sh -c set -e && nohup bash -c "docker-entrypoint.sh postgres & " && /tmp/wait-for-pg-isready.sh && psql -U postgres -c "CREATE USER ${DBUSER} WITH SUPERUSER CREATEDB CREATEROLE ENCRYPTED PASSWORD '${DBUSER_PWD}';" && psql -U ${DBUSER} -d ${POSTGRES_DB} -c "CREATE DATABASE ${DBNAME} TEMPLATE template0;" && pg_restore -v --no-owner --role=${DBUSER} --exit-on-error -U ${DBUSER} -d ${DBNAME} </gtma_latest.sql && psql -U postgres -c "ALTER USER ${DBUSER} WITH NOSUPERUSER;" && rm -rf /gtma_latest.sql' returned a non-zero code: 127
But there is no error when the line for copy the file wait-for-pg-isready.sh is running .
How can the problem will be solved?
Thanks in advance.
