Question

我的DockerFile是：

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

和wait-for-pg-isready.sh文件是：

#!/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"

两个文件都在同一文件夹中。

但是当我运行命令docker build -t gmta-test-sh-vol:1.0.0 .时，出现错误像这样：

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
---> Running in a791e734c6df

但是当复制文件wait-for-pg-isready.sh的行正在运行时，没有错误。该如何解决？预先感谢。

从DockerFile运行.sh脚本时出现错误
